Conservation cost recovery adjustment.

(1) Utilities must file with the commission for recovery of all expected conservation cost changes and amortization of deferred balances. A utility must include its conservation cost recovery procedures in its tariff.
(2) A utility must make a conservation cost recovery filing no later than June 1st of each year, with a requested effective date at least sixty days after the filing. If the utility believes that a filing is unnecessary, then it must file a request for exception and supporting documents no later than May 1st of each year demonstrating why a rate change is not necessary.
(3) A utility may not accrue interest or incur carrying charges on deferred conservation cost balances. Utilities must base conservation recovery rates on forward-looking budgeted conservation program costs for the future year with revisions to recover only actual program costs of the prior year. Utilities must also include the effects of variations in actual sales on the recovery of conservation costs in the prior year.
