Mainspring Energy is a Menlo Park, California company, founded in 2010, that makes the Mainspring Linear Generator: fuel-flexible onsite power for data centers, utilities, industrial and enterprise sites. The generator can run on natural gas, biogas, propane or hydrogen. AEP signed an agreement to buy up to 1.6 GW of Mainspring generators.
Mainspring builds dispatchable onsite generators that use a linear generator design in place of combustion engines or turbines, and markets them as low-carbon power delivered on the customer's timeline.

The generator can switch between fuels including natural gas, biogas, propane and hydrogen, so sites can move to lower-carbon fuels over time.
