We Energies signed a new 20-year agreement to purchase electricity from the Point Beach nuclear plant in Manitowoc County, resolving uncertainty about the relationship between the utility and the state’s largest power plant. 

The agreement, disclosed in a U.S. Securities and Exchange Commission filing, still requires sign-off from Wisconsin’s Public Service Commission.

The roughly 60-year-old facility is Wisconsin’s only active nuclear power plant. We Energies owned the plant until 2007, when it sold Point Beach to a Florida-based utility. It currently purchases most of the plant’s output from independent energy infrastructure giant NextEra Energy.
