The state’s largest utility says it will need energy storage to help it manage a surge of intermittent resources. ComEd sees a significant role for energy storage on Illinois’ electric grid as the state works toward realizing its ambitious renewable goals. “I think you will see that evolution a little bit slower, but it is going to be absolutely a necessary component of the future,” ComEd CEO Joe Dominguez said at a recent City Club of Chicago event. The utility won’t be the only one with a role to play. As they seek to demonstrate the value of storage, state regulators will consider incentives, and developers will have to continue to make it more affordable and efficient.
Energy storage has clear benefits, but its impact on greenhouse gas emissions isn’t fully clear.
Green Mountain Power is expanding solar-plus-storage pilot programs and finding success in the systems’ ability to reduce peak demand.
The rural electric cooperatives are testing how the storage technology can help customers and their systems.
Consumers Energy plans to combine solar and storage in a 4-square-block project in Jackson, Michigan.
