The May 16 Order on Rehearing affirms FERC’s jurisdictional authority, and refuses calls for state opt-outs.
The Federal Energy Regulatory Commission (FERC or Commission) issued Order No. 841 early last year, a final rule amending FERC’s regulations to facilitate participation of electric storage resources in the capacity, energy, and ancillary service markets operated by regional transmission organizations (RTOs) and independent system operators (ISOs). Several entities have since challenged key aspects of the final rule, urging the Commission on rehearing to reverse course or modify its approach on a number of issues. On May 16, the Commission issued Order No. 841-A, denying those requests for rehearing, thereby upholding the initial rulemaking while providing some additional clarification.
