Frederick and Carroll County Development Issues

Maryland Piedmont Reliability Project

The Maryland Piedmont Reliability Project (MPRP) is a critical system (grid) enhancement (update) that has been awarded to Public Service Enterprise Group (PSEG) by PJM, the Regional Transmission Organization (RTO) responsible for operating and planning the regional electric grid in all or parts of thirteen states, including Maryland.

The MPRP is a 500,000-volt (500 kV) transmission line designed to respond to growing electric needs in Maryland and the surrounding region. Transmission reliability is key to supporting Maryland’s energy future.

The approximately 70-mile proposed transmission route spans three counties, westward from the connection point within the existing Baltimore Gas & Electric transmission line right-of-way in northern Baltimore County, through Carroll County, and into the existing Doubs 500kV Station in southern Frederick County.

The current project seems to be driven in large part by the electricity needs of proposed data centers in Frederick County and northern Virginia.  We all recognize that electricity demand is growing rapidly, with the move away from fossil fuel for transportation and residential and commercial HVAC use.  However, this project appears to be moving forward across environmentally sensitive areas and private property without allowing time for significant input from environmental groups or affected residents.

There are several ways you can get involved. We will try to provide major updates on this page as they become available.  Also, a group of concerned citizens from Baltimore, Carroll and Frederick Counties have formed Stop MPRP.  Their website updates almost daily, and provides information on how you can help.  The most effective way is to make your voice heard, by showing up at meetings and writing letters to your city, county, state and federal legislators.  You are also encouraged to write the Maryland Public Service Commission at piedmontcomments.psc@maryland.gov.  Be sure your neighbors and friends are aware of the project, and encourage them to make their voices heard as well.
