Corn Belt Energy's AMI smart meters capture hourly interval data accessible two ways: interactive viewing in SmartHub (daily, hourly, monthly with temperature overlay and event markers) and Green Button Download My Data, which exports up to 14 months of hourly readings as NAESB ESPI-compliant XML in a ZIP file. There is no native CSV export; analysts parse the XML or upload it to Green Button-compatible tools.
How to Download Corn Belt Energy Corporation Interval Data via Green Button
- 01Log into https://cornbeltenergy.smarthub.coop/
- 02Click My Usage in the main menu
- 03Click the Green Button Download My Data button
- 04Select start/end dates (up to 14 months back) and the service point
- 05Click Download Usage Data to receive a ZIP of XML files

Interval data is essential for rate comparison and TOU analysis.

No public developer portal, API keys, or aggregator registration exists at the cooperative. Programmatic access reduces to Green Button XML downloads (customer-mediated) and statute-backed authorization requests. Nectar provides API access to this utility's billing and interval data — see docs.nectarclimate.com — but Corn Belt Energy has not confirmed Green Button OAuth or a utility-operated data-sharing API.

EDI (Electronic Data Interchange)
No EDI trading partner program (814, 820, 867, 997) is published. As a not-for-profit cooperative outside Illinois' retail choice market (which covers ComEd and Ameren territories), Corn Belt Energy does not support supplier switching via EDI. Requests for structured meter data are typically routed to SmartHub downloads or custom reports; generation/transmission-level EDI questions may be referred to Wabash Valley Power Alliance.

Corn Belt Energy Corporation Data Access FAQ
How do I download hourly interval data from Corn Belt Energy?▾
Log into SmartHub at https://cornbeltenergy.smarthub.coop/, open the My Usage tab, and click Green Button Download My Data. Select up to 14 months of history and download a ZIP of NAESB ESPI-compliant XML containing hourly kWh intervals with UTC timestamps. Parse it in Excel Power Query, Python, or any Green Button-compatible tool - there is no native CSV export.
Can a consultant or aggregator access a member's Corn Belt Energy data?▾
Yes, two ways. Fastest: the member downloads the Green Button XML and shares it directly. Formal: under Illinois 220 ILCS 5/16-122, the member signs an authorization naming the third party, which submits it with business credentials to Member Services (309-662-5330); the cooperative responds in 5-10 business days with email delivery, temporary portal access, or a bulk export.
Does Corn Belt Energy offer an API or Green Button Connect?▾
No public API or developer portal exists, and Green Button Connect My Data (OAuth-based recurring sharing) is not confirmed. The NISC SmartHub platform can support it, so ask the cooperative directly. Today, programmatic access means Green Button XML downloads plus statute-backed authorization requests.
Does Corn Belt Energy support EDI for supplier switching or meter data?▾
No. The cooperative sits outside Illinois' retail choice market (which covers only ComEd and Ameren territories), so there is no 814/820/867 EDI program. Structured data needs are handled via SmartHub downloads or custom reports from Member Services.
Can C&I members shop for a competitive electricity supplier?▾
No. Illinois retail choice does not extend to rural cooperatives; all Corn Belt Energy members take bundled service with wholesale power from Wabash Valley Power Alliance. Cost optimization instead focuses on time-of-use alignment (4-8 PM peak), demand response, and rate selection.
How much history does Corn Belt Energy retain?▾
SmartHub shows 13 months of billing history and up to 14 months of hourly interval data via Green Button download. Longer-term analysis requires an archival data request through Member Services at 309-662-5330, which may carry a reasonable fee under Illinois statute.
