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.

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

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

Although FERC has required almost all new generating units to provide primary frequency response (PFR), PJM stakeholders are strongly opposing any move by the RTO to require existing units to follow suit.

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

MISO challenged a 2017 NERC assessment that found two areas in the RTO would challenges during a disruption of natural gas delivery.

SPP said that its Board of Directors has created a Holistic Integrated Tariff Team (HITT) to take an all-encompassing look at the different challenges facing the RTO.

NERC said that it has appointed Western Electricity Coordinating Council (WECC) chief Jim Robb as its new president and CEO, effective April 9.
