Wisconsin Public Service: FAQ
- How many power plants does Wisconsin Public Service operate?
- EIA-860M lists 25 operating plants against “Wisconsin Public Service Corp” for 2026-07, totalling 3 GW of nameplate capacity in 3 states.
- Is Wisconsin Public Service the owner of these plants?
- EIA-860M names one reporting entity per generator. That entity operates the plant on the survey; ownership can sit with a parent, a partnership or a tax-equity structure that the form does not record.
- Why are affiliates listed separately?
- Because EIA files them separately. Rolling subsidiaries into a parent would need an ownership map EIA-860M does not publish, so this page does not invent one.
