MARYLAND (WBFF) — Completion of the proposed Maryland Piedmont Reliability Project transmission line might be delayed until late 2028 under a revised schedule, despite warnings from regional grid operator PJM Interconnection that Maryland could face “system collapse and blackouts” as soon as June 2027.
Utility company PSEG filed a revised procedural schedule with state regulators May 22 that would move final post-hearing briefs from February 2027 to June 2027 and set a target final order date of July 30, 2027. The Public Service Commission has not yet announced a decision on the revised schedule.
PSEG spokesperson William Smith said construction will take 15 to 18 months after final approval — putting completion closer to late 2028. PJM’s requested in-service date is still June 2027, Smith said.
The proposed 67-mile, high-voltage transmission line would stretch across Baltimore, Carroll and Frederick counties to “increase the amount of available electricity to the state and diversify the grid geographically,” according to PSEG.
