Naval Facilities Engineering Command (NAVFAC) – US Navy

  • Mid-Atlantic & Southeastern United States

COMPLETED: June 2011
CLIENT: Atlantic Contingency Constructors, LLC and Eaton Corporation

Project Summary

This program was part of the 2009 American Recovery and Reinvestment Act (ARRA). The goal of the project was to modernize existing naval facilities throughout the southeast and mid-Atlantic region with grid-tied photovoltaic systems.

Blue Oak Energy Scope

BOE teamed with Eaton Corporation to evaluate over 150 sites. The investigation included roof area, structural adequacy, and existing electrical infrastructure for interconnection. BOE then continued to provide full electrical, civil and structural engineering from concept to issue-for-construction documents. Upon completion of design BOE continued construction administration services directly with ACC.

Project Goals

The US Energy Policy Act (EPAct) of 2005 requires the Secretary of Energy to ensure a minimum of 7.5% of the total electricity consumed by the Federal government comes from renewable sources by the year 2013. Photovoltaic systems are the ideal solution because onsite solar generation doubles the percentage of renewable energy recognized by the EPAct scoring system, thereby accelerating the Navy’s ability to meet the mandate.
