PJM Electric Transmission Project Stalls
LCG, March 2, 2011--PJM Interconnection, the regional grid operator, indefinitely suspended the Potomac-Appalachian Transmission Highline (PATH) project due to declining load forecasts and a corresponding reduced need for grid improvements.
American Electric Power (AEP) and FirstEnergy Corp. (FE) Monday also announced that their affiliates will request to withdraw their applications for state regulatory approval to construct the $2 billion PATH project. The joint venture project included the construction of a 765-kV, 275-mile transmission line from Putnam County, West Virginia to Frederick County, Maryland. The Public Service Commission of West Virginia yesterday agreed to dismiss the application without prejudice.
PJM Interconnection plans to further analyze the potential need for PATH as part of its continuing Regional Transmission Expansion Plan. In 2007, PJM directed PATH to be built in order to improve grid reliability and meet forecast load growth, which has not materialized with the recent recession.
