4906-17-02 PROJECT SUMMARY

General Procedural Information:

Hardin Wind Energy LLC (the Applicant), an affiliate of Invenergy Wind Development LLC

(Invenergy), is certified to construct the Hardin Wind Farm (the Project), a wind-powered electric generation facility to be located in Hardin County, Ohio. The Applicant is aware that the new rules are in effect, but inasmuch as the Application to which this Third Amendment refers was filed under the rules in existence before December 11, 2015, this Third Amendment application tracks the designations of the older rules. Applicant believes that it has addressed substantive changes in the new rules.

Applicant takes the position that this Third Amendment falls squarely within the precedent of the decision in Case No. 14-1591-EL-BGA, In the Matter of the Application of Black Fork Wind

Energy, LLC Regarding Its Certificate of Environmental Compatibility and Public Need in Case

No. 10-2865-EL-BGN issued on August 27, 2015 (“Black Fork Amendment Case”). In the

Black Fork amendment application, as in this Third Amendment, Black Fork was seeking only to change turbine models and not to make any other changes. The Ohio Power Siting Board (OPSB or Board) noted that the Black Fork amendment merely sought to upgrade the turbine models in order to take advantage of the latest technological advances (at 6) and that its decision was

“concentrated solely on the Applicant’s request to add two new turbine models. . .” and that

“there is no material increase in any environmental impact of the facility and no change in any portion of the facility’s location, including the location of the individual turbines, from what was originally approved by the Board in the Black Fork Amendment Case.” Id at 6. The Board concluded in the Black Fork Amendment Case that though Black Fork was required to file an application for an amendment, the Board considers the facts of the case and whether the

Section 4906-17-02 1 10015520v7 Hardin Wind Energy LLC Application for Third Amendment March 2016 provisions of Ohio Revised Code Section (“R.C.”) 4906.201 should be triggered. It found that based upon that facts that the Black Fork Amendment Case did not request that any turbines be relocated nor did it proposed any new or additional environmental impacts beyond those previously approved, the application did not constitute an amendment as that term is used in R.C

4906.201 (B)(2). Id. at 7. The Applicant is filing this Third Amendment, as did the applicant in the Black Fork Amendment Case, so that the Board Staff can review it to make the determination that the precedent of the Black Fork Amendment Case may be followed.

As explained above, Applicant does not believe that this Third Amendment triggers R.C.

4906.201, but if R.C. 4906.201 were to apply, the Applicant additionally meets the requirements of that statute:

• The sole purpose of this Third Amendment is to make changes to one or more turbines

that have been approved under Applicant’s existing certificate, but have not yet been

installed;

• This Third Amendment does not increase the number of turbines to be installed as set

forth in the Certificate;

• The Applicant is seeking the amendment within 180 days of the effective date of the

legislation, Ohio House Bill 64, effective September 29, 2015;

• The turbine to be installed is more efficient and more technologically advanced than the

type approved in the Applicant’s Certificate;

• The turbine proposed to be installed is not more than 8% taller as measured from its base

to the tip of the highest blade, than the turbines approved in the First Amendment; Case

No. 11-3446-EL-BGA;

Section 4906-17-02 2 10015520v7 Hardin Wind Energy LLC Application for Third Amendment March 2016

• The Applicant is obligated by contract to provide wind energy to at least one mercantile

customer that consumes 7,000,000 kW hours; and

• The turbines will be installed on the same turbine locations as were approved under

Applicant’s Certificate.

Applicant Update:

Hardin Wind Energy LLC (the Applicant), an affiliate of Invenergy Wind Development LLC

(Invenergy), is certified to construct the Hardin Wind Farm (the Project), a wind-powered electric generation facility to be located in Hardin County, Ohio. The original Application (the

Application) for a Certificate of Environmental Compatibility and Public Need (the Certificate) was filed on July 10, 2009. Applicant filed an amended application on September 18, 2009 (the

Application) which was processed using the same case number. The Board issued an Opinion,

Order and Certificate in Case Number 09-479-EL-BGN on March 22, 2010 for the construction of a 300 megawatt (MW) wind farm consisting of up to 200 wind turbines at the Hardin Wind

Farm in Hardin County, Ohio

On June 3, 2011, Applicant filed an amendment in Case No. 11-3446-EL-BGA (First

Amendment) which the OSB approved on August 29, 2011. The Order on the First Amendment permitted the Applicant to construct the Project in three phases and to use taller turbines in accordance with a modified plan.

On June 5, 2014, Applicant filed a Second Amendment, Case No 14-1030-EL-BGA, which it later withdrew and the OPSB dismissed it on November 12, 2105.

The Applicant seeks to further amend the Certificate through this Amendment (Third

Amendment). This Third Amendment does not change the phases as approved by the Board when it approved the First Amendment.

Section 4906-17-02 3 10015520v7 Hardin Wind Energy LLC Application for Third Amendment March 2016

(A) Project Summary and Facility Overview

Since filing of the First Amendment application, General Electric (GE) has introduced new turbine models that are more efficient and cost effective than the turbines approved in the First

Amendment. The Applicant proposes to build the project using a GE turbine, Model 2.3-116; however, the approved turbine site locations will not change.

Through this Amendment, the Applicant is proposing to amend the Certificate to change to the

General Electric turbine listed in Table 03-02. With the new turbine model proposed, the total capacity of the Hardin Wind Farm will not exceed the 300 MW permitted under the Certificate.

(1) General Purpose of the Facility

No change.

(2) Facility Description

No change.

(3) Site Selection Process

No change.

(4) Principal Environmental Considerations

No change.

(5) Project Schedule

With the exception of preparation of Final Design and Financing, which will occur in

Third Quarter and Fourth Quarter of 2016, the Facility Construction, expected to begin

during the Fourth Quarter of 2016; and the Commercial Operations are planned for the

Fourth Quarter of 2017, no change.

4906-17-03 PROJECT DESCRIPTION AND SCHEDULE

(A) Proposed Facility Description

(1) Project Description

a. Types of Turbines

The Applicant is proposing to build the Project using the GE 2.3-116 wind

turbine.

b. Area Requirements

The impacted area will be greater during construction than during operation of the

wind farm. Estimated area required during construction and operations are each

summarized in Table 03-01.

Table 03-01. Estimated Area To Be Disturbed Project Area Area of Area of Total Total 35,900 Temporary Permanent Quantity Temporary Permanent Total Acres Disturbance Disturbance Disturbance Disturbance 2.9 acres per 0.04 acres per Turbines 118 turbines 342 acres 4.7 acres turbine turbine Access roads 75 feet wide 20 feet wide 34.4 miles 312.6 acres 83.3 acres Cables 30 feet wide None 45 miles 163.3 acres None Transformer 2 acres 2 acres 1 unit 2 acres 2 acres substation Interconnection 6 acres 6 acres 1 unit 6 acres 6 acres substation O&M building 6 acres 6 acres 1 unit 6 acres 6 acres and parking lot Laydown area 10 acres None 1 unit 10 acres None Permanent 0.55 acres / meteorological None 3 units 1.7 acres None met tower tower TOTAL 843.6 acres 102 acres Average per 7.2 acres 0.9 acres wind turbine

Section 4906-17-03 5 10015520v7 Hardin Wind Energy LLC Application for Third Amendment March 2016

Notes: 1. During construction, the wind turbine assembly area will generally be a circular

area with a radius of 200 feet or less. The following construction activities will

take place within this area: foundation excavation and construction, crane pad

construction, component laydown and assembly.

2. During operation, the wind turbine footprint will include the turbine base and a

gravel apron approximately 15 feet wide.

3. The access road construction disturbance width includes area for a gravel

roadway and road shoulders to accommodate movement of the main erection

crane, area for topsoil stockpiles, and area for cable routes beside the road.

4. The access road disturbance width during operation includes area for a gravel

roadway and road shoulders.

5. The cable route construction disturbance width includes room for the actual cable

cut for machines needed to install the cable. The width in the table is the average

width for all cable circuits. Widths may be wider in corridors where more than

one circuit is installed and narrower in corridors with only one circuit. The

calculation of total area impacted temporarily for cable corridors conservatively

over estimates cable disturbances by assuming that no cable routes are in the road

disturbance area.

6. Area disturbances of substation, switchyard, and O&M building are assumed to

be the same as during construction.

7. Average area disturbance per turbine does not include the stationary areas for the

substation, O&M building, and laydown yard.

