TECHNICAL ANALYSIS

Construction of New Sta. Cruz Substation and 69 kV Subtransmission line from Candon to Sta. Cruz

The Candon Substation's Sta. Cruz and Candon feeders were experiencing under-voltage problem with 0.80 and 0.86 per unit voltage, respectively. These were measured at the farthest end of the line. Poor power quality problem was also observed in the areas being served by the Cancfr Substation which normally occurred at peak hours in far flung ar4d\,yriountainous areas supplied by the said substation. ili. / ERC Case No. 2011-123 RC DECISION/December 10, 2012 Page 28 of 62

The measurements of the voltage levels do not comply with the standards provided in the Philippine Distribution Code (PDC). The voltage levels at the customer's connection point must be within ±10% of the nominal voltage level of 230 volts or per unit values ranging 0.9 to 1.1.

ISECO believes that the ultimate solution to resolve this problem is to construct a new 5 MVA substation in Sta. Cruz with a corresponding 69 kV subtransmission line. It also proposes to install capacitors at strategic locations to correct the power quality at the said Sta. Cruz feeder.

The Commission observed that the proposed projects have the same purposes. Thus, ISECO should pursue only one (1) project considering that the said substation can sufficiently serve its areas for the next seven (7) years based on the loading analysis of the Candon Substation,. Shown below is a summary of the Candon Substation's loading analysis:

Interim cAPEx Period 1st Regulatory Period 2010 2011 2012 2013 2014 2015 2016 Rated MVA 15 15 15 15 15 15 15 Capacity Max. MW 18 18 18 18 18 18 18 Capacity Demand (MW) 11.49 12.09 12.75 13.47 14.26 15.10 16.01 % Loading 63.84% 67.17% 70.83% 74.84% *20% 83.90% 88.94%

The Commission considered the financial impact of the proposed projects based on a least cost criteria. It was established that other projects are least costs compared to the construction of a new 5 MVA substation in Sta. Cruz. Since the capacity of the Candon Substation is sufficient to address the power requirements of the coverage area, the construction of a new substation is not necessary. ISECO should instead pursue the proposed installation of capacitors within the Sta. Cruz feeder.

Acquisition of 69 kV Subtransmission Line and Refurbishment of Acquired 69 kV Subtransmission Line

On December 16, 2010, the National Transmission Corporation (TRANSCO) and ISECO filed a joint application with the Commission for the approval of the sale of various subtransmission lines/assets of TRANSCO within the franchise area of ISECO as covered by a Lease

Purchase Agreement docketed as ERC Case No. 2010-151 RC 1 .

Relative thereto, on August 15, 2011, the Commission issued a Decision approving with modification the aforesaid application. The approved cost for the purchase of the 69 kV amounted to PhP14,589,224.09, exclusive of the provision of a twenty percent (20%) down payment. The approved subtransmission lines to be acquired by ISECO are as follows:

a) San Esteban—Candon 69kV line; b) New Bantay—Sto. Domingo 69kV line; and c) San Esteban—Narvacan 69kV line (Tower 21 Take-off).

The Commission denied the acquisition of the San Esteban- Narvacan Junction (Old 115kV line) since it does not serve the purpose of delivering power to ISECO consumers.

Upon receipt of the Deed of Transfer of Possession of the approved subtransmission assets, ISECO proposed to refurbish these assets in order to extend its economic life and improve the power supply reliability of the cooperative. Refurbishment will include the replacement of rotten wooden poles, cross-arms and braces that contributed to power interruptions during rainy season.

In the Matter of the Application for the Appmval of the Sale of Various Subtransmission Lines/Assets of the National Trannission Corporation (TRANSCO) to llocos Sur Electric Cooperative, Inc. (ISECO) as coverfçI by an ApYended Contract to Self' ERC Case No. 2011-123 RC DECISION/December 10, 2012 Page 30 of 62

In the ocular inspection conducted by the Commission, it was disclosed that several poles and accessories of the said subtransmission lines were rotten and worn-out.

