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.

Coal plant retirements have not caused a shortage of black start resources, but grid operators should consider expanded testing, FERC and NERC said.

FERC approved the dissolution of the SPP Regional Entity and the transfer of its members to the Midwest Reliability Organization and SERC Reliability Corp.

FERC approved rules to prevent malware from infecting “low impact” computer systems through devices such as laptops and thumb drives.
