Rocky Mountain customers to get one-time
credit from efficiency service over-collection

State regulators have approved a Rocky Mountain Power application to issue a one-time credit
to customers of the eastern Idaho utility due to an over-collection 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 every month. Heavy summer loads during 2012 and 2013 resulted in higher than
forecasted revenues in that account. The Idaho Public Utilities Commission granted the utility’s
request to issue a one-time refund to customers that will be about $8.32 for the average
residential customer. The amount of the credit will vary depending on the amount of energy
use. The credit will be applied against either the February or March bill depending on each
customer’s billing cycle.

The money collected in the rider 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.

The one-time credit will not impact Rocky Mountain’s future expenditures in efficiency
programs. Rocky Mountain anticipates that efficiency expenses will be remain constant this
year with a forecasted increase in 2015.

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 is surpassing its goals for energy efficiency. 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, 2013, the company had achieved 11.47 million kWhs of savings, already
surpassing 2012 totals.
