For more than a century, Rocky Mountain Power has provided safe, reliable and competitively-priced electric service, and we appreciate the opportunity to serve you, our Wyoming customers. While price increases are necessary at times to support the costs of maintaining the quality of service our customers deserve and expect and to comply with state and federal requirements, we are committed to controlling expenses and helping customers save money by using electricity efficiently. Working together, electricity in Wyoming can remain a good value now and into the future.


Annual cost adjustments proposed for 2014

Rocky Mountain Power is required to adjust its Wyoming prices each year, either up or down, to match customer prices with certain actual expenses and revenues that can fluctuate significantly. These annual adjustments must be approved by the Wyoming Public Service Commission before they can take effect.

The company has requested 2014 price changes through its Energy Cost Adjustment Mechanism (ECAM) and REC and SO2 Revenue Adjustment Mechanism (RRA), which if approved by the Wyoming Public Service Commission would result in an overall average increase of approximately 3 percent, to occur on May 15. A residential customer with average electricity use of 780 kilowatt-hours per month would see a monthly increase of about $1.77.

The ECAM and RRA processes address separate costs from those included in the company’s pending general price increase request, which if approved would take effect in January 2015.

Through the ECAM, expenses such as fuel for power plants, purchased power and the cost to deliver electricity on transmission lines owned by others, as well as revenue from market energy sales to other providers, are examined to more closely match actual costs with the prices customers pay for electricity. Wyoming customers only pay for their portion of these energy costs.

Through the RRA, forecast revenues for market sales of renewable energy credits and sulfur dioxide emission allowances are examined and compared to actual revenues, and prices are adjusted accordingly.

For several years, Wyoming customers have received significant benefit from the company’s sale of RECs and SO2 emission allowances because 100 percent of the revenues are passed on to customers. However, the amount of that credit has been drastically reduced over the past two years, largely due to changes in California law that have greatly diminished the market for sales of REC and SO2 emission allowances by out-of-state providers.

Rocky Mountain Power continues to do everything possible to control costs and ensure that any expenses provide clear value for our customers.
