ERock designs, assembles, deploys, and maintains modular distributed natural gas power systems. Its primary product, the RockBlock, is a modular generator string that scales in 0.5 MW increments to provide between 1.5 MW and 3.5 MW of power. These units convert pipeline natural gas into electricity and are sold as integrated solutions with the Granite software platform for real-time monitoring and dispatch. ERock targets three use cases: bridge power for facilities waiting for grid interconnection, backup power for mission-critical sites, and dispatchable power for grid stability. Customers include data center operators, electric utilities, and large commercial businesses. The company generates revenue through fixed-price equipment sales and long-term operations and maintenance services, with contracts typically lasting 5 to 15 years. ERock operates an asset-light model by selling rather than leasing its systems. While present in nine states, the company derives 83% of its revenue from Texas and 8% from California. ERock's growth strategy focuses on expanding its manufacturing capacity at the Titan and Hyperion facilities to fulfill a backlog concentrated in the data center sector. The company uses a land-and-expand approach, growing pilot programs into large-scale deployments for retailers and utilities.
