Generation Cost Savings are calculated as the difference in net present value (NPV) of the cost of generation (both capital costs and operational generation costs) across the period of 2025-2054 between the BAU scenario and clean repowering scenario for each load-serving entity (LSE).
Utilization Rate is essentially the capacity factor of a point of interconnection. It is calculated as the total deliverable annual generation of all the resources that share the incumbent generator's point of interconnection divided by the maximum deliverable generation possible in that year (the capacity of the incumbent generator multiplied by the number of hours in the period.).
