Contracts, All Requirements


In addition to its jointly owned resources, MMWEC enters into bulk power purchase contracts and other arrangements to meet the power supply needs of its members as efficiently and economically as possible.

All-Requirements
MMWEC offers an All Requirements Power Supply Program through which program participants pool their electric loads and resources to achieve greater efficiency and economy in New England’s wholesale power marketplace. The All-Requirements participants delegate certain decision-making authority to an MMWEC program administrator, who can act on behalf of participants to complete certain transactions.

NYPA Contracts
MMWEC administers contracts and other arrangements covering the purchase and delivery of inexpensive hydroelectric power from the New York Power Authority (NYPA) to Massachusetts municipal utilities. Under an agreement with the Massachusetts Department of Telecommunications & Energy (DTE), the official Massachusetts bargaining agent for NYPA power, MMWEC acts as the agent for DTE in overseeing the Massachusetts allocations of power and energy from one federally licensed, NYPA-operated hydroelectric projects in New York.

MASSPOWER Contract
MMWEC is receiving approximately 21 megawatts of power and energy from the MASSPOWER Project through a 20-year contract that runs through 2013. MASSPOWER is a 270-megawatt, gas-fired, combined-cycle plant located in Springfield, Mass., that began operating in 1993. Power and energy from this contract is resold to the six contract participants at MMWEC’s cost.

Hydro-Quebec Interconnection
The Hydro-Quebec Interconnection is an approximate 2,000-megawatt, direct-current electric transmission line connecting central New England with the Canadian utility Hydro-Quebec. Construction of the U.S. portion of the interconnection, which stretches from Groton/Ayer, Mass. to the Canadian border in northern Vermont, was a joint effort of many New England utilities, including most Massachusetts municipal utilities. Thirty-two Massachusetts municipal utilities own usage rights over approximately 4 percent of the interconnection, either through MMWEC or independently. MMWEC owns approximately 1 percent of the stock in several of the companies that operate the interconnection on behalf of numerous municipals. MMWEC also manages the ownership interests of all but two of the Massachusetts municipals involved with the project.
