Rocky Mountain Power rate filing reflects low-cost,clean energy transformation
BOISE (May 27,2021)-Rocky Mountain Power filed a request today with the Idaho Public Utilities
Commission to implement its long-term plan to modernize how the company produces,transports,and
delivers electricity to power Idaho's future.
After eight years of significant improvements to Rocky Mountain Power's energy backbone serving
customers in Idaho without raising rates,this proposal aligns rates with the actual cost of providing
service to customers and allows Idaho to continue to have some of the most affordable,reliable and
increasingly renewable power in the country.The request includes the following projects:
Rocky Mountain Power's Energy Vision 2020 renewable energy and transmission initiatives,
other wind repowering projects,installation of clean air improvements on certain generating
units,and continued investment in the transmission system.
Significant capital investment has been made to rebuild the Rigby to Rexburgtransmission line
to improve reliabilityfor customers in the southeastern Idaho region.This work is part of a
larger project to increasethe capacity of the Goshen substation.Once completed,the project
will improve system reliabilityand provide for increasedcustomer needs.
The last increase to Rocky Mountain Power's base rates was in 2014.During the past decade,the
company continued to prepare for the future with important renewable energy and electric grid
upgradesthat nearly doubles the amount of renewable energy capacity availableto serve customers.
With no fuel costs,these renewable energy projects are expected to save customers several hundred
million dollars over the lives of these assets.During 2014 to 2018,and again in 2020,declining costs of
fuel and wholesale power resulted in modest reductions to Idaho customer bills in each of those years.
Beginning in 2022,the proposed new rates would result in an increase of $19.0 million or 7.0 percent for
customers overall.On average,residential customers would see an increaseof about $10.32 per month.
"Rocky Mountain Power is proud to serve our customers with affordable,safe,reliable and increasingly
clean electricity,"said Gary Hoogeveen,president,and CEO of Rocky Mountain Power."Rocky Mountain
Power has the lowest averageelectricity price of any large electrical utility in the Intermountain West
with prices that are about 25 percent lower than the national average."
In pre-filed testimony supporting the company's request,Hoogeveen noted that the company's strict
cost-control measures have been accomplishedwhile also improving reliabilityto the 85,600 customers
the company serves in Idaho.
What's next?
The Idaho commission will examine Rocky Mountain Power's requests and will determine whether the
request should be accepted as filed,modified,or rejected.The rate change ordered by the commission
would take effect on Jan.1,2022.The commission has the authorityto set final rates that may be lower
than the company's request,depending on the outcome of its examination.Rocky Mountain Power's
initial request proposesthe following changes by rate schedule:
Proposed Price Change-Effective Jan.1,2022
