Rate Schedules & Tariff Analysis
ECE's commercial rate design follows a standard cooperative structure: a fixed cost-of-basic-service charge covering poles/wires/transformers/metering, a per-kWh energy charge, and (for General Service at 50 kW+) a per-kW demand charge. The 50 kW threshold between SGS and GS is the key structural pivot, with three-month/12-month hysteresis rules to prevent rate flapping. A variable Power Cost Adjustment passes through wholesale power costs from Great River Energy. Members with curtailable load can lower costs via the C&I Interruptible rate. Exact 2026 commercial dollar figures are published only in ECE's PDF rate schedules.
East Central Energy Rate Schedule List
| Schedule | Applicability |
|---|---|
| Small General Service (SGS) | Non-residential, demand under 50 kW |
| General Service (GS) | Non-residential, demand 50 kW+ |
| C&I Interruptible Service | Members with ~50 kW+ controllable load |

East Central Energy Data Access FAQ
Can a commercial member pull 15-minute interval data from East Central Energy?▾
Yes. ECE's AMI meters collect 15-minute interval data, and any SmartHub member can use Green Button Download My Data to export up to 14 months of interval usage as ESPI-standard XML (zipped) at no charge. This is the recommended path for energy analysis, solar design, and benchmarking in tools like ENERGY STAR Portfolio Manager.
Which rate schedule applies to my business?▾
ECE assigns non-residential members by demand: Small General Service (SGS) for metered demand under 50 kW, and General Service (GS) when demand is 50 kW or greater for at least three consecutive months. A Commercial & Industrial Interruptible Service (C&I) rate is available to members maintaining ~50 kW of controllable load. ECE reviews each business's usage annually and may recommend a lower-cost rate — a free service via 1-800-254-7944.
How can my energy consultant or Nectar access my ECE data?▾
The cleanest path is to add the consultant as a SmartHub Authorized User (ECE requires an NDA for any third party receiving member information), or to export your Green Button XML and share it directly. ECE has no public API; for automated access, Nectar provides API access to this utility's billing data — see docs.nectarclimate.com — or call Business Accounts at 1-800-254-7944.
Does East Central Energy support Green Button Connect My Data (automated sharing)?▾
The underlying NISC SmartHub platform supports the Green Button Connect My Data (CMD) framework with OAuth 2.0, but ECE has not confirmed an active, advertised CMD program. Confirmed today is Green Button Download My Data (manual export). Confirm CMD availability with ECE at 1-800-254-7944 before relying on automated authorization.
Where can I see the exact commercial rates and demand charges?▾
ECE publishes its 2026 SGS and GS rate schedules and the C&I rate schedule on the Charges & Fees (Commercial) page; rates changed effective January 2026. The page links the current PDFs and notes that every commercial account pays a cost-of-basic-service charge plus per-kWh energy and (for GS) demand charges. For an exact quote, ECE invites businesses to call 1-800-254-7944 for personalized rate information.
