Alliant Energy's Wisconsin utility asked for an electric increase of about 8.3 percent in 2026 and 5.7 percent in 2027, plus a smaller natural gas increase, citing grid investment. The Public Service Commission approved a unanimous settlement, trimming the increase to 5.4 percent in 2026 and 5 percent in 2027 on electric rates, which works out to about 9.57 dollars a month more on a typical residential bill in 2026 and 17.45 dollars a month more in 2027 compared with 2025.
