- Economic dispatch based on tariff or real-time pricing
- Peak-load shaving for demand charge reduction
- Onsite solar and energy storage firming
For utilities, municipalities, and power project developers, Mainspring’s Linear Generators offer utility-scale performance at distributed scale. The low emissions and modularity of Mainspring’s products reduces the permitting and stranded asset risks associated with large generation and transmission projects.
- Meet capacity needs with a distributed network of systems that alleviate congestion constraints, firm renewables, and add local resiliency
- Avoid or defer T&D upgrades by placing high-performance, flexible capacity with precision
- Charge electric vehicle (EV) fleets while avoiding expensive and multi-year system upgrades
The Mainspring Linear Generator is the ideal backbone for any microgrid. Our products can seamlessly integrate with solar, energy storage, and microgrid controllers to provide load balancing while grid parallel or islanded from the grid.
- Municipal infrastructure
- Hospitals and healthcare facilities
- Shipping ports
- Data centers
- University campuses
- Military bases
- Residential communities
We currently offer customers two purchase options to realize the cost, resilience, and sustainability benefits of Mainspring’s Linear Generators, a direct capital purchase or an energy services agreement (ESA). Both options come with a Mainspring-supported Maintenance Agreement.
Customers looking to maximize cost savings and return on investment can directly purchase and own a Linear Generator. Mainspring works with customers to facilitate the installation, providing installation support or delivering full turn-key projects.
Energy Services Agreement
Mainspring has partnered with NextEra Energy Resources to provide customers a financing option for turn-key Linear Generator projects. With our Energy Services Agreement, customers can realize immediate cost savings, with no upfront costs, by only paying for electricity produced over the term of the agreement.
