US power grid regulator NERC is warning of rolling electricity blackouts in parts of the US as extreme temperatures and drought stress the power grid.
- The NERC’s 2022 Summer Reliability Assessment indicated that large swaths of the country are at elevated risk, with the Upper Midwest and Central South at high risk.
- The most severely affected areas will be in the Upper Midwest and in the Central South along the Mississippi River. The latter is a result of damage to a section of a transmission line that has yet to be fixed which carries power to parts of Arkansas, Louisiana, and Mississippi. However, restoration work is expected to be completed at the end of June 2022.
- A cascade of problems like a combination of power plants going off line, low wind and extreme peak demand could force grid operators to impose rolling blackouts.
