Oracle plans to use electricity from Wisconsin’s only operating nuclear plant to help power Project Lighthouse, a data center campus under development in Port Washington with OpenAI. We Energies announced an agreement Oct. 2 that would allow Oracle to subscribe to between 10% and 20% of the electricity generated by the Point Beach Nuclear Plant in Manitowoc County. The agreement must be approved by the Wisconsin Public Service Commission. We Energies spokesperson Brendan Conway said approval could reduce fuel costs for the utility’s other customers by roughly $300 million over five years. Point Beach, which is about 60 years old, is Wisconsin’s largest electricity generator. Its power is more expensive than other options, and We Energies spends about twice as much on fuel as Wisconsin Public Service, a related utility. Nuclear fuel costs account for much of that difference, according to the reported figures. We Energies sold Point Beach to energy company NextEra Energy in 2007 but continued buying most of its output. Its current purchase agreement runs through 2033. The utility recently agreed to keep buying about 86% of the plant’s electricity for an additional 20 years. The Oracle agreement comes as demand from large data centers raises questions about how new electricity needs will affect utility costs and energy sources. On Oct. 2, We Energies also asked the state commission to approve a new natural gas power plant at the Fox Energy Center in Outagamie County. The proposed facility would more than double the site’s electricity output.
