Case Study

In early 2010, Metrus signed an ESA with BAE Systems, an aerospace and defense contractor with numerous facilities located throughout the United States. Under the ESA, BAE Systems was able to implement a comprehensive suite of energy efficiency measures at its Merrimack, New Hampshire facility. Metrus contracted with Siemens Industry to design, implement and maintain the Merrimack project. Project construction was completed in the fall of 2010 and BAE Systems now pays a quarterly output-based service charge that reflects the actual performance and realized savings of the project.

Scope of the Merrimack, N.H. Project

The 467,000 square-feet facility includes office space, environmental testing, manufacturing and assembly. Siemens installed the following measures as part of the project:

  • Equipment Replacement (i.e., air compressor, pump, transformer)
  • Building Automation
  • Lighting Retrofits
  • Operational Best Practices

Project Characteristics

  • Removes first-cost barrier to implementing efficiency improvements
  • Enables BAE to treat energy efficiency as a resource
  • Energy savings are variable and are calculated using well-proven industry protocols
  • During the term of the ESA, BAE has periodic termination and buyout options
  • The ESA is a structure that can fund efficiency improvements across a corporate portfolio of facilities (as highlighted by the closing of a second project with BAE in Greenlawn, NY)

Impact

  • $200,000 in annual utility savings
  • 1,000,000 of avoided kilowatt-hours of electricity
  • 30,000 therms of avoided natural gas use
  • Various non-energy savings (i.e., reduced maintenance expense)
  • 400 tons of CO2, the equivalent of removing nearly 70 passenger vehicles from road annually
