PJM Board Approves Latest RTEP Additions


The PJM Board of Managers has authorized additions to the Regional Transmission Expansion Plan (RTEP), which ensures efficient and reliable power supplies for the 65 million people PJM serves.

The Board authorized a net $246 million in additional bulk electric transmission system upgrades to meet PJM reliability and deliverability criteria, and transmission owner reliability criteria under FERC Form 715. The Board endorsed new baseline projects totaling around $265 million, and project cancellations and scope changes resulted in the net increase of $246 million. Details of the approved changes are posted on pjm.com and summarized below.

PJM Reliability and Deliverability Criteria-Driven Enhancements

The PJM Board authorized $175 million in enhancements to the grid to address voltage violations and to meet PJM’s reliability criteria.

The largest of these projects comes out of a reassessment of reliability violations in the Jersey Central Power & Light transmission zone in the area of Red Bank, New Jersey. PJM and Jersey Central Power & Light worked closely to reevaluate the voltage violations and develop alternative solutions to a previous project to address concerns raised during regulatory proceedings in front of the New Jersey Board of Public Utilities. The recommended solution addresses the baseline needs in the area, uses existing infrastructure and is the most cost effective in light of these concerns.

FERC Form 715 Transmission Owner Criteria-Driven Enhancements

The PJM Board authorized $88.7 million in enhancements to the grid, driven by transmission owners’ reliability criteria under FERC Form 715. The largest of these projects includes transmission line rebuilds within the AEP and Dominion transmission zones. FERC Form 715 is the annual transmission planning and evaluation report that transmission owners must file with the Commission annually. The reports must identify the transmission planning reliability criteria that the transmission owner uses to assess and test the strength and limits of the transmission system.

How PJM Plans for the Future

PJM uses an open process to plan for changes to the electric grid in the 13-state region to maintain future reliability and economic performance of the grid. PJM’s process looks ahead 15 years, assessing many drivers that affect grid reliability. PJM studies many scenarios and analyzes various grid conditions that could lead to problems in the way power flows throughout the region.

When PJM identifies potential problems, it works with transmission owners and other members through a competitive planning process to determine the best solution for the problem, meeting required national standards.

The RTEP process determines the needs for the regional transmission system and the enhancements to meet those needs. It does not review or approve locations where transmission lines are ultimately built. That is the responsibility of individual states.

All transmission improvements identified through this process are discussed publicly in stakeholder meetings, and reviewed and approved by the PJM Board before being included in PJM’s expansion plan.