Section 4906-17-03 6 10015520v7 Hardin Wind Energy LLC Application for Third Amendment March 2016

8. The Applicant may be installing up to three permanent meteorological towers to

monitor wind resources during operations. These permanent meteorological

towers will require access roads and underground utilities for their installation.

After construction, the roads will be re-graded and reseeded.

9. At the intersection of the access roads and public roads the turning radius will be

larger than that of typical public roads to accommodate the wind turbine

component delivery vehicles. This area will be re-graded and reseeded after

construction.

10. Temporary disturbances occur during project construction; permanent

disturbances are those that exist during project operation after construction is

complete.

As shown in Table 03-01, the Project would disturb approximately 2.3% of the Project area during construction and 0.2% of the Project area permanently. Table 03-01 is based on the

Project using 118 wind turbines. The areas in this section are conservative estimates that are provided to illustrate the maximum expected area disturbances. Actual disturbed areas should be less.

(2) Description of Equipment

The proposed wind turbines are similar to the GE 1.6-100 that was approved in the First

Amendment. The differences between the proposed GE 2.3-116 turbine and the GE 1.6-

100 turbine are summarized in Table 03-02 below.

2 General Safety Principles

The GE Wind Energy 1.x Series Wind Turbine Generator System (WTGS) has been built according to recognized safety rules.

Hazards for the user or third parties and impairment of the wind turbine generator system and other property may nevertheless arise during the use of this facility if it is

• operated by untrained or uninstructed staff • not used properly • improperly maintained or serviced

The owner / operator responsible for the WTG must ensure that

• The safety manual and the operating manual are available and are complied with • The service conditions and technical data are complied with • The protective devices are used • The prescribed maintenance work is carried out • The maintenance personnel are immediately informed or the plant immediately shut down if higher temperatures, noise, vibration, etc. compared to operation at normal rating should occur.

The operating manual contains the information required for operation of the WTG by qualified personnel.

The warranty of the manufacturer is only provided if the currently valid operating manual is observed and complied with.

Take precautions against malfunctions and thereby prevent personal injury or death and material damage!

2.1 Personnel Groups

Different personnel groups are specified for carrying out the various tasks in and on the WTG. Before work is started, it must be ensured that the personnel in question have the requisite qualifications to carry out the respective tasks. If necessary, suitable training or qualification measures are required, or the work is carried out by other personnel with a suitable qualification.

2.1.1 Qualified Persons Work on electrical equipment and machinery may only be carried out by qualified persons who are familiar with the currently applicable safety and installation regulations. The qualified persons must be authorized to carry out the requisite tasks by the person responsible for safety in the WTG under the health and safety regulations. A qualified person is a person who

• has appropriate training and experience • is familiar with the currently applicable standards, regulations and accident prevention regulations and generally recognized code of practice • has been instructed in the operating principle and service conditions of electrical and mechanical drive systems and • can recognize and avoid dangers

Unqualified persons may not be deployed.

2.1.2 Technically Competent Persons Technically competent persons are persons who have the requisite technical knowledge for the inspection of work equipment as a result of their professional training, their professional experience and their current professional activity.

2.1.3 Experienced Persons An experienced person is someone who, on the basis of his technical training and experience, has gained adequate knowledge in the particular field of the equipment/device to be tested and who is acquainted with the pertinent national industrial safety legislation, the regulations for the prevention of accidents, directives and generally accepted engineering standards (DIN standards, VDE regulations, technical rules of other member states of the European Union or other contracting states of the agreement concerning the European Economic Area as well as OSHA/ANSI/NFPA/CSA and other standards and regulations for the Americas) to the extent that he is able to assess the safe working order of the equipment/device concerned.

2.1.4 Experts Experts are persons who are familiar with the relevant industrial safety regulations, directives and generally recognized code of practice and can verify and authoritatively assess the presence of threats and dangers.

2.2 Proper Use

The GE Energy 1.x Series Wind Turbine Generator Systems are intended solely for the generation of electrical power by means of wind energy.

Any other use or use extending beyond this is deemed to be improper. The operator / owner of the WTG bears the sole responsibility for any damage resulting there from.

The same also applies to any unauthorized modifications made to the WTG. As a general principle, modifications to the WTG may be carried out only after consultation with GE Energy, in order to guarantee the safety and the correct functioning of the WTGS.

Proper use also includes compliance with the information on

• Safety • Operation • Service and maintenance provided in the technical documentation of the WTGS.

2.3 General Information

The wind turbine generator system may only be used in a technically perfect condition in line with the technical documentation. In addition, it must be used as intended, as well as with safety in mind and with an awareness of the dangers. Any malfunctions, particularly those which could impair safety, must be reported and remedied immediately.

Anybody who has been authorized to carry out erection, commissioning, operation or maintenance work must have read and understood the complete operating manual, in particular the safety manual.

It is too late to read the manual while carrying out the work. This applies especially to personnel who are only occasionally deployed on the wind turbine generator system.

The operating manual must be readily available at the site of operation of the wind turbine generator system at all times. It is kept in the main cabinet of the WTG.

The relevant regulations for the prevention of accidents (see "Information for the Operator" in "Basic information regarding the operating instructions manual") and any other generally recognized safety and industrial health regulations must also be complied with.

We cannot be held liable for any damage or accidents as a result of non-compliance with the operating instructions, the relevant regulations for the prevention of accidents and any other generally recognized safety and industrial health regulations.

Responsibilities for the different activities within the framework of operation, service and maintenance of the WTG must be clearly defined and complied with. This is the only way to prevent mistakes, particularly in dangerous situations.

The instructions for

• Shutting down the WTG • Maintenance work • Handling the rotor lock • Entering the rotor hub must be followed during the inspection, maintenance and repair of the wind turbine generator system and the safety devices.

4 Information for the Operator / Owner of the Wind Turbine Generator System

The operator of the WTG is responsible for ensuring that no unauthorized persons remain inside or on the WTG. The WTG must be kept locked to prevent this.

The wind turbine generator system may only be started up if it has been completely assembled and is in working order.

The wind turbine generator system may only be operated if all safety equipment and safety-relevant devices, e.g. detachable protective equipment, are in place and operational.

If any malfunctions occur or if ice builds up on the rotor blades, the wind turbine generator system must be shut down immediately and secured. Malfunctions are to be remedied without delay by trained technical personnel.

In the case of malfunctions which are not automatically reset by the control system of the WTG, GE Energy must be contacted before a restart is carried out, in order to confirm that the WTG may be placed in the automatic operating mode (i.e. whether the WTG may be restarted).

Follow the switch-on and shut-down procedures and take note of the visual and monitoring displays in accordance with the operating manual!

In addition to this, the operator/owner of the WTG must comply with the following additional safety instructions (if maintenance is not carried out by GE Energy employees):

• If the WTG is not directly connected to the public telephone system, the maintenance personnel must have a cell phone or radio with them when ascending the tower. • The personnel must be informed about who to contact in an emergency. (Telephone numbers of a rescue center, police, fire department...) • For safety reasons, the personnel must be instructed that the WTG may only be entered by a minimum of two persons. • Special authorization from GE Energy is required to carry out inspection and maintenance work inside a WTG while it is in operation. • The personnel must be instructed to keep the WTG escape routes clear at all times when carrying out work as a part of maintenance or operation. • In the case of work involving a fire hazard, the personnel must have a fire extinguisher ready at hand, in order to be able to immediately extinguish any fire that may start. • Personnel are not permitted to remain at a higher level in the WTG while work involving a fire hazard is being carried out. • Personnel instructed to carry out work in or on the WTG must be provided with instructions and the appropriate personal protective equipment (PPE). • The WTGS must only be entered when a second person is available to provide assistance or call for help in case of accident.

• If the WTG is part of a wind farm and connected to a wind power plant, this safety manual must be supplemented in cooperation with the local power supply company, so that it also: — describes the safety aspects relevant to the wind farm — describes the exchange of information and names the persons who are to be contacted — describes access to basic first aid facilities

5 Signs to be attached by the Operator/Owner

The operator/owner of the WTG is obliged to attach additional warning signs to the WTG. These are intended to cover safety aspects which are not related to the scope of supply of the manufacturer of the WTG.

The warning signs must state that

• It is dangerous and prohibited for unauthorized persons to enter or climb the WTG • It is prohibited to remain in the vicinity of the WTG while work is being carried out outside the nacelle • Deposits of ice which have formed on the rotor blades (depending on the location of the WTG) could drop off

The operator/owner is responsible for seeing that any components or plant components which he has supplied are properly equipped with signs.

