According to CNET, according to a [report] from North American power reliability Corporation (NERC) on Wednesday( https://www.nerc.com/news/Headlines%20DL/May%2018%202022%20SRA%20Announcement.pdf ) , people in Michigan, Texas and California are at risk of blackouts throughout the summer** The company said that the Midwest of the United States is at "high risk", while the rest of the United States is at "high risk" of energy emergencies.
NERC said above average seasonal temperatures and drought conditions were the culprits. The drought will affect how much energy hydro generators can produce and the output of thermal generators that need water to maintain cooling.
Drought has been a problem in the western and southwestern United States since early 2021. Satellite images of Lake Powell in Arizona show that the water level there is falling.
"However, persistent and extreme droughts and their associated weather patterns are unusual and tend to put additional pressure on power supply and demand," said Mark Olson, NERC's reliability assessment manager
NERC's report also found that supply chain problems, active late summer wildfire season and continuous network security threats are all factors that may affect the reliability of power grid in summer.