The refurbishment of the 69 kV lines would entail an amount of PhP10,684,037.18. The Commission recalculated the cost and determined that the cost should be reduced due to the exclusion of the sale of the San Esteban-Narvacan Junction (Old 115kV line). The other factors that contributed to the reduction of the project cost were due to the alignment of major materials, specifically the poles and the price benchmark provided in the 2012 National Electrification Administration's (NEA) Price Index. The said price index already includes five percent (5%) contingency and twelve percent (12%) Value Added Tax (VAT). Shown below is the breakdown of the total project cost:

Installation of Line Reclosers for Three (3) Feeders in 2010 and for Two (2) Feeders in 2011

Some of ISECO's existing feeders were found to have a minimum fault below the existing protection setting of the protection devices installed along the feeder lines. Based on the short-circuit analysis conducted by ISECO, the existing substation recloser could not determine the minimum fault current in the farthest end of the line in the event of minimum fault occurrences within the area. This situation poses danger to the safety of consumers living nearby these lines. Shown below is a summary of the short circuit analysis and existing minimum settingo eeders involve for additional back-up protection: I I , 1 ERC Case No. 2011-1 23 RC DECISION/December 10, 2012 Paae 31 of62

The feasible solution is to install additional backup recloser in the affected areas not detected by the substation's recloser. Fuses should not be used in three (3) phase system since this can only isolate faulted phase and affect the three (3) phase customers. Moreover, the automatic circuit recloser will solve the incapacity of the fuse to sense zero-sequence component.

Installation of additional reclosers near the downstream section of the line will serve as back-up protection in case of minimum fault occurrence. The existing reclosers at the substation could not isolate these occurrences. The proposed project will also provide reliability and improvement of the system since it will isolate the downstream section from the upstream section of the feeder in case of fault. The upstream customers will not be affected in case a fault occurred in the downstream section of the line.

Moreover, the energy curtailed or the Energy Not Served (EENS), System Average Interruption Frequency Index (SAIFI) per customer-year and System Average Interruption Duration Index (SAIDI) are significantly reduced. Shown below are significant reduction of EENS, SAl DI and SAIFI:

The Commission recalculated the total cost and determined that the cost of the proposed projects should be reduced. The cost adjustment was based primarily on the cost alignment of the required materials such as, conductors, cross-arms, and poles, with the price benchmark provided in the 2012 NEA Price Index.

Installation of Capacitors for Power Quality Correction for Two (2) Feeders of the Candon Substation

Sta. Cruz and Candon Feeders of the Candon Substation are presently experiencing power quality problem at medium voltage sections. Candon Feeder has a voltage of 0.88 per unit while Sta. Cruz Feeder has a voltage of 0.80 per unit. These were measured at farthest end of the lines which are not in compliance with the standards provided in the PDC.

ISECO proposed to implement the following: 1) installation of six (6) units of 50 kVAR capacitors and four (4) units of 25 kVAR capacitors within the Sta. Cruz Feeder; and 2) installation of three (3) units of 25 kVAR capacitors within the Candon Feeder. The existing performance assessment of the feeders and the strategic location of the proposed capacitors are shown in the following figures:

Installation of I MVA Auto Voltage Regulator (AVR) for San Juan Feeder

The Santo Domingo Substation/San Juan Feeder is presently experiencing power quality problem at medium voltage section. The said feeder has a voltage of 0.77 per unit which was measured at its farthest end of the line. Most areas with under-voltage are beyond the economic load reach of the particular circuit. The said measurement is not in compliance with the standards provided in the PDC.

To address the deficiency, ISECO intends to install three (3) units of single phase, 333 kVA Automatic Voltage Regulator (AVR) within the said feeder.

Reconfiguration/Splitting of Two (2) Feeders

The Candon Feeder of the Candon Substation and Bantay Feeder of the Vigan Substation are presently exposed to outages. The occurrence of outages in any one (1) of them is detrimental to the said customers considering that both feeders are serving large commercial consumers.