6.3 Protective Equipment for Measurements on Live Components

Danger! Electricity! Contact can cause extremely serious injuries and even death.

Danger! Life-threatening hazard!

Special PPE is required for measurements on live components. This provides protection against electricity flowing through the body, e.g. as a result of touching live components in operation. Furthermore, it provides protection against accidental arcs caused by insulation breakdowns e.g. as a result of switching operations under load.

Refer to NFPA 70E document (GE Standard) for further guidance on PPE requirements for electrical work.

6.4 Hooking Points

As a rule, the hooking points are marked in yellow and are designated with a statement of the permissible safe work load. These hooking points are to be used with a safety harness and lanyard with a shock absorber to provide protection in areas where there is a danger of falling.

Exchange of the rail

The nose cone rail and nacelle rail must be exchanged after any Attention! fall!

6.5 Abseiling Device

Not all wind turbine generator systems are supplied with an abseiling device. There is sometimes only a certain number of devices, especially in larger wind farms.

The abseiling device (e.g. abseiling device AG 10 K – RK Sicherheitstechnik) has a rope which is long enough for the respective height of the tower of the WTG.

The abseiling device is stored in a lead-sealed equipment bag, which is located in a net beside the hatchway to the roof of the nacelle.

Fig. 11: Equipment bag in the net The abseiling device is used by the personnel to abseil from high workplaces. It is not a fall arresting device, instead it is used primarily for the evacuation of personnel in the event of an accident or fire. In case of fire, it can be used to abseil from the roof of the nacelle of the WTG as a 2nd escape route.

As a rule, the hooking points for the abseiling device are marked in yellow and are designated with a statement of the permissible safe work load. The abseiling device is attached to the hooking point by means of a snap hook or to the roof rail by means of a sling rope and a snap hook.

Danger of accident with a defective abseiling device! In an emergency, your life could depend on the abseiling device working properly! As a result, check the integrity of the seal of the equipment bag on each visit to the nacelle. The abseiling device is pre-assembled and is Attention! ready for use immediately after it has been removed from the equipment bag. Carry out an additional visual inspection of the abseiling device immediately before use.

It is easy to operate the abseiling device incorrectly in emergency situations. As a result, ensure that you know how to operate the device and are familiar with the abseiling operation. Please also read the operating manual. This is the only way to ensure that the correct maneuvers are carried out in an emergency.

6.5.1 Abseiling from the Roof of the Nacelle Abseiling can take place individually or in pairs. The abseiling device may be loaded with a maximum of 225 kg up to a rope pitch of 100 m. Abseiling takes place at a speed of 0.7 m/s. The abseiling speed is regulated by means of a centrifugal brake.

A typical abseiling operation is described in the following. The procedure described may vary depending on the abseiling device. As a general principle, always follow the instructions of the manufacturer of the respective abseiling device!

1. Make sure that your safety harness is put on correctly. 2. Secure yourself against falling by means of the lanyard. Attach the lanyard to tie-off points or nacelle rail. Step out on the roof of the nacelle. 3. Close the roof hatch. 4. Break the lead seal on the equipment bag. 5. Remove the abseiling device from the equipment bag. Leave the rope in the equipment bag.

6. Attach the abseiling device to the roof rail of the nacelle by means of the sling rope and the snap hook. 7. Secure the snap hook with the clamping nut. 8. Throw down the equipment bag with the rope.

Fig. 12: Abseiling device

9. Check the condition and the correct functioning of the device.

10. Check the rope for loops and knots.

Interruption of abseiling through loops or knots! Loops or knots in the rope prevent abseiling, since the rope cannot run through the abseiling device if it has a knot. As a result, always check the rope carefully! Danger! REMOVE ALL LOOPS AND KNOTS FROM THE ROPE BEFORE YOU START ABSEILING!

11. Hook the snap hook on the short end of the rope into the two chest rings of your safety harness.

12. Sit in front of the roof rail on the edge of the nacelle.

13. Ensure that the length of rope between the chest rings of your safety harness and the abseiling device is pulled taut.

14. Release the lanyard attached for your safety.

15. Slowly put your weight on the rope of the abseiling equipment. After you have let go of the nacelle and the roof rail, you will abseil at a speed of 0.7 m/s.

16. After you have reached the ground, immediately release the snap hook from the chest rings of your safety harness.

17. A second person waiting on the roof can then hook in the snap hook of the end of the rope which is now at the top and abseil as described. The rope may have to be pulled through until the snap hook arrives at the top.

18. The device must be inspected by a technically competent person after a rescue or an abseiling exercise.

6.5.2 Care and Maintenance of the Abseiling Device The textile components of the abseiling equipment may only be cleaned by the manufacturer.

If damage to the rope, snap hook or abseiling device is discovered, the escape equipment must be withdrawn from use and inspected by the manufacturer.

Under normal service conditions, a service period of 4-6 years can be assumed for the textile ropes.

The abseiling device must be inspected by a technically competent person or by the manufacturer after a rescue or an abseiling exercise or at the intervals recommended by the manufacturer at the latest.

6.6 Fire Extinguishers (optional feature)

Fire extinguishers are optional in the wind turbine generator systems (WTG). If fire extinguishers are supplied, the WTG is normally provided with a fire extinguisher in the tower and in the nacelle.

The locations of the fire extinguishers are identified by this sign.

Danger: Electricity! De-energize the installation before using the fire extinguisher. After actuation of the medium-voltage circuit-breaker, keep a safe distance of at least one meter from the fire when extinguishing! Danger! The fire extinguisher may only be used on electrical installations up to 1000V!

Ensure that you are familiar with the function and the operation of the fire extinguisher. Only thus can you act quickly and purposefully in emergency situations.

The use of fire extinguishers must be practiced. The personnel deployed in the WTG must therefore be trained in fire-fighting at regular intervals.

The fire extinguishers must be regularly inspected by a technically competent person in accordance with the national regulations. A record of the check with the date must be permanently affixed to the appliance in an easily visible location. The directions for use (on the fire extinguisher) must be followed before fire-fighting.

6.7 First Aid

First aid is used for the initial treatment of an accident victim until the arrival of a doctor or until transport to a hospital, in order to avert a life-threatening situation or to prevent secondary injury.

There is a legal obligation to carry out rescue measures provided that this is possible without considerable self-endangerment.

The plant may never be entered alone, so that a second person can send an emergency call. If the interphone has a landline connection, the emergency call can be made via the interphone. An operational cellphone is to be carried at all times, in order to be able to ensure rapid assistance in an emergency.

Proceed as follows in the case of an accident:

1. Keep CALM! 2. In the case of serious accidents and injuries, notify a rescue center by interphone, cell phone or radio. 3. Render first aid immediately. 4. Secure the scene of the accident. 5. Report all accidents (near-accidents, minor accidents, serious accidents) to your immediate supervisor. Also notify the EHS department of GE Energy.

Keep access to the WTG clear! The access roads to the plant must be kept clear at all times and be negotiable by car, in order to guarantee rapid and problem-free ATTENTION! first aid in an emergency.

First Aid Box (Optional) The provision of wind turbine generator systems (WTGS) with first aid boxes is optional.

If provided a first aid box is located in the nacelle of the wind turbine generator system for the treatment of minor injuries. Any material removed is to be replaced immediately after use.

This sign identifies the location of the first aid box in the nacelle.

7 Safety Devices

The safety devices of the WTG comply with the requirements of the following standards:

• DIN EN ISO 13857: 2008 - 06 – Safety distances to prevent danger zones from being reached by the upper limbs and lower limbs. The unauthorized removal or the overriding (by-passing) of safety devices is a punishable offence. Any liability claim is invalid in the case of damage.

Any point at which danger can arise and all drive units are provided with protective covers, which can only be undone and removed by means of tools. These protective covers may only be removed by qualified staff and only for the performance of service and maintenance or repair work. The protective covers are to be refitted immediately after completion of the work.

The owner / user of the WTG and the personnel deployed by him for operation, maintenance and repairs bear the responsibility for an accident-free work process.

7.1 Emergency Stop Pushbuttons

Any power-operated work equipment with dangerous movements must have one or - if necessary - several emergency control units for the prevention or reduction of an imminent or arisen danger, by means of which the dangerous movements can be stopped or rendered ineffective in another manner.

The emergency stop pushbuttons are not dependent on electronic logic.

