The Minnesota Public Utilities Commission has adopted a schedule of environmental costs for electric utilities evaluating and selecting resource options in all commission proceedings including resource-plan and certificate-of-need cases.
In each such case the utilities will be required to provide three cost analyses for each generation-option provided: one using the values at the low end of the range (see table), one using values at the high end of the range, and one reflecting "direct costs only" (i.e., using zero environmental externalities values).
