Rate Schedules & Tariff Analysis
WPS C&I customers fall into two electric tiers: small energy-only service (under 100 kW or 25,000 kWh/month) with a flat per-kWh energy charge and daily customer charge, and demand-billed general/large power schedules for larger loads where peak demand ($/kW) drives a large share of the bill. Optional time-of-use rates (Cg3-OTOU) can reward off-peak load shifting. Gas customers pay a facility charge plus per-therm distribution plus commodity, with transportation available to large users.

Wisconsin Public Service (WPS) Data Access FAQ
Does WPS offer an API or Green Button for third-party data access?▾
No. WPS does not provide a public developer API, REST/SOAP web services, or Green Button (Download or Connect My Data). It is not listed in the Green Button Alliance directory. The only programmatic pathway is the Energy Information System (EIS) for eligible business customers, which can grant an authorized third party a separate login with written customer consent.
How does a consultant get authorized to receive a customer's WPS usage data?▾
The customer must complete a Third-Party Verification Agreement (and a usage-information release form for detailed data), specifying the authorized party and the data scope, then submit it by mail or to customerservice@wisconsinpublicservice.com. WPS updates records in about 5-10 business days. WPS will not send confidential usage data to a third party without this authorization on file.
What interval granularity can a business customer get?▾
Through MyMeter, electric interval data is available at 15-minute or 30-minute granularity where the advanced meter supports it, otherwise hourly/daily. Eligible gas transportation and interruptible customers can access hourly and daily consumption through the Energy Information System (EIS).
Which electric rate applies to a small business?▾
Small commercial and industrial customers using under 100 kW or 25,000 kWh per month are typically billed energy-only, with a daily customer charge plus a per-kWh energy charge. Larger customers that exceed those thresholds move to demand-billed general/large power schedules. Confirm your exact rate in the WPS Wisconsin electric tariff.
Can a WPS C&I customer shop for a competitive electric supplier?▾
No. Wisconsin does not have retail electric choice, so WPS electric rates are bundled and regulated by the PSCW. For natural gas, however, large customers can take transportation service and buy their own gas commodity through an approved marketer while WPS delivers it.
