Ameresco and City of Phoenix Announce 91 st Ave Wastewater Treatment Plant Biogas Project

Wastewater treatment plant biogas-to-renewable natural gas project is expected to be the largest of its kind in the United States once operational

FRAMINGHAM, MA and PHOENIX, AZ – August 15, 2016 – Ameresco, Inc. (NYSE:AMRC), a leading energy efficiency and renewable energy company, and the City of Phoenix today announced a multi-million dollar wastewater treatment biogas project at the 91st Ave Wastewater Treatment Plant (WWTP). Ameresco will design, build, own, operate and maintain (DBOOM) the innovative wastewater biogas-to-energy facility. The WWTP is owned by the Sub-Regional Operating Group (SROG) made up of Phoenix, Glendale, Mesa, Scottsdale, and Tempe. The WWTP is operated by the City of Phoenix.

The 91st Ave biogas project, which is expected to be operational in late 2017, will process the raw biogas generated in the anaerobic digesters into renewable natural gas (RNG) that will be sold to the vehicle market through the natural gas pipeline grid. The biogas is a mixture of different gasses (mostly methane and carbon dioxide) produced through the anaerobic decomposition of organic matter that is delivered to the WWTP. With a project size of 3,250 standard cubic feet per minute (SCFM) capacity, the project is expected to be largest of its kind in the nation.

“This cutting-edge partnership will enable Phoenix to turn wasted biogas from the plant’s digesters into green gas that can be sold for profit,” said Phoenix Mayor Greg Stanton. “This is a business opportunity that also improves air quality and reduces greenhouse gas emissions, which moves Phoenix closer to our goal of 15 percent renewable energy citywide.”

“The exceptional aspect of this project is the ability to capture a wasted resource and utilize it, thereby efficiently making use of this renewable energy asset,” said Michael T. Bakas, Senior Vice President, Ameresco. “Ameresco is honored to be partnering with the Sub-Regional Operating Group and we’re looking forward to making this project a reality for a community that recognizes the tremendous value and importance of environmental stewardship while improving infrastructure and reducing costs.”

The 91st Ave plant serves the cities of Phoenix, Glendale, Mesa, Scottsdale, and Tempe that make up the Sub-Regional Operating Group (SROG).

This project is expected to reduce carbon emissions by nearly 45,000 tons per year, the equivalent of taking over 70,000 cars off the road or planting over 87,000 acres of tress every year.
