Profile
Sells modular natural-gas power systems with design and installation, then provides operations, maintenance and asset-management services. Customer-owned systems bridge delayed grid connections, provide outage backup and offer dispatchable capacity to utilities and power markets.
Designs, deploys and services modular onsite power systems built around quick-response natural-gas generators and embedded Granite software. RockBlock systems can supply bridge power before grid interconnection, maintain critical loads during outages, or dispatch capacity in response to utility and power-market signals. Sales combine equipment with fixed-price design, construction and commissioning, followed by operations, maintenance and asset-management contracts.
Works with data centers, utilities and commercial-and-industrial sites across U.S. power markets, with its largest operating footprints in California and Texas. The ERock Platform brings engineering, installation, commissioning, network operations, maintenance and market settlement together; telemetry supports monitoring, predictive diagnostics and remote dispatch. Deployment depends on pipeline gas, electrical interconnection, permits, tariff rules, component suppliers and the ramp-up of in-house assembly.
