Project : Gaston County Landfill Gas-to-Energy Project

Gaston County -- Gaston County, North Carolina

CHA planned and designed this $10.5 million 6 MWE landfill gas-to-energy project, which included the installation of over 70 gas extraction wells, collection system infrastructure, blower/flare, gas compression and cleanup, a 6,000-foot gas transmission system, and a power generation facility.

The power generation facility includes three engine generators with room to accommodate a fourth. The generators are housed in an enclosed building that includes a rooftop solar voltaic panel array, a supervisory control and data acquisition (SCADA) center, and administrative support facilities. Energy generation is expected to reach an ultimate capacity of approximately 50,000 megawatt-hours per year.

We secured all required agreements and permits for this project, including a multi-year purchase power agreement (PPA) bundled with renewable energy credits (REC) sales. We also solicited and evaluated proposals to monetize verified emissions reductions (VERs) resulting from the destruction of landfill methane, and we assisted Gaston County in the negotiation of a multi-year purchase agreement.

The project has reduced greenhouse gas emissions by over 250,000 metric tons of CO2e. In addition, revenue is generated from the monetization of carbon credits, RECs, and electric energy sales. The average annual electric energy and REC revenue for the term of the PPA is projected to be approximately $3,675,000/year. On an annual basis, Gaston County will also receive an additional $500,000 to $700,000 per year from the sale of carbon offsets under the existing VERPA.
