Power outages in the United States by state in February 2021

Winter storm Uri has brought unusually cold weather and power outages to many parts of the United States in February 2021, with Texas particularly affected. Low temperatures have fueled greater electricity demand for heating, while also being of trouble to multiple kinds of generating capacity. Thermal power stations not fitted with cold-withstanding equipment had to be shut-off as the water needed to run natural gas, coal, and nuclear power plants froze. Additionally, wind turbines in the state had not been provided with anti-freeze coatings, leading to some turbines having to be turned off. Limited natural gas supply and resulting lower pressure were counted among the main reasons for why electricity had not come back in full even two days after the storm hit. On February 16, over four million Texan customers suffered a blackout. Two days later, this figure stood at 687,100.
