U.S. state grid operators are warning that power generation capacity is struggling to keep up with demand in some areas of the country, a gap that could lead to rolling blackouts during peak periods this year.
A grid operator in California said that the company's current generation capacity could not meet demand this summer, especially when extreme heat, wildfires or delays in bringing new power sources online exacerbate the constraints, Wall Street Journal reported.
The operator said late last month that power shortages could force it to take emergency measures to meet summer demand for electricity.
Parts of Texas have already been affected by the outage. The local power grid has warned of a tight power supply, and the current hot weather sweeping Texas is expected to continue into next week.
The risk of electricity shortages is rising throughout the U.S. as traditional power plants are being retired more quickly than they can be replaced by renewable energy and battery storage. Power grids are feeling the strain as the U.S. makes a historic transition from conventional power plants fueled by coal and natural gas to cleaner forms of energy such as wind and solar power, and aging nuclear plants are slated for retirement in many parts of the country.
"We're all trying to find ways to utilize as much of our renewable resources as possible…and at the same time make sure that we have enough dispatchable generation to manage reliability," said Brad Jones, interim chief executive officer of the Electric Reliability Council of Texas, which operates the state's power grid.
