During the late 1960s, three nuclear power plants were constructed in New England: Connecticut Yankee (590 MW, located in Haddam, Connecticut), Maine Yankee (870 MW located in Wiscasset, Maine), and Vermont Yankee (520 MW, located in Vernon, Vermont). Up to thirty-three New England utilities and municipalities participate in each. These units, called the Yankee units, are connected to the New England 345 kV transmission system. Built before the conception of the New England Power Pool (NEPOOL), these units rely on negotiated transmission agreements to implement the purchased power contracts. The Yankee Transmission Agreements were established to provide a mechanism for New England utilities, which provide the transmission wheeling services, to be adequately compensated for delivering the Yankee power. Under the agreements, the purchasing utilities (those utilities who purchase power from the nuclear plants) would pay into separate transmission funds based on their entitlement in the unit. The fund is then distributed among the transmitting utilities (those utilities providing the transmission wheeling services) based on the calculated use of their transmission systems. A methodology was established that could equal the units` life, offer flexibility to a changing system, and provide equitable results. This article describes how using commercially available software to automate simulations, perform the MW-miles calculation, and tabulate the results significantly reduces the time and computational effort to perform the wheeling calculations.
