In the second phase of the Pennsylvania Public Utility Commission's (PUC's) investigation into electric industry restructuring, Metropolitan Edison (ME) and Pennsylvania Electric (PE) have proposed a regional wholesale electricity market based on the Pennsylvania-New Jersey-Maryland power pool. All electric generators would sell into the market, which would function as a spot market, while accommodating bilateral contracts.
The pool would coordinate all power sales and purchases to assure the reliability and integrity of the regional electric grid. An independent system operator (ISO) would manage the pool-based market and would contract with pool members to settle reliability concerns and develop emergency procedures. The ISO would be responsible for regional transmission planning.
