NERC offered an upbeat report on the long-term health of the nation’s grid, celebrating results from its interconnection-wide frequency response studies.

ERCOT is repeating many of the preparations it took before last summer as it looks ahead to even tighter reserve margins in 2019.

Texas PUC Chair DeAnn Walker urged ERCOT to gain a “better sense” of the distributed resources and self-generation that could be affecting its system.

ERCOT said Tuesday that it confronts a historically low 8.1% planning reserve margin next summer in the face of continued high electricity demand from oil and gas producers in West Texas and the cancellation of several generation projects.

ERCOT’s Technical Advisory Committee endorsed a staff suggestion to increase by 50% the boundary thresholds used to project future loads in Far West Texas.

ERCOT CEO Bill Magness says utility-scale solar “is the next big thing coming at us from the supply side,” giving the ISO one more challenge to consider.

The Department of Energy convened to gather information for the department’s 2019 electric transmission congestion study.

ERCOT set a pair of demand records, establishing new marks for wind power and November monthly demand as temperatures dipped in much of Texas.

FERC approved NERC’s revised geomagnetic disturbance reliability standard, which requires grid operators to collect data and imposes deadlines for actions.

FERC moved to apply its proposed new methodology for calculating transmission owners’ return on equity rates to dockets in MISO and the South.
