The PCA has two main components:a balancing account for IDNO
power costs incurred the previous year and a forecast of what
energy will cost in the coming year.
• The balancing account aligns last year's anticipated costs � #
with costs actually incurred during the prior April through 1221 W. Idaho St.
March period. Boise,ID 83702
• The forecast reflects Idaho Power's anticipated fuel costs,
purchased power costs,and customer benefits from sales of
surplus energy for the coming April through March.
The increase in this year's PCA is largely driven by higher
expected power costs for the coming year.This power cost
increase is attributed to lower forecasted hydropower, partially
offset by lower forecasted market energy prices.
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.
