What You'll Learn
Power outages caused by severe winter weather
One of the main challenges in restoring power was the instability of the state electric grid. ERCOT, the state electric grid operator, struggled to bring enough power generation online to rotate outages among customers. This meant that many residents and businesses in Cedar Hill went without power for extended periods. The city continuously pushed the power company, Oncor, for better restoration estimates and worked to address the various issues caused by the outages.
To cope with the lack of power, residents were advised to lower their thermostats to at least 68 degrees and wear additional layers of clothing. They were also instructed to unplug electronic devices and turn off lights when not in use to minimize energy consumption. Lowering the water heater temperature was also recommended, as it can account for a significant portion of energy usage.
The power outages had a significant impact on the community. The 9-1-1 communications center experienced a high volume of calls related to the power outages. The Zula B. Wylie Public Library remained open 24/7 to provide a warm space for residents without power, offering coffee and requiring masks and social distancing. Hazardous road conditions led to the closure of city offices and facilities, including the Cedar Hill Government Center and the Alan E. Sims Recreation Center.
In addition to power outages, the severe winter weather caused plumbing issues for many residents. Frozen pipes were a common problem, and the city provided instructions on how to thaw pipes using electric heating pads, hair dryers, or portable space heaters. Residents with burst or broken pipes were instructed to call for emergency assistance to shut off their water. The city also addressed issues such as water main breaks and delayed trash services due to hazardous road conditions.
The power outages in Cedar Hill, TN, caused by severe winter weather, had widespread impacts on the community. The instability of the state electric grid prolonged the outages, and the city worked diligently to address the various consequences. Residents coped with the lack of power by conserving energy and seeking warmth in public spaces. The city also provided guidance and assistance for plumbing issues and other challenges arising from the power outages and severe weather conditions.

ERCOT unable to predict when the grid will stabilize
In February and March 2021, the Electric Reliability Council of Texas (ERCOT), which manages the state's power grid, was unable to predict when grid conditions would stabilize. ERCOT urged customers to prepare for continued, extended outages. The council also asked customers to prioritize their safety and that of their loved ones and neighbors.
Oncor, which sent out a news release regarding the situation, said that despite rotating some outages overnight, poor grid conditions had continued to prevent them and other utilities from rotating or rolling the entirety of these outages. This led to extended periods without power for many customers.
Dan Woodfin, Senior Director of System Operations at ERCOT, expressed optimism about reducing the number of controlled outages, stating, "The number of controlled outages we have to do remains high. We are optimistic that we will be able to reduce the number throughout the day."
ERCOT attributed the grid instability to weather conditions and generation outages, which brought the load shed to 18,500 MW. The council assured customers that the return of generators and an increase in renewable output would lead to increased customer restoration.
While ERCOT could not provide a timeline for stabilization, they assured that power restoration was ongoing, with over 500,000 households having their power restored on Monday.

Emergency Operations Center activated to assist
The City of Cedar Hill has activated its Emergency Operations Center to monitor and assist with the impacts of severe winter weather and associated power outages. The center will coordinate responses to issues such as plumbing problems, water main breaks, delayed trash services, and hazardous road conditions.
The power outages in Cedar Hill, TN, are due to the severe winter weather, and the state electric grid operator, ERCOT, is unable to predict when grid conditions will stabilize. This has led to ongoing outages for many customers, and the city is pushing Oncor for better restoration ETAs.
The Emergency Operations Center will play a crucial role in managing the situation and providing support to residents. With the 9-1-1 communications center experiencing a high volume of calls related to power outages, the city is also directing residents to contact the Oncor outage system directly for any queries.
To assist residents without power, the Zula B. Wylie Public Library on 225 Cedar Street is open 24/7 for people to warm up. Masks and social distancing are required inside, and coffee is provided. Residents are advised to drive with caution if travelling to the library, and pets cannot be accommodated due to limited space, although limited accommodations are available at the Tri-City Animal Shelter.
The city is also providing guidance to residents on how to manage power and water issues. This includes recommendations to lower thermostats, wear additional clothing, and minimize energy usage. If residents experience burst or broken pipes, they are advised to call 9-1-1 for an emergency water shut-off and then follow guidance from the American Red Cross to thaw their pipes.

Residents advised to conserve energy
Due to hazardous road conditions caused by winter weather, the City of Cedar Hill is currently experiencing a power outage. The Zula B. Wylie Public Library is open 24/7 to residents without power.
To help conserve energy and natural gas, residents are advised to lower their water heater temperature to 120 degrees, unplug electronic devices, and turn off lights that are not in use. Showering accounts for about 40% of a home's hot water use, so reducing shower time and avoiding baths can also help. Residents should refrain from using large appliances such as washers, dryers, ovens, and dishwashers. If using the oven, limit opening the door to prevent wasted energy. Keep the fireplace damper closed unless a fire is burning, as leaving it open allows warm air to escape up the chimney.
Additionally, it is important to protect natural gas meters. While they are weather-proof, removing snow and ice with a broom or brush can help ensure they continue to work smoothly. Never use an oven or gas stovetop to heat your home, and minimize the risk of frozen pipes by leaving faucets running at a trickle and cabinets open.
By following these measures, residents can help conserve electricity and natural gas, ensuring a steady power supply during this challenging winter weather.
