Chapter PSC 111

PSC 111.25(1) (1) Definition. In this section, “electric power supply” means aggregate generating capacity plus capacity additions, capacity upgrades or improvements at existing units, and capacity purchases without reserves as defined in s. PSC 111.23 (1) (a), less unit retirements, capacity downgrades at existing units, and capacity sales without reserves as defined in s. PSC 111.23 (1) (b).

PSC 111.25(2) (2) Data submission. Each electricity provider, except operators of wholesale merchant plants, shall calculate electric power supply for the 7-year period encompassing the SEA and submit the results to the commission. Any part of a capacity purchase without reserves, as defined in s. PSC 111.23 (1) (a), that is intended to compensate for transmission losses associated with delivery of that purchase, shall be excluded from the calculation of electricity power supply. All miscellaneous supply factors that decrease supply resources shall be deducted from electric power supply. All miscellaneous supply factors that increase supply resources shall be added to electric power supply.
