Citizen Activism
In January 2010, Montana-Dakota Utilities proposed a 25% overall rate hike due to the utility's investment in the plant, Wygen Unit 3, after an initial request of 30%. Citizens, particularly the Powder River Basin Resource Council, opposed the hike, as seen in this video.[4]
In March 2010, MDU announced it had reached a settlement for an increase of 16 percent. The Wyoming Public Service Commission has until June 14 to rule on the settlement. In the price settlement, the parties agreed to stipulations including a lower return on equity of 10.9 percent, special provisions for irrigation customers, and a phased-in increase over three years "to mitigate the rate shock effect on customers," according to the agreement.[4]
Black Hills Power has requested an 11.5 percent return on equity.[4]
