GVEC does not operate a public developer portal, Share My Data, or Connect My Data API. The MyGVEC portal runs on NISC SmartHub; an open-source community project (electric-usage-downloader) reverse-engineers the SmartHub endpoint to pull 15-minute data using a member's own credentials, but this is unofficial and unsupported by GVEC.
Available Guadalupe Valley Electric Cooperative API Endpoints
| Function | Endpoint | Method | Format |

| Interval usage poll (reverse-engineered) | services/secured/utility-usage/poll | GET | JSON |

Rate Schedules & Tariff Analysis
GVEC unbundles each C&I bill into four components: Service Availability, Delivery, Demand, and Generation & Transmission. For G-3 the G&T component is a fixed $0.085/kWh, while G-4 and G-5 pass wholesale generation cost through directly. Demand charges are tiered and assessed on the highest 15-minute kW in the cycle, making peak management the primary lever for cost control.

Guadalupe Valley Electric Cooperative Data Access FAQ
How does a C&I customer get 15-minute interval data from GVEC?▾
Commercial and large-power members request access to the WattWatch portal from a GVEC Commercial Accounts Representative at 800-223-4832. WattWatch displays 15-minute interval readings and demand profiles; export availability depends on the portal version. There is no Green Button or automated API.
Does GVEC support Green Button or a data API for third parties?▾
No. GVEC has no Green Button Download My Data, Connect My Data / ESPI, or official public API. A consultant or aggregator obtains data through a manual letter of authorization: the member authorizes access by phone, the third party submits a written request, and GVEC delivers data (PDF/email) in about 5-10 business days.
How are GVEC commercial demand charges calculated?▾
Demand charges for G-3, G-4 and G-5 accounts are based on the maximum kilowatts metered during any single 15-minute interval in the billing cycle, then priced in tiers (for example G-3 charges $2.00/kW for the first 10 kW, $5.50/kW for the next 90 kW, and $4.00/kW over 100 kW). Managing that 15-minute peak is the main way to lower the bill.
Which GVEC rate class applies to my business?▾
GVEC assigns the rate class based on your overall monthly kilowatt demand: G-3 for three-phase loads under 250 kW, G-4 for 250-1,000 kW, and G-5 for loads over 1,000 kW. GVEC meets with new C&I members to select the class; contact Commercial Accounts at 800-223-4832.
Can my business shop for a competitive electricity supplier on GVEC?▾
No. GVEC is a member-owned cooperative that opted out of ERCOT retail competition, so there is no competitive retail provider choice. Members receive bundled service at cooperative rates approved by the GVEC board.
