Nearly 3.4 million Texans are still without power on Wednesday afternoon and are struggling to stay warm as temperatures hover around freezing in much of the state.
How did this happen?
Texas is the only state in the nation with its own power grid, which is managed by Electric Reliability Council of Texas. When a winter storm moved across the state earlier this week, the demand of energy skyrocketed because Texans were at home trying to stay warm. The demand was so high that the grid could not generate enough electricity.
What caused the blackouts?
Electricity is generated from a combination of natural gas, coal power, wind power, and nuclear power. Texas power plants are built for extreme summer conditions since extreme winter weather is rare in much of the state. Equipment and power plants couldn't function because of the freezing weather. Other factors contributed to generators being off line.
ERCOT also started rolling blackouts on Monday to prevent the power grid from becoming overloaded.
How is this effecting residents?
Because the blackouts are unpredictable, some Texans have been without electricity for days at a time.
Texans say they are angry and feel like they're abandoned.
The blackouts are also causing issues for area water utilities and water treatment plants. Residents in Houston, Austin, Fort Worth, Corpus Christi, and other cities are being asked to boil their water before consuming to make sure their water is safe.
Power outages have also caused grocery stores to close.
When will the power come back on?
Unfortunately, no one knows. ERCOT is still working to get power plants and generators working. The agency doesn't have a deadline for when that might be.
