Texas power grid crises continues: Governor Abbott's energy failures

The Texas Tribune echo report by Mitchell Ferman:

Why Texas's Power Grid Still Has Not Been Fixed? The New Yorker. 

Texas’ grid operator told a power plant to delay repairs ahead of a May heat wave. It was among six that crashed.

Climate change and other factors are shortening the window when aging Texas power plants can make repairs to run at full strength in hot summer months.

On Thursday (May 12th), Texas’ power grid operator told at least one power plant to delay its scheduled repairs and keep operating to help meet demand during hotter-than-expected May weather.

The next day, the plant went offline anyway when some of its equipment stopped working properly, according to energy giant Calpine, which owns the plant. Calpine declined to identify the plant.

By just after 5 p.m. Friday, the Electric Reliability Council of Texas announced that six power plants had gone down unexpectedly and asked Texans to turn up their thermostats to 78 degrees for the weekend and avoid using large appliances during the hottest hours of the day to reduce strain on the power grid.

“We had a scheduled major maintenance outage beginning Friday, May 13, but it was cancelled by ERCOT on May 12,” a Calpine spokesperson said in a statement, adding that May is a “shoulder month” during which power generators historically take power plants offline to do repairs and maintenance during cooler weather.

But this month has been warmer than most Mays of the past decade, leading to higher electricity demand and causing ERCOT to scramble to keep as many plants operating as possible.

Several other power plants broke down Friday and couldn’t produce electricity after agreeing — at ERCOT’s request — to postpone planned maintenance shutdowns, said Michele Richmond, who represents power plants across the state as executive director of the Texas Competitive Power Advocates.

That contradicts what the grid operator said Friday, when an ERCOT spokesperson told The Texas Tribune that maintenance delays did not cause any of the six power plant failures. 

An ERCOT spokesperson said he was checking on whether power plant repair delays requested by ERCOT led to Friday’s plant outages.

ERCOT’s public statement said that “six power generation facilities tripped offline resulting in the loss of approximately 2,900 MW of electricity” — enough to power more than 580,000 homes. “At this time, all reserve generation resources available are operating.”

The brief statement raised more questions than it answered and didn’t address the plants’ locations, whether they were all offline at the same time and why they unexpectedly failed. The weekend passed without major power disruptions, as several of the downed plants returned online by Saturday.

Richmond said ERCOT is “taking a top-down approach” in determining when to tell companies to delay needed repairs and “doesn’t take into account what these complex machines need to make sure they get maintenance done.”

“When you start to tell generators during the season they’re supposed to be doing maintenance that they can’t, then you’re trying to squeeze more out of plants than what is safe and reliable,” she added.

ERCOT approves planned maintenance requests from energy companies months and even years in advance because of the complexity of the work and the need to maintain a minimum level of generation capacity at all times.

Over recent weeks, portable toilets, tents and large cargo containers have been assembled at power plants across Texas for repair crews that allow the facilities to run at full strength during the hot Texas summer.

Dozens of contract workers at many sites erect scaffolding — some even bring in cranes to move heavier equipment — and take apart the plants’ turbines and fix rotating blades. Depending on the scope of the work, a plant can be down for days or weeks.

“Our companies want to be on in the heat of summer, our companies want to be on when customers need us to provide power,” Richmond said. “We also want to do it reliably and safely. Part of reliability of a power plant is taking scheduled maintenance to not only run safely but run at max performance, just like you don’t want to do maintenance on your car when you’re on a cross-country road trip.”

Daniel Cohan, a professor of civil and environmental engineering at Rice University, questioned how the power plants that have been forced to delay maintenance will perform when the worst of the Texas heat arrives this summer.

“I’m concerned with how hard those plants have been run and that maintenance has been deferred to run the grid conservatively,” Cohan said, describing ERCOT’s approach since last year’s freeze of having a larger cushion of power reserve available. “It remains to be seen how much more vulnerable that leaves us to summer outages.”

ERCOT released its forecast for summer electricity demand. The agency expects record-breaking electricity demand of 77,317 megawatts. ERCOT said it has beefed up the amount of reserve power available to the grid and it “is expected to have sufficient installed generating capacity to serve peak demands in the upcoming summer season.”

The Public Utility Commission of Texas, which is in charge of ERCOT, is considering a new rule that could shorten the maintenance season when plants can go offline for repairs. The new rule is based on a provision in Senate Bill 3, the state Legislature’s response to last year’s freeze, when millions of people were without power for days in subfreezing temperatures and hundreds died after a combination of cold weather and skyrocketing energy demand shut down power plants as well as the natural gas facilities that supply them with fuel.

Richmond said the new rule is flawed because it doesn’t outline specific metrics to tell ERCOT when a plant needs maintenance, which she said could be a problem with a shorter maintenance season.

Officials from multiple power companies contacted by the Tribune  questioned whether the rule would give them enough time to make necessary repairs during maintenance season because there are a limited number of qualified repair crews and they travel the country repairing power plants during the milder months of the year. The companies asked not to be identified because power plant outage details have not yet been publicly disclosed by ERCOT.

