See the Greenville Utilities Commission Rate Schedules & Tariff Guide →Interval Data & Smart Meters
GUC currently uses Automated Meter Reading (AMR, in service since 2004) with monthly drive-by collection, so no true 15/30-minute interval data is available today. GUC's board authorized a $41.7M Sensus FlexNet AMI program (March 2026 resolution) deploying ~141,000 meters over five years (2026-2031), which will add two-way communication and a consumer-facing real-time usage portal. Interval data access is expected post-2027 as deployment progresses.

The only third-party access path is manual portal account delegation by the primary account holder. The underlying Oracle Customer Cloud Service platform supports APIs and web services, but GUC has not exposed them externally.

Rate Schedules & Tariff Analysis
GUC's nonresidential rates are demand-tiered. The defining feature for large C&I customers is the EG-4 coincident-peak (CP) structure: the demand charge ($23.90/CP kW) applies only to the customer's load during the single NCEMPA system peak interval each month. This makes peak-hour curtailment far more valuable than at flat-demand utilities, since shaving load during the one CP event directly cuts the demand bill. Energy at 3.082 cents/kWh on EG-4 is low because demand and wholesale costs are unbundled into the CP and PPA components.
Greenville Utilities Commission Rate Schedule List
| Schedule | Applicability |
|---|---|
| EG-2 Medium General Service | 35-750 kW; flat $4.17/kW demand and 8.975 cents/kWh energy. |
| EG-4 Large General Service-CP | >=750 kW; CP demand $23.90/kW, NCP $10.92/kW, energy 3.082 cents/kWh. |
| EG-6 Transmission Service-CP | Transmission-level large industrial customers. |

Greenville Utilities Commission Data Access FAQ
Can a third-party energy manager or consultant access our GUC usage data?▾
Yes, through portal account delegation. The primary account holder logs into myaccount.guc.com, adds the third party by email, and grants Visitor (read-only) or Account Holder (full) access. There is no Share My Data portal or API, so delegation is the only third-party path today.
Does GUC offer interval (15-minute) data for C&I load analysis?▾
Not yet. GUC reads meters monthly via AMR. True interval data is expected as the Sensus FlexNet AMI program rolls out from 2026 through 2031, with a consumer-facing real-time usage portal anticipated post-2027.
Is Green Button or an API available for automated data feeds?▾
No. GUC has not implemented Green Button Download/Connect My Data, a public API, or ESPI. The Oracle Customer Cloud Service platform supports these capabilities, but GUC has not exposed them publicly. For bulk or integration needs, contact procurement at haddocgc@guc.com.
How are large C&I customers billed, and how can demand charges be reduced?▾
Large customers (>=750 kW) fall under Schedule EG-4 Large General Service-CP, which bills a coincident-peak (CP) demand charge tied to the NCEMPA wholesale peak. GUC issues advance CP-event notifications; curtailing load during those windows directly reduces the CP demand charge. Mid-size customers (35-750 kW) use EG-2 with a flat $4.17/kW billing demand charge.
Who do we contact for EDI or system integration?▾
GUC has no formal EDI trading partner program. Direct inquiries to Customer Service (252-752-7166) and ask for the Key Accounts Team, or contact Procurement at haddocgc@guc.com / 252-551-1533.
