MISO offered its energy storage participation proposal for final stakeholder inspection while promising to introduce more new market rules in the future.

FERC accepted MISO’s compliance filing spelling out rules for its new energy storage category, rejecting a protest and rehearing request by IPL.

MISO’s Energy Storage Task Force has been left wondering if it will help shape the RTO’s response to FERC’s sweeping storage participation order.

MISO officials suggested more ways for energy storage devices to participate in the footprint in the future but didn’t commit to any final courses of action.

MISO must fully consider the special attributes of energy storage devices before developing new rules, stakeholders said.

MISO will schedule a “common issues” meeting in response to a request from a group of stakeholders to better define energy storage.
