Design, Build, Own, Operate, Maintain: Energy Efficiency Contracting

Figuring out how to operate and maintain renewable energy systems poses a challenge for commercial, industrial and municipal organizations constrained by budgets that offer no room for additional staff. Energy efficiency contracting services from Ameresco’s energy services specialists free businesses and municipalities from the ongoing expense of renewable energy systems while allowing them to reap the benefits of lower energy costs.

Operations and maintenance (O&M) expenses can vary greatly from one energy solution to another. While a solar array or geothermal system may need very little ongoing maintenance, wind turbines and landfill-gas-to-energy systems require skilled technicians to keep them operating efficiently. Simply finding the right personnel to operate and maintain advanced energy systems can be a challenge, as technologies are changing rapidly.

Ameresco can provide complete O&M solutions or integrated solutions with training for existing staff. As an independent company with no products to sell, our customers can choose best-in-class energy equipment solutions and gain control over the costs to operate and maintain them.

Connecticut Juvenile Training Facility Fuel Cell Plant


Faced with the need to replace a deteriorating facility, the state of Connecticut chose to include emissions-free, renewable energy as the power source for its new Juvenile Training Center. Ameresco designed, built and currently operates and maintains a free-standing, secure, 1.2 megawatt plant powered by fuel cells that provides electricity, heat and hot and cold water. At the time of its construction, it was the largest fuel-cell power plant in the world.