Cohan said Texans can expect to see hotter temperatures in the coming decades because of climate change, which will put more pressure on the state’s aging power plants.

“You need to do maintenance sometime, and we’ve seen our vulnerability to winter freezes and we know our peaks most often happen in summer heat waves,” Cohan said. “That really leaves it to the fall and spring as the seasons when you need to do maintenance.”

Texas power grid is failed third world greedy technology

Winter Storm Uri plainly showed that the state of Texas developed an electric power system that does not prioritize infrastructure resilience. - Gavin Dillingham, PhD, Program Director, HARC (Houston Advanced Research Center)

“Why couldn’t we get the power?” Morgan said recently. “Because the gas system was not weatherized. And so we had natural gas producers that weren’t producing.”

If another major freeze hits Texas this winter, “the same thing could happen,” Morgan said in an interview.

Winter Storm Uri: Its Impact on Texas and Beyond

Natural gas powers the majority of electricity in Texas, especially during winter. Some power companies say the state’s gas system is not ready for another deep freeze.
MIDLOTHIAN — After last winter’s freeze hamstrung power giant Vistra Corp.’s ability to keep electricity flowing for its millions

of customers, CEO Curt Morgan said he’d never seen anything like it in his 40 years in the energy industry.

During the peak days of the storm, Vistra, Texas’ largest power generator, sent as much energy as it could to power the state’s failing grid, “often at the expense of making money,” he told lawmakers shortly after the storm.

But it wasn’t enough. The state’s grid neared complete collapse, millions lost power for days in subfreezing temperatures and more than 200 people died.

Since the storm, Texas lawmakers have passed legislation aimed at making the grid more resilient during freezing weather. Signing the bill, Gov. Greg Abbott said “everything that needed to be done was done to fix the power grid.”

But Morgan isn’t so sure. His company has spent $50 million this year preparing more than a dozen of its plants for winter.

At the company’s plant in Midlothian, workers have wrapped electric cables with three inches of rubber insulation and built enclosures to help shield valves, pumps and metal pipes.

No matter what Morgan does, though, it won’t be enough to prevent another disaster if there is another severe freeze, he said.

That’s because the state still hasn’t fixed the critical problem that paralyzed his plants: maintaining a sufficient supply of natural gas, Morgan said.

Natural gas slowed to a trickle during the storm, leaving the Midlothian facility and 13 other Vistra power plants that run on gas without enough fuel. The shortage forced Vistra to pay more than $1.5 billion on the spot market for whatever gas was available, costing the company in a matter of days more than twice the amount it usually spends in an entire year. Even then, plants were able to operate at only a fraction of their capacity; the Midlothian facility ran at 30% of full strength during the height of the storm.

“Why couldn’t we get it?” Morgan said recently. “Because the gas system was not weatherized. And so we had natural gas producers that weren’t producing.”

If another major freeze hits Texas this winter, “the same thing could happen,” Morgan said in an interview.

The predicament in Midlothian reflects a glaring shortcoming in Texas’ efforts to prevent a repeat of February, when a combination of freezing temperatures across the state and skyrocketing demand shut down natural gas facilities and power plants, which rely on each other to keep electricity flowing. The cycle of failures sent economic ripples across the country that cost hundreds of billions of dollars.

The power and gas industries say they are working to make their systems more reliable during winter storms, and the Public Utility Commission, the state agency that regulates the state’s power industry, finally acted on recommendations made by federal regulators a decade ago after another severe winter storm.

But energy experts say Texas’ grid remains vulnerable, largely because newly written regulations allowed too much wiggle room for companies to avoid weatherization improvements that can take months or years. More than nine months after February’s storm — which could exceed Hurricane Harvey as the costliest natural disaster in state history — a lack of data from regulators and industry groups makes it impossible to know how many power and gas facilities are properly weatherized.

For millions of Texans, that means there is no assurance that they will have electricity and heat if another major freeze strikes the state.

“If we see a recurrence of the storm we saw last year, people should probably be worried,” said Adrian Shelley, director of the Texas office of Public Citizen, a consumer-advocacy nonprofit group.

The stakes are high, and not just for Texas, the nation’s top energy-producing state. Its winter preparedness affects customers as far away as California and Minnesota and is a test of America’s ability to deal with climate change, which is making weather more extreme, more unpredictable and more deadly.

“Extreme weather events, such as the one in February 2021, are unfortunately becoming more commonplace and the electricity ecosystem needs to come together to plan for and prepare to operate under more extreme, longer duration, and wide area weather events,” Jim Robb, president and CEO of the North American Electric Reliability Corporation, said in a statement.

His organization published a joint report with the Federal Energy Regulatory Commission this month that detailed the failures of both the power and natural gas industries to protect against February’s storm, despite recommendations by federal agencies after a similar disaster in 2011. That storm caused rolling blackouts — but no deaths — across much of the state over three days as then-Gov. 

