World Why the Texas power grid is struggling to cope with the extreme cold
ERCOT Power Outage Map, Updates As Texas Winter Storm Leaves 1.8 Million Without Power
Energy companies have been directed by the Electric Reliability Council of Texas to rotate power outages.Power Outage US reports that nearly two million Texans are without power as numerous energy providers implement controlled outages to control the flow of power. Texas is being hit by a winter storm and facing freezing temperatures and heavy snowfall.
Winter Storm Uri chilled large areas of the western, central, and southern US over the weekend, straining the power grid in some places so badly that millions of Americans have had to go without power in temperatures below freezing.
Theon Monday reported that 150 million Americans were under various winter storm warnings, with heavy snow and ice still likely to sweep from the Southern Plains, to the Ohio Valley, to the Northeast.

Blame the wind? In Texas, fossil fuels have actually played a larger role in leaving millions without power
Freezing cold temperatures have caused severe power outages in Texas. A majority of lost generation has been from fossil fuels, not wind. But the main factor is not the source of electricity, but the extreme weather. Visit the Business section of Insider for more stories. It's a popular claim and a powerful image, attracting the attention of conservatives and headline writers of all political persuasions: frozen wind turbines are to blame for Texans losing power and icicles forming their homes during this week's shocking cold spell.
Texans, however, may be shivering more than others, with some of the coldest temperatures in 30 years, and some of the biggest power grid problems. More thanhad lost power as of Tuesday morning when temperatures dipped as low as 4 degrees Fahrenheit — lower than Anchorage, Alaska — in cities like Dallas. Flights were canceled out of . On Sunday, President Joe Biden approved a declaration for Texas following a request from Gov. Greg Abbott.
For residents of the Lone Star State, the problem stems from both a record spike in electricity demand in a place that rarely gets this cold, as well as an unexpected drop in the supply of energy fromsources besieged by cold and ice.
3 ways Texas could avoid another electricity crisis
The answer is not more fossil fuel power plants.When the cold front hit over the weekend, electricity use soared to heat buildings, but the grid couldn’t keep up with demand. Natural gas plants, which supply the majority of the state’s electricity, were not equipped to operate at such low temperatures. Despite widespread false claims spread on Fox News that frozen wind turbines were solely to blame for the blackout, failures at these gas plants are the main cause of the crisis, a spokesperson for ERCOT told Bloomberg.
This combination of shortfalls has forced power grid operators to conduct rolling blackouts, where power is shut off to different areas for a limited period of time. Local utilities are asking customers to conserve power and set their thermostats lower. For some customers, these blackouts aren’t rolling, instead stretching on for an unknown duration.

Throughout the state, theand 135 public warming centers have opened up to give people a respite from the frigid weather, although Covid-19 precautions remain in effect.
Scientists are divided over whether climate change is fueling extreme cold events
Is the cold wave that froze Texas this week a unique event or a sign of what’s to come?States like Texas with milder winters were caught off guard by the chill, which led to a massive spike in energy demand and a huge drop in available electricity as the infrastructure around natural gas, coal, nuclear, and wind energy froze up. Tuesday was the coldest day in North Texas in 72 years, with the Dallas-Fort Worth area reaching a record low temperature of minus 2 degrees Fahrenheit this week.
Texas’s grid crisis is a stark reminder that extreme weather events like Uri remains a threat to energy infrastructure across the country. There are, however, some unique factors in Texas that have put the state in such a precarious position. And with more frigid weather in store this week, Texans can’t come in from the cold just yet.
Why the extreme cold has the Texas power grid shaking in its boots
Unlike other states, Texas operates its own internal power grid that serves much of the state. Managed by the nonprofit Electric Reliability Council of Texas, or, the grid provides 90 percent of the state’s electricity and serves 26 million customers.
It draws on a diverse range of power sources in a competitive market. Thein Texas is natural gas, followed by wind and solar, coal, then nuclear. The state is the largest oil, natural gas, and wind energy producer in the US.
The sudden cold snap this weekend put the state’s ample resources to the test, with demand reaching a record high peak for the winter, more than 69,000 megawatts. That’s 3,200 MW higher than the previous record set in 2018.
Fact Check: Did Biden Rescind Trump Order Prohibiting Chinese Influence on US Power Grid?
With power failures causing devastation across Texas, many people began questioning the integrity of the United States' energy supply. Some accused Biden of handing over the country's power grid to the Chinese in an executive order signed in January.Some critics of President Joe Biden are pointing to a section in one of his January executive orders that address a President Donald Trump-era bulk-power system security policy.
— ERCOT (@ERCOT_ISO) set a new winter peak demand record this evening, reaching 69,150 MW between 6 and 7 p.m. This is more than 3,200 MW higher than the previous winter peak set back in January 2018. Thanks to everyone who has been conserving today. We appreciate it!
As demand reached new heights, the supply of electricity fell drastically in the past few days, far below what operators expected. Ordinarily, ERCOT plans for winter to be much warmer and anticipates a lower energy demand. Power providers often schedule downtime and maintenance during the winter months to prepare for the massive annual surge in electricity demand in the hot Texas summer. The state’s ample wind and solar energy resources are also diminished in the winter, so ERCOT doesn’t depend on them to meet much of the demand they anticipate.
However, the cold itself posed a direct challenge to the power sources that the state was counting on.iced up. Coal piles froze.
The biggest shortfall in energy production stemmed from natural gas.were blocked with ice or their compressors lost power. Much of the gas that was available was prioritized for heating homes and businesses rather than generating electricity. That’s helpful for people who use gas for heating but less so for those who use electric furnaces.
Much of Texas has power back — but it still faces water and food shortages
Millions of Texans are under “boil water” orders after a winter storm.On Friday, the Electric Reliability Council of Texas (ERCOT), which oversees much of the state’s power grid, ended emergency conditions and returned to normal operation. Previously, soaring demand for power and frozen natural gas pipelines, among other factors, meant that millions of Texas residents were without power and facing widespread rolling blackouts in freezing weather.