Emergency stop pushbuttons (red mushroom pushbutton on a yellow base) are located on the control cabinet, the top box in the nacelle and the control cabinet in the hub. Fig. 14: Emergency stop pushbutton

The EMERGENCY STOP pushbutton may only be pressed in situations, in which the safety of personnel or the WTGS and its components is threatened.

Pressing the emergency stop pushbutton causes the safety chain to open, and the rotor of the WTG is brought to a standstill via emergency braking. Initiation of the safety chain causes the rotor blades to travel to the feathering position in the [emergency] battery mode! In addition to this, the WTG is de-energized except for the control voltage.

7.2 Rotor Lock

The GE 1.x series plants are equipped with two rotor locks.

7.2.1 Rotor Lock on the High-speed Shaft The rotor lock on the high-speed shaft is located on the brake disk of the outgoing shaft of the gearbox. It must be engaged during all regular maintenance work on the drive train and for the physical inspection of the rotor hub.

Maintenance work on the drive train which requires the rotor shaft to be locked may only be carried out at wind speeds up to 15 m/s.

Maintenance work in the rotor hub may only be carried out at average wind speeds of less than 15 m/s. In this connection, the rotor lock on the high-speed shaft must be engaged. The rotor lock on the low-speed shaft must not be engaged.

If the turbine is unable to idle after a malfunction, the lock on the high-speed shaft must be engaged. It must be ensured that all three rotor blades are in the feathering position.

Engaging the Rotor Lock on the High-speed Shaft 1. Manual stop 2. Remove the locking pin of the rotor lock and advance the rotor lock as far as possible by means of the crank 3. If necessary, briefly actuate the "rotor brake" switch on the top box, in order to disengage the brake for a short time, thereby placing the brake disk in a better position. 4. Fully engage the rotor lock until the locking pin locks home again at the lower position.

7.2.2 Rotor Lock on the Low-speed Shaft A lock is located on the rotor shaft flange of the low-speed shaft. This is only used for carrying out special work on the drive train. A sliding block or a sliding bolt which is guided in a fixture on the base frame is pushed onto the shaft flange in grooves or holes. The limit switch in the safety loop is opened as a result.

The rotor lock on the low-speed shaft may only be engaged up to the following average wind speeds:

• 8 m/s in the welded frame version up to 2004 (individual gusts up to a max. of 14 m/s) • 12 m/s in the 1.5-82.5 (individual gusts up to a max. of 19 m/s). • 15 m/s in the cast frame version and in the welded frame version from 2005 (individual gusts up to a max. of 24 m/s)

The current wind speed can be read on the SCADA display!

Engaging the Rotor Lock on the Low-speed Shaft 1. Manual stop 2. Manually turn the blades to the 0 degree position 3. Position the rotor to engage the lock 4. Engage the rotor lock on the high-speed shaft 5. Actuate the service switch to disconnect the battery in the rotor hub 6. Engage the rotor lock on the low-speed shaft 7. If necessary, release the lock on the high-speed shaft after leaving the hub.

If the wind speed unexpectedly increases, any installation work must be ended immediately, and the rotor lock must be disengaged in the reverse sequence.

Leaving the WTG with the rotor lock applied is strictly prohibited! ATTENTION!

8 Residual Risks

Even if all the safety requirements are complied with, a residual risk remains during operation of the GE Energy 1.x Series wind turbine generator systems.

Anyone who works on and with the WTG must be aware of these residual risks and follow the instructions which prevent these residual risks from resulting in accidents or damage.

Danger of injury during ascent! The full-body safety harness must be put on and attached to the safety rail by means of the travelling safety hook during the ascent to the nacelle, in order to prevent the person ascending from falling. Any oil or grease deposits on the ladder must be removed Danger! immediately to prevent anyone from slipping while using the ladder. Ensure that your footwear is clean!

Falling objects hazard warning! An object may be unknowingly and unintentionally dropped and hit and cause injury to somebody. For this reason, only one person at a time may climb a section of the ladder between two platforms. The hatch covers must be Warning! closed again immediately after they have been passed through. Tools and equipments must be secured while climbing and transitioning to the nacelle roof or the hub.

Life-threatening hazard - working under suspended loads! Never stand under suspended loads. Danger!

Danger of falling from the nacelle! The nacelle has a roof hatch for accessing the hub. You are exposed to strong winds when climbing out through the hatch. Danger! Attach your lanyard to the outside rail from inside the nacelle. Climbing out is only allowed at wind speeds up to 15 m/s.

As a general principle, there is a falling hazard at all higher locations / workplaces.

8.1 Special Dangers – Electric Power

Note the following rules when carrying out any work on the electrical components of the plant, e.g. assembly, connection, opening of a device, maintenance:

1. DISCONNECTION 2. SECURE against re-connection, following proper Lock Out/Tag Out (LOTO) procedures 3. Ascertain safe isolation from supply 4. Ground and short-circuit 5. Cover up adjacent live components or provide them with barriers

In addition, ensure that all drives are at standstill.

Caution! Danger from electrical voltage! When switched on, electrical installations and machinery have live exposed conductors or rotating parts. They could therefore cause personal injury or death and material damage if the cover and the prescribed safety devices are removed, or in the event of incorrect handling and maintenance and in the case of improper use. The above stated safety regulations must therefore be complied with, particularly when removing a cover. In addition to this, electrical energy is still present in devices with power electronics even after the supply voltage to the device has Danger! been switched off. These devices are secured against unauthorized access. After waiting an appropriate time for the device to discharge (e.g. capacitors), always check for residual voltage before starting work. FOLLOW THE RESPECTIVE LOCKOUT/TAGOUT INSTRUCTIONS! (cf. Chapter 13)

In the case of malfunctions of the energy supply of the wind turbine generator system, actuate the EMERGENCY STOP button immediately if the plant has not already been switched off by the automatic control system.

Only use original fuses with the prescribed amperage!

In the case of repairs, care should be taken that design features are not modified, so that safety is compromised (e.g. leakage distances and sparking distances in air) and that distances are not reduced by insulation materials.

As a general principle, maintenance work may only be carried out by two persons, so that the second person can actuate the EMERGENCY STOP button in an emergency.

Only use insulated and approved tools.

The control system and interlocking as well as the monitoring and protective functions (thermal motor protection, speed monitoring, over current, fault to ground, etc.) may not be set out of function, even during a test run.

8.2 Special Dangers – Hydraulic System

For maintenance work on the hydraulic system, maintenance staff must be completely acquainted with the hydraulic circuit diagram and must have been instructed about its function and the possible consequences of an operating error.

Prior to any work on the hydraulic accumulators, it must be ensured that the accumulator circuits have been depressurized. The shut-down device is clearly marked and independent of the system management.

Danger through stored residual hydraulic energy!

FOLLOW THE RESPECTIVE LOCKOUT/TAGOUT INSTRUCTIONS! (cf. Danger! Chapter 13)

8.3 Special Dangers - Noise

The A-weighted equivalent continuous sound intensity level in the tower and the nacelle exceeds the permissible 70 dB(A) (per European Standard EN 50308) or the permissible 85 dBA TWA (per OSHA 29 CFR 1910.95) during operation. For some work, it may be necessary to place the WTG in operation or carry out a test run while personnel are in the nacelle.

Anybody carrying out work in the tower or the nacelle when the WTG is in operation must wear hearing protection with an appropriate level of noise protection as part of their personal protective equipment.

8.4 Special Dangers - Icing

8.4.1 Ice Build-up on the Rotor Blades Ice build-up on wind turbine generator systems (WTG) and, in particular, the shedding of ice from rotor blades can lead to problems if wind turbine generator systems are planned in the vicinity of roads, car parks or buildings at locations with an increased risk of freezing conditions, unless suitable safety measures are taken.

If people or objects near the wind turbine generator system (within the distance R*) could be endangered by pieces of ice thrown off during operation, GE Energy always recommends the use of an ice detector.

The ice detector is installed on the nacelle. It is possible to detect the build-up of a small amount of ice by means of the ice detector. If this is the case, the ice detector sends a signal to the turbine controller. The turbine controller disconnects the wind turbine generator system from the grid and the rotor is brought to a standstill or rotates at a very low speed. A message about the icy condition is displayed on the monitor in the

turbine, In addition, a message is sent to the service station and the operator via modem. The turbine does not restart until the detector is free of ice or the operator has satisfied himself of the ice-free condition of the rotor blades, has acknowledged the ice alarm message and restarts the plant.

