We Energies general electric and gas rate case for 2027 and 2028
We Energies, WI
As filed, a typical residential bill would rise about 13 dollars a month in 2027 and 8 to 9 dollars more in 2028, but how much of that is really tied to data centers versus other grid needs is one of the contested questions in the case.

Alliant Energy individual electric service contract for Meta's Beaver Dam data center
Alliant Energy Wisconsin, WI
Meta says the contract means other Alliant customers will not pay for the energy used by its Beaver Dam data center, though consumer advocates say the secrecy around the deal makes that hard for the public to independently verify.

This tariff does not change home electric rates by itself, but it is meant to make large new data centers pay the full cost of the power plants and lines built to serve them instead of spreading those costs across everyone's bill.
