Rocky Mountain seeks to refund customers
for over-collection in rider account

Rocky Mountain Power wants to credit its eastern Idaho customers to reduce the over-
collection of funds in an account that pays for energy efficiency programs.

Customers pay a “Customer Efficiency Services” charge of 2.1 percent of their total billed
amount. The money collected in that account can go only toward funding cost-effective
programs that increase energy efficiency. If the account collects significantly more than the
company anticipated, it must either reduce the rider or refund customers. The rider has
already been reduced from a high of 4.72 percent in 2010 to 2.1 percent today.

Rocky Mountain Power is asking the Idaho Public Utilities Commission to grant its request to
issue a one-time refund to customers that would be about $8.32 for the average residential
customer. The amount of the refund varies depending on the amount of energy use. The credit
would be applied against either the February or March bill depending on each customer’s
billing cycle.

The programs funded by the rider are designed to delay or eliminate the need for the utility to
build new generation. All of the programs funded by the Customer Efficiency Services rider
must pass cost-effectiveness tests that show customers would be paying more for electricity if
the programs were not in place.

Rocky Mountain Power claims that it is surpassing its goals for energy efficiency even with the
reduced amounts in the account. In 2012, the goal was to reach 8.5 million kilowatt-hours of
savings and the company attained 10.54 million kWhs. As of September 30 of this year, the
company has achieved 11.47 million kWhs of savings, already surpassing 2012 totals. The goal
for this year is 14.38 million kWhs.
