Alliant Energy's Wisconsin residential electric customers will pay about $10 more per month, on average, for electric service next year under a two-year rate plan approved by the Wisconsin Public Service Commission.

The following year, rates will go up again, adding another $8 per month to the average bill, according to a preliminary analysis by PSC staff.

By 2025, the average residential customer will pay an additional $214 per year for electric service, 16 percent more than this year. Customers' bills for natural gas service will increase about $4 a month in 2024, but will be essentially flat in 2025, according to the PSC analysis.