To improve the power supply reliability in these feeders, ISECO proposed the following: 1) reconfiguration and splitting of the Candon Feeder in two (2); and 2) reconfiguration and splitting of the Bantay s Feeder in two (2). The first (i ) proposed project includes the refurbishment of an existing line which was previously used by Philippine Tobacco Flue-curing Corporation (PTFC), a decommissioned commercial consumer of ISECO. The second (2nd) proposal includes the construction of a 1.695 km. double circuit three (3) phase line. The existing line configuration of the feeders and the proposed projects are shown in the following figures:

The proposed project will not only address reliability improvement but also provide a more efficient distribution system in the areas served by the said feeders. EENS of the Candon and Bantay Feeders will improve by forty eight percent (48%) and twenty seven (27%) percent, respectively. Shown below are the indications of technical system loss reduction by an average of seventeen percent (17%) and twenty seven percent (27%), respectively, within five (5) years:

Since the project is intended to optimize the distribution system, ISECO assessed its economic viability upon implementation. Based on its assessment, the proposed project is viable since its Net Present Value (NPV) is positive and the Benefit-Cost Ratio is greater than one (1). The assessment was based on five (5) years effectivity period exclusive of any discount rate considering that the project will be funded through its Reinvestment Fund for Sustainable Capital Expenditures (RFSC). Shown below is a summary of the assessment:

Conversion of the Secondary Lines

ISECO has utilized #6 AWG duplex wires as service drop and service entrance on some of its residential consumers which were filled on improvised lift poles. This type of installation is hazardous since it can cause electrocution due to overloading of the conductor. It is also not in compliance with standards set by the Philippine Electrical Code (PEC), particularly on the required minimum height clearances forservice entrance.

The conversion of these lines to underbuilt or open-secondary will prevent accidental electrocution and overloading and deter the commission of pilferages.

ISECO proposed the rehabilitation and upgrading of service drops from #6 duplex wires to #2 or #2/0 duplex wires. Shown below is a summary of the project costs requirement:

Installation of Distribution Transformers (DTs)

The installation of additional distribution transformers is a continuing process to address load growth. Additional loads require additional capacity in the secondary network.

The distribution transformer (DT) requirement was predicted based on the 7-year historical trend of the installed communal transformers in the distribution system. The historical and forecasted number of customers were used as the regressor to predict the annual DT requirement. The forecasted model used to determine the quantity of DT requirement is represented by the equation: DT = 198.7924 + 5.7153t + 0.0069t3. The chosen model passed and met all the criteria necessary to validate the accuracy of the forecasted model. The said model has an Adjusted R 2 of 0.99218 and a MAPE of 2.3049%. Meanwhile, the predicted annual quantity of DT per capacity is an allocation based on the percentage sharing of capacity for the year 2009.

CAPEX for Low Voltage Distribution Lines

ISECO proposed the expansion of its secondary network to provide secondary lines for the predicted new residential consumers and other 230-volt customers.

The predicted secondary expansions were based on a seven (7) year historical trend of secondary line construction projects. The historical and forecasted residential connections were used as the regressor to determine the length requirement of the secondary distribution. The regression model used to establish the required length of tines is represented by the equation: SL = 471.481 + 1.6552t2 - 0.05478t3. The said model passed all the necessary testing to validate the accuracy of the forecasted model. The said model has an Adjusted R 2 of 0.99714 and a MAPE of 0.421%.

The Commission has recalculated the proposed project costs and determined that said costs should be reduced in view of the following: a) The cost alignment of some materials, specifically the required poles and wires, was based on the price benchmark provided in the Commission's Valuation Handbook; and b) The said price index already includes five percent (5%) contingency and twelve percent (12%) Value Added Tax (VAT).

New Low Voltage Customer Connection Requirements

ISECO is committed to provide distribution services and connections to its distribution system network consistent with the PDC.

Load growth dictates the addition of new equipment and assets to forecast the number of new connections. Forecasting of new customers was based on a seven (7) year historical customer data of ISECO. Each of customer types was forecasted separately to capture the best model for each customer type. The model adapted in the customer forecast of the whole system is represented by the equation: Customer = 106,453 - 10,347f 1 + 436t2. The chosen model passed and met all the criteria necessary to validate the accuracy of the forecasted model. The said model has an Adjusted R2 of 0.99617 and a MAPE of 0.446%.

With the determination of the total number of customers per year, the annual additional number of customers will then be identified by subtracting the forecasted number of customer in a year from the total number of customers for the year 2009.

