Revisions aim to build on framework designed originally for pumped-storage hydro facilities and bring region closer to Order No. 841 compliance.
Earlier this year, the Federal Energy Regulatory Commission (FERC or Commission) issued Electric Storage Participation in Markets Operated by Regional Transmission Organizations and Independent System Operators (Order No. 841), 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). As we reported previously, Order No. 841 requires RTOs and ISOs to devise an electric storage resource participation model that meets certain general criteria. The RTOs/ISOs must file the tariff revisions directed by Order No. 841 by December 3, 2018, and implement those changes, if approved, by December 3, 2019.
