National forecasters are predicting another hotter-than-normal summer. That could mean more of the rolling blackouts likes those San Antonio experienced in 2011.
Climatologists predict temperatures will be above normal this year and the power grid may not be able to keep up. The North American Electric Reliability Corporation projects the Texas grid will have the lowest percentage of power reserves this summer of any region in the country.
The problem is rapidly-growing demand combined with a lack of new power plants being built.
