Key issues

• The total project cost to interconnect the Cape Vincent Wind Farm (“Cape Vincent”) to theNational Grid Transmission System is fully reimbursable by the customer.

• This project will interconnect to the new 115kV Rockledge Station, which is being

constructed for the interconnection of the St. Lawrence project (AMIC 0964), via a singlebreaker tap arrangement. The point of interconnection will be the Rockledge Station tap onthe existing bus. The wind farm is located in the Town of Cape Vincent in Jefferson CountyNY. The project’s collector stations will interconnect to the Rockledge Station via adeveloper owned, 6 mile 115kV transmission line. The NYISO has determined National Gridto be the connecting Transmission Owner, as per the NYISO Open Access TransmissionTariff (OATT).

• The total project cost and schedule are dependent on Rockledge Station being constructedand turned over to National Grid before the Cape Vincent project interconnection isconstructed. It is expected that System Delivery (internal RDV) will complete construction onthe National Grid work scope. This assignment will be made after the interconnectionagreement is signed. (See Appendix C for Draft Interconnection Agreement Milestone

Schedule.) • BP Alternative Energy NA, Inc. (“Developer”) is constructing a 210 MW wind generation farm

consisting of one hundred forty (140) GE 1.5 MW wind turbines which will be interconnectedin two phases. Phase I will comprise 95 turbines (142.5 MW) and Phase II will include theremaining 45 turbines (62.4 MW). The output from each turbine will be stepped up to 34.5kV through individual pad mount 690V/34.5kV, 1.75 MVA transformers. The 140 units will bedistributed over 13 radial 34.5-kV feeder lines which will be brought to two separatecollection stations, approximately 2 miles apart, one for each phase. At the collectionsubstations the power output will be transformed to 115 kV through two non-regulated, wye-grounded transformers, one for each phase. The Phase I and Phase II transformers will be115/34.5 kV, 95/127/160 MVA and 115/34.5 kV, 45/60/75 MVA, respectively.

• A new 115kV single breaker tap will be constructed at the Rockledge Station by NationalGrid and serve as the Delivery Point for the project. BP Energy will furnish and installmetering transformers and provide space for National Grid metering equipment, at itscollector station. The furnishing and commission of the RTU and Metering equipment will bedone at the customer’s expense per section 7.1 of LGIA. The project will also encompassrequired protection upgrades at National Grid’s Black River and Coffeen substations. Theseupgrades, as defined in the facilities study report, may require outages at the substations.

• All work performed by National Grid is 100% reimbursable as per the Large GeneratorInterconnection Agreement (“LGIA”) that the NYISO, BP Energy and NMPC are negotiatingand will execute, subject to Sanction Paper Approval. The LGIA is consistent with the Termsand Conditions of Attachment S and X of the NYISO OATT and will be filed at the FERCupon execution.

• The construction of the project is expected to be completed by October 2014. It isanticipated that the LGIA will be executed in the 3rd quarter 2010.

• This project is in the fiscal year 10/11 business plan with budget dollars in fiscal years 11and 12. Budgeted dollars will need to move from FY 11/12, to FY 12/13, 13/14, 14/15 andFY 15/16. The total budgeted capital dollars is $615,000 more than the estimated projecttotal cost presented herein. Place holder funding numbers are CNYX60 and CNYX60R.

• The commercial terms and the project execution schedule are subject to the pendingapproval of the Large Generator Interconnection Agreement (“LGIA”) between NMPC, BPEnergy, and the New York Independent System Operator (“NYISO”) by the Federal EnergyRegulatory Commission (the “FERC”).



National GridMIC 10032

• Tax obligations associated with the project will be the responsibility of BP Energy, in

accordance with Article 5.17 of the LGIA.

• Outages will be required. These outages will be defined and outage and construction plans

created after the Interconnection Agreement is executed and BP Energy has issued the

authorization to proceed, as per step 2A of the playbook. Final e - igineering design, and

outage and construction plans will be completed so as to ensure minimization of outage

requirements.

Capital/Revenue Investment Proposal

APPLICATION BY NIAGARA MOHAWK POWER CORPORATIONTO INSTALL A 115kV GENERATOR ATTACHMENT FACILITY

AND PERFORM MISCELLANEOUS FACILITIES WORK TO ACCOMMODATE THECONSTRUCTION OF THE CAPE VINCENT WIND FARM GENERATION FACILITIES

Transmission Line/Station, NMPC, Project No. B04627, CNYX60

(A sanction paper by Francis Kane and sponsored by Mary Ellen Paravalos – March 19, 2010)

1. Background

In January 2006, BP Energy submitted an Interconnection Request to the NYISO for the CapeVincent Wind Farm Project (“Cape Vincent Wind”) to identify the means with which tointerconnect the 210 MW wind farm generating facility to the company’s transmission system.As per Attachment S and X of the NYISO OATT, the NYISO has deemed National Grid to bethe Transmission Owner for this project.

