Mainspring Energy

Mainspring’s factory-built, modular systems can be installed and commissioned in months, not years. This allows new facilities and expansions to add capacity without waiting for delayed grid interconnections or substation upgrades. The result is faster time-to-power for both hyperscale and colocation operators.

Each unit operates independently and can start and ramp in seconds. Modularity enables low-cost redundancy, ensuring that maintenance on one generator does not interrupt operations. Systems can operate in parallel with the grid, in islanded mode during outages, or fully islanded without a grid connection.

Mainspring’s non-combustion reaction produces near-zero NOx and no particulate matter, meeting the strictest air-quality standards without after-treatment. This simplifies permitting and enables deployment in regions where traditional engines or turbines are restricted. Because there is no after-treatment, there is no risk of falling out of compliance over time.

The linear generator operates on natural gas, biogas, propane, or hydrogen, seamlessly switching between them without downtime. This provides true fuel redundancy, allowing data centers to maintain operation using stored fuels during gas interruptions and return to pipeline gas when available without retrofit or permanent conversion.

Mainspring delivers firm, dispatchable, low-emission power at high efficiency. With the ability to seamlessly switch to lower-carbon fuels, data center operators can firm intermittent renewables while meeting baseload power requirements and advancing toward net-zero commitments.
