Policy Update, 1 October 2026

The 2023 equipment sales tax exemption remains in place, while draft legislation for a statewide moratorium is circulating. In Milwaukee, a proposed one-year data centre moratorium passed the Plan Commission on 28 September 2026, with a committee vote set for 6 October and a Common Council vote on 13 October. At the federal level, FERC issued show-cause orders on large-load interconnection to all six RTOs and ISOs on 18 June 2026, and PJM filed a framework on 13 August 2026 under which new loads of 50 MW or more that do not bring their own capacity face curtailment ahead of other demand response from 1 June 2027.

Figures compiled from the Edison Electric Institute's "Large Load Projects and Tariffs" (September 2026) member-company summary and public regulatory filings. Confirm current tariff terms directly with We Energies / Xcel Energy / Madison Gas and Electric / Wisconsin Power and Light and the relevant state public utility commission before relying on any figure for a capital decision.

Weighing Wisconsin against another state or a Canadian province with a different rate and interconnection picture entirely? Run both sides of the comparison through our licensed AI data center cost configurator — it applies each jurisdiction's actual power rate, tax treatment and large-load tariff rules to the same seven build configurations.

We Energies’ Very Large Customer and Bespoke Resources tariffs are built for exactly this kind of load; our crypto data center in BC shows what the same siting questions look like under a hydro-based utility.

Frequently Asked Questions

What is We Energies' Very Large Customer (VLC) and Bespoke Resources Tariffs?

100 MW or greater (Xcel); a dedicated Very Large Customer class (We Energies, Madison Gas and Electric) depends on the utility: We Energies has an approved Very Large Customer (VLC) Tariff and Bespoke Resources Tariff, Madison Gas and Electric has proposed the same pairing, Xcel Energy has proposed a Very Large General Time of Day Service tariff for 100 MW-plus loads, and Wisconsin Power and Light has proposed Schedule Cp-3, a Large Load Power Service Tariff with its own Electric Service Agreement and Customer Reimbursement Agreement.

Why did We Energies / Xcel Energy / Madison Gas and Electric / Wisconsin Power and Light introduce this large-load structure?

To ensure the cost of new generation, transmission and distribution infrastructure built to serve very large customers, chiefly hyperscale data centers, is paid for by those customers rather than spread across the general rate base of residential and small commercial ratepayers.

What large data center projects are already active in Wisconsin?

We Energies (WEC Energy Group) is serving a $15 billion, 1,300 MW OpenAI/Oracle/Vantage 'Stargate' campus in Port Washington and a $20 billion, up to 2,600 MW Microsoft investment in Mount Pleasant — among the largest single-state commitments on this list.

Does this tariff replace Wisconsin's standard commercial and industrial rates?

No. We Energies' Very Large Customer (VLC) and Bespoke Resources Tariffs sits above We Energies / Xcel Energy / Madison Gas and Electric / Wisconsin Power and Light's standard commercial and industrial rate schedules and applies specifically to customers that meet or exceed the large-load threshold described above. Smaller commercial and industrial loads continue to be billed under existing rate schedules.

How can I model a Wisconsin data center build against this tariff and other states?

The SCR AI Build Configurator applies Wisconsin's power cost, tax treatment and large-load tariff rules alongside all other US states and Canadian provinces, so a Wisconsin scenario can be compared line-by-line against any alternative site.
