The ability of some companies that generate the power has been frozen. This includes the natural gas & coal generators,” Abbott wrote, adding that ERCOT and the Public Utility Commission of Texas are working to get power back online and will give priority to residential consumers.

Frozen wind turbines and limited gas supplies have hampered the ability to generate enough power, according to a statement from ERCOT.

People in Houston, the fourth most populous city in the US, may be in the dark into Tuesday, according to the Mayor Sylvester Turner.

As of Monday afternoon, there were 1.2 million CenterPoint customers without power, including the city of Houston and the Houston region, Turner said, a number that he said could increase as the weather gets colder in the evening.

“I just want to be very upfront with the people of the city: If you are without power right now, it is very conceivable that you could be without power throughout the rest of today and possibly even going into tomorrow,” Turner said.

Rotating blackouts occur when power companies cut off electricity to residential neighborhoods and small businesses, typically for 10 to 45 minutes before being rotated to another location, ERCOT said. Traffic lights and infrastructure may also lose power during these blackouts.

Oncor, an energy company serving parts of north Texas including Dallas, tweeted Monday that “our expected outage length of 15 to 45 minutes has been significantly extended. Outages due to this electric emergency could last for hours & we ask you to be prepared.”
California sometimes uses rolling blackouts during heat waves, but extremely cold weather forced the action in Texas, where the winter storm has already knocked out power to more than 3.4 million customers, according to Poweroutage.us, a website that tracks power outages across the US.

Snow fell across much of Texas, including more than 10 inches in San Angelo, its snowiest day on record, and 4 inches in Dallas to tie for its seventh snowiest day on record.

The entire state was below freezing on Monday, with temperature ranging from 25 degrees in Brownsville in the south to 15 degrees below zero in the Panhandle. A trace of snow was reported in Brownsville, only the third time since 1898 that snow was reported in the city in the state’s southernmost point along the US-Mexico border.

Temperatures in the high teens were predicted for Dallas on Monday, while Houston was expecting a high temperature in the mid-20s. Below-freezing temperatures are expected in Dallas through Thursday.

The city of Houston recommended people conserve energy by turning down thermostats to 68 degrees Fahrenheit, unplugging nonessential lights and appliances, opening curtains in the day to allow sunlight and closing curtains at night to reduce heat loss.

The rolling blackouts caused several police facilities to operate on emergency generators, said Houston Police Department Chief Art Acevedo.

“Please reduce the load on the electric grid by keeping use to a minimum,” Acevedo tweeted Monday.

The city of Galveston estimated that 90-95% of households were without power Monday because of the increased demand for electricity.

The largest oil refinery in the US in Port Arthur, Texas, is shutting down due to the freezing weather.

The refinery’s operator, Motiva Enterprises, said in a statement that “unprecedented freezing temperatures necessitated safely and methodically shutting down our Port Arthur Manufacturing Complex.”

One family’s difficult day without power

In Katy, Texas, just west of Houston, Tricia Lydick said her home has been without power since 5:30 a.m. Monday with no sign of returning anytime soon.

Lydick lives with her brother, Michael Towns, and their mother, Ann Towns, who are both disabled. Her mother has chronic obstructive pulmonary disease and requires oxygen around-the-clock. The family has extra tanks with enough to last 12 hours.

But her mother uses a CPAP machine to help her breathe while sleeping and no electricity makes that impossible for her, Lydick told CNN.

“Four hours isn’t a huge deal but I don’t want it to get to where we start running out of oxygen for Mom,” Lydick said. “We are native Texans and haven’t ever had temps like this before.”

She’s been trying to contact her power company on the phone but to no avail. The family is using blanket and jackets to keep warm in the house.

“Since all the roads are iced over, it’s way more difficult for the lines to be fixed,” she said. “I totally get that.”

If the power outages last longer than anticipated, Lydick said her first thought would be to take her mom to the hospital.

“But the roads are iced over, so I don’t know how I could,” she said. “She can’t live without her oxygen.”

‘Record-breaking electric demand’

The ERCOT ordered the rolling outages around 1:30 a.m. CT (2:30 ET) Monday. ERCOT set a new winter peak demand for electricity between 6-7 p.m. Sunday, topping the old record from January 2018, ERCOT said in a tweet.

“We are experiencing record-breaking electric demand due to the extreme cold temperatures that have gripped Texas,” ERCOT President and CEO Bill Magness said in a news release. “At the same time, we are dealing with higher-than-normal generation outages due to frozen wind turbines and limited natural gas supplies available to generating units.”

Entergy Texas, which provides power to approximately 461,000 customers across 27 counties in the state, according to its website, said it started the rolling outages on Monday.

“We apologize for the inconvenience these outages may cause, but we have an unusual situation right now driven by extreme weather conditions. We are working to respond and restore power as soon as it is safely possible,” said Stuart Barrett, vice president of customer service.

“While our crews worked to prepare for this storm, a loss of generation combined with the peak load has caused a strain on the system. As a result, we are short of the power needed to meet our customers’ demands across southeast Texas.”

Southwest Power Pool, which manages electrical grid operations in North Texas and 16 other states, said it will have rolling blackouts.

“In our history as a grid operator, this is an unprecedented event and marks the first time SPP has ever had to call for controlled interruptions of service,” said Lanny Nickell, SPP’s executive vice president and CEO, in a news release.

SPP told transmission operators to reduce demand by the amount needed to prevent further uncontrolled outages, according to the release.

CNN’s Jeremy Grisham, Kay Jones, Alison Kosik, Gregory Lemos, Tyler Mauldin and Artemis Moshtaghian contributed to this report.
