Senate Bill 780 establishes a percentage of income payment program for electricity and gas services, aimed at assisting severely energy burdened and energy burdened households in Wisconsin. The bill mandates that the Public Service Commission (PSC) ensure that the monthly utility costs for these households do not exceed 2% of their annual income divided by 12. It defines a severely energy burdened household as one where monthly utility bills equal 4% or more of their annual income, or where there is no income at all. The PSC is tasked with automatically enrolling eligible households in the program, conducting outreach to communities with high proportions of such households, and providing financial assistance as needed. Additionally, the bill prohibits disconnections of utility services for households with incomes below 300% of the federal poverty guidelines and requires utilities to report disconnections annually.

The bill also creates an energy burden relief fund, which will be funded by gross revenues from public utilities, and outlines the PSC's authority to set rates and provide financial assistance based on household income. It includes provisions for the PSC to submit annual reports to the governor and legislature regarding the program's administration, participation, and any barriers faced by customers. The bill renumbers existing statutes and introduces new sections to facilitate the implementation of the program, ensuring that the financial obligations for electricity and gas services are manageable for low-income households.
