Consumers Energy, the largest utility in the US state of Michigan, filed an integrated resource plan (IRP) with regulators that calls for a dramatic renewables expansion and the elimination of coal over the next two decades, with wind to benefit in the near term but solar to dominate after the early 2020s.

The IRP, filed at the end of last week with the Michigan Public Service Commission, envisages Consumers eliminating coal altogether by 2040, while its share of renewables rises from 11% today to 43%.
