Carroll EMC does not publish an official REST API or developer portal. The NISC SmartHub platform it uses has been reverse-engineered by open-source projects (e.g., electric-usage-downloader) to retrieve 15-minute interval data, but this is unofficial, for personal use only, and could be disabled at any time. For commercial needs, the recommended paths are member-mediated Green Button downloads or a licensed data aggregator.

Rate Schedules & Tariff Analysis
Carroll EMC's commercial pricing splits into a demand-based General Service schedule (GS-4) for larger accounts and a flat-energy Small Commercial schedule (SC-4) for accounts under 50 kVA. GS-4 uses a low explicit $2.00/kW demand charge but recovers most cost through tiered, declining-block energy rates and a 15-minute demand basis, with reactive-demand penalties for low power factor. A Wholesale Power Component / PCA reconciles wholesale costs in later schedules.
Carroll Electric Membership Corporation (Georgia) Rate Schedule List
| Schedule | Applicability |
|---|---|
| Schedule GS-4 General Service | Demand-based tiered-energy rate for larger C&I accounts |
| Schedule SC-4 Small Commercial | Flat $0.1325/kWh energy rate for accounts under 50 kVA |
Carroll Electric Membership Corporation (Georgia) Rate Features & TOU Details
- GS-4 demand based on highest 15-minute measurement
- Declining-block energy tiers reward high load factor

- SC-4 is a simple flat $0.1325/kWh for accounts under 50 kVA
- Wholesale Power Component / PCA reconciles wholesale power costs
- e-Bill and EFT riders each give a $2.50/mo discount

Carroll Electric Membership Corporation (Georgia) Data Access FAQ
How can a Carroll EMC commercial or industrial member get their interval data?▾
Log into the SmartHub Member Portal at myaccount.carrollecc.com, open "Usage History," and click "Green Button Download My Data" to export up to 14 months of usage as a zipped ESPI/Atom XML file. Daily data is standard, with hourly available on supported smart meters. There is no Green Button Connect or official API.
Does Carroll EMC offer a third-party data API or Green Button Connect?▾
No. Carroll EMC supports Green Button Download My Data only. There is no Green Button Connect (OAuth) and no official REST API. Third parties should rely on member-mediated downloads or on Nectar, which provides API access to this utility's billing data — see docs.nectarclimate.com.
What rate applies to a Carroll EMC commercial or industrial account?▾
Larger commercial and industrial accounts are billed on Schedule GS-4 (General Service), which has a $90.00 monthly service charge, a $2.00/kW demand charge, and tiered energy charges starting at $0.1545/kWh. Smaller accounts with less than 50 kVA installed capacity use Schedule SC-4 (Small Commercial) at a flat $0.1325/kWh plus a $39.00 service charge. Rates are effective February 1, 2025.
How is demand measured on the Carroll EMC GS-4 rate?▾
Demand is based on the highest 15-minute measurement during the billing month. The GS-4 minimum charge is the highest of $90.00 plus $7.00/kW above 5 kW, $1.00 per kVA of required transformer capacity, or a contract-specified amount. Excess reactive demand (low power factor) is billed at $0.30 per excess kVAr.

Not via a utility-run program. The best supported paths are to have the member download and share their Green Button XML, or to use Nectar, which provides API access to this utility's billing data — see docs.nectarclimate.com.
