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

ScheduleApplicability
Schedule 26 - Large Demand General ServicePrimary large C&I schedule, over 350 kW
Schedule 25 - Small Demand General ServiceMid-size C&I, 50-350 kW
Schedule 24 - General ServiceSmall C&I, under 50 kW
Schedule 31 / 31T - C&I GasFirm 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)
  • Strongly seasonal demand charges, higher Oct-Mar (winter-peaking system)
  • 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.
