Read our recent LawFlash analyzing the Federal Energy Regulatory Commission’s (FERC’s) Order No. 2222, which directs wholesale electric market operators to facilitate the participation of distributed energy resource (DER) aggregators under one or more participation models. The new rule vastly expands the opportunities for DERs, such as grid-enabled water heaters, small solar installations, and electric vehicles, to aggregate and compete alongside traditional generators for a slice of wholesale market revenues. ISOs/RTOs will have 270 days from the date the rule is published in the Federal Register to submit their compliance filings and propose implementation dates for their regions.
