Interval Data & Smart Meters

CoServ deployed AMI smart meters system-wide, enabling 15-minute interval data for electric service through SmartHub usage tools (Usage Explorer, Usage Comparison, Average Usage). For gas service, usage is recorded at monthly meter-read frequency; CoServ Gas customers do not generally have 15-minute gas interval data.

Meter Technology
Two-way wireless RF AMI network (electric); standard mechanical gas meters read monthly for gas service.
Electric Granularity
15-minute (electric AMI, affiliate service)
Gas Granularity
Monthly meter-read (gas)

How to Download CoServ Gas Ltd. Interval Data via Green Button

  2. 02Open Usage Explorer and set a custom date range
  3. 03Click Green Button Download to export ESPI-standard XML

Rate Schedules & Tariff Analysis

CoServ Gas C&I bills are driven primarily by the volumetric usage charge per Ccf, which is dominated by the monthly Purchased Gas Factor (PGF) — the pass-through of wholesale gas cost. The fixed customer charge ($40/meter + $8.04 IRA rider) is modest, and the Weather Normalization Adjustment (WNA) smooths weather-driven swings. Because the PGF moves monthly (e.g., +$1.25/Ccf in May 2026 vs +$1.15 in April 2026), commodity cost is the main lever for C&I gas spend.

Commercial Gas RateCommercial gas customers — $1.3501/Ccf all-in May 2026.
Public Authority Gas RatePublic authority gas customers — $1.3725/Ccf all-in May 2026.

Limitations & Considerations

  • Gas service is metered monthly — true 15-minute gas interval data is not generally available (15-minute data applies to electric AMI service).
  • Green Button export support specifically for gas customer data should be confirmed with CoServ.
  • The SmartHub REST API has no public self-service developer portal; credentials are issued by CoServ after LOA authorization.
  • No documented EDI trading-partner program for CoServ Gas.
  • Green Button Connect My Data (automated ESPI sharing) is not confirmed as implemented.

CoServ Gas Ltd. Data Access FAQ

How does my C&I business get gas usage data from CoServ Gas?

Register your account in SmartHub at coserv.smarthub.coop to view monthly bills and usage. CoServ Gas meters are read monthly, so gas usage is reported at monthly granularity rather than 15-minute intervals. You can download bill PDFs and export usage via Green Button XML for analysis.

Can an energy consultant or broker access our CoServ account on our behalf?

Yes. CoServ uses a Letter of Authorization (LOA) process. Complete the LOA on company letterhead with your FEIN and Secretary of State filing, have an officer sign it, and email it to CoServ. After approval (typically 5-10 business days) the authorized representative can register in SmartHub. There is no fee.

Does CoServ Gas support an API for automated data integration?

The underlying SmartHub platform exposes a REST API (JSON, API-key auth) documented at apidoc-en.smh.smarthing.com. Access requires customer authorization via LOA and API credentials issued by CoServ — there is no public self-service developer portal. Confirm gas data availability for your specific account.

Does CoServ Gas offer EDI for commercial billing?

CoServ Gas does not maintain a documented, publicly available EDI trading-partner program. ANSI X12 sets such as 810 (invoice) or 867 (usage) are not confirmed. Contact CoServ Customer Care (Commercial option) to inquire about any EDI capability.

How are CoServ Gas commercial rates structured?

Commercial and Public Authority gas service carries a fixed monthly customer charge plus a volumetric usage charge per Ccf, adjusted monthly by the Purchased Gas Factor (PGF) and Weather Normalization Adjustment (WNA), plus an interim rate adjustment rider. See the Tariff for Gas Service for the full schedule.
