New Hub Injects 350 MMBtu/Day of Dairy-Based Gas
On February 9, 2026, Maas Energy Works and Pacific Gas and Electric Company (PG&E) announced the commissioning of a new renewable natural gas (RNG) facility at Couco Creek Dairy in Turlock, California. The site, which began full operations on December 31, 2025, is designed to inject approximately 350 MMBtu per day of pipeline-grade biomethane. The project is expected to reduce greenhouse gas emissions by an estimated 54,000 metric tons of CO₂e annually, equivalent to the energy-related emissions of 7,200 homes.
This facility introduces a hub-style model that enhances regional biomethane collection. It processes RNG from its onsite dairy digester while also serving as a central injection point for trucked-in RNG from the nearby Blue Sky Dairy. This "virtual pipeline" structure allows farms without direct pipeline access to participate in the renewable energy economy.
This hub represents the next phase of innovation in California’s dairy RNG sector — flexible infrastructure that helps family farms participate in the clean‑energy economy.

PG&E's RNG Network Reaches 8 Interconnections
The Couco Creek project is PG&E's eighth operational RNG interconnection, expanding a network that already sources biomethane from over 50 dairies, one landfill, and one food waste facility. The utility has firm plans to commission an additional seven RNG sites by the end of 2027. This expansion is a core component of PG&E's strategy to operate a net-zero energy system by 2040.
By the end of 2025, PG&E had already transported approximately 6.5 billion cubic feet (Bcf) of RNG through its pipelines, enough to supply more than 150,000 homes with energy for a year. The ongoing buildout of these interconnections strengthens PG&E's renewable gas supply and supports California's statewide goals for methane reduction from its significant agricultural sector.
