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

PJM dropped its plan to clarify pseudo-tie eligibility after stakeholders argued some of the revisions conflicted with pending litigation.

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

PJM told stakeholders all deadlines for upcoming capacity auctions will be suspended pending FERC action on the RTO’s proposed revisions to its capacity market.

A study concluded PJM’s proposed 10-hour rule for energy storage resources participating in the capacity market is “unnecessary and unduly restrictive.”

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.

The PJM Market Implementation Committee discussed the must-offer exception process and FERC’s energy storage order at last week's meeting.

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