Issue Date 11.12.2014 NW20.40.09 Amendment No.05 Page 4 of 37 Orion NZ Ltd. Contingency Plan Security of Supply Participant Rolling Outage Plan

1. INTRODUCTION This plan was written to comply with the Electricity Industry Participation Code 2010, Part 9 Security of Supply. The procedures outlined are in response to major generation shortages and/or significant transmission constraints. Typical scenarios include unusually low inflows into hydro- generation facilities, loss of multiple thermal generating stations or multiple transmission failures. How an event is declared and how the System Operator should communicate its requests are detailed. The main energy saving measure listed is rolling outages and how these are structured and implemented is discussed.

2. PURPOSE Under the Code, participant rolling outage plans (PROP) are required to specify the actions that would be taken to; a) be consistent with the system operator rolling outage plan; and b) comply with the requirements specified in the notice sent under clause 9.6(2)(a) of the code; and c) specify the actions that Orion will take to achieve, or contribute to achieving, reductions in the consumption of electricity (including any target level of reduction of consumption of electricity in accordance with criteria, methodologies, and principles specified on the system operator rolling outage plan) to comply with a direction from the system operator. Reducing demand by disconnecting supply to customers would be a last resort after all other forms of savings including voluntary savings had been exhausted. Orion will always endeavour to keep supply on to customers.

4. BACKGROUND

4.1 ELECTRICITY AUTHORITY The Authority is an independent Crown entity responsible for the efficient operation of the electricity market.

Core functions of the Authority are to:

• make and administer the Electricity Industry Participation Code 2010 (Code) governing the New Zealand electricity market; • monitor and enforce compliance with the Code, various regulations, and the Act;

4.2 TRANSPOWER Transpower is a State Owned Enterprise, tasked with owning and operating New Zealand’s National Grid - the network of high voltage transmission lines and substations that connect areas of generation with town and cities across the country. As System Operator, Transpower manages the real-time operation of New Zealand's electricity transmission system. It keeps the right amount of energy flowing to match generated supply with demand.

4.3 ORION Orion is the electricity network company that owns and maintains the electricity lines and cables that deliver power to the and Central Canterbury region between the Waimakariri and Rakaia rivers.

5. RANGE OF EVENTS Events that could lead the System Operator to make a Supply Shortage Declaration can in general terms be categorized as; • Developing (Category A) Event – Events that evolve over time, for example low hydro lake or fuel levels. • Immediate (Category B) Events – Events that occur with little or no warning, usually as a result of a transmission line or major generation failure.

8. ACTIONS FOR IMMEDIATE (CATEGORY B) EVENTS

8.1 SYSTEM STABILITY Transpower, as the System Operator, is required to keep enough reserve generation to cover the risk of the largest connected generator tripping. They are also required to keep the system frequency at 50Hz. If a large generator trips, it may cause a reduction in frequency which if not rectified can result in other generators tripping and could lead to cascade failure of the transmission system. As reserve generation cannot immediately pick up the load of a disconnected generator, an immediate load reduction is required until additional generation can pick up load. Automatic load shedding groups reduce load in stages until the frequency stabilises. To recover from category B events electricity consumption can be reduced by;

8.2 RESERVE MARKET Generators and load users with interruptible load such as distribution networks may offer in reserve capacity to cover the risk of the largest generating unit or a critical transmission line tripping. The ability to do this is affected by the numbers of frequency capable relays installed and the likely revenue stream from the market less the compliance costs of participating in the reserve market. Orion does not presently participate in this market.

8.2.1 Disconnecting Customers

8.2.1.1 Automatic Under Frequency Load Shedding (AUFLS) If the load shed by the Reserve Market tripping is insufficient to stabilise the network, further automatic load reduction is required. In the South Island, Transpower is responsible for ensuring each distribution network company must (unless exempted) have available at all times two blocks of load each of 16% of its total load to be shed by automatic under frequency relays.

8.2.1.2 AUFLS Zone 1 If system frequency fails to recover after Reserve Market load shed, AUFLS Zone 1 shedding will occur by disconnecting customers supply. In the Orion Network the tripping relays are either owned by Transpower or Orion and whole zone substations are tripped. AUFLS feeders are listed in NW20.40.05.

8.2.1.3 AUFLS Zone 2 If zone 1 tripping fails to restore frequency, the next stage, zone 2 activates. This will disconnect a further 16% of Orion’s Network.

8.2.1.4 Manual Shedding If AUFLS Zone 1 and Zone 2 tripping fails to stabilise frequency the System Operator will shed more load. Emergency load shedding feeders are listed in NW20.40.05. Once the frequency has stabilised the System Operator will advise the Orion Control Centre when load can be restored.