However, ice may form on the rotor blades considerably more quickly than on the ice sensor on the nacelle. As a result, there is a residual risk for the reliable detection of ice build-up on the rotor blades.

The detector on the nacelle must be set relatively sensitively, in order to ensure that the time from when ice starts to build up on the rotor blades until the detector sends a message about the build-up of ice is as short as possible. As a consequence, a certain number of spurious trippings cannot be excluded. Loss of energy yield may occur as a result of the spurious trippings.

If an ice detector is not used, it is advisable to cordon off an area around the wind turbine generator system with the radius R* during freezing weather conditions, in order to ensure that individuals are not endangered by pieces of ice thrown off during operation (cf. also Section 11.1).

*R = 1.5 x (hub height [m] + rotor diameter [m]) (Recommendation of the German Wind Energy Institute DEWI 11/1999)

8.4.2 Icy Condition of the Access Route During the winter months, access to the plants may be very slippery due to ice or hard-packed snow. There is an increased danger of slipping. cf. Section 11.1 on approaching and entering WTGs which may be frosted.

8.4.3 Icy Condition of the Tread of the Steps outside the Nacelle In the winter months, the tread of the steps outside the nacelle can be icy as a result of ice and hard-packed snow.

8.5 Exceptional Dangers – Earthquakes

In the case of an earthquake, the operator must inspect the WTG for damage. The following procedure is recommended:

• Determination of the acceleration values in the tower top which arose during the earthquake (PCH BOX). • Contact GE Energy, in order to agree on the further procedure and possible inspection schedules.

Tools and materials left in the control cabinets lead to unsafe Danger! working conditions for the service technicians when the plant is put to operation again.

Danger from electrical current! All axis and battery cabinet doors must be securely latched in place before the system is reenergized to avoid exposure to the Danger! potentially hazardous transient voltages that are present during start-up.

10 Conduct in Emergency Situations

10.1 Conduct in Case of Fire

In principle the WTGS consists of fire-resistant materials. However

Fire, open flames and smoking are prohibited!

If a fire does occur, however, call the fire department immediately!

State the following information:

• Name of the person calling • What is on fire • Where the fire is located (seat of the fire / location of the plant) (You will find the site coordinates on the nameplate) • Wind direction and wind strength

Note the following information in the case of fire:

• Saving lives has priority over fire-fighting • Alarm all personnel who are in the WTG • Use the escape routes described in Chapter 10.2 – ensure that you are familiar with the various escape routes. • Do not use the service lift. • Burning debris can be expected to fall down if there is a fire in the nacelle or the upper part of the tower. • If the wind turbine generator system is still in operation, it must be stopped and a large area around the plant cordoned off. • Close the door of the plant.

10.1.1 Fire-Fighting Fire-fighting may only be carried out by immediately fighting an initial fire using the fire extinguishers that may be available in the plant. The locations of the firefighting equipment (if available) in the tower and the nacelle are marked.

If the initial fire cannot be extinguished within a short time, abandon any further attempts to extinguish the fire and call the fire department immediately.

In addition to the direct danger from the fire, a combustion toxicity hazard and the danger of asphyxia could also arise. As a result, move in a crouched position if smoke develops and also crouch down when attempting to extinguish the fire.

Attempts to extinguish a fire may lead to very serious burns! Do not make any attempts to extinguish the fire beyond the initial attempt. Due to confined space limitations, since the required Danger! minimum distance cannot be maintained while attempting to extinguish the fire.

10.1.2 Fire in the Tower - Person in the Nacelle • Leave the WTG immediately via the second escape route (cf. Chapter 10.2). • Abseiling device in the nacelle - emergency exit using the abseiling device

10.1.3 Fire in the Nacelle - Person in the Nacelle • Attempt to extinguish the fire.

If unsuccessful:

• Leave the danger area immediately via the first escape route (cf. Chapter 10.2). • Do not use the service lift. • Do not use the abseiling device.

10.1.4 Fire in the Transformer

Do not make any attempts to extinguish the fire – High voltage! Conventional fire extinguishers are not suitable. Danger!

• Leave the WTG immediately.

In the case of transformers in the tower:

• Leave the WTG via the second escape route

In the case of transformers in the transformer station:

• Leave the WTG via the first escape route

Fire-fighting may only be carried out by trained personnel.

10.2 Escape Routes

Keep escape routes clear! The escape and rescue routes must be free of obstructions (tools, equipment, rubbish, etc.), in order to ensure that the turbine can be Attention! evacuated as quickly as possible in an emergency.

10.2.1 First Escape Route In case of fire, leave the plant immediately. The first escape route from the nacelle is down the ladder in the tower. The descent is facilitated and made safer by resting platforms every 6 m. Do not use the hoisting passenger suspension device.

10.2.2 Second Escape Route If the descent through the tower is no longer possible, use the second escape route. (Abseiling with the abseiling device). This either leads over the roof of the nacelle (hooking point on roof rail) or through the emergency descent hatch which may be present (hooking point directly beside the winch in the nacelle, which is also present in this case).

Correct use of the abseiling device:

• Make sure your safety harness if on correctly. • Attach lanyard to approved tie-off point or nacelle rail.

Use of the abseiling device! Your life could depend on the correct use of the abseiling device. The abseiling device can also be used by two people to abseil. Danger! Read the instructions before beginning the abseiling operation!

10.3 Information for Rescue and Emergency Personnel

The rescue services and the emergency personnel must be equipped with their own personal protective equipment (safety harness, etc.). The rescue/emergency personnel must bring with them all the equipment required for rescuing personnel from the hub, nacelle or tower.

The information stated in this safety manual must also be read by the rescue / emergency personnel.

10.4 Oil Spill – Immediate Measures

The objective of the immediate measures is to prevent or at least to contain a further uncontrolled escape of water-endangering substances and keep the areas of threatened or contaminated soil as small as possible, under consideration of safety engineering requirements.

Inform yourself about the oils used beforehand. The safety data sheets provide details of Water Hazard Classes and suitable measures for combating oil pollution.

Measures 1. Decide and act quickly, so that the amount of oil reaching the environment is kept as small as possible. 2. Prevent further discharge (closure of valves, temporary sealing of cracks and holes, e.g. by means of sealing rags, sealing bags, sealing wedges, collection in containers, pumping out, transfer, etc.) 3. Bind the discharged oil – use approved oil binding agents and oil binder mats if the oil could not be pumped out or skimmed off in time. The damage can be limited by means of collecting containers, rolled foils and a shovel. 4. Prevent the oil from getting into the soil or bodies of water. 5. Remove contaminated soil. 6. Take the contaminated oil-absorbing materials to a local specialist waste disposal company for material recovery/conversion to energy or disposal. The national regulations are to be complied with.

11 Remaining in and on the Wind Turbine Generator System

Fire Hazard! The storage of combustible or highly inflammable materials in the wind turbine generator system is not allowed. Attention!

Personnel may not remain inside the WTG, and maintenance or repair work may not be carried out in or on the WTG under power supply. There is a danger of accident and a danger to life and limb. In order to prevent accidents, the following actions are to be carried out in the following order before and on entering the wind turbine generator system:

1. Shut down the WTG and secure against an unauthorized return to service 2. Put on the personal protective equipment 3. Disable the power supply for the work to be carried out – carry out corresponding Lockout/Tagout instructions (cf. Chapter 13)

Staying in the WTGS while it is in operation is unavoidable in the case of certain maintenance and repair work. In such cases a risk assessment should be developed for the task. Particular care is called for and hearing protection must be worn.

In addition, the following safety regulations are to be complied with without fail:

• As a general principle, no person may stay in the WTG during a gale or a thunderstorm! If a thunderstorm comes up, the WTG must be left immediately. • The WTG may only be entered in the company of a second person who can provide assistance or call for help in the case of an accident. • The entrance door to the tower must be kept closed or if it is kept open, it must be properly secured to prevent it from flying open and getting warped. • Long open hair, loose clothing (e.g. flapping coats, tops with wide sleeves or trousers with wide legs) and scarves, ribbons, headscarves or jewelry may not be worn in the WTG! There is a fundamental danger of injury as a result of getting caught, trapped or drawn in by rotating elements! Clothing must always be tailored to suit the respective work and the weather conditions. • Switch-on and shut-down procedures in accordance with the operating manual are to be complied with for all work which concerns the operation and adjustment of the WTG and its safety equipment. • If any changes in the operating characteristics which are relevant to safety or any faults arise in the WTG, it must be shut down immediately and the event reported to GE Energy or the customer (if a maintenance contract has not been concluded with GE Energy).

