For decades, managers of electric grids feared that surging energy demand on hot summer days would force blackouts.
Largely because of growing demand from homes and businesses, and supply constraints due to aging utility equipment, many grids are under greater strain in winter.
Just 10 years ago, winter electricity use ran about 11 percent less than in summer, according to the group.
And by 2050, winter demand could surpass electricity use in the summer.
“We’re seeing both summer and winter peaks growing, but we’re seeing winter peaks growing faster,” said Jim Robb, chief executive of the reliability corporation.
