Last weekend, a major winter weather system characterized by extreme cold spread across much of the central United States, disrupting energy systems and causing serious health and safety issues, particularly in Texas. At the same time that the cold weather increased energy demand, it also affected energy supply, causing intense and widespread energy market disruptions. Notably, electricity deliveries have been disrupted in the parts of Texas served by the Electric Reliability Council of Texas (ERCOT) as a result of various issues related to plant operations.
