Leading the energy movement.

Ameresco helps organizations meet energy saving and energy management challenges with an integrated comprehensive approach to energy efficiency and renewable energy. Leveraging budget neutral solutions like energy savings performance contracts (ESPCs) and power purchase agreements (PPAs), we eliminate the financial barriers that traditionally hamper energy efficiency and renewable energy projects.

"Discovering new innovative energy sources is critically important...I am very proud of this private sector investor, as it works to reduce energy costs at Savannah River Site at no additional cost to the taxpayer and creates jobs which will spur economic development."

--Congressman Joe Wilson

Drawing from decades of experience, Ameresco develops tailored energy management projects for its customers in the commercial, industrial, local, state and federal government, K-12 education, higher education, healthcare and public housing sectors. By entering into an ESPC or PPA with Ameresco, customers can reduce energy costs and modernize their energy infrastructure. At the end of the contract, an Ameresco ESPC can provide additional savings for other capital expenditures. PPAs provide energy security and help to stabilize energy prices in both regulated and deregulated environments.

With up-front costs covered through an Ameresco ESPC, our energy efficiency solutions include lighting, window and HVAC replacements, installation of new boilers, chillers and on-site cogeneration equipment, and the latest energy management systems. We are also a leading developer of renewable energy projects, ranging from on-site biogas, wind, solar and geothermal power to distributed generation through biomass and landfill-gas-to-energy plants.

Ameresco also works between demand side customers and utility companies to manage energy price risk, procure or sell back renewable energy and automate invoice management. With Ameresco AXIS® invoice management, we can consolidate and analyze energy bills to identify opportunities for savings, set long-term price rates to mitigate market fluctuations and secure competitively priced traditional and renewable energy.

Ameresco performs custom, property-wide audits to uncover areas for cost savings from energy efficiency, renewable energy and energy management, including financing through an ESPC or PPA. We advise organizations on how they can use energy cost savings to finance energy efficiency and renewable energy projects, and outline a timetable for return on investment.
