For 100 years, Rocky Mountain Power has provided safe, reliable and competitively-priced electric service, and we appreciate the opportunity to serve you, our Wyoming customers.
For all electricity makes possible in our homes, businesses and communities, it continues to be a very good value. Over the next decade, however, prices will unavoidably increase primarily due to growing electricity use by Wyoming customers, rising fuel costs and increasingly stringent environmental regulations. This is happening in many areas across the nation.
Rocky Mountain Power is committed to remaining a low-cost electricity provider, controlling expenses and helping customers to save money by using electricity efficiently. Working together, electricity in Wyoming can remain a good value now and into the future.
Approved agreement provides greater electricity price certainty
An agreement between Rocky Mountain Power and organizations representing Wyoming electricity consumers has been approved by the Wyoming Public Service Commission. The agreement benefits our Wyoming customers by keeping electricity price changes more predictable and manageable over the next few years. It also addresses our growing costs to provide continued safe and reliable electric service to customers in Wyoming.
As a result of this agreement, prices for Wyoming customers decreased in July 2012 through changes to the company’s annual energy cost adjustment for this year. This price decrease will be followed by moderate general price increases in October 2012 and October 2013. Any subsequent general price increase will not take effect before January 2015. Ongoing annual filings for power costs and other balancing account items will take place on their normal schedules.
For an average residential customer, the net impact of the July and October 2012 price changes in this agreement is an increase of 88 cents per month, followed by an increase of $1.60 per month in October 2013.
Wyoming customers as a whole are using more electricity and the cost to produce it has gone up. The expense of complying with environmental regulations is also a major factor in our recent price increase requests, specifically the cost of adding new air quality controls on our coal-fueled power plants.
We continue to control all of the costs we can control in order to keep electricity a good value for our customers, and our employees are doing more with less. Customers can lessen the impact of price increases and really take charge of their electricity bills by using our proven wattsmart energy efficiency programs. We also have programs to help equalize or extend bill payments. (See Online Resources below.)
Price changes will vary for different types of customers, as indicated in the following chart. Prices will also vary for customers based on how much electricity they use.
