Section 116.06. Deferred account balance calculation.

 

(1)  A deferred account balance debit shall be calculated using the following formula:

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) .
