Bring primary power onsite with a Mainspring-powered microgrid.

Deploy quickly.

Address grid constraints with prime power and near-zero NOx to expedite air permitting.

Manage costs.

Reduce energy costs with efficient on-site generation, replacing grid purchase with more predictable power costs.

Increase resilience.

Run prime or backup power or switch between modes for high uptime and peak load management.

Increase future optionality.

Pair Mainspring power with solar, make future-ready for RNG and other renewable fuels without retrofit, and more.

Mainspring Linear Generators deliver best-in-class total cost of ownership. 

Fully dispatchable.

Can quickly ramp up and down to match power output with power demand as needed.

High efficiency.

Designed for maximum conversion of linear motion into electricity across all power levels from 0 to 100%.

Low maintenance.

Standard materials, only two moving parts, and no oil means low maintenance and high uptime.

Fuel flexible.

Seamlessly switch between natural gas, RNG, biogas, propane, and hydrogen without hardware changes.

Take charge of your power capacity.
