Relating to: calculation of fuel costs for an electric public utility’s fuel cost plan.

SB 733 amends Wisconsin statute to change how electric utilities calculate fuel costs in their approved fuel cost plans. It requires utilities to account for both fuel purchase costs and revenue from selling electricity generation capacity that meets Midcontinent Independent System Operator (MISO) requirements. This applies specifically to fuel cost under-collections or over-collections outside the utility’s allowed annual margin. The bill creates a new definition for "Midcontinent independent system operation" and ties fuel cost calculations directly to MISO standards.
