How many RCs there will be in the Western Interconnection, and who they are, should come into better focus on Sept. 4, said WECC CEO Melanie Frye.

The NERC Board of Trustees approved Wisconsin Public Service Corp.’s and Upper Michigan Energy Resources’ requests to move to ReliabilityFirst from MRO.

FERC ordered expanded reporting of cybersecurity incidents, saying attempts not currently reported could lead to bigger, more successful attacks.

The SPP Regional Entity will cease all compliance monitoring and enforcement activities at the close of business Friday.

The bulk power system showed improved ability to rebound from severe storms last year while continuing to improve on most other reliability metrics, NERC said.

CAISO will make permanent a once-temporary practice of boosting its power reserves to account for utility-scale solar tripping offline because of inverters problem, something NERC has identified as a major reliability issue.

FERC gave final approval to NERC reliability standards on training requirements and the coordination of protection systems.

NERC said Wednesday that its annual summer reliability assessment indicates ERCOT and CAISO will face operational challenges and potential reliability concerns this summer, thanks to the two ISOs’ respective loss of baseload generation and lack of fuel assurance.

FERC proposed to approve a revised reliability standard on geomagnetic disturbances but directed NERC to also require mitigation of vulnerabilities to localized events.

FERC should let RTO stakeholder processes work and not issue broad and costly new mandates on grid resilience, commenters told the commission.
