Public Engagement Process Commences for Maryland Piedmont Reliability Project

Project in Baltimore, Carroll and Frederick counties will enhance electricity reliability in the region


(June 17, 2024 – NEWARK, N.J.)  PSEG today announced the public engagement process, including the launch of a website and public information sessions, for the Maryland Piedmont Reliability Project (MPRP), a 500,000-volt (500 kV) transmission line designed to respond to growing electric needs in Maryland and the surrounding region. PSEG is committed to working with area stakeholders and encourages public input through the ongoing routing process.

The MPRP is a system (grid) enhancement (update) that has been awarded to PSEG by PJM, the independent Regional Transmission Organization (“RTO”) responsible for operating and planning the regional electric grid in all or parts of thirteen states, including Maryland.  Transmission reliability is key to supporting Maryland’s energy future.

A series of public information sessions will be held between July 9-11 where the public can learn more about the project and offer comments to the project team. Open houses will be held in Baltimore, Carroll and Frederick counties and include project leaders to answer questions about the project.  Detailed maps showing the different routes being considered for the proposed transmission line will be available for review and feedback.

The schedule is as follows:

Baltimore County: Tuesday, July 9, Session #1: 2 p.m. to 4 p.m., Session #2: 6 p.m. to 8 p.m.
         The Summit Manor, Hereford Vol. Fire Co. Station 44, Gunpowder Rm.
         510 Monkton Rd., Monkton, MD

Frederick County: Wednesday, July 10, Session #1: 2 p.m. to 4 p.m., Session #2: 6 p.m. to 8 p.m.

Carroll County: Thursday, July 11, Session #1: 2 p.m. to 4 p.m., Session #2: 6 p.m. to 8 p.m.
          Westminster Senior & Community Center
          125 Stoner Ave., Westminster, MD

Ahead of the open houses, the public is invited to learn more about the project at by contacting us at or 833-451-MPRP (6777).

The new overhead line will be built in the Piedmont Plateau region of Maryland.  The proposed transmission study area 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 project is expected to go into service (when the project delivers power) in June 2027.
