You may have seen information in the news about the Maryland Piedmont Reliability Project (MPRP). The MPRP is an approximately 70-mile-long high-voltage electricity transmission proposal awarded to developer PSEG by PJM, the regional grid operator. The Piedmont line is part of a package of transmission projects (called the “Window 3” projects) that the regional transmission operator, PJM Interconnection, LLC, determined are needed to address transmission system reliability needs. PJM determines system reliability needs based on forecasted electric power demands in the PJM region and the resources available to meet those demands.
