The Electric Reliability Council of Texas (ERCOT) in freshly revealed data on March 4 reported that the Texas grid suffered 1,796 generating or energy storage outages or derates as winter storm Uri bore down on the state in mid-February.  The grid operator made the list public in a letter it sent to lawmakers in the […]

Board members of the Electric Reliability Council of Texas (ERCOT), the entity that operates and manages the electricity grid that covers much of Texas, voted late on March 3 to fire ERCOT CEO Bill Magness. The move comes as state and federal officials continue to investigate the actions of the grid operator that led to […]

The chairwoman of the Public Utility Commission (PUC) of Texas has resigned, stepping down after the state’s lieutenant governor earlier on March 1 called for her resignation, along with that of the CEO of the state’s power grid operator. DeAnn Walker, the PUC chair, in her resignation letter Monday to Gov. Greg Abbott, defended her […]

The group considered Texas’ oldest and largest electricity cooperative has filed for Chapter 11 bankruptcy protection, saying it can’t pay money wanted by the state’s grid operator in connection with power outages during a major winter storm that hit in February. Brazos Electric Power Cooperative filed its bankruptcy petition March 1 in the U.S. Bankruptcy […]

Five board members of the Electric Reliability Council of Texas (ERCOT), the state’s power grid operator, on Feb. 23 announced they would resign their posts, just days after extreme winter weather left more than 4 million Texas electricity customers without power for several days. Sally Talberg, chairwoman of ERCOT, is among those resigning. All those […]

The fallout from the severe weather that crippled the power grid in Texas and other states over the past week continues, as officials grapple with what went wrong and who should be held accountable for an energy emergency that left millions without electricity. Texas Attorney General Ken Paxton on Feb. 19 said his office would […]

It will be some time before we know every detail that aligned to cause the tremendous number of sustained power outages in Texas, or the spiking power prices across all markets in the central states. Some things we do know. Some natural gas supply was frozen in. Some wind turbines froze up, and ice damaged some […]

After three harrowing days during which the Texas grid veered precipitously toward system collapse, the Electric Reliability Council of Texas (ERCOT) has begun directing transmission operators to cease rotating blackouts.  The grid recorded a gradual increase of restored generation capacity through Feb. 17 and overnight on Feb. 18. Early on Thursday, a little more than […]

Texas Gov. Greg Abbott has said reforming the Electric Reliability Council of Texas (ERCOT) is an emergency item for state legislators in the current session, as power outages continue across the state for another day due to record cold temperatures as part of a massive winter storm. The governor on Feb. 16 said he wants […]

Historically frigid temperatures across Texas forced 34 GW of generation—across all fuel types—off the Electric Reliability Council of Texas (ERCOT) system, prompting the grid operator to initiate rotating outages starting at 1:25 a.m. CST on Feb. 15. ERCOT said it expects outages will likely last at least through Feb. 16. This article has been updated […]

A quest for reliability and flexibility is driving significant interest in hybrid and co-located resources, but their widespread integration could hinge on how they are defined and valued in wholesale

The Texas power market made headlines in August 2019 when wholesale prices for electricity repeatedly spiked close to and even hit the $9,000-per-megawatt-hour (MWh) cap. This August, average hourly prices peaked at “just” $1,700 per MWh, the afternoon of Aug. 15. There were many reasons for the reduced price volatility in Texas this year. First, […]

A new report from two groups that study energy policy supports the establishment of a fully competitive regional electricity market in the U.S. Southeast, something already being discussed by at least two of the region’s largest utilities. The analysis published August 25 from San Francisco, California-based Energy Innovation, and Boulder, Colorado-based Vibrant Clean Energy (VCE), […]

It’s an article of faith in large parts of the U.S.—at least among power industry people—that organized and Federal Energy Regulatory Commission (FERC)–regulated “merchant” interstate power markets are the best way to ensure a sufficient supply of electricity, as well as to ensure fair and equitable prices for ratepayers. On that basis, large areas of […]

It’s peak season for the U.S. power industry. While actual dates may vary from one utility to another, generally the summer peak period spans from Memorial Day (May 25 this year) to Labor Day (Sept. 7)

Despite uncertainties posed by the COVID-19 pandemic, the Electric Reliability Council of Texas (ERCOT) again expects to shatter its peak demand record this summer. Factoring in changes to its generation profile, extreme weather, and low wind output, the grid operator expects energy alerts are still possible.  ERCOT’s forward-looking projections for capacity, demand, and reserves are murkier, […]

Despite adding 513 MW of new capacity this year alone, the Electric Reliability Council of Texas (ERCOT) expects tight grid conditions this summer, and it warned it could declare an energy emergency depending on a combination of factors. Citing its newly released preliminary Seasonal Assessment of Resource Adequacy (SARA) assessment for the summer season (June–September), […]

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 […]
