2021 – Texas' worst energy infrastructure failure, the 2021 Texas power crisis, starts. In February 2021, the state of Texas suffered a major power crisis, which came about during three severe winter storms sweeping across the United States on February 10–11, 13–17 (known as Winter Storm Uri), and 15–20. The storms triggered the worst energy infrastructure failure in Texas state history, leading to shortages of water, food, and heat. More than 4.5 million homes and businesses were left without power, some for several days. At least 246 people were killed directly or indirectly, with some estimates as high as 702 killed as a result of the crisis. State officials, including Republican governor Greg Abbott, initially erroneously blamed the outages on frozen wind turbines and solar panels. Data showed that failure to winterize traditional power sources, principally natural gas infrastructure but also to a lesser extent wind turbines, had caused the grid failure, with a drop in power production from natural gas more than five times greater than that from wind turbines. Texas's power grid has long been separate from the two major national grids to avoid federal oversight, though it is still connected to the other national grids and Mexico's; the limited number of ties made it difficult for the state to import electricity from other states during the crisis. The crisis drew much attention to the state's lack of preparedness for such storms, and to a report from U.S. federal regulators ten years earlier that had warned Texas that its power plants would fail in sufficiently cold conditions. Damages due to the cold wave and winter storm were estimated to be at least $26.5 billion, one of the most expensive disasters in the state's history. According to the Electric Reliability Council of Texas (ERCOT), the Texas power grid was four minutes and 37 seconds away from complete failure when partial grid shutdowns were implemented. During the crisis, some energy firms made billions in profits, while others went bankrupt, due to some firms being able to pass extremely high wholesale prices ($9,000/MWh, typically $50/MWh) on to consumers, while others could not, with this price being allegedly held at the $9,000 cap by ERCOT for two days longer than necessary, creating $16 billion in unnecessary charges.
