Electricity costs: A new way they'll surge in a warming world

[font size=3]ANN ARBOR—Climate change is likely to increase U.S. electricity costs over the next century by billions of dollars more than economists previously forecast, according to a new study involving a University of Michigan researcher.
The study shows how higher temperatures will raise not just the average annual electricity demand, but more importantly, the peak demand. And to avoid brownouts and absorb these surges, utilities will need to spend between $70 billion and $180 billion in grid upgrades—power plants and futuristic energy storage systems for which ratepayers would ultimately foot the bill.
"If you look at your own bill across the year, you'll probably see that your usage is highest in the summer, when you're running the air conditioning," said Catherine Hausman, assistant professor at U-M's Gerald R. Ford School of Public Policy.
"Climate change researchers know that when we look out over the next 100 years, things will get warmer and, on a per-person basis, use of air conditioning will rise. The question we asked was 'On the hottest day of the year, when people are maxing out on that, can the grid handle it?' We build the grid for the hottest hour of the year."