The Commission recalculated the proposed project costs and determined that said costs should be reduced in view of the following: a) The cost alignment of some materials, specifically the required poles and wires, was based on the price benchmark provided in the Commission's Valuation Handbook; and b) The said price index already includes five percent (5%) contingency and twelve percent (12%) Value Added Tax (VAT).

This office building will serve as collection and payment center for the town of Cervantes, Quirino and Suyo. It will also serve as venues for official business or institutional meetings and as stock room for the materials acquired for serving the abovementioned towns. The proposed project would provide collection efficiency and improve services to its consumers.

The Commission reduced the project cost due to the modification of the labor cost and contingency allotment using the twenty five percent (25%) and five percent (5%) of the material cost. Shown below is a summary of project cost:

Acquisition of Total Utility Billing and Collection System - TUBS

ISECO's existing billing, collection and meter reading systems were used since 2003. In the event that this system will have to be revised or additional program processes are needed, ISECO will require the service provider source code. However, there were instances that the said provider could no longer accommodate the immediate request of ISECO. Certain program processes and report generation is not accurately performed by its existing system. For instance, the back-end database (Fox Based) used by the said system is not ideal for enterprise level operation and requires higher bandwidth in order to operate in WAN environment.

ISECO intends to replace its entire existing Computerized Electric Billing/Collection with a precise and updated type of system to aid the management in decision-making. It proposed to purchase a new system that applies industry standard development software and SQL as backend database. It shall also feature a complete auditing trail of transactions and high level of security. The overall design of the systeny'all comply with current demands of the ERG Gase No. 2011-123 RC DEGISION/December 10, 2012 PaQe 51 of62

Acquisition of SynerGee Software Protection Module and SynerGee Software's Maintenance Fees

ISECO will procure computer software to enable its engineers to perform evaluation of the protective devices of its distribution system. If not properly evaluated and damage to equipment occurs, its systems reliability and consumer safety will be adversely affected.

The software program that it intends to purchase is the SynerGee Software Protection Module which is designed to provide useful engineering information about coordination problems or settings problems that may exist among the protective devices in the system. It has the protection coordination analysis application that will evaluate the characteristics of fuses, reclosers, breakers, and sectionalizers with the use of the said software, coordination of these devices throughout the system will be examined, verified overcurrent coordination among protective devices as well as the protection of transformers.

The said software requires a maintenance fee which will be paid annually to the supplier. ISECO already had another SynerGee program (Load Flow Analysis Software) from the same supplier but with different function. It also proposed to include its maintenance fees to this project.

COST ANALYSIS

ISECOs' proposed Cost estimates included the corresponding economic and financial analysis. The estimated cost of its network and non-network projects were based on the NEA Price Index and standards on specific Construction Assembly Units for electric distribution system. It also includes acquisition cost of the needed materials, taxes and labor. On the other hand, the estimated cost for non-electrical capital projects such as the power transformers, circuit breakers, sets of testing equipment and computer generated programs to be acquired by the cooperative was determined based on the prevailing market price with the assistance of Professional Engineering Consultants and were subjected to public, transparent and competitive biddings.

The Commission evaluated and assessed the entire cost estimates of the recommended projects for capitalization by ISECO. The cost assessment was based primarily in reference with the ERC Valuation Handbook pursuant to Resolution No. 17, series of 2010 entitled "A Resolution Adopting the Valuation Handbook for the Optimized Depreciated Replacement Cost Valuation of System Fixed Assets of Privately Owned Distribution Utilities Operating Under Performance-Based Regulation (PBR)" and the latest NEA Price Index for the year 2012. The proposed cost estimates that has exceeded the benchmark provided in the said ERC Valuation Handbook or the NEA price index were reduced while the estimated costs that are close to the said benchmarks were retained. ERC Case No. 2011-123 RC DECISION/December 10, 2012 Paqe 53 of62

Considering disapproval and cost reductions of some of the proposed projects, the recommended estimated project cost is shown below:

ISECO has included in its application an annual inflation rate 2 factor of three percent (3%) to cover the future cost of projects. However, as can be gleaned from the above tabulation, the proposed costs of several materials are higher than the NEA price references. The Commission finds ISECO's proposed inflation rate not meritorious considering that the NEA price benchmark already includes contingency and inflation rate factor of five percent (5%) of the total material cost and that the published breakdown of project cost was not incorporated with the said inflation rate.

