ACEC has no public developer portal, REST API, aggregator partnerships (Urjanet, PowerAdvocate), or Share My Data consent system. Nectar provides API access to this utility's billing and interval data — see docs.nectarclimate.com. Otherwise, the practical third-party path is customer-exported Green Button CSVs shared via secure transfer. Community tools have reverse-engineered the SmartHub API (Home Assistant integration, InfluxDB downloader) using customer credentials, but these are unofficial and unsupported.
How to Register as a Adams-Columbia Electric Cooperative (ACEC) API Vendor
- 01Have the customer export the full 12-14 month Green Button CSV history from SmartHub
- 02Receive the CSV via encrypted email or secure file sharing under a data processing agreement
- 03For ongoing monitoring, establish a monthly customer export routine
- 04For special requests, have the customer send written authorization to acec@acecwi.com
- 05Pull published rate schedules from the OpenEI U.S. Utility Rate Database
EDI (Electronic Data Interchange)
ACEC publishes no EDI transaction support for commercial customers or trading partners. Its NISC CIS may support EDI on the backend, but nothing is exposed externally. As a smaller member-owned cooperative, ACEC likely does not maintain trading partner infrastructure — confirm by emailing acec@acecwi.com or calling (800) 831-8629 (expect 5-10 business days for a response).

Adams-Columbia Electric Cooperative (ACEC) Data Access FAQ
How do commercial members get interval data from Adams-Columbia Electric?▾
Log into SmartHub (https://acecwi.smarthub.coop/), open My Usage > Usage Explorer, select kWh, kW, or both, and click Green Button Download My Data at the bottom of the page. Choose your date range and CSV format — you get a zipped CSV with 15-minute interval data covering roughly 12-14 months.
Does ACEC support Green Button Connect My Data for automated third-party access?▾
No. ACEC implements only Green Button Download My Data (manual CSV export). There is no CMD authorization portal, OAuth flow, or API — consultants must work from customer-exported CSVs, ideally on a monthly export routine for ongoing projects.
What rate options should C&I customers evaluate at ACEC?▾
Beyond standard General Service (GS), ACEC offers an optional Schedule GS-TOD time-of-day rate with on-peak, mid-peak, and off-peak pricing by season. Facilities that can shift load off-peak can cut costs; SmartHub lets you monitor usage by period to validate the switch. Rate details are at https://www.acecwi.com/time-of-day/.
Does ACEC offer EDI or an API for billing data?▾
No formal EDI program or public API is documented. ACEC's NISC backend may support EDI internally, but nothing is exposed to trading partners. Email acec@acecwi.com with a trading partner inquiry to confirm — expect 5-10 business days and, realistically, a manual-workflow answer.
How can an energy consultant access an ACEC member's data?▾
The reliable path is customer-mediated: have the member export the full Green Button CSV history and billing PDFs from SmartHub and share them securely under a data processing agreement. For utility-delivered data, the member sends written authorization to ACEC (P.O. Box 70, Friendship, WI 53934) naming your firm; format and turnaround vary.
Where are ACEC's rate schedules published?▾
As a cooperative, ACEC sets rates through its board rather than PSC tariff filings. Summaries live at https://www.acecwi.com/billing/rate-info/ and the time-of-day rate at https://www.acecwi.com/time-of-day/. The OpenEI U.S. Utility Rate Database also documents 21 ACEC rates in a standardized, machine-readable format.
