New data center rate structure risks Wisconsinites picking up the bill for Big Tech
MILWAUKEE, Wis. – The Wisconsin Public Service Commission (PSC) is considering a new rate structure on data centers that favors profits and protections for Big Tech companies and We Energies, putting Wisconsinites at risk to subsidize the infrastructure costs needed for these billion-dollar companies to run their data centers. We Energies is preparing to now spend $19.3 billion on electric generation over the next five years, an increase of nearly $10 billion since the 2024-2028 five-year plan, largely driven by data center proposals from Microsoft, Oracle, Vantage, and OpenAI
In response, Cassie Steiner, Senior Campaign Coordinator, released the following statement:
“As data center proposals continue to surge across the state, Wisconsin regulators must enforce common-sense, protective measures that will ensure Big Tech will be responsible for paying for their massive data centers, not Wisconsinites. It’s no secret that Big Tech and monopoly utility companies like We Energies are using the AI boom to exploit Wisconsin's resources and squeeze communities for profit. We’re asking for fair, pragmatic implementations that won’t force Wisconsinites to pick up the bill for greedy tech companies. Big Tech must pay its own way, be transparent and accessible in all of its reporting and planning, and be required to use clean energy in order to protect customers from fuel fluctuations.”
Sierra Club’s testimony highlighted the potential impacts on ratepayers and concluded:
- A new report by Energy Futures Group found that the demand for gas from these data centers, if they aren’t required to use clean energy, would increase energy costs for all ratepayers. To prevent this, data centers should be required to use clean energy to protect customers from fuel fluctuations. Key findings of the report include:
- Serving large data center loads with gas exposes the whole system — and therefore all ratepayers — to volatile natural gas prices, not just the data centers that will drive the build-out of gas.
- When modeled across low, base, and high gas price scenarios, a portfolio dominated by new gas units has significantly higher operational costs than portfolios that rely more on renewables and storage — with cost gaps ranging from $136M–$559M depending on scenario.
- Adding more renewables and storage reduces exposure to fuel price risk, and even when assuming no federal renewable tax credits, these portfolios still had lower total system costs once fuel risk was accounted for.
- The report concludes that large-load customers (e.g., data centers) can shift financial risk (especially for fuel cost) onto other customers, including households and small businesses.
- To protect ratepayers from subsidizing costs, data centers must pay for 100% of the new energy demand, including the costs of new infrastructure, such as new gas and renewable projects and new transmission lines. The current proposal does not adequately protect We Energies’ customers.
- The current proposal does not ensure that all data centers are required to be part of the current tariff structure. In order to protect ratepayers from stranded asset costs and paying for prospecting on Big Tech’s part, the tariff and associated rate schedule must be mandatory for every data center owner and operator, and they need to be locked in for the life of the infrastructure that is created to support their data center. Otherwise customers are footing the bill.
