Virtual Peaker is a Louisville, Kentucky software company selling grid-edge DERMS and virtual power plant software to United States and Canadian electric utilities — investor-owned utilities, municipal utilities, and rural electric cooperatives. Its platform is sold as three suites: Shift (grid-edge DERMS device control and demand response event dispatch), Relay (customer engagement, enrollment, and incentive processing), and Envision (demand forecasting). Virtual Peaker sits in the private DER-orchestration layer of the energy value chain, between device OEMs behind the meter and the utility back office — it is a vendor, not a utility, not a retailer, and not a data holder, so no consumer energy data right attaches to it. There is no Green Button / ESPI implementation here, no Consumer Data Right obligation, and no open market or grid data of any kind. What it does publish is its own API specification: Gravity Connect, an OpenAPI 3.0.0 contract (v2.0.6) that Virtual Peaker authored and openly published as a vendor-agnostic alternative to OpenADR and IEEE 2030.5 for onboarding and controlling DER devices. Gravity Connect is two-sided — the device OEM implements one half, the VPP platform implements the other — and both halves are readable anonymously as full Redoc API references. The honest posture: a real, downloadable, standards-ambitious API contract that is effectively undiscoverable (it is linked from nowhere on the marketing site) and whose credentials are partner-only, issued per utility program by emailing the Gravity Connect team. The commercial Shift API is named and sold on the marketing site but has no public documentation at all.
