Section PSC 116.06 - Deferred account balance calculation
Current through August 26, 2024
(1) A deferred account balance debit shall be calculated using the following formula:
If AAFC is [GREATER THAN EQUAL TO] (AAFCF x (1+FCT))
Then DABD = WJR x [AAFC - (AAFCF x (1 + FCT))]
Where DABD = Deferred account balance debit.
WJR = Wisconsin jurisdictional share of the annual native system requirement.
AAFC = Average annual fuel cost.
AAFCF = Forecast of the average annual fuel cost in the approved fuel cost plan.
FCT = Fuel cost tolerance.
(2) A deferred account balance credit shall be calculated using the following formula:
If AAFC is < (AAFCF x (1-FCT))
Then DABC = WJR x [(AAFCF x (1 - FCT)) - AAFC]
Where DABC = Deferred account balance credit.
WJR = Wisconsin jurisdictional share of the annual native system requirement.
AAFC = Average annual fuel cost.
AAFCF = Forecast of the average annual fuel cost in the approved fuel cost plan.
FCT = Fuel cost tolerance.
(3) A utility's fuel cost tolerance shall be set at plus or minus two percent, unless the commission sets a different percentage when approving a fuel cost plan under s. PSC 116.03(3).
