Significant and rapid changes that are reshaping North America’s power sector will likely leave Texas and Ontario, Canada, with supply shortfalls over the next decade, and energy deficiencies could also occur during off-peak conditions in the Midcontinent Independent System Operator (MISO) area and the Western Electricity Coordinating Council (WECC) region, the North American Electric Reliability […]

COMMENTARY Texas has the most wind capacity of any state, generating about 16% of its electricity from wind. In August, as temperatures rose above 100F and consumers increased their use of air conditioning, Texas’ grid operators struggled to meet the record demand for electricity. Many of the wind turbines could not operate because the wind […]

What does the 21st century power market look like? That is the question the European Union (EU) is attempting to answer with the new electricity regulation and revised electricity directive passed at the end

The percentage of coal-fired generation in the U.S. electricity mix will continue to decline, the Energy Information Administration (EIA) said May 9, with gas-fired generation accounting for at least 40% of the nation’s power this summer and output from renewables continuing to rise. EIA’s latest Short-Term Energy Outlook (STEO) said coal-fired units will produce only […]

The Electric Reliability Council of Texas (ERCOT) has issued a fresh warning that continued “above-normal” growth in electric demand could require it to enter Energy Emergency Alert (EEA) status to maintain system reliability this summer.  As it released its final Seasonal Assessment of Resource Adequacy (SARA) for the upcoming summer season (June to September), a preliminary […]

Grappling with a historically low planning reserve margin of 7.4%, owing to a mass of coal plant closures, the Electric Reliability Council of Texas (ERCOT) is forecasting record electric use this summer and warns it could issue energy alerts at “various times.”  ERCOT said its March 5–released final Seasonal Assessment of Resource Adequacy (SARA) for […]

California and Texas—two regions where summer reliability concerns were forecast earlier this year—are suffering extreme temperatures and are scrambling to relieve stress on the grid. The California Independent System Operator (CAISO)—the grid operator that serves about 80% of California—on July 24 and 25 issued statewide Flex Alerts, calling for voluntary electricity conservation during peak afternoon […]

Electricity is produced by a variety of generating units, each with different lead times and costs to be readied for service, and production costs once brought online. Because electricity is a commodity that

Higher-than-average temperatures forecast for much of the U.S. this summer won’t affect reliability in most regions, though concerns remain for Texas and Southern California, according to the Federal Energy Regulatory Commission (FERC). Presenting the “Summer 2018 Energy Market and Reliability Assessment,” on May 17,  FERC staff said that most entities that are part of the […]

The Electric Reliability Council of Texas (ERCOT) on April 30 updated its summer 2018 planning reserve margin to 11% based on resource updates, but it warned that the regional grid serving most of Texas could still suffer rotating outages under extreme conditions. In its final Seasonal Assessment of Resource Adequacy (SARA) report for the upcoming […]
