The Claims Administrator shall calculate the allowable amount of the covered costs claimed in the Certification of Covered Costs as follows:

Costs covered through Program Account. The principal or interest on any debt obligation financing the advanced nuclear facility for the duration of covered delay to the extent the debt obligation was included in the calculation of the loan cost; and

Costs covered by Grant Account. The incremental costs calculated for the duration of the covered delay. In calculating the incremental cost of power, the Claims Administrator shall consider:

Fair Market Price. The fair market price may be determined by the lower of the two options: The actual cost of the short-term supply contract for replacement power, purchased by the sponsor, during the period of delay, or for each day of replacement power by its day-ahead weighted average index price in $/MWh at the hub geographically nearest to the advanced nuclear facility as posted on the previous day by the Intercontinental Exchange (ICE) or an alternate electronic marketplace deemed reliable by the Department. The daily MWh assumed to be covered is no more than its nameplate capacity multiplied by 24 hours; multiplied by the capacity-weighted U.S. average capacity factor in the previous calendar year, including in the calculation any and all commercial nuclear power units that operated in the United States for any part of the previous calendar year; and multiplied by the average of the ratios of the net generation to the grid for calculating payments to the Nuclear Waste Fund to the nameplate capacity for each nuclear unit included. In addition, the Claims Administrator may consider “fair market price” from other published indices or prices at regional trading hubs and bilateral contracts for similar delivered firm power products and the costs incurred, including acquisition costs, to move the power to the contract-specified point of delivery, as well as the provisions of the covered contract regarding replacement power costs for delivery default; and

Contractual price of power. The contractual price of power shall be determined as the daily weighted average price in equivalent $/MWh under a contractual supply agreement(s) for delivery of firm power that the sponsor entered into prior to any covered event. The daily MWh assumed to be covered is no more than the advanced nuclear facility's nameplate capacity multiplied by 24 hours; multiplied by the capacity-weighted U.S. average capacity factor in the previous calendar year, including in the calculation any and all commercial nuclear power units that operated in the United States for any part of the previous calendar year; and multiplied by the average of the ratios of the net generation to the grid for calculating payments to the Nuclear Waste Fund to the nameplate capacity for each nuclear unit included.
