Assembly Bill 751 proposes amendments to the calculation of fuel costs for electric public utilities in Wisconsin. The bill requires that when a public utility files a fuel cost plan with the Public Service Commission (PSC), the calculation of fuel costs must include not only the net costs and credits from fuel and energy transactions but also the costs associated with purchasing and the revenue from selling electricity generation capacity that meets the standards set by the Midcontinent Independent System Operator (MISO). This change aims to provide a more comprehensive approach to determining fuel costs in the utility's rate recovery process.

Additionally, the bill creates a new definition for "Midcontinent independent system operation" and amends existing language regarding the deferral of under-collection or over-collection of fuel costs. Specifically, it clarifies that the PSC must defer any discrepancies in fuel costs that fall outside the utility's established symmetrical fuel cost annual tolerance for future rate adjustments. This legislative change is intended to enhance the accuracy and fairness of fuel cost calculations, ultimately benefiting both utilities and consumers.
