There have been warnings about possible rolling blackouts for electricity customers in Illinois this summer. So far that hasn’t been a problem.

Jim Chilsen with the Citizens Utility Board says if MISO, or the multi-state power grid operator in charge of power generation and transmission, would move to approve more than 30 renewable energy projects the grid would be strengthened with 6,000 additional megawatts of electricity.

6,000 megawatts of electricity could power 4.5 million homes.