11.1 Approaching and Entering Frosted Wind Turbine Generator Systems

Before parking near the turbine, stop approx. 350 m from the turbine and check the rotor blades for ice by means of binoculars and the sound of the rotation of the blades. If the turbine is running and ice is present on the rotor blades, call for a remote stop. Once the blades have come to a complete standstill, verify that none of the blades is located over the entrance door of the turbine. If this is the case, call for a remote traverse of the yaw drive in any direction, so that the rotor is positioned on the side of the turbine opposing the door. As soon as the rotor is correctly positioned, call for a remote stop of the yaw drive and ask for confirmation of this operation.

Once the above conditions have been complied with, park your vehicle at a safe distance from the WTGS (at least 100 m). Watch out for falling ice as you approach the tower. If the wind is blowing against the opposite side of the door (or into the rotor at this point), you must proceed with extreme caution, since falling ice could be blown in your direction.

Danger of slipping as a result of icy conditions! There is danger of slipping as a result of the frozen ground and ice on the foundation and the stairs.

Warning! Sprinkle de-icing salt or sand over the foundation. Use the handrail when going up the stairs.

Leave the immediate vicinity of the WTG after completing your work. Watch out for falling ice. Get into your vehicle. Do not call for a remote re-activation of the yaw drive and restart of the turbine until you are approximately 350 m away from the WTG.

11.2 Shut-down of the Wind Turbine Generator System

Before starting any service work, the wind turbine generator system must be deactivated. Proceed as follows:

1. Contact any remote monitoring groups that are supervising the site (before entering the wind turbine) 2. Contact any site operators or maintenance people (before entering the wind turbine) 3. Temporarily disconnect the Mark VIe controller from the site SCADA network: — Locate the SCADA network switch in the down tower assembly that houses the SCADA network switch — Disconnect the two fiber pairs (RX-TX and RX-TX) from the switch, taking the turbine off the site network 4. Press the "Stop-Reset" button to shut-down the plant manually. 5. Set the key-operated switch to "Repair".

Follow lock-out-tag-out procedures to de-energize, lock-out and tag-out equipment to ensure that unit equipment is always put in a safe condition. Wind conditions must be continuously monitored manually if LOTO procedures used mean that the unit is not

capable of moving to minimum load condition.

Danger of accident! The WTG must remain shut down as long as personnel are in the plant. Before it is returned to service by authorized personnel, check without fail that nobody is in the plant. Otherwise there is the danger of an accident!

11.3 Climbing the Tower

• Only persons who are physically fit, are wearing appropriate PPE and are capable of coping with the ascent may climb the WTGS. • The WTGS must be shut down and secured against unauthorized start-up before the tower is ascended. The WTGS must remain shut down as long as anybody is climbing the tower or is on the tower platform. • The entrance door to the tower must be kept locked, in order to inhibit access to unauthorized persons. • In order to avoid accidents caused by falling objects, nobody may stand under the ladder while somebody is ascending the tower. Even a small screwdriver can cause very serious injuries if it drops from a great height.

Danger through falling objects! Falling objects can cause very serious injuries irrespective of their size and weight! Never stay in the vicinity of the ladder while somebody is ascending or descending. The ladder may only be used by one

person at a time. Only after this person has reached an Danger! intermediate platform and has closed the tower hatch or has reached the ground in the tower base and stepped back from the ladder may the next person approach the ladder. Tools and equipment must be secured while climbing.

• Fall protection PPE must always be put on correctly before ascending the tower. • Always check the safety harness and the entire safety equipment prior to use. Damaged PPE may never be used. • Safety boots and a hardhat must be worn when ascending the tower. Gloves must be worn while climbing. • The maximum possible fall path must be kept to a minimum by means of rope-shortening devices or similar. • Only use marked hooking points with an adequate load-bearing capacity. • The tower may only be ascended by means of the ladder installed inside the tower or (if the person is properly trained) the hoisting passenger suspension devices/service platform which may be installed. (Follow the operating instructions of the manufacturer).

• The rail or cable grab must run freely in the rail while ascending and descending the tower. Never touch the travelling safety hook, otherwise there is a danger of injury! • Both hands must be kept free during the ascent or descent. Tools, lubricants and other material may only be transported in a suitable bag. Permanent "3-point contact" with the ladder is only guaranteed by this means. • Greater care needs to be exercised when climbing the ladder experiencing wet conditions or if the tower is covered in ice. • Only unhook the lanyard after you have reached the tower platform and the access hatch has been closed. • Ensure that you are always protected by at least one lanyard with a fall arrest block. • The rest platforms in the tower are fitted with hatches that must be kept closed at all times. The platform hatches must therefore be opened on reaching a platform and closed again immediately after crossing to the next section of the tower. Tie off to anchor points while on platforms when hatches are open.

11.4 Deactivation of the Yaw Drive

Yaw stop switches are located in the tower base, below the nacelle and on the top box in the nacelle. The yaw drive and the automatic nacelle adjustment are disabled in the "Off" switch position, so that the nacelle is technically prevented from moving if there is a change in wind direction.

11.5 Entering the Nacelle

The yaw stop switch on the uppermost tower platform must be placed in the "Off" position before crossing from the tower to the nacelle. The yaw drive and the automatic nacelle adjustment are thereby disabled.

Depending on the position of the nacelle, the available simple ladder is hooked into one of the holders to prevent the ladder from slipping. Some of the WTGs are provided with a permanently installed extension ladder.

Hooking points are available in the vicinity of every platform.

11.6 Walking on the Roof of the Nacelle/Entering the Rotor Hub

The roof of the nacelle may only be accessed for entering the rotor hub and for carrying out work on the wind vane, the anemometer and the obstruction light.

Only trained or instructed staff are permitted to enter the hub or walk on the roof of the nacelle. The rotor hub may only be entered at maximum wind speeds up to 15 m/s. The rotor lock on the high-speed shaft (brake disk on the coupling) must be engaged before the rotor hub is entered.

1. Place the yaw stop switch on the top box in the "Off" position. 2. Turn the rotor to the "Y" position, so that the rotor hub can be entered. 3. Engage the rotor lock on the high-speed shaft. 4. Turn the rotor blades to the 85° feathering position.

Fig. 15: Rotor in the "Y" position

Life-threatening hazard through sudden start-up of the rotor if the rotor lock (brake disk on the coupling) on the high-speed shaft has not been engaged! Always engage the rotor lock on the high-speed shaft before

entering the rotor hub. Danger! FOLLOW THE RESPECTIVE LOCKOUT/TAGOUT INSTRUCTIONS! (cf. Chapter 13)

Maintenance work inside the hub may only be carried out at maximum wind speeds up to 15 m/s!

Always engage the rotor lock on the high-speed shaft. Use of the Warning! rotor lock on the low-speed shaft or only the brake on the high- speed shaft for this purpose is prohibited.

Falling Hazard! Warning: strong wind currents! Before climbing out of the nacelle enclosure through the roof hatch above the gearbox, the lanyard must be hooked on to the rail on the nacelle, then transfer to the spinner if transitioning to the hub. The roof rail is to be selected as a hooking point for all other work on the roof of the nacelle. Follow the hub access and rotor Lock Out/Tag Out (LOTO) procedures, in addition to proper JSA/EHS Danger! procedures.

6. Switch the pitch controller on the control cabinet to "Manual".

Fig. 17: Pitch controller

Walking on the Roof with Ice and Snow If you have to walk on the roof of the nacelle or climb into the hub, first of all ensure that the rotor blades are in the Y position before you open the hatch. Otherwise there is danger of injury from falling pieces of ice.

Danger of Slipping and Falling Hazard as a result of icy conditions! There is a high risk of slipping and falling if the roof of the nacelle and the spinner are covered by snow and ice. Completely remove any snow and ice from the roof before walking on it. Sprinkle sand on the cleared areas Danger! Do not walk on the roof/spinner if the snow and ice cannot be removed completely and the danger of slipping cannot be excluded. Proper JSA/EHS procedures should be followed at all times.

11.7 Activation of the Wind Turbine Generator System

Danger of accident! The WTG must remain shut down as long as personnel are in the turbine. Before it is returned to service by authorized personnel, check without fail that nobody is in the turbine. Otherwise the danger of an accident arises!

