How PJM’s Regional Planning Process Prepares the Grid for the Future

2571

PJM has published a new, updated brochure explaining how PJM’s Regional Transmission Expansion Planning (RTEP) process works and how it benefits customers in the 13-state region PJM serves.

PJM’s RTEP process ensures that the transmission system continues to deliver power reliably and economically far into the future. The process and the grid enhancements that come out of it serve PJM’s core mission of reliability as well as reduce congestion costs and produce energy and capacity savings.

The new brochure explains the RTEP process over a number of a sections.

How the RTEP Process Works

The brochure notes how PJM identifies transmission projects that will be needed to serve customers into the future, planning for 15 years in advance. It also explains how, after a need is identified, PJM opens a competitive window where developers can submit project proposals to address one or more needs.

PJM then evaluates the proposals and makes a recommendation to the PJM Board for approval. Once approved, the designated developer becomes responsible for the project’s construction, ownership, operation, maintenance and financing, the brochure explains.

RTEP Helps the Transmission System Adapt to Change

The brochure discusses how the RTEP is helping the power grid adapt to change, addressing aging infrastructure, grid resilience and shifting fleet of generating resources.

The brochure also talks about the challenges of accurately formulating expectations for future load as consumer demand for electricity remains flat or is falling. PJM’s forecasting models directly reflect consumer behavior, weather, economics and behind-the-meter generation, as well as the influence of energy efficiency and demand response resources, the brochure says.

New Drivers for a Dynamic Planning Process

The brochure highlights how PJM and its stakeholders have worked to enhance the flexibility of the RTEP process so it can continue account for new drivers of grid enhancements. These drivers include:

  • Operational preparedness for disruptive events
  • Energy storage
  • Electric vehicles
  • Space weather
