AMENDMENTS TO PREAMBLE OF THE CY AGREEMENT - ---------- ------------------------------------------ A. In order to reflect (1) the addition of Maine Electric Power Company as a party to the CY Agreement, (2) the merger of The Hartford Electric Light Company into The Connecticut Light and Power Company, (3) the change of name of New Bedford Gas and Edison Light Company into Commonwealth Electric Company, and (4) the payment of transmission charges by only those parties who receive transmission service under the CY Agreement, the preamble to the CY Agreement is amended as follows: CONNECTICUT YANKEE TRANSMISSION AGREEMENT, dated as of October 1, 1964, between The Connecticut Light and Power Company, New England Power Company, Boston Edison Company, The United Illuminating Company, Western Massachusetts Electric Company, Central Maine Power Company, Public Service Company of New Hampshire, Montaup Electric Company, Cambridge Electric Light Company, Central Vermont Public Service Corporation, Vermont Electric Power Company, Inc., Commonwealth Electric Company, and Maine Electric Power Company. Connecticut Yankee Atomic Power Company ("Connecticut Yankee") is constructing a nuclear electric generating unit at a site adjacent to the Connecticut River at Haddam Neck, Connecticut. The unit has been designed to have an initial electrical capacity of approximately 490 emw gross and 463 emw net, and is presently scheduled for commercial operation on or before October 1, 1967. The parties to this agreement except for Vermont Electric Power, Inc., Commonwealth Electric Company and Maine Electric Power Company are stockholders of Connecticut Yankee, and by separate power contracts dated as of July 1, 1964 have contracted to purchase the entire net electrical capacity and output of the Connecticut Yankee unit in the following percentages: The Connecticut Light and Power Company . . . . . .34.5% New England Power Company . . . . . . . . . . . . .15.0% Boston Edison Company . . . . . . . . . . . . . . . 9.5% The United Illuminating Company . . . . . . . . . . 9.5% Western Massachusetts Electric Power . . . . . . . 9.5% Central Maine Power Company . . . . . . . . . . . . 6.0% Public Service Company of New Hampshire . . . . . . 5.0% Montaup Electric Company . . . . . . . . . . . . . 4.5% Cambridge Electric Light Company. . . . . . . . . . 4.5% Central Vermont Public Service Corporation . . . . 2.0% ----- 100.0% Vermont Electric Power Company, Inc., Commonwealth Electric Company and Maine Electric Power Company are not stockholders of Connecticut Yankee, but transmit Connecticut Yankee power over their systems to such stockholders and are deemed to be parties to this agreement. Deliveries under the Connecticut Yankee power contracts will be made at the site at a nominal voltage of 345 kV. This agreement provides for transmission of the power purchased by the Connecticut Yankee stockholders over the interconnected facilities of the parties for delivery to the individual systems of the stockholders of Connecticut Yankee who have a common interest in the Connecticut Yankee Unit. It is the intent of the parties that a uniform transmission charge shall be payable for each kilowatt of Connecticut Yankee capacity by each party for whom transmission services are rendered, and that the changes so assessed shall be paid to the transmitting parties in proportion to their respective transmission responsibilities. SECTION 2. AMENDMENTS TO OTHER PROVISIONS OF THE CY AGREEMENT - ---------- -------------------------------------------------- A. The first sentence of the first paragraph of Section 4 of the CY Agreement is amended to read as follows: Each party for whom transmission services are rendered pursuant to this agreement (as shown on Appendix C, as amended from time to time) shall pay a transmission charge at the annual rate of $3.09 per kilowatt of its capacity entitlement under the Connecticut Yankee power contracts. B. The third paragraph of Section 4 of the CY Agreement is amended by adding a third sentence that reads as follows: The methodology of determining receipts shall be based on the kilowatt-miles of transmission capacity made available by a transmitting party. C. The CY Agreement is amended by adding new Sections 10 and 11, as follows: 10. Right of Transmitting Parties to Change Rate Schedules. --------------------------------------------- Each transmitting party reserves the right to submit for filing without the concurrence of any other party other rate schedules modifying or superseding this Agreement, subject to Section 11 below, and each party reserves the right to object to such rate schedules. Any changes to transmission charges proposed by The Connecticut Light and Power Company shall be based on the methodology used to determine the transmission charges under the Amendment to the Maine Yankee Transmission Agreement dated January 19, 1994 and the Amendment to the Vermont Yankee Transmission Agreement, dated January 19, 1994. The assumptions and methods used to determine the transmission responsibilities of the parties as shown in Appendix A, does not set a precedent for redetermination of such responsibilities under any future Amendments to the CY Agreement. 11. Moratorium on Changes to Assumptions and Methods. ------------------------------------------------- None of the parties shall seek an effective date prior to the expiration of three (3) years from the effective date of this Amendment, for any changes to the transmission charge, distribution of revenues, assumptions and methods or appendices specified in the CY Agreement as amended hereby. All parties hereby reserve their rights, individually and jointly, to protest, support or otherwise intervene in any proceeding involving a change in the transmission charge, distribution of revenues, assumptions and methods or appendices of the CY Agreement or this Amendment.
