Pepco Holdings Inc. (PHI) has notified the Maryland Public Service Commission and the Virginia State Corporation Commission that the company is requesting delays in the commissions' reviews of the respective applications filed by the utility's subsidiaries, Pepco and Delmarva Power, for state regulatory approval for the Mid-Atlantic Power Pathway (MAPP) transmission project.

The requests were filed following notification from PJM Interconnection that it has established a new in-service date for MAPP, a proposed high-voltage, 152-mile interstate transmission project planned to originate at the Possum Point substation in northern Virginia, traverse under the Chesapeake Bay and end at the Indian River substation in Delaware.

PJM’s notification states that the need for MAPP has moved from 2015 to the 2019-2021 time frame. However, PJM also noted that transmission planning “uncertainties could accelerate this schedule.” The letter states that PJM’s action “does not constitute a directive by PJM to cancel or abandon the MAPP project,” and also directs PHI to proceed with those development efforts “reasonably necessary to allow the MAPP project to be quickly restarted,” according to PHI.

The notification also states that PJM will be using a new stakeholder process to evaluate its transmission planning methods, which could lead to changes in PJM’s assessment of MAPP’s in-service date. PJM does not expect the new evaluation to be completed until sometime next year.

“Reliable power is critical to the economy and security of this region and the country,” says Joe Rigby, PHI’s chairman, president and CEO. “PHI remains committed to the MAPP project due to the many benefits it will provide to the region, including enhancing electric system reliability, transporting renewable wind energy from offshore to the Mid-Atlantic region and fueling economic growth.”