8.3 SUPPLY RESTORATION Disconnected load must be restored in conjunction with the System Operator. This is to prevent overloading the transmission grid and/or creating further instability.

Issue Date 11.12.2014 NW20.40.09 Amendment No.05 Page 8 of 37 Orion NZ Ltd. Contingency Plan Security of Supply Participant Rolling Outage Plan

8.4 TRANSMISSION GRID EMERGENCY The System Operator may request Orion to reduce load under a Grid Emergency Notice (GEN). Orion will shed all water heating load, the System Operator will be advised and if more shedding is required the System Operator will instruct the Grid Owner to disconnect load as per the emergency load shedding feeders listed in NW20.40.05. If a category B event is in place, the grid emergency will take precedence. If the System Operator declares a supply shortage during a Grid Emergency, then Orion will respond by implementing rolling outages as described in the following “Developing Events” section.

9. DEVELOPING (CATEGORY A) EVENTS If the System Operator requests a load reduction for a planned category A event, Orion must reduce supply to meet the System Operator targets. The targets are likely to be in the form of a weekly energy savings target that is reviewed each week. To reduce energy usage Orion would disconnect feeders or groups of feeders where they belong to a parallel or ring supply (rolling outage feeders) in a controlled manner to enable targets to be reached. Orion has a legal obligation to comply with the targets specified by the System Operator. Water heating load shedding is generally not an option for energy savings.

10. DECLARATION OF CATEGORY A EVENT The System Operator will endeavour to provide 9 days prior notice of the requirement for weekly energy savings and any increase in the weekly energy savings target. To declare a Category A event the System Operator will specify the energy savings target to be enforced for a specific region for a specified time-frame. The System Operator is responsible for general media advertising of the need to conserve electricity and the impending rolling outages when they are requested if a Public Conservation Campaign has been declared in accordance with the Code. If Orion plans to issue a public message related to rolling outages then this will be sent to the System Operator for review before being released. Any such communication will give a time for response from the System Operator, so as their feedback can be included before Orion issues the message to the public. On receipt of a declaration of a Category A event, Orion will update Appendix A with current load data.

11. CRITERIA FOR ROLLING OUTAGES To ensure public health and safety is preserved and costs to the economy are minimised the following table shows a desired criteria for selecting rolling outage feeders to be included in rolling outages.

Issue Date 11.12.2014 NW20.40.09 Amendment No.05 Page 9 of 37 Orion NZ Ltd. Contingency Plan Security of Supply Participant Rolling Outage Plan

11.1 TABLE 1: PRIORITY LOADS Priority Priority Concerns Maintain Supply to: Examples 1 Public health & Major hospitals, air CDHB hospitals safety traffic control centres, CHCH International Airport & emergency Urban police & fire stations operation centres Orion main building 2 Important public Energy control Major telecommunications connections services centres, Major malls & supermarkets communication Rural fire & police stations networks, water & Lyttelton Port sewage pumping, fuel Lyttelton Tunnel delivery systems, and Burnham military major port Major passenger transport connections CCC & SDC water pumping & waste water connections 3 Public health & Minor hospitals, Dental surgeries safety medical centres, Medical centres & doctors surgeries schools & street Colleges lighting Universities & polytechnics Prisons Major Hotels Non-CDHB hospitals & Rest homes All lighting category connections 4 Food production Dairy farms & milk All irrigation category connections production facilities All rural connections with a description that includes dairy, farm, irrigation, pig, poultry, cow or an ANZSIC code of A016 (Dairy farming) 5 Domestic production Commercial & ‘BUS’ connections not covered by industrial premises priority groups 1 to 4 Temporary supplies 6 Disruption to Residential premises All ‘RES’ connections consumers Wigram embedded network Belfast embedded network Churches Speed cameras Parks (mainly lighting & irrigation)

Rolling outage feeders will all contain a variety of customers. The priority for each rolling outage feeder will be based on the priority ratings assessed for the connections within each feeder, according to the following:

Priority Criteria 1 Any feeder that has one or more priority 1 connection 2 Any feeder that has three or more priority 2 connections or where the minimum of the simple and volume based weighted average priority < 2.5 3 Feeders where the minimum of the simple and volume based weighted average priority ≥ 2.5 and < 3.5 4 Feeders where the minimum of the simple and volume based weighted average priority ≥ 3.5 and < 4.5 or where the feeder includes large capacity connections 5 Feeders where the minimum of the simple and volume based weighted average priority ≥ 4.5 and < 5.5

Issue Date 11.12.2014 NW20.40.09 Amendment No.05 Page 10 of 37 Orion NZ Ltd. Contingency Plan Security of Supply Participant Rolling Outage Plan

6 Feeders where the minimum of the simple and volume based weighted average priority ≥ 5.5

Rolling outage plans will focus on lower priority feeders to the extent possible, and the higher priority feeders being selected only at the higher required savings levels. Rolling outage feeders with the same priority and in the same area (according to our grid exit areas) are grouped together into rolling outage groups. This level of grouping simplifies the planning, management and notification of rolling outages. The areas (GXPs for rolling outages) are:

Area GXP A Addington B Bromley C Hororata D Islington 33 E Islington 66 F Middleton

For example, group A6 refers to all rolling outage feeders in the Addington GXP area with a priority of 6.

