Rate Schedules & Tariff Analysis
PSE C&I electric pricing is a demand ladder (Schedule 24 energy-only under 50 kW, Schedule 25 for 50-350 kW, Schedule 26 over 350 kW) regulated by the WA UTC. Demand charges are seasonal (notably higher Oct-Mar, reflecting winter-peaking load), and a reactive power charge applies to larger loads, so power-factor and peak management drive cost. Primary-voltage service on Schedule 26 earns demand/energy credits but carries a winter demand ratchet. The 2024-25 general rate case (UE-240004/UG-240005) sharply raised demand and basic charges effective Jan 29, 2026. Gas C&I is firm sales (Schedule 31) or self-supplied transportation (Schedule 31T), with annual cost-of-gas adjustments each November.
Puget Sound Energy, Inc. (PSE) Rate Schedule List
| Schedule | Applicability |
|---|---|
| Schedule 26 - Large Demand General Service | Primary large C&I schedule, over 350 kW |
| Schedule 25 - Small Demand General Service | Mid-size C&I, 50-350 kW |
| Schedule 24 - General Service | Small C&I, under 50 kW |
| Schedule 31 / 31T - C&I Gas | Firm commercial/industrial gas sales and transportation |
Puget Sound Energy, Inc. (PSE) Rate Features & TOU Details
- Demand ladder: Sch 24 (<50 kW) -> Sch 25 (50-350 kW) -> Sch 26 (>350 kW)

- Reactive power (kVArh) charge on loads at or above 100 kW
- Schedule 26 primary-voltage credits plus an Apr-Nov demand ratchet (60% of prior winter peak)
- Large Jan 29, 2026 increases from the 2024-25 general rate case (~12% net electric)
- Gas Schedule 31 firm sales vs 31T self-supply transportation; annual Nov cost-of-gas reset
- Numerous riders: power cost adjustment (Sch 95), decoupling (Sch 142), clean energy, GHG cap-and-invest (Sch 111)

Puget Sound Energy, Inc. (PSE) Data Access FAQ
How do C&I customers get interval data from PSE?▾
Commercial customers access 15-minute and hourly interval data through the EnergyCAP platform, which replaced the legacy MyData system. EnergyCAP supports CSV export and a REST API. Nectar also provides PSE billing and interval data via API with customer authorization — see docs.nectarclimate.com.
Does PSE support EDI for billing and meter data?▾
No. PSE does not offer customer-facing EDI for 814, 810, 867, or 820 transactions. Its only EDI-style support is OASIS for wholesale transmission. For programmatic customer data, use the EnergyCAP API or Green Button exports.
How does a third party get authorized to access PSE data?▾
The customer completes a PSE Customer Data Release Form (account number, service address, name on bill) or invites the third party as a user in EnergyCAP with a Viewer, Editor, or Admin role. Washington UTC rules require explicit customer permission, revocable at any time.
What rate schedule applies to my commercial facility?▾
Small commercial sites under 50 kW typically take Schedule 24; sites at 50 kW and above take Schedule 26 with demand charges; large industrial loads use high-voltage schedules with voltage discounts. Demand level and service voltage drive the choice.
Does PSE support Green Button Connect My Data?▾
PSE supports the Green Button ESPI XML standard primarily through manual Download My Data. Automated Connect My Data (machine-to-machine) sharing is not broadly available, so most automated access goes through EnergyCAP or Nectar's API (docs.nectarclimate.com).
How far back does PSE billing and usage data go?▾
The online portal provides up to 24 months of billing history. Interval and consumption history in EnergyCAP typically spans 12-24 months depending on account age and meter installation date.
