LFGcost-Web — Landfill Gas Energy Cost Model

On this page:

Background

LFGcost was initially developed in 2002 to help stakeholders estimate the costs of an LFG energy project. LMOP routinely updates the tool to reflect changes in the LFG energy industry. In 2015, LMOP undertook a peer review of LFGcost-Web, Version 3.0. For more information on the peer review, see the Emission Guidelines and Compliance Times for Municipal Solid Waste Landfills rule docket Exit(Docket ID# EPA-HQ-OAR-2014-0451-0210). See more information about LFGcost-Web’s version history and peer review.

What's New

LFGcost-Web, Version 3.5, replaced Version 3.4 in March 2021. Significant revisions between Version 3.5 and Version 3.4 include:

  • Updated the economic benefits analysis for reciprocating engine and direct-use projects and added a new economic benefits analysis for renewable natural gas (RNG) projects. The RNG project economic benefits build on the updates made to the RNG cost calculations in the model in October 2020.
  • Removed the leachate evaporator project type from the model given its outdated cost basis.

Project Types

LFGcost-Web allows users to choose from 11 LFG energy project types and gives users the option of including costs for a new gas collection and flaring system.

LFG Energy Project Types
Direct-use system (boiler, greenhouse, etc.)
Boiler retrofit
RNG processing plant (upgrading gas to pipeline quality)
Onsite compressed natural gas (CNG) production and fueling station
Electricity generation – Standard turbine-generator sets
Electricity generation – Standard reciprocating engine-generator sets
Electricity generation – Microturbine-generator sets
Electricity generation – Small reciprocating engine-generator sets
CHP – Reciprocating engine-generator sets
CHP – Turbine-generator sets
CHP – Microturbine-generator sets

Model Outputs

The model calculates LFG generation profiles based on landfill characteristics and other user inputs and then determines various project-specific outputs.

Primary Model Outputs
Design and average project sizes
Total installed capital cost for year of construction
Annual costs for initial year of operation
Internal rate of return
Net present value at year of construction
Years to breakeven
Amount of methane collected and destroyed
Greenhouse gas value of amount of methane utilized by project
Amount of carbon dioxide from avoided energy generation
Optional Model Outputs (for standard reciprocating engine-generator, direct-use and RNG projects)
Jobs created within the state (construction phase and operating phase)
Earnings impact within the state ($000, construction phase and operating phase)
State-wide economic output ($000, construction phase and operating phase)

The default inputs and costs that are estimated by LFGcost-Web are based on typical project designs and for typical landfill situations.