Rick Perry asked Texans to conserve electricity.*

Although the natural gas industry has blamed electricity generators for the February blackouts — claiming that gas slowed only after power was cut to their facilities — the report said that freezing temperatures were the main cause of a sharp decline in natural gas in Texas and neighboring states in the early days of the storm that triggered a cascade of outages.

“It’s a regulatory problem.”

But federal regulators have little say in how the Texas grid operates.

The main Texas grid is an island, not connected to the country’s two major power grids. This is by design, the result of actions by state leaders decades ago to avoid federal regulation and encourage free-market competition. Multiple state agencies, as well as a nonprofit organization — the Electric Reliability Council of Texas, or ERCOT — govern the grid’s operations, writing rules based on laws passed by state lawmakers.

The lawmakers responded to February's disaster by passing legislation aimed at improving the power system’s preparedness for winter. It established weatherization mandates but left it to state regulators to implement them.

The Public Utility Commission followed with a rule enacting the weatherization requirements. But, the rule allows power plants to request an exception if they document their efforts to comply, explain why they couldn’t and submit a plan to do so later.

The Texas Railroad Commission, which regulates the natural gas industry, is working more slowly. 

A proposal published in September — and expected to be finalized Dec. 1 — lays out a timeline that would identify, map and impose weatherization mandates by early 2023 for gas producers that supply power plants. It also seeks to prevent a repeat of a major paperwork error that resulted in dozens of natural gas providers having their power cut off during February’s rolling blackouts because they failed to declare themselves “critical infrastructure.”

But the proposed rule, which the Railroad Commission said was written to reflect the language in the new state law, allows gas companies to opt out of that classification and avoid having to weatherize their equipment. That infuriated many legislators, despite the fact they’d voted for the law that allowed it after lobbying by the natural gas industry.

The result is that Texas has done “next to nothing” to weatherize its natural gas supply, said Doug Lewin, an Austin-based energy consultant.

“We don’t have a regulatory system in place that holds the industry accountable. That is the problem,” Lewin said. “It's not a technology or engineering problem. It’s a regulatory problem.”

Natural gas fuels a majority of power generation in Texas, especially in winter. At one point during February’s storm, more than half of the state’s natural gas supply was shut down due to power outages, frozen equipment and weather conditions, ERCOT said, adding that at least 20% of the total outages during the week of the storm was due to power plants not getting enough gas.

The natural gas industry has been among the most politically powerful in Texas for generations and has donated generously to the campaigns of governors, lawmakers and the Railroad Commission. That contributes to a culture in which gas companies have escaped strict weatherization mandates, energy experts and consumer advocates say.

The Texas Oil and Gas Association, one of the most prominent energy lobbyist groups in Texas, defended the gas industry’s image in a public relations campaign after the storm. It also has had a heavy hand in deciding who sits on an informal advisory council that lawmakers codified after the storm, intended to ensure energy and electricity operations continue during extreme weather.

The best thing that can be done to avoid a repeat of February is for power companies to get access to larger amounts of stored gas ahead of a storm, he said in an interview this month.

Staples said more than 1,000 facilities — out of more than 250,000 statewide — have filled out paperwork to be added to the list of “critical” facilities that won’t have their power cut off. That’s up from just 60 before the storm, Staples said.

The number will continue to rise after the Railroad Commission enacts its weatherization rule, Staples said. Because not all gas facilities immediately need emergency power during storms, Staples said the Railroad Commission should set up a system prioritizing which get power before others.

He said the industry would be prepared for winter, including having more gas in storage. “If the power is kept on, natural gas will continue at a reasonable level,” Staples said.

Oncor, Texas’ largest electricity transmission and distribution company, which delivers power to 3.8 million homes and businesses, said since the February storm it has received 1,061 forms from gas companies declaring their infrastructure as critical, a sign those companies are likely to be weatherized and prepared to operate during a grid emergency. AEP Texas and CenterPoint Energy, which together service more than 3.6 million Texas households and businesses, said they have received another 278 forms from gas companies registering their facilities as critical.

Several of Texas’ largest natural gas producers, including XTO Energy and Apache Corp., did not return calls or emails seeking comment on their weatherization efforts. Spokespeople for BP and Devon Energy declined to comment.

And the Railroad Commission said it did not know how many natural gas companies are actually prepared for winter. An agency spokesperson said ERCOT would have this information.

An ERCOT spokesperson declined to comment.

As the Railroad Commission works on its weatherization rule, electricity companies — including Oncor, AEP Texas, CenterPoint and Texas-New Mexico Power Company — have already begun criticizing the proposal. 

The companies filed a comment with the commission arguing that the proposed rule was too vague and “does not provide information electric utilities will need in order to efficiently and effectively incorporate natural gas facilities into their respective” emergency plans.

Virginia Palacios, executive director of Commission Shift, an organization that researches the Railroad Commission’s ties to the oil and gas industry, said the long process of creating new weatherization rules has prevented Texas from preparing for this winter.

“We are not going to have any assurances that operators are weatherizing for this winter,” Palacios said. “And probably not for the next one.”
