Generate LFG Electricity for Electric Vehicles

  • Back to Toolkit for Expiring LFG Electricity PPAs
  • Back to Electricity-Related Options

As the demand for cleaner sources of transportation fuel increases, electricity from landfill gas (LFG) can be sold into transportation fuel markets or stored for electric vehicle (EV) charging stations.

Van Warmerdam Dairy, California 2, 3, 4

Van Warmerdam Dairy in Galt, California has had a covered lagoon digester in operation since July 2013. Each year, the anaerobic digester system generates enough biogas to produce about 1,760,000 kilowatt-hours of electricity from the manure of more than 1,000 cows—enough to power nearly 5,180,000 miles driven by electric car. Third-party project owner/developer Maas Energy Works pays a monthly lease to the dairy for use of the site and the manure, and sells the electricity generated from the biogas to Sacramento Municipal Utility District (SMUD) under a 20-year PPA.

In 2019, SMUD applied for a dairy manure biogas-to-electricity pathway under California’s LCFS. California’s LCFS was adopted in 2009 with the goal of reducing greenhouse gas emissions by incentivizing the use of transportation fuels with a lower carbon intensity than the baseline. Providers of alternative transportation fuels such as electricity, hydrogen or biogas can generate LCFS credits by opting into the LCFS as a regulated party.

Under their biogas-to-electricity pathway, the electricity generated from Van Warmerdam’s digester project is still sold to SMUD, but it is used to power electric vehicle charging stations within their service territory which allows the project to generate LCFS credits. SMUD uses the revenue from these credits to fund transportation electrification to benefit EV drivers in California.

Criteria:

  • Project is in an area with favorable low-carbon transportation fuel policies such as California’s Low Carbon Fuel Standard (LCFS) and Oregon’s Clean Fuels Program.
  • If an energy storage component is included, project is in an area with favorable policies such as behind-the-meter storage or net metering for grids that connect to larger grids.

Pros:

  • EV charging stations can be located conveniently near the source of the LFG electricity as part of their regular routing, e.g., garbage fleets routinely visit a landfill and would not have to drive separately to get charged.
  • Some state crediting programs allow for additional incentive credits for electricity used in EVs even when the charging station is not adjacent to the LFG electricity project.

Cons:

  • Administrative process of registering the project and trading credits may be burdensome to the LFG electricity project owner.

Economic Considerations:

  • Revenue from state-level low-carbon transportation fuel programs if electricity can be wheeled for vehicle use in that state. Credit revenue can be shared between project partners to increase profitability of project.
    • See average credit prices on the LCFS Credit Transfer Activity Reports page.
  • EV charging station costs vary depending on the charging level and type – equipment costs range from $300 to $40,000 and installation costs range from $600 to $51,000.1 Costs are expected to decrease as the demand for EV chargers increases. Incentives may also be available to offset costs for EV charging.
    • Charging stations may also benefit from energy storage to avoid charging during peak electrical rate times. However, additional costs for storage would be required.
