Michigan’s second largest electric utility says it won’t need to add an extra charge to customer bills to comply with the state’s new, more aggressive targets for accelerating reliance on renewable energy.

Consumers Energy, in a Nov. 15 regulatory filing, estimated new requirements that will compel the utility to source more than half its power from renewable sources like wind and solar power will actually mean $304 million in savings by 2045, compared to a baseline alternative that assumes power is sourced instead from modern natural gas plants burning fossil fuels.
