What They Do

Ameresco has transitioned from a focus on energy efficiency and conservation to a comprehensive energy infrastructure solutions provider. Their offerings include upgrades to aging infrastructure, smart energy efficiency implementations, and the development, construction, and operation of distributed energy resources such as renewable energy plants. This product-neutral and supplier-independent approach allows them to effectively address both energy supply and demand (source: ameresco.com).

Projects & Track Record

Ameresco has a notable track record of energy-saving projects across various sectors, including government, healthcare, education, and commercial clients.

They currently manage over 150 megawatts of solar facilities, showcasing their capabilities in renewable energy (source: ir.ameresco.com). Ongoing major projects include the £1 billion Bristol City Leap Partnership in the UK, a city-wide decarbonization initiative that is projected to create over 1,000 local jobs and generate £61 million in social value within its first five years (source: ir.ameresco.com). Their geographic presence spans the US, Canada, the UK, and broader Europe, supported by over 50 offices (source: ameresco.com).