Proceed as follows to return the WTG to service:

1. Make an entry in the service life card of the WTG 2. Connect the Mark VIe controller to the site SCADA network: • Locate the SCADA network switch in the down tower assembly that houses the SCADA network switch • Reconnect the two fiber pairs (RX-TX and RX-TX) from the switch, putting the turbine on the site network 3. Set the key-operated switch to "Operation". 4. Check the alarm message panel in home web page for error messages 5. Press the "Stop-Reset" button and then the "Start" button. 6. Inform the remote monitoring division that wind turbine is back in operation 7. Inform the operator / customer that wind turbine is back in operation

12 Information on Maintenance and Troubleshooting

13 Power Disconnection and Isolation Procedures (Lock-out/Tag-out Instructions)

Pursuant to EN 50308 and OSHA standard 29 CFR 1910.147, wind turbine generator systems must be equipped with devices to disconnect and isolate them from all their energy sources during inspection and maintenance work.

These disconnecting/energy-isolating devices are prescribed for all mechanical, electrical and hydraulic energy sources.

GE Energy advises the plant operator/owner to develop specific procedures for the power disconnection and isolation of every individual subsystem.

Local and national regulations must be taken into account when developing workplace-specific Lockout/Tagout instructions.

The disconnection/isolation points are marked in the plant-specific circuit diagrams and hydraulic schematics supplied with the respective WTG.

Procedures for the Lock-out/Tag-out of power disconnection and isolation devices must consider the following aspects:

13.1 Identification of Installations, Processes, Circuits

(Individual mechanical, electrical or hydraulic subsystems)

13.2 Preparation for Shutdown / Notification of Affected Employees

• All personnel who may be affected must be notified before Lock-out/Tag-out devices are installed and after they have been removed. In addition to this procedure, authorized employees must be aware of any additional safety requirements prescribed for working on this type of equipment. • Affected employees who work on or near an installation which is about to be disconnected and on which Lock-out/Tag-out devices are to be mounted must be notified thereof.

13.3 Identification of Energy Sources and Strengths

13.4 Deactivation of Energy Sources and the Mounting of Energy Control Devices

• The power disconnection and isolation devices (e.g. disconnecting switches or load interrupter switches, valves etc.) must be positioned in such a way that they interrupt the energy flow to installations, processes or circuits. The authorized employees are obliged to mount and secure Lock-out/Tag-out devices to these. They must hereby ensure that the power disconnection and isolation devices are "locked out" until further notice and remain in their safety or "Off" position.

13.5 Control of Stored Energy

Residual risks from stored energy!

PLEASE OBSERVE THE RESPECTIVE LOCKOUT / TAGOUT Attention! INSTRUCTIONS!

• The authorized employee must ensure that all potentially hazardous energy in any form (stored, residual, chemical or potential energy) is relieved, dissipated, contained, discharged or otherwise controlled. Additional measures may be necessary to prevent the re-accumulation or re-storage of energy, in order to protect personnel. Stored energy can form e.g. in batteries, capacitors, through gravity or in chemical lines.

13.6 Verification of Isolation

• The authorized employee must verify that the isolation and de-energization of the respective installation, process or circuit has actually been carried out before maintenance work may be started. The check must confirm that the installation, process or circuit has achieved a "zero" energy state. (Test equipment, circuit activation attempts, measuring devices, visual inspections, etc. can be used to verify the zero energy state.)

13.7 Reconnection of the Installation to the Supply

The authorized employee must carry out the following measures before returning the installation to service:

• Inspection of the work area to ensure that all items which are not required for the operation of the installation have been removed and that all the guards have been replaced, that the machine/installation, process or circuit is operational and that all personnel are in a safe location. • Removal of all locks, tags and other Lock-out/Tag-out devices from all power disconnection and isolation devices by the authorized employee who previously attached these LOTO devices. • Notification of affected personnel that the energy supply is about to be restored to the machine/installation, process or circuit. • Visual inspection and/or cycle test to verify that the service or maintenance work has been successfully completed. Provided that the work has been completed, the machine/installation, process or circuit may be returned to service. Otherwise, the requisite procedural steps must be repeated. • Correct sequential run-up of the installation, process or circuit.

WTG operators must ensure that suitable disconnection regulations are available for their plants and construction sites and those they are implemented. GE Energy has developed installation-specific Lock-out/Tag-out procedures for the activities listed below. This list does not claim to be complete, however. It may be advisable to develop additional procedures as a result of changes to installations or to comply with construction site-specific disconnection regulations.

Attention: Kent N. Truckor Manager, Business Development

Subject: Sound Model for Additional Updated Turbine Layout (11 March 2016) Proposed Hardin Wind Farm Hardin County, Ohio Acentech Project No. 627334

References: Your February and March 2016 emails to me Acentech Project Nos. 620456 & 624960

Dear Mr. Truckor:

At your request, Acentech developed updated sound models (March 2016) of the proposed nominal 270 MW Hardin Wind Farm. The current plan for this wind farm consists of 118 wind turbine generators (WTGs), which may be either the GE Model 2.3-116 or the GE Model 2.3-116 LNTE version. The project area is mostly agricultural land that includes about 1311 residences located over the site and within one mile of the site boundary. This turbine layout supersedes earlier layouts that were under consideration and that were modeled in 2009 and 2014. The results of our updated sound model for the currently proposed Hardin Wind farm are presented in this letter report and additional files.

We updated our Cadna/A computer sound model for the Hardin Wind project and estimated the sound contributions of the proposed 118 turbines. The source levels were based on turbine vendor data that you provided us. Our studies assumed all wind turbines were operating at the maximum sound levels provided by the vendor. The model included all residential receptor locations that were provided by Invenergy and the results show all residences within one-mile of the 118 proposed wind turbine project area.

Sound Model Description The estimated sound levels and contours, which apply to both daytime and nighttime hours for the operating phase, were developed with the computer noise modeling program, Cadna/A. This commercial software program, which was developed by DataKustik GmbH (www.datakustik.de), is widely-accepted by the international acoustics community for the calculation of community sound levels due to industrial sources. The calculations are performed for industrial sources according to the following international standards:

acoustics  av/it/security  vibration Kent N. Truckor Hardin Wind, Hardin County, OH 17 March 2016 Page 2 of 19

• ISO 9613-1: Acoustics - Attenuation of sound during propagation outdoors, Part 1: Calculation of the absorption of sound by the atmosphere, and

• ISO 9613-2: Acoustics - Attenuation of sound during propagation outdoors, Part 2: General method of calculation.

Inputs to the program include: source locations and associated sound power emissions, receptor locations, land topography, and meteorological conditions. The calculations account for spreading losses, atmospheric attenuation, ground effects, terrain and other barrier shielding, and reflections for the sound between each source and each receptor. For this study, the sound propagation routines and barrier calculations in the Cadna/A model are based on octave band sound pressure levels and on downwind conditions with a moderate temperature inversion. The following describes significant parameters used in the sound model at your request:

• Turbine, project boundary, 1-mile boundary, and residence locations – the shape files with these data were owner-provided.

• Land elevation contours – the shape files with these data were owner-provided.

• Wind turbine data – Model GE 2.3-116 and Model GE 2.3-116 LNTE version with respective maximum A-weighted sound power levels (LwA) of 107.5 and 106 dBA and hub height at 80 meters (turbine input as point source at 80m height above local terrain). Spectral values based on published vendor data.

• Meteorological conditions are 10°C (50°F) and 70%RH, moderate inversion, and all receptors downwind from turbines.

• Ground conditions – moderate soft ground with parameter G = 0.5 and spectral calculations for all sources.

• Receptor heights – 1.5m above local ground elevation.

Sound Model Results Figures 1 and 2 present the proposed wind farm layout with the 118 GE 2.3-116/GE 2.3-116 LNTE turbines, project boundary, one-mile boundary from the project, the residences within the one-mile boundary, and the estimated sound level contours in 5 dBA increments. The computer shape files of the sound level contours (1 dBA increments) and an Excel file with the estimated facility sound level at each of the 1311 residences within one-mile boundary of the project site are provided in a separate transmittal. The estimates are based on the greatest sound output condition for each turbine model (e.g., LwA=107.5 dBA and 106 dBA at ≥9.8 m/s wind speed at the hub height elevation). Table 1 lists the overall turbine facility sound levels (dBA) for the 390 residences within the one-mile boundary of the project with GE 2.3- 116 turbines installed that have estimated levels at or above 43 dBA. The estimated sound levels produced only by the wind farm range at the residences within the one-mile boundary of the project from less than 10 dBA to about 51 dBA for the GE 2.3-116 turbine layout and 49 dBA for the GE 2.3-116 LNTE turbine layout. Note that these results represent typical upper levels that apply to both daytime and nighttime hours; levels up to about 4 dB greater than these should be expected at times under certain meteorological and operating conditions.

