Aemetis Biogas signs utility pipeline interconnect agreement and closes on installation funding
In the United States (US), Aemetis Biogas LLC, a subsidiary of renewable natural gas (RNG) and renewable fuels company Aemetis Inc has announced that it has signed the Standard Renewable Gas Interconnection Agreement (SRGIA) with the Pacific Gas & Electric Company (PG&E) and funded the final US$1.2 million payment for installation of PG&E’s interconnection equipment to deliver RNG into the utility gas pipeline in Q4 2021.
The PG&E RNG interconnect equipment has already been fabricated onto modular units that are now scheduled to be delivered to the Aemetis Keyes ethanol plant and installed during the next three months.
Once the interconnection unit is completed, the RNG produced by the Aemetis Biogas Central Dairy Digester Project will be delivered into the PG&E natural gas pipeline for sale to customers throughout California (CA) as a transportation fuel.
As planned, the engineering, permitting, offsite equipment fabrication, and full payment of US$2.3 million to PG&E has been completed. PG&E manages the fabrication and installation of the interconnection system connecting the Aemetis biogas cleanup and compression facility to the gas utility pipeline. We are pleased that a significant milestone for the completion of the Aemetis Biogas Central Dairy project was completed today, said Andy Foster, President of the Aemetis Biogas.
The PG&E interconnection unit is a gateway for the network of lagoon digesters being built by Aemetis Biogas to produce renewable natural gas (RNG) for use as a transportation fuel. Aemetis has already built and currently operates two dairy biogas digesters, on-site dairy gas upgrading and pressurization facilities, and a four-mile biogas pipeline connecting the dairies to the Aemetis Keyes ethanol plant.
The centralized biogas cleanup and onsite RNG fueling facilities at the Keyes plant are currently under construction for completion in Q4 2021, and the construction of 15 additional dairy biogas digesters are in progress for completion during 2022.
The biogas produced by the first two dairy digesters has received an approved pathway by the California Air Resources Board (CARB) utilizing negative 426 (-426) carbon intensity (CI) and is currently used to displace petroleum-based natural gas consumed at the Keyes ethanol production facility for process energy.