The total estimate for the company’s work on the Cape Vincent Wind Project is estimated to be$2,634,000. BP Energy is responsible for all actual costs.

An Interconnection Agreement is being negotiated between National Grid, BP Energy andNYISO. Sanction approval is required prior to National Grid entering into the agreement.Section 11.5 of the LGIA ensures full cost recovery for National Grid and payments by the

interconnecting customer.

2. Driver

BP Energy has filed an Interconnection Request in compliance with the NYISO OATT. NationalGrid has been deemed to be the Connecting Transmission Owner and is required to provide thetransmission interconnection for this project. A feasibility study, system reliability impact studyand facilities study have been performed to determine the technical requirements, cost andschedule for the proposed interconnection. An Interconnection Agreement is being negotiatedbetween National Grid, BP Energy and NYISO. Sanction approval is required prior to NationalGrid entering into the agreement.

This project is mandatory and has been given a risk score of 49, customer driven.

3. Project Description

The project includes engineering, design, and construction of a single break tap at theRockledge Station, protection upgrades at Coffeen and Black River substations, and installationof an RTU and revenue metering at the Cape Vincent Wind collection station.

The system upgrades at Coffeen substation are associated with the addition of Cape VincentWind substations and single breaker tap at the Rockledge Station. The Line 3 and Line 5 CTratios will be raised to 500/5, and existing line relays reset. To prevent islanding of the CapeVincent Wind Farm when the Coffeen R40 breaker opens, dual channel DTT transmit will beinstalled to trip the wind farm when the line breaker opens.

The system upgrades at the Black River substation are associated with the addition of the CapeVincent substations and single breaker tap at the Rockledge Station. The Line 3 CT ratio will beraised to 500/5, and existing line relays reset.




5 of 16

Outages will be required for some of the work at the stations. These outages will be defined andoutage plans created after the Interconnection Agreement and Authorization to Proceed, as perstep 2A of the playbook. Final engineering design will be completed so as to ensureminimization of outage requirements.

National Grid will provide to BP Energy (at BP Energy’s expense) an RTU to be installed by BP

Energy at its collection substation.

New revenue metering and associated data links will be installed at the Rockledge station andCape Vincent collection station.

Engineering review and field inspection of Cape Vincent’s stations will be completed bycustomer facilities engineer.

Any and all National Grid transmission and distribution facility relocation costs caused by the

Project. National Grid will work with the developer to identify these areas as soon as possible.These costs have not been identified and are not included in this sanction paper.

4. Business Issues

Consistent with the provisions of Attachment S and X of the NYISO OATT, this is a fullyreimbursable project for National Grid. National Grid has been deemed to be the TransmissionOwner. A Large Generator Interconnection Agreement (“LGIA”) is being drafted by the threeparties, and its terms and conditions with conform to the pro-forma language of Attachment X.The LGIA will be filed at the FERC.

A brief summary of some key Articles in the Large Generator Interconnection Agreement can befound in Appendix B to this sanction paper.

5. Options Analysis

- The project was studied by incorporating the procedures of the NYISO OATT, Attachment X -Large Generator Interconnection. As this connection is mandated under the NYISO FERCElectric Tariff, OATT, Attachment X, Large Generator Interconnection Procedures andAgreement (“Attachment X”), “Do Nothing” is not an option.

- Construct a new single breaker tap at the Rockledge Station to serve as the interconnectionfacilities for the Cape Vincent Wind Farm Project. This is the recommended option.

7. Safety, Environmental and Planning Issues

Substation work will be completed so as to minimize load impacts. Appropriate safetyprecautions will be taken to accomplish this work.

During the work at Rockledge, Black River and Coffeen substations, specific attention will begiven to any work that will be done around energized equipment in the control buildings.

All necessary permitting and property rights (ROW, easements or land transfer) are theresponsibility of, and will be obtained by, BP Energy.

National Grid will make clear and separate distinction between the work done by BP Energy andthe Company so as to avoid potential environmental impacts during the course of the work.

BP Energy is responsible for obtaining all the necessary local and state approvals for the projectto go forth.

BP Energy’s 34.5kV and 115kV lines, including their communication circuits for protectionsystems, may be crossing National Grid-owned distribution circuits. All line outages will be

coordinated with Regional Control, in accordance with applicable Regional Control Procedures.

