Utilities cannot recover prior costs of complying with NERC's critical infrastructure protection standards in ISO-NE, the D.C. Circuit Court said.

The Oregon PUC voted to move ahead with a proposal to amend utility wildfire mitigation plans despite concerns about joint inspections of utilities' poles.

SPP’s Board of Directors and its state regulators will consider a pair of revision requests that did not pass stakeholder muster earlier this month.

An ISO-NE study warned that DERs with older inverters that don't allow them to ride through faults could trip during high solar output and low demand.

PJM updated stakeholders at the OC meeting regarding ongoing discussions with the Illinois EPA over the impacts of the state’s sweeping energy legislation.

SPP stakeholders endorsed the RTO’s latest transmission planning assessment but also withheld approval of a 345-kV, double-circuit project in West Texas.

The ICAP/MIWG discussed rising energy prices, Order 2222 compliance, dynamically scheduling reserves and keeping critical infrastructure out of DR programs.

FERC ordered transmission providers to end the use of static line ratings in evaluating near-term service, saying it will increase utilization of the grid.

PJM is looking to create guidance and requirement language for several manuals related to the implementation of a dynamic line rating system in the RTO.

Reversing course, FERC said PJM did not have to pay an Illinois wind farm $10 million in incremental capacity transfer rights for delivery year 2019/20.
