9 February 2010 - Consumers Energy was ordered to refund $86 million to its customers by the Michigan Public Service Commission for what regulators said was a failure on the part of the utility to use money designated for the decommissioning of the Big Rock Point nuclear power plant for its intended purpose. The Commission said that Consumers Energy instead used money for "general purposes."
Michigan regulators have given Consumers Energy 30 days to devise a plan to credit 1.8 million customers based on power usage. The refund must be completed within 18 months.
The utility said it did manage the decomissioning properly.
Big Rock Point was the longest running and oldest operating nuclear plant in the US at the time of its decommissioning, having operated for 35 years. It was Michigan's first nuclear power plant. Generating capacity of the plant was 67 MW.
