Dominion Pushes IMM Tariff at FERC
Dominion Resources, Inc. (DRI) has asked the Federal Energy Regulatory Commission (FERC) to declare its proposed "impacted megawatt mile (IMM)" tariff a just and reasonable method of pricing transmission service.
The IMM tariff would base electric transmission prices on the actual flows that result from each transmission service, taking account of the size and distance of power flows on all affected lines, the direction of the flows, line loadings, and the costs of relieving any congestion.
