Customer Profile: NapaSan Waste to Power

Napa Sanitation District transforms Napa County's wastewater into high efficiency, renewable electricity using a Mainspring Linear Generator - an easily replicable model for bioenergy use that reduces methane emissions while saving costs for ratepayers.

“The linear generator is an important component of our Climate Change Mitigation Plan. The addition of this Mainspring unit to our wastewater treatment plant will help us meet our clean energy goals, reduce greenhouse gas emissions, and create operational efficiencies.”

Significantly Lighter Cleanup Requirements When Compared With Fuel Cells

  1. Mainspring’s biogas input composition requirements are much lighter than those of RNG in all steps of the cleanup process
  2. As a result, depending on the project size, the cost of biogas cleanup can be up to 70% lower with Mainspring than with a typical fuel cell project.

Dispatchability Captures Value Across Seasons

The full dispatchability of Mainspring's technology allows the products to ramp up and down with biogas production levels. In contrast to baseload-only fuel cell technology, this maximizes production and revenue potential and reduces the need for flaring throughout the year.

Incentive Eligibility

Mainspring Linear Generators are ITC eligible

The Inflation Reduction Act of 2022 specifies linear generators as eligible for the 30% investment tax credit within the definition of fuel cells in Section 48 of the Federal Tax Code.

Self-Generation Incentive Program (SGIP)

California customers using biogas to power onsite operations through linear generators may qualify for state funding from the Self-Generation Incentive Program (SGIP).