11.2 VULNERABLE CUSTOMERS AND PRIORITY SITES

It is not possible for Orion to prevent rolling outages affecting individual vulnerable customers and priority sites. In addition to the prioritisation of rolling outage feeders, Orion will:

- Provide information in its public notices and website alerting vulnerable customers to the risks, and

- Request that retailers consider individually notifying their vulnerable customers.

12. AUFLS UNDER ROLLING OUTAGES The level of AUFLS during rolling outages needs to be maintained. Orion will either:

- exclude the current AUFLS feeders from its rolling outage plans, which means that supply to lower value loads may be maintained while higher value loads are cut, or

- Include AUFLS feeder shedding but limit the shedding to ensure that two AUFLS blocks of 16% are maintained. That is, if we shed 20% of our network load we would also shed up to 20% of the AUFLS load.

- Arm additional higher value load feeders to supplement the AUFLS load, and exclude these from its rolling outage plan. This document is drafted assuming that AUFLS feeders are excluded from shedding. However, where time permits, we would install and arm AUFLS relays on the higher value load feeders.

13. SHUTDOWN NOTIFICATION With the wide scale impact of rolling outages it is not feasible to use our standard planned outage notification process (mainly because retail and postal systems could not process the hundreds of thousands of outage notifications required). When implementing a rolling outage plan, Orion will notify the outages in a number of ways:

- Public notices - Orion will place public notice advertisements (see draft in Appendix C) providing a rolling outage timetable showing the times and areas affected by rolling outages. The advertisement will provide details of our website page for customers that wish to seek more information.

- Orion website - a dedicated website page will be set up which shows the rolling outage timetable, and allows customers to type in their ICP number to establish which rolling outage group they belong to.

- Retailer notification - Orion will provide the rolling outage timetable to all electricity retailers together with a schedule showing the rolling outage group for all ICP’s (it is not appropriate to filter the schedule for an individual retailer’s ICP’s as this places switching ICP’s at risk). Where possible, Orion will provide 7 days’ notice of all rolling outage plans, generally publishing and issuing notifications on a Monday to apply from the following Monday.

14. COMMUNICATION WITH SYSTEM OPERATOR All communications with the System Operator will be between Orion’s Control Centre and Transpower’s Regional Operating Centre (South) using Transpower’s TSX telephone or normal communication systems. Prior to notifying and implementing a rolling outage plan, Orion will consult with the System Operator Security Coordinator to establish a process for shedding and restoration, which may include a MW load cap to operate under during restoration phases. Unless agreed with the System Operator, load shedding and restoration shall be no more than 25MW per 5 minutes.

15. GRID EMERGENCY DURING CATEGORY A EVENT If the system operator declares a grid emergency during a category A event, the grid emergency will take priority. As water heating load generally would not be used to reduce load in a category A event, Orion would have water heating load available for load reduction when required for the grid emergency. This load would be shed, the System Operator advised and if more shedding is required the System Operator will instruct the Grid Owner to disconnect load as per the list of emergency load shedding feeders in NW20.40.05. After the grid emergency is cancelled the rolling outages pattern would continue.

16. ROLLING OUTAGES STRATEGY AND METHODOLOGY The Operations Manager, Control Centre Manager, and Release Planning Manager will review weekly targets and prepare plans for weekly rolling outages based on savings required.

Issue Date 11.12.2014 NW20.40.09 Amendment No.05 Page 12 of 37 Orion NZ Ltd. Contingency Plan Security of Supply Participant Rolling Outage Plan

The methodology is:

- Each distribution feeder exiting a zone substation (or switching station, or group of feeders where they belong to a parallel or ring supply) will be named as a “Rolling outage feeder”.

- Rolling outage feeders will be assigned a priority according to the criteria specified in section 9. Rolling outage feeders in the same GXP area with the same priority will be grouped together for switching (creating 36 rolling outage groups, A1 to F6). Feeders that belong to AUFLS block 1 and 2, or alternative AUFLS feeders where implemented, will be excluded from rolling outage groups unless we apply the alternative AUFLS arrangements outlined in section 12.