Outages will be required for some of the work at the stations. These outages will be defined andoutage plans created after the Interconnection Agreement and Authorization to Proceed, as perstep 2A of the playbook. Final engineering design will be completed so as to ensureminimization of outage requirements.

The outreach level for this project is considered low. Most National Grid work will be withinexisting substations. The developer will be responsible all permitting and rights of way.

National Grid will engineer, design, procure, construct and test all changes and upgrades atexisting facilities.

12. Cost Assumptions

The estimates, cost responsibility, payment provisions and the project execution schedule aresubject to pending approval of the Large Generator Interconnection Agreement (“LGIA”)between NMPC, BP Energy, and the NYISO by the Federal Energy Regulatory Commission(“FERC”).

This estimate (±20%) is for the identified work. However, BP Energy is responsible for paying allof National Grid’s actual costs. Cost recovery is addressed in the LGIA, Article 11 – Performance Obligations, which includes, by reference, Attachment S and Attachment X of theNYISO OATT. If Congestion costs are incurred with this project, efforts will be made tominimize these costs to the furthest extent possible. The (LGIA) allows NG to petition forrecover of these costs from the developer.

The entire $2, 726,000 estimated cost will be paid in accordance with Article 11 and 12 -Performance Obligations and Invoice, respectively, of the LGIA by BP Energy. Article 17 of theLGIA addresses Default issues and Article 18 of the LGIA addresses Indemnity, ConsequentialDamages and Insurance, consistent with Attachment X of the FERC Electric Tariff NYISOOATT.

This project will not create an income tax liability for National Grid per Article 5.17 of the LGIA ,but it will create O&M, property tax and communications costs liabilities for National Grid as perSection 15 below.

During the Interconnection study process BP Energy has posted security and National Grid hasbeen reimbursed for actual costs. Following Attachment S and X in accordance with the LGIA,BP Energy will post security and will make monthly payments of actual costs incurred byNational Grid.

13. Benefits Summary

The entire $2, 726,000 estimated cost will be paid by BP Energy in accordance with the LGIA,Article 11 Performance Obligations and Article 12-Invoice. Article 17 of the LGIA addressesDefault issues and Article 18 of the LGIA addresses Indemnity, Consequential Damages andInsurance, in compliance with Attachment X of the FERC Electric Tariff NYISO OATT.

This project has been included in the approved business plan.

This estimate (±20%) is for the identified work. However, BP Energy is responsible for paying allof National Grid’s actual costs. Cost recovery is addressed in the LGIA, Article 11 – Performance Obligations, which includes, by reference, Attachment S and Attachment X of the

14. NPV

The project is not financially driven.




9 of 16

15. Additional Impacts

FERC orders have deemed the assets related to the Rockledge station to be both attachmentfacilities that NG will be able to charge the customer the associated ongoing O&M, PropertyTaxes, and communication circuit costs and system upgrade facilities for which National Gridwill be responsible after Cape Vincent is operational. This additional yearly expenditure will bein the range of $100,000. Additional property taxes and O&M associated with the facilities

upgrades at the existing stations are expected to be negligible.

16. Execution Risk Appraisal

National Grid is in the process of negotiating, with BP Energy, a schedule that it considers to bea reasonable amount of time to complete its work. This schedule will be depicted in Appendix Bof the Large Generator Interconnection Agreement. In the event that project delays are incurred,there is a Reasonable Efforts Standard definition that applies. (A draft of the milestone scheduleis in Appendix C to this paper.)

This project has a direct interaction with the St. Lawrence Wind Project (AMIC 0964), underwhich Rockledge Station is to be constructed. Delay in the construction and energization of the

Rockledge Station will delay the interconnection construction for Cape Vincent Wind. Aresanction will be required, should material changes in the Rockledge Station schedule occur.

In the event the actual cost exceeds the estimated cost, BP Energy is responsible for the actualcosts. A brief summary of some key Articles in the Large Generator Interconnection Agreementcan be found in Appendix B to this sanction paper.

If BP Energy abandons the project prior to completion, in accordance with LGIA, Article 5.14,BP Energy will be responsible for National Grid’s costs. A brief summary of some key Articles inthe Large Generator Interconnection Agreement can be found in Appendix B to this sanctionpaper.

Outage and construction plans will be created after the Interconnection Agreement is executedand BP Energy has issued the authorization to proceed, as per step 2A of the playbook. Theseplans will be incorporated into the Scope document, which will be reviewed and approved priorto completion of Step 2A. If the approved Scope document differs from the approved sanction,then re-sanction requirements will be evaluated, and re-sanction completed, if deemednecessary.
