Thermal energy storage powered by renewables could be a flexible, cost-effective way to decarbonize heavy industry in the U.S., according to a new report from the Renewable Thermal Collaborative and Center for Climate and Energy Solutions.

Clean energy groups in MISO have told FERC it should rethink its support of a ban on renewable energy in MISO’s ancillary service market because the commission didn’t consider hybrid resources.

FERC ruled it’s appropriate for MISO to continue to preclude renewable resources from providing ancillary services in its markets, countering a solar trade group’s complaint.

MISO has FERC’s go-ahead to bar its renewable energy resources from supplying ramping reserves.

ERCOT stakeholders endorsed the charter and leadership for a task force that will report to the Technical Advisory Committee and provide recommendations on real-time co-optimization and energy storage resources’ state of charge.

FERC has approved a $21 million settlement over an Arkansas steel mill’s yearslong failure to reduce load as a registered demand response resource in MISO.

PJM's Market Implementation Committee endorsed one of several packages to create new rules for generators with co-located load and rejected four proposals revising how generators providing reactive power service are compensated.

PJM's Market Implementation Committee discussed potential changes to reactive power compensation and the progress of developing new market clearing engine software.

NYISO has identified a software issue that potentially constitutes a market problem and says it will confidentially investigate the impact.

ERCOT staff said it faces a tight timeline to add a new ancillary service by Dec. 1, 2024, as required by the recent Texas legislative session.