Wholesale natural gas prices, meanwhile, shot up as much as. According to , electricity prices in northern Texas jumped to $300 per megawatt-hour, up from the average this month of $18 per megawatt-hour.
In total, aboutin Texas went offline during the winter blast, more than 40 percent of peak winter demand. So even with a diverse range of energy sources, Texas was left scrounging for electrons in the bitter cold.
Many parts of the country suffer outages in extreme weather, but everything is bigger in Texas
The power grid is a complicated construct, but it becomes unstable when there is more energy demand than supply, which forces drastic actions like deliberate blackouts.
One question many Texans are asking is whether ERCOT should have seen a scenario like this coming and done more to prepare. ERCOT has historically been more worried about meeting peak summer demand, which can topas hundreds of thousands of air conditioners switch on to cool during the summer heat.
However, Texas has faced cold snaps before, and the current winter storm was forecast days in advance.
ERCOT did do some modeling and planning ahead of this winter, but they used past winters as their benchmarks, which aren’t much help when the cold dips to record-breaking lows. “We studied a range of potential risks under both normal and extreme conditions, and believe there is sufficient generation to adequately serve our customers,” said Peter Warnken, manager of resource adequacy at ERCOT, in a reportin Texas.
The state of Texas should cover residents' huge energy bills from last week's power outages, the mayor of Houston said
Texas should pay residents' huge energy bills from last week's storms, according to US officials. Texans have reportedly been charged up to $US16,000 for electricity, after its wholesale price surged 10,000%. Houston mayor Sylvester Turner, Texas Rep. Michael McCaul, and Sen. Ted Cruz said Texans shouldn't pay the price. Visit the Business section of Insider for more stories. US officials are calling on the state of Texas to pay residents' hefty utility bills, following winter-storm power outages that left millions without electricity or clean water.
The state was only expecting to lose about 8,600 megawatts in power generation over the winter, with a peak demand of roughly 58,000 megawatts. That forecast was far off the mark from the 34,000 megawatts that went offline and the peak of 69,000 megawatts in the recent winter storm.
Part of the problem may also be Texas’s go-it-alone approach to its electricity. “The Texas power grid is really an island,” said, an associate professor of environmental engineering at Rice University who has done modeling research on the state’s power systems. “Whatever happens in Texas stays in Texas.” While there are some interconnections between Texas and neighboring states, those power lines aren’t adequate to draw the power it would need to cope with such a massive shortfall.
has helped cushion the blow of extreme cold in past winters, but it’s not clear that there would be much power available for Texans to buy from other states right now, as many are also coping with their own soaring energy demands and supply shortfalls.
The Texas blackouts may also be a symptom of a lack of proper upkeep. “The ERCOT grid has collapsed in exactly the same manner as the old Soviet Union,” Ed Hirs, an energy fellow in the Department of Economics at the University of Houston, told the“It limped along on underinvestment and neglect until it finally broke under predictable circumstances.”
And Texas isn’t the only part of the country that has struggled to stay warm in chilly winters. In 2019, a winter storm swept across the, with spikes in electricity demand and sudden drops in natural gas production that forced people to ration heat and reduce power use.
On the other end of the spectrum,last summer as energy demand surged amid . California utilities also shut off power to customers to when high winds picked up amid dry weather.
These events triggered by weather extremes can overwhelm energy systems, even for those that face such spikes and dips on a regular basis. It’s too reductive to blame any individual factor like intermittent renewable energy, fossil fuel generator shutdowns, decrepit infrastructure, or inadequate planning, though such events often become a.
Rather, it’s a combination of multiple cascading failures that leaves millions of people in the dark. The hope now is that the power outages in Texas will provide important lessons and help avoid similar problems in the future. “I think this is an event that people are going to be looking back at for years,” Cohan said.
Will Texas Republicans Pay a Price for the Blackouts? .
The state’s energy disaster is over. The fallout is just beginning.Assessing political liability for a natural disaster is tricky. Texas is still a Republican state. Despite Democrats’ progress in recent elections, the power-grid collapse of 2021 is not likely to be the final push that turns the Lone Star State blue. But the specific circumstances of last week’s catastrophe make predicting voter behavior more difficult than it might normally be. Political experts I spoke with were confident about at least one thing: The disaster will almost certainly inspire more Democrats to challenge the state’s ruling party.