- A set of switching schedules will be prepared for each rolling outage group. - A winter weekday morning (8am to 12pm) and an afternoon (1pm to 5pm) average energy volume will be estimated for each group, based on the average July daytime loadings.

- A plan will be prepared to target the required savings level, taking account of any under or over savings carried forward from earlier periods in the security of supply rolling outage plan. As far as possible, groups should be selected depending on the saving level required, as follows:

Savings required Priority groups used 0 to 5% 5 and 6 5 to 10% 3, 4, 5 and 6 Greater than 10% all groups

Further, as far as possible, the total outage durations should be determined to meet the following relationship:

Group Priority Relative duration 6 10 5 8 4 6 3 4 2 2 1 2

To the extent possible, outages should be programmed to be held during daylight hours, between 8am and 5pm, but extending into the evening where necessary to achieve the required savings level or accommodate switching logistics.

Unless advised otherwise by the System Operator, the rolling outages plan must provide sufficient time for switching of load to ensure that Orion’s load does not increase or decrease by more than 25MW in any 5 minute period. The Controllers carrying out switching are to monitor their activities in relation to this limit.

Having established the week ahead rolling outage plan and despite significant uncertainty in predicting customer behaviour during these types of events, Orion will use best endeavours to produce a rolling week ahead half hourly load for each GXP. This will be updated daily to reflect any adjustments to our plan and forwarded to the System Operator in the format outlined below.

Issue Date 11.12.2014 NW20.40.09 Amendment No.05 Page 13 of 37 Orion NZ Ltd. Contingency Plan Security of Supply Participant Rolling Outage Plan

Date: (table for each of the next 7 days) Trading period GXP name GXP name …….. 1 MW load MW load MW load 2 MW load MW load MW load ⇓ MW load MW load MW load 48 MW load MW load MW load

If Orion is unable for some reason to meet the load disconnection/restoration ramp rates, or if there is expected to be a material departure (greater than 20%) from the previously provided half hourly GXP load forecast / load profile, then Orion would communicate directly with the System Operator (i.e. the Security Coordinator) to ensure that real time security issues can be managed. Using the methodology and excluding current AUFLS feeders, indicative plans for savings are:

17. TARGET MONITORING To avoid discrepancy over the accuracy of different data sources, the System Operator will report on actual demand versus the target. For load shedding to a weekly target, the Commercial Analyst will monitor the System Operator report of our savings results to our target and together with the Commercial or Operations Manager, review future load shedding to increase or decrease amount of rolling outages to enable the weekly target to be met. In parallel (as a check) with the System Operator, the Commercial Analyst will be responsible for daily and weekly reporting of consumption relative to target levels (using our data sources). In the case of daily or real time limits where the System Operator reporting will be too slow for real time action to be taken, the Operations Manager with the assistance of the Commercial Analyst will monitor our savings and adjust accordingly in the timeframe required. These savings will be calculated using GXP loads measured by our SCADA system and compared with the targets supplied by the system operator.

18. LOG OF ROLLING OUTAGES Controllers will enter in the Rolling Outage Log, times of disconnection and reconnection of all feeder interruptions. The log sheet to be used by Controllers is shown in Appendix B.

19. CONTINGENT EVENTS If an unplanned event occurs that will alter planned rolling outages, the Control Centre Manager will be responsible for all decisions. Where possible, any changes to the planned timetable should be published on Orion’s website and communicated to retailers.

22. APPENDIX C – DRAFT ROLLING OUTAGE PUBLIC NOTICE Electricity Supply Interruptions

Please read - your supply may be affected Orion is being required to reduce electricity consumption with rolling power outages across Christchurch and central Canterbury to meet a 5% savings target set by the Electricity Commission in response to the current energy crisis. Voluntary savings have already helped us reduce the impact of rolling outages, and further savings may allow us to reduce these planned cuts further. Outages will occur within the time periods noted in the schedule below. Wherever possible, we will delay cuts and restore power early, so please treat all lines as live. Within each area we have prioritised individual circuits to minimise the cost and disruption to our community, and timed outages accordingly. To find out the priority group of the circuit for your connection, you can enter your ICP number (from you power account) in the connection details search screen on our website (oriongroup.co.nz), or call your electricity retailer. YOUR SAFETY AND PROTECTION It is important to ensure you keep safe around electricity even when it is off. • Power may be restored at any time. • Please leave all appliances off during power cuts, particularly ovens and cook tops. • To prevent damage to computers and other electrical equipment turn power off at the wall prior to outages. Are you reliant on power ... If your health may be affected by these outages you will need to make alternative arrangements, or contact your health care provider for assistance. Please note that telephones that rely on a mains supply may not operate during outages, so plan in advance. Traffic lights will be affected by these outages, so please avoid travelling in the affected areas if possible. Avoid using lifts.
