City of Phoenix and Ameresco Host Groundbreaking Event at the 91st Ave Wastewater Treatment Plant Biogas Project

Sub-Regional Operating Group (SROG) representatives including City
Leaders from Phoenix, Glendale, Mesa, Scottsdale, and Tempe participated
in today’s event

Inc. (NYSE:AMRC), a leading renewable
and energy
company, and the City of Phoenix today hosted a
ceremonial groundbreaking event for the start of a multi-million dollar
wastewater treatment biogas utilization project at the 91st
Ave Wastewater Treatment Plant (WWTP). Once operational, it is expected
to be the largest wastewater treatment biogas-to-renewable natural gas
facility of its kind in the United States. The attendees at the event
heard from a variety of speakers including City leaders and Ameresco

Phoenix Mayor Greg Stanton stated, “Making Phoenix more sustainable
isn’t just the right thing to do, it is also sparks innovation and
creates exciting new economic opportunities. By partnering with Ameresco
at our new processing plant, Phoenix is taking previously untapped raw
biogas generated by wastewater treatment and turning it into a renewable
energy source that can be sold. This cutting-edge partnership benefits
our regional economy and environment at the same time. Phoenix has set
ambitious sustainability and renewable energy goals, and this
partnership will help us get there.”

Michael T. Bakas, Senior Vice President, Ameresco said, “Ameresco is
honored to be partnering with the cities of Phoenix, Glendale, Mesa,
Tempe and Scottsdale, and we’re truly excited to break ground and get
underway. The exceptional aspect of this project is the ability to
capture a wasted resource and utilize it, thereby efficiently making use
of this valuable renewable energy asset. We’re looking forward to making
this project a reality later this year for a community that recognizes
the tremendous value and importance of environmental stewardship in
conjunction with fueling the local economic growth engine with this new
business while at the same time reducing its costs.”

Ameresco will design, build, own, operate and maintain (DBOOM)
the 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, and serves these cities. The WWTP is operated by
the City of Phoenix.

The 91st Ave biogas project, 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 nation’s natural gas pipeline grid. The
biogas is a mixture of various gasses (mostly methane and carbon
dioxide) produced through the anaerobic decomposition of organic matter
delivered to the WWTP. With a project size of 3,250 standard cubic feet
per minute (SCFM) capacity, the project is expected to be the largest of
its kind in the nation.

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.
