Maintenance
Elmendorf Air Force Base undertakes an Energy Savings Performance Contract with Ameresco
focusing on a heating system decentralization that produced over $5 million in savings in year one
alone.
Project Scope
Through an Energy Savings Performance Contract (ESPC), Ameresco decommissioned and demolished an
aging and inefficient central heating and power plant at Elmendorf Air Force Base in Alaska. As part of the
contract, Ameresco added new distributed boiler systems in 130 facilities ranging from residential, commercial,
industrial, and office spaces, encompassing approximately 1.5 million square feet. In addition, over 8 miles of
natural gas pipeline were constructed to these facilities.
Project Summary
Due to approximately 50 miles of deteriorating steam and condensate piping, Ameresco performed the
decentralization of the existing central power plant. Ameresco installed decentralized boiler plants (including
boilers, water treatment, required auxiliaries, and building structure) to serve each of the buildings that were
provided steam from the central power plant.
•	Energy Savings
Elmendorf AFB saved 1,095,376 mmBtu/year, equivalent to $3,711,053.
•	Investment
The initial investment for the project was $48,841,031 with an annual recurring cost for the Operations
and Maintenance of the boilers of $534,138.
•	Financial Return
The project produces an average annual savings of $5.58 M for the base. The project was structured to
pay for itself with no initial capital outlay within a 22 year term. During the first year, a Measurement and
Verification Report documented over $5 M of energy additional savings.
•	Other Benefits
An expensive operations and maintenance contract for the central heating and power plant was
eliminated. Also, electricity reliability was improved by upgrading the multiple points of electrical service.
The cost of this project also covered the demolition and decommissioning of the older central plant and
steam pits.
Monitoring & Verifying Energy Savings
A measurement and verification plan was established that measured the energy savings in year one through
direct utility metering. In each of the following years, boiler efficiencies are tested to ensure on-going savings.
Distinguishing Value
Elmendorf AFB and Ameresco worked this project in a true partnership. Project requirements and customer
needs were agreed upon and common goals were set from the start of the process. Elmendorf AFB has initiated
a truly positive and beneficial long-term relationship with Ameresco.
