Largest WWTP biogas-to-RNG plant in the US operational
In the United States (US), Ameresco Inc, a renewable energy and energy efficiency company has disclosed that it achieved commercial operations in early 2019 at its 91st Ave renewable natural gas (RNG) plant located in Phoenix, Arizona. Now operational, this plant is the largest wastewater treatment biogas-to-RNG facility of its kind in the US and is capable of processing 3 250 standard cubic feet per minute (scfm) of raw digester gas produced at the wastewater treatment plant (WWTP).
In February 2017, Ameresco Inc., and the City of Phoenix hosted a ceremonial groundbreaking event at the 91st Ave Wastewater Treatment Plant (WWTP) in Phoenix to mark the start of this multi-million-dollar wastewater treatment biogas utilization project. The 91st Ave WWTP is owned by the sub-regional operating group (SROG) member cities: Phoenix, Glendale, Mesa, Scottsdale and Tempe and is operated by the City of Phoenix.
This innovative partnership allows us to turn waste into a resource by converting biogas, a byproduct of wastewater treatment, into renewable energy. This not only benefits our regional economy but also reduces greenhouse gas emissions. Phoenix has set ambitious sustainability and renewable energy goals, and this kind of public-private partnership will help us get there, said Phoenix Mayor Kate Gallego.
Now almost exactly two years later, Ameresco, the City of Phoenix and the SROG partners are celebrating the start-up of this monumental project.
This project exemplifies innovation in action and is a model for municipalities across the globe. We commend the City of Phoenix and the SROG member cities for both their commitment to sustainability and their initiative to derive economic benefit from a previously undervalued asset: biogas from wastewater. We’re thrilled to be a long-term partner to the City of Phoenix and proud to help the region reduce its reliance on fossil fuels, said Mike Bakas, Executive Vice President of Ameresco.