Although the turbines will be heard at community locations at times during turbine operation and quieter ambient sound levels, the WTG sound emissions will be less under conditions of reduced wind speeds, including the times below the minimum cut-off wind speed when the turbine does not operate. For example, the estimated sound levels will be less than the displayed values by about 3 dBA for hub-height wind speeds of 8 m/s and about 6 dBA less for 7 m/s.

EXEXCUTIVE SUMMARY

A shadow flicker impact analysis was originally conducted for the Hardin Wind Farm Project (Project) in July 2009. That analysis was based on the original 212 wind turbine layout project design. The July 2009 analysis was updated in December of 2009 to evaluate the revised Project based on a layout design comprising 203 wind turbines. The analysis was again updated to evaluate the Phase 1a project layout of 132 wind turbines in June of 2011. The analysis was further updated in June 2014 to evaluate the revised project layout of 121 wind turbines and a new wind turbine model (GE 2.5 – 120). The analysis presented here is based on an updated layout of 118 turbine locations and new turbine model (GE 2.3-116) as of March 2016.

The calculated sunshine probability data is presented in Section 2. The WindPro prediction results are presented in Section 3.

1 Hardin Wind Farm – Shadow Flicker Analysis

1.0 BACKGROUND

A wind turbine’s moving blades can cast a moving shadow on locations within a certain distance of a turbine. If the shadows pass over a window of a home or public gathering place, they can create alternating periods of low and high light, a temporary phenomena referred to as “shadow flicker”. The maximum length of the shadows depends on the time of year and day (which determines the sun’s azimuth and altitude angles) and the wind turbine’s physical characteristics (height, rotor diameter, blade width, and orientation of the rotor blades). Shadows are longest during low angle sunlight conditions, typical during sunrise and sunset times of the day. However, when the sun angle gets very low (less than 3 degrees), the light has to pass through more atmosphere and becomes too diffuse to form a coherent shadow. Shadow flicker will not occur when the sun is obscured by clouds or fog, at night, or when the source turbine(s) are not operating.

Shadow flicker intensity is defined as the difference in brightness at a given location in the presence and absence of a shadow. Shadow flicker intensity diminishes with greater receptor-to- turbine separation distance. Shadow flicker intensity for receptor-to-turbine distances beyond 1,500 meters is very low and generally considered imperceptible. Shadow flicker intensity for receptor-to-turbine distances between 1,000 and 2,000 meters (between 3,281 and 6,562 feet) is also low and generally considered barely noticeable. At this distance shadow flicker intensity would only tend to be noticed under conditions that would enhance the intensity difference, such as observing from a dark room with a single window directly facing the turbine casting the shadow. At distances less than 1,000 meters (3,281 feet), shadow flicker may be more noticeable. In general, the largest number of potential shadow hours, along with greatest potential shadow flicker intensity, occurs nearest the wind turbines.

Shadow flicker intensity is also affected by the relative percentage of the solar disk which is masked (covered) by the turbine rotor. WindPro calculations also implements German guidance which indicates that when less than 20% of the solar disk is masked, the shadow will be too diffuse to cause a significant impact.

Shadow flicker frequency is related to the wind turbine’s rotor blade speed and the number of blades on the rotor. From a health standpoint, such low frequencies are harmless. For comparison, strobe lights used in discotheques have frequencies which range from about 3 Hertz (Hz) to 10 Hz (1 Hz = 1 flash per second). As a result, public concerns that flickering light from wind turbines can have negative health effects, such as triggering seizures in people with epilepsy are unfounded. The Epilepsy Action (working name for the British Epilepsy Foundation), states that there is no evidence that wind turbines can cause seizures. However, they recommend that wind turbine flicker frequency be limited to 3 Hz (http://www.epilepsy.org.uk/info/photo_other.html). Since the proposed Project’s wind turbine blade pass frequency is approximately 0.79 Hz (less than 1 alternation per second), no negative health effects to individuals with photosensitive epilepsy are anticipated.

2 Hardin Wind Farm – Shadow Flicker Analysis

2.0 WINDPRO SHADOW FLICKER ANALYSIS

Tetra Tech estimated potential shadow flicker impacts from the Hardin Wind Farm using the WindPro software package and the following information provided by Hardin Wind Energy LLC (HWE):

• 118 turbines located at the coordinates listed in Attachment B and as shown on Figure 1.

• The wind turbines are assumed to have the dimensions of the GE Wind Energy GE 2.3- 116, a 3-blade 116-meter-diameter rotor wind turbine with a hub height of 80 meters. The GE 2.3-116 has a nominal rotor speed of 15.7 rpm which translates to a blade pass frequency of 0.79 Hz (less than 1 alternation per second).

• 532 receptors (residences) are located at the coordinates listed in Attachment A and as shown on Figure 1.

The analysis makes the following assumptions:

• The elevations of the wind turbines and receptors are determined using USGS digital elevation model (DEM) data.

• The position of the sun and the incident sunlight relative to the wind turbine and receptors on a minute by minute basis over the course of a year.

• Annual average sunshine rates for the area are based on an average of National Climatic Data Center (NCDC) data for stations located in Columbus and Toledo, Ohio and are assumed to be:

Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 38% 45% 46% 51% 56% 58% 60% 58% 57% 53% 34% 29%

Values from Columbus and Toledo were used because NCDC sunshine data is not available for Kenton, Ohio1, but it is available for measurement stations in both Columbus and Toledo, Ohio. The sunshine probability data from these stations were averaged together to calculate sunshine probability data assumed to be representative of the of the project area. Tetra Tech considers this to be a conservative assumption that underestimates cloud cover since it evenly averages data from both sites, even though the project is slightly closer to Columbus and Columbus has a higher cloud cover rate.

• Wind turbine operating hours and orientations are based on approximately 1 year of data measured on-site from 5/21/08 to 6/22/09. Based on this data, wind turbine orientations are assumed to be as follows:

N NNE ENE E ESE SSE S SSW WSW W WNW NNW 4.1% 5.4% 7.7% 6.7% 4.9% 6.3% 8.7% 15.1% 13.1% 13.1% 9.1% 5.8%

3 Hardin Wind Farm – Shadow Flicker Analysis

• Receptor viewpoint (i.e., house windows) is assumed to always be directly facing turbine to sun line of sight (“greenhouse mode”).

• Every receptor is modelled as a 1 m2 area (approximate size of a typical window), 1 meter (3.28 feet) aboveground level. Approximate eye level is set at 1.5 meters (4.9 feet).

• Screening from trees, shrubs, barns, or other obstacles was conservatively not assumed to block shadows. In reality, such factors can block shadows from falling on to windows of receptors.

WindPro incorporates terrain elevation contour information and the analysis accounts for terrain elevation differences. WindPro calculates the sun’s path with respect to each turbine location to determine the shadow paths for every minute in a full year. Sun angles less than 3 degrees above the horizon were excluded, for the reasons identified in Section 1. WindPro calculates shadow flicker for conditions when at least 20% of the sun disc is covered by the turbine blades. When less than 20% of the solar disk is masked by the blades, the shadow will be too diffuse to cause a coherent shadow

HWE identified 532 receptors within 1,000 meters of a proposed wind turbine. Only these receptors were analyzed in the WindPro analysis. Figure 1 shows the locations of the modelled receptors and turbines.

6 Hardin Wind Farm – Shadow Flicker Analysis

4.0 CONCLUSION

This report represents an update to the shadow flicker analysis conducted and submitted in support of the Hardin Wind Energy Amendment 1 application to the Ohio Power Siting Board in June 2011. This analysis was completed utilizing the same modeling assumptions that were utilized in the June 2011 shadow flicker analysis, with the exception of the GE 2.3-116 turbine model characteristics. Shadow flicker impacts within the area of study are expected to be minor. The analysis assumes that the houses all have a direct in line view of the incoming shadow flicker sunlight and does not account for all the trees or other obstructions which may block sunlight. In reality, the windows of many houses will not face the sun directly for the key shadow flicker impact times. For these reasons, shadow flicker impacts are expected to be less than estimated with this conservative analysis, and shadow flicker is not expected to be a significant environmental impact.
