PJM, CAISO and SPP took a step closer to the full implementation of Order 841 with FERC’s partial acceptance of their Tariff revisions.

FERC issued orders implementing rulemaking to eliminate barriers to energy storage’s participation in electric markets, accepting PJM's and SPP's proposals.

FERC issued deficiency letters to all six jurisdictional RTOs and ISOs over their proposed energy storage rules, pressing for definitions, tariff citations and other details.

RTOs and ISOs filed tariff revisions to provide energy storage resources more opportunities to participate in markets in compliance with FERC Order 841.
