Mainspring Energy

Each linear generator ships factory-built and tested, minimizing onsite construction and interconnection work. Their modular design supports rolling commissioning, allowing portions of a site to come online faster. Near-zero emissions simplify air permitting and avoid many of the delays associated with traditional engines or turbines. Together, these attributes accelerate delivery from contract to operation.

The linear generator's low emissions allow customers to deploy more generation capacity on site in less time than comparable combustion-based systems. With near-zero NOx and no particulate matter, many air districts and jurisdictions do not subject linear generators to more onerous permit compliance and identify linear generators as a lower environmental impact technology. As such, this reduces the complexity of air permitting and allows customers to gain more capacity over shorter timelines.

Customers can add linear generators in phases, sizing deployments to actual capacity demands as they grow. This modularity supports both smaller sites and larger multi-megawatt projects. It also enables rolling commissioning, allowing portions of a project to begin operating before the full buildout is complete.

Mainspring uses one linear generator model across all applications, regardless of site size, fuel, or operating mode. This consistency simplifies manufacturing, shortens lead times, and streamlines maintenance across the fleet. It also avoids the variation common with legacy technologies that rely on multiple models and custom configurations.

For both behind-the-meter and front-of-the-meter projects stalled by interconnection or capacity constraints, Mainspring provides local power that allows projects to progress faster. As needs evolve, the linear generator’s flexibility supports applications such as firming renewables, managing peak loads, and operating on zero carbon fuels. This ensures the asset continues to deliver value well beyond the initial delay.
