Rate Recommendations by Use Case
Mid-size commercial facility
A 200,000 therm/year facility on firm sales pays the Fg-4 $0.1960/therm distribution plus Base Gas and PGA. Compare against Tf-4 transportation with a marketer.
At this volume the commodity component dominates the bill, so self-supply via transportation often beats bundled sales.
- Pull 12 months of therms from My Account/MyMeter
- Solicit marketer quotes against Base Gas + PGA
- Model the $17/day Tf-4 customer charge into the comparison
Large industrial plant
A 3,000,000 therm/year plant fits Fg-6/Tf-6 (1M-7.99M therms). Firm transportation Tf-6 is $0.0531/therm plus $0.0058/therm/day demand and $117/day customer charge.
High-volume declining-block distribution plus self-supply minimizes delivered cost; interruptible adds savings if the plant can curtail.
- Negotiate marketer gas supply for Tf-6
- Assess curtailment tolerance for Ig-6
- Watch daily balancing/imbalance exposure on transportation
Energy/data team automating bill capture
With no public API or Green Button, automate via EDI 810 (business billing) and use MyMeter/EIS exports for usage; consider Nectar for API-based bill capture (docs.nectarclimate.com).
EDI is the only structured machine-readable feed; everything else is manual export or TPVA-authorized request.
- Stand up a VAN and sign the EDI Trading Partner Agreement
- Schedule MyMeter/EIS exports
- Use Nectar for API-based billing data (docs.nectarclimate.com)

Cost Optimization Strategies
Because distribution charges decline by volume tier and firm transportation removes the utility commodity markup, C&I customers can materially cut delivered cost by right-sizing their rate class and self-supplying gas where volumes justify it.
Move to firm transportation (Tf)
For: C&I with 100,000+ therms/year
At high volume, take firm transportation service and buy gas from an authorized marketer rather than paying the bundled Base Gas + PGA.
Confirm correct rate tier
For: All C&I
We Energies assigns rate class from trailing 12-month usage; verify you are in the lowest-cost Fg/Tf tier for your volume.
Evaluate interruptible (Ig) service
For: Large industrial with curtailment capability
If you have dual-fuel or backup capability, interruptible service offers lower distribution and base-gas rates in exchange for curtailment on one-hour notice.
Manage transportation balancing
For: Transportation (Tf) customers
Transportation customers face daily balancing rules and imbalance penalties; tight nomination management avoids cash-out charges.

Frequently Asked Questions
Does Wisconsin Gas (We Energies) support Green Button or a public API?▾
No. We Energies does not offer Green Button Download/Connect My Data or a public developer API. Structured access is limited to EDI 810/820 for business billing; usage data is exported manually from MyMeter or EIS, or obtained via a TPVA-authorized request.
How can a C&I customer get interval gas data?▾
AMI-metered accounts can view and export 15-minute to annual data in MyMeter. Gas transportation customers get hourly and daily consumption plus weather/degree-day data through the Energy Information System (EIS).
How does a third party (consultant or marketer) access our data?▾
The customer signs a Third-Party Verification Agreement (TPVA) naming the agent and data scope, and mails it to We Energies. The agent then registers with the Business Center; data requests typically take 3-5 business days. Marketers serving transportation customers use the EIS channel.
What are the current 2026 C&I gas rates?▾
Effective January 1, 2026 (PSCW Docket 5-UR-111), firm sales (Fg) ranges from $0.4353/therm distribution at the smallest tier down to about $0.0939/therm at the largest, plus Base Gas $0.5114/therm and a monthly PGA. Firm transportation (Tf) ranges from $0.3628/therm down to $0.0214/therm with no utility commodity charge.
Should we take firm transportation instead of firm sales?▾
Often yes above ~100,000 therms/year. Firm transportation (Tf) lets you buy gas from an authorized marketer and pay only delivery, avoiding the bundled Base Gas + PGA. You take on daily balancing and imbalance-penalty responsibilities, so model both before switching.
