Wisconsin report examines data center growth, electricity demand and taxpayer costs
A Wisconsin Policy Forum report examines the financial, energy-grid and tax implications of data center development in Wisconsin. It says projects in Mount Pleasant, Port Washington and Beaver Dam are advancing, while other proposals have faced opposition or been canceled, raising questions about electricity costs, tax increment financing and local government safeguards.
A Wisconsin Policy Forum report says Wisconsin has fewer and smaller data centers than states such as Virginia and Ohio, but three hyperscale facilities are being built or operating in Mount Pleasant, Port Washington and Beaver Dam. The report also reviewed proposed projects in Janesville and DeForest that were later canceled. Opposition has led some communities to reject projects or adopt broad moratoriums.
The report identifies electricity demand as a central challenge, with state projections showing peak demand could rise by more than 5 gigawatts from 2024 to 2030. It also examines the potential effects of tax increment financing, infrastructure spending and state sales-tax exemptions, warning that existing taxpayers could initially bear some costs even when agreements include fiscal protections. A Marquette University Law School poll cited in the report found most Wisconsin voters believe large data centers cost more than they benefit communities.
