Carroll Electric does not publish an official customer-data API. The NISC SmartHub backend exposes an undocumented REST API that community tools use to retrieve 15-minute interval data with the account owner's credentials. It is not officially supported and may be subject to SmartHub terms of service; for production C&I integration, contact NISC/Carroll Electric for official access.

Rate Schedules & Tariff Analysis
For C&I members, the key lever is matching demand level to the correct rate class. Energy rates step down sharply as demand class rises (12.056¢ small commercial vs. 7.208¢ on Rate 4), while demand charges and the availability charge rise. Rate 14 offers a coincident-peak design that can favor loads able to reduce demand during the cooperative's system peak. All energy charges float with the wholesale power cost adjustment.
Carroll Electric Cooperative Corporation Rate Schedule List
| Schedule | Applicability |
|---|---|
| Rate 2 - Three-Phase (<100 kW) | Three-phase commercial under 100 kW; tiered energy, no demand charge. |
| Rate 3 - Demand 100-250 kW | Mid-size C&I; seasonal demand charge, 8.004¢/kWh. |
| Rate 4 - Large Commercial (>250 kW) | Large C&I; lowest energy rate (7.208¢/kWh) but highest demand charge. |
| Rate 14 - Optional Coincident Demand (>50 kW) | Optional coincident-peak design for >50 kW loads that can curtail at system peak. |
Carroll Electric Cooperative Corporation Rate Features & TOU Details

Carroll Electric Cooperative Corporation Data Access FAQ
How does a commercial customer download billing data from Carroll Electric?▾
Register a commercial login at MyAccount (myaccount.carrollecc.com) or SmartHub, open the Bill & Pay tab, and download itemized bills as PDF. For multi-site portfolios, link accounts under one login. Custom or bulk historical exports can be requested at 1-800-432-9720.
Can a third-party energy consultant get automated access to our data?▾
There is no documented formal third-party API (Connect My Data / Share My Data) program. In practice, access is customer-mediated: the account owner shares portal access or downloads bills and Green Button/usage files to send to the consultant. A written authorization request can be made by calling 1-800-432-9720.
Is 15-minute interval data available for C&I sites?▾
AMI meters store 15-minute interval data in the NISC backend. Standard portal/CSV export currently provides hourly granularity (15-minute CSV export ended in January 2024), but 15-minute data can be retrieved via the undocumented SmartHub API used by community tools.
Which rate class applies to a large commercial or industrial facility?▾
Loads over 250 kW are served under Rate 4 (7.208¢/kWh energy plus $12.15-$15.78/kW demand). Loads of 100-250 kW fall under Rate 3 (8.004¢/kWh plus $9.12-$12.16/kW). Peak-flexible loads over 50 kW may elect optional Rate 14, which uses a coincident-peak demand charge.
Does Carroll Electric support EDI for C&I billing data?▾
No customer-facing EDI program is publicly documented. The cooperative uses the NISC iVUE billing system; C&I customers needing EDI 814/867 metered data should contact Business Operations at 1-800-432-9720 to ask whether trading-partner EDI is available.
Can we shop for a competitive electricity supplier?▾
No. Arkansas does not have retail electric choice, and Carroll Electric is a member-owned cooperative with an exclusive service territory. Rates are board-approved and filed with the Arkansas PSC, with a wholesale power cost adjustment applied to energy charges.
