Energy Resiliency

Ameresco is pioneering energy security with flexible, scalable resiliency solutions that utilize a combination of power and thermal generation, energy storage and microgrid control systems. We design, deploy and manage power-generating assets supported with backup power sources, battery storage, and optimized use of the local utility grid. This microgrid system maximizes energy efficiency and cost savings and enhances the reliability of the electric supply for our military and civilian customers.

We specialize in energy assurance for mission-critical systems. On-site generation, such as solar photovoltaic (PV) or combined heat and power (CHP), creates a local generation source that can allow for sustained electrical supply during utility outages by incorporating black start and island mode capabilities. Energy storage provides responsive, reliable power to support islanding from the utility. We prioritize energy loads based on their criticality to site operations and use advanced control systems to shed non-critical loads and match available generation during a loss of utility.

Case Studies

The largest energy savings performance contract (ESPC) in U.S. history turned a coal-fired plant at the Department of Energy Savannah River Site into a biomass-fueled plant that generates power and heat through cogeneration.

Critical base systems can now operate without a tie to the external power grid, through a combination of on-site energy generation, battery storage systems and a microgrid control system. This new infrastructure also allows the base to disconnect from the grid during peak demand times, helping to lower energy costs.
