(1) A utility electing to participate in the incentive program must notify the energy program of such election in writing.

(2) The utility may terminate its voluntary participation in the incentive program by providing notice in writing to the energy program to cease issuing new certifications for renewable energy systems that would be served by that utility.

(3) Such notice of termination of participation is effective after fifteen days, at which point the energy program may not accept new applications for certification of renewable energy systems that would be served by that utility.

(4) Upon receiving a utility's notice of termination of participation in the incentive program, the energy program must report on its web site that customers of that utility are no longer eligible to receive new certifications under the incentive program.

(5) A utility's termination of participation does not affect the utility's obligation to continue to make annual incentive payments for electricity generated by systems that were certified prior to the effective date of the notice. The energy program must continue to process and issue certifications for renewable energy systems that were received by the energy program before the effective date of the notice of termination.

(6) A utility that has terminated participation in the program may resume participation upon filing notice with the energy program.
