Senate Bill 733 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 associated with fuel and energy transactions but also the costs of purchasing and the revenue earned 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 fuel cost calculations, ensuring that utilities can account for all relevant financial factors.

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 recovery or refunds. This legislative change is intended to enhance the regulatory framework governing fuel cost plans and improve the financial stability of electric public utilities in Wisconsin.
