The INTENDED consequences of climate policy: 'Electricity shortage warnings grow across U.S.'
From California to Texas to Indiana, electric-grid operators are warning that power-generating capacity
is struggling to keep up with demand, a gap that could lead to
rolling blackouts during heat waves or other peak periods as soon as this year.

California’s grid operator said Friday that it anticipates a shortfall in supplies this summer, especially if extreme heat, wildfires or delays in bringing new power sources online exacerbate the constraints. The Midcontinent Independent System Operator, or MISO, which oversees a large regional grid spanning much of the Midwest, said late last month that capacity shortages may force it to take emergency measures to meet summer demand and flagged the risk of outages. In Texas, where a number of power plants lately went offline for maintenance, the grid operator warned of tight conditions during a heat wave expected to last into the 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.
The challenge is that wind and solar farms—which are among the cheapest forms of power generation—don’t produce electricity at all times and need large batteries to store their output for later use. While a large amount of battery storage is under development, regional grid operators have lately warned that the pace may not be fast enough to offset the closures of traditional power plants that can work around the clock.
