The PCA has two main components:a balancing account
for power costs incurred the previous year and an estimate
of what energy will cost in the coming year.The balancing

costs actually incurred the previous April through March. 1221 W. Idaho St.
The estimate reflects Idaho Power's anticipated fuel costs, Boise,ID :
purchased power costs,and customer benefits from sales of
surplus energy for the coming April through March.
The decrease in this year's PCA is largely attributed to the
completed recovery of 2023 deferred power costs,which was
ordered by the IPUC to be recovered over two years.Another
contributing factor was increased sales of renewable energy
credits,which helps to offset power costs for customers.
Neither Idaho Power nor its shareholders receive any financial
return from the PCA—money collected is used to recover
costs or credit benefits associated with annual fluctuations in
power costs.
