Rocky Mountain Power agrees to trim hike from 14.7% to 10.2%

An increase to the monthly cost of electricity for 144,000 Wyoming customers is before a regulatory panel with the power to decide whether to approve, and potentially modify, a settlement agreement with Rocky Mountain Power. The proposal reduces the requested increase to continuing electric rates from $123.5 million — as originally proposed in August — to $85.5 million, resulting in an overall 10.2% increase.