2 Inflation rate is a measur • the rate of increase of a price index such as the consumer price inde, ntage rate of change in price level over time, usually one year. ERC Case No. 2011-123 RC DECISION/December 10, 2012 Page 54 of 62

AUTHORITY TO SECURE LOAN

ISECO seeks authority to secure loan from NEA and other financing institutions to finance its capital expenditure projects. The National Transmission Corporation (TRANSCO) also offered the cost of its subtransmission asset in the amount of PhP19,527,464.00. Shown below is the breakdown of ISECO's financiers:

Amount to be Loaned (PhP) Financing Source Total (PhP) 2010 I 2011 I 2012

NEA and several private banks have certified that they will finance ISECOs capital projects in the amount enumerated in the table above. The proposed principal amount was based on the projects it specified. The proposed loan conditions of NEA constitutes a fifteen (15) year loan term with annual interest rate of nine percent (9%) while the private banks shall be for a five (5) year loan term with annual interest rate of 7.0225%, subject to their respective present lending policies on loan approval and releases.

ISECO proposed a staggered scheme on NEA's and private bank loan releases. The release shall be on an annual basis as projected in the annual implementation of the projects. Funding for annual requirement shall be given before the periodic implementation of the project. Meanwhile, ISECO's Audited Financial Statements (AFS) for the base year 2009 and the projected financial statements with the implementation of the projects for the applied CAPEX years are as follows: -

The preceding tabulation above shows that with the implementation of the projects, Operating Margin (EBITDA 3) will increase from a negative amount to as high as PhP42.824 Million by year 2012 and with an annual growth of PhPI6.252 Million. Moreover, the expected social and economic benefits of these projects may not be realized if the network will remain in its existing condition. Investments and financial obligations appear stable so long as ISECO would be able to manage its cash flows and implement its capital projects.

RATE IMPACT ANALYSIS

Considering the modification of the total CAPEX requirement of ISECO, the loanable amount from the aforesaid financing institutions should be as follows:

Annual Project cost i Amount to be Loaned Financing Source (PIP) Total (PhP) 2010 1 2011 2012

TransCo - 14,589,224.09 - 14,589,224.09

Private Banks - 44,911,580.14 24,000,000.00 68,911,580.14

Grand Total (PhP) - 92,576,511.05 55,425,864.72 148,002,375.77 • the recommended principal amount to be loaned from TransCo has been approved as per Decision issued on August 15, 2011 under ERc Case No. 2010-151 RC

The principal amount of PhP148,002,375.77 that ISECO should avail was derived on the basis of ISECO's projected cash flow on RFSC in order to mitigate the additional interest expense and to maximize the utilization of its RFSC revenues.

The Commission simulated the probable effect of ISECO's existing RFSC rate if it opted not to avail of any loans and utilize its expected revenues from the RFSC in financing the entire capital expenditure projects. Shown below is the Commission's simulation, to wit:

Based on the above simulations and as discussed earlier, ISECO should secure loans and utilize its RFSC funds to finance its proposed project in order togiitigate the rate impact to its consumers. ERC Case No. 2011-123 RC DECISION/December 10, 2012 Pace 58 of 62

ISECO should exert best effort in negotiating for a longer and better terms on all its borrowings in order to negate any possible increase in its RFSC rate without compromising the needs of its distribution system and for the benefit of its consumers.

A perusal of the evidence presented herein showed that the approval of ISECO's 2010 to 2012 capital expenditure projects in accordance with the provisions of Republic Act No. 9136 and the "Resolution Amending the Rules for Approval of Regulated Entities' Capital Expenditure Projects" will redound to the benefit of its consumers in terms of continuous, reliable and efficient power supply as mandated by Republic Act No. 9136, or the Electric Power Industry Reform Act of 2001 (Section 2. Declaration of Policy - (b) "to ensure the quality, reliability, security and affordability of the supply of electric power').
