Why the power grid failed in Texas and beyond

The power outages tormenting Texas in uncharacteristically arctic temperatures are exposing weaknesses in an electricity system designed when the weather’s seasonal shifts were more consistent and predictable — conditions that most experts believe no longer exist. The gap between the winter and summer supply reflects power plants going offline for maintenance during months when demand typically is less intense and there’s not as much energy coming from wind and solar sources. None of them were adequately weatherized or prepared for a full realm of weather and conditions.” The staggering imbalance between Texas’ energy supply and demand also caused prices to skyrocket from roughly $20 per megawatt hour to $9,000 per megawatt hour in the state’s freewheeling wholesale power market. This is not a surprise.” In California, regulators last week ordered the state’s three major utilities to increase their power supply and potentially make plant improvements to avoid another supply shortage like the one that cropped up in California six months ago and resulted in rolling blackouts affecting about 500,000 people for a few hours at a time. “One big difference is that leadership in California recognizes that climate change is happening, but that doesn’t seem to be the case in Texas,” said Severin Borenstein, a professor of business administration and public policy at UC Berkeley who has been studying power supply issues for more than 20 years.
