The commission or the board shall review, in conjunction with each proceeding of the electrical utility held for the purpose of considering changes in electrical rates or charges, the decommissioning costs estimate for the electrical utility in order to ensure that the estimate takes account of the changes in the technology and regulation of decommissioning, the operating experience of each nuclear facility, and the changes in the general economy. The review shall specifically include all cost estimates, the basis for the cost estimates, and all assumptions about the remaining useful life of the nuclear facilities.
