Linear generators for onsite power
Mainspring Energy makes linear generators that produce onsite electricity and can switch between fuels, giving customers local generation that adapts as fuel availability and prices change. The company began commercial shipments in 2020 and now has hundreds of megawatts in advanced development and field operations for Fortune 500 companies, data centres and utilities — data centres being the demand that has made onsite generation urgent, since grid interconnection queues now run years. Mainspring partners with global energy leaders including AEP, NextEra Energy Resources and Schneider Electric.
