Rate review information
Since 2011, we have kept retail electric base rates flat and managed customer costs through credits, efficiencies and customized solutions. In April 2017, we requested an increase in electric base rates to support investments in our communities.
Wisconsin
Rate review information
For the first time since 2010, we’ve adjusted our electric and natural gas prices (base rates) in Wisconsin for residential customers.
Why? Because we’re focused on a long-term strategy to achieve a cleaner, more efficient power mix. That requires an investment in our generation fleet. At the same time, we’re managing costs and keeping stable rates for customers.
