What Generac Grid Services does

Generac Grid Services is a private subsidiary of Generac Power Systems (NYSE: GNRC) that provides an open, cloud-native distributed energy resource management system (DERMS) and virtual power plant (VPP) platform under the Concerto brand. The platform orchestrates heterogeneous DERs — generators, batteries, solar inverters, EV chargers, smart thermostats, and water heaters — across real-time grid services including demand response, frequency regulation (aFRR), capacity markets, distribution optimization, and resilience events. Concerto is built on AWS cloud infrastructure, supports a broad set of industry protocols (OpenADR 2.0b, IEEE 2030.5, IEC 61850, IEC 60870-5-104, DNP3.0, Modbus, CTA-2045, ICCP, BACnet), and is engineered for 100,000+ asset fleets with 2-second closed-loop control, >99% dispatch accuracy, and 99.9% uptime.

The company sells primarily to utilities, energy retailers, and large commercial & industrial energy consumers through an enterprise field sales motion supported by an SDK and 60+ technology integration partners. Revenue derives from a combination of software licensing / SaaS subscriptions for the Concerto platform, professional services for end-to-end program delivery, and hardware sales of Generac backup generators, batteries, EV chargers (including Wallbox), and other DERs flowing through Generac's ~8,700-dealer US network. Notable customers include RWE (Germany), Iberdrola (Spain), Dominion Energy Virginia, Arizona Public Service, Alectra Utilities, DEWA (Dubai), AGL Energy (Australia), Eversource, and Pearlstone Energy (UK), with operations spanning North America, Europe, the Middle East, and Asia Pacific.

In 2023 alone, Generac Grid Services delivered more than 34 GWh of capacity to the grid across 2.5 million DER dispatches from 20,500+ devices, was selected for up to $440 million in DOE Puerto Rico Energy Resilience Fund vendor negotiations, received a $50 million DOE GRIP grant for Massachusetts, made strategic minority investments in Wallbox (NYSE: WBX) and Rolling Energy Resources, and in early 2024 formed a DERMS collaboration with Smarter Grid Solutions (a Mitsubishi Electric group company). Headcount is reported at 11–50 employees, with offices in Denver, Vancouver, and Waukesha (parent headquarters).

Revenue model

1. Software licensing / SaaS (Concerto DERMS/VPP platform): Concerto is offered as a licensed software platform — either standalone or as an integrated module of a partner's utility DERMS platform (e.g., SGS Strata Grid). Deployed globally via cloud (AWS) with subscription or usage-based pricing. Enables capacity markets, frequency regulation, reserves, and distribution optimization services.
2. Professional services and program management: End-to-end services including program design, marketing, customer acquisition, asset installation/configuration, program management, measurement and verification, end-customer support, and incentive disbursement. Full-service performance contracts enable utilities to pay for capacity without operational involvement.
3. Hardware sales (Generac and partner devices): Generac sells backup generators, batteries, smart thermostats, and other DER hardware through its ~8,700-dealer network. EV charging hardware (Wallbox, ChargePoint) and solar+storage solutions generate incremental hardware revenue. Devices serve as the managed assets within Concerto VPP programs.
