Advanced Energy Perspectives

On September 17, 2020, FERC issued Order 2222, directing the grid operators under its jurisdiction to pave the way for aggregations of distributed energy resources (DERs) into wholesale markets. Recognizing that implementation of Order 2222 requires transmission and distribution system coordination and active engagement from state utility regulators as well, AEE and GridLab convened distribution utilities and AEE members for eight months to build consensus around key distribution system issues. The focus areas of the discussion included interconnection and aggregation review; communications, controls, and coordination; dual participation in both retail programs and wholesale markets; and investment recovery and cost causation. The result is a new understanding of the challenges in making DER participation in wholesale markets work, and ways that utilities, regulators, and industry can work together to overcome them.

Like anyone in construction, renewable energy developers are all too familiar with process hurdles and delays. But patience wears thin. In the vast PJM Interconnection region stretching from DC to Illinois, a huge pool of solar, wind, and battery storage projects are stuck in the grid operator’s Interconnection queue, often waiting years for technical and cost studies and final approvals needed to connect to the grid. This usually behind-the-scenes issue moved to center stage this month when PJM proposed a dramatic step: a two-year pause on formally accepting new interconnection applications so that the grid operator can focus on speeding up delayed projects and clearing some of the backlog. That pause will come with much needed improvements to PJM’s processes to speed up future interconnection requests. Those improvements won’t solve all the problems with PJM’s interconnection process, but they are a good start, and they can’t come soon enough.
