Midwest Energy News

The amount of solar power on the Midwest’s electricity grid is minuscule enough that a cloudy day doesn’t cause problems for the system.

As solar makes inroads, though, utilities may eventually need new tools to make sure they can continue providing cheap, steady power when the sun goes behind a cloud.

Several efforts are currently underway to provide the industry with better sunlight forecasts, much like what grid operators currently use for wind power. Earlier this month the U.S. Department of Energy announced $8 million in funding for two projects to improve solar forecasting.
