What it would mean nearby

We Energies is asking the commission for a 9.3% residential increase (We Energies general electric and gas rate case for 2027 and 2028 (docket 5-UR-112)). On a $160 monthly bill that is about $13 to $17 a month. 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. Transmission upgrades like this are typically billed to every electric customer in the state through transmission charges, not just to the data center that made the new line necessary, which is why the cost allocation question matters for ordinary bills even outside the four counties involved.
