CHEYENNE, Wyo. (AP) - The Wyoming Public Service Commission has approved rate hikes for two utilities with customers in the state. The commission on Friday approved Rocky Mountain Power's proposal to increase overall rates by 5.1 percent in July and 1.9 percent in February to generate another $35.5 million per year.
The approval also covers the utility's plan to decrease rates by an overall average of 3.8 percent this year as part of a power cost adjustment. Rocky Mountain Power serves more than 134,600 customers in Wyoming. Earlier this week, the commission approved a proposal by Black Hills Power to raise rates 32 percent for its Wyoming customers. Black Hills serves about 2,700 customers in northeastern Wyoming.
