The Maryland Board of Public Works today approved a $21 million contract with Pepco Energy Services, Inc. to implement an Energy Efficiency Program for Baltimore/Washington International Thurgood Marshall Airport and Martin State Airport. The energy performance contract will develop a number of specific energy conservation measures at BWI Marshall which will generate substantial energy and operational savings that are guaranteed by Pepco Energy. The majority of the cost of the work will be realized from energy and utility savings over the term of the contract.
“These conservation measures and improvements will result in significant energy savings for BWI Marshall Airport, a major facility and economic engine that is owned and operated by the State of Maryland,” said Governor Martin O’Malley. “This wide-ranging initiative demonstrates our commitment to energy efficiency and operational excellence.”
The contract’s energy conservation measures include a new 505 kW solar photovoltaic (PV) system on the roof of the BWI Marshall Daily Garage, comprehensive lighting improvements, and substantial energy infrastructure replacement projects at the Airport’s central utility plant and main terminal building. The projects will produce over $2 million in annual guaranteed energy savings.
“BWI Marshall Airport is committed to environmental stewardship and responsible resource management,” said Paul J. Wiedefeld, Executive Director of BWI Marshall Airport. “This energy performance contract provides excellent energy saving opportunities through critical infrastructure improvements and renewable technologies. The program is a thorough, innovative, and realistic approach to meeting efficiency and energy reduction goals.”
The first major project under the approved contract will be the installation of a solar PV system on the top of the BWI Marshall Airport Daily Garage. The Maryland Energy Administration awarded a $500,000 grant to pay for a portion of the implementation of this energy conservation measure. The BWI Marshall Daily Garage is a nine-story, 8,400 space parking garage. Pepco Energy will furnish and install the 505 kW PV system on a canopy system on the top level of the garage. The PV system will tie electrically to the Airport’s electrical distribution system. The green energy supplied by the system will be used to offset the electrical power supplied throughout the garage.
Another specific energy conservation measure is the installation of an escalator energy saving manager that will improve efficiency for the 64 escalators and moving sidewalks at BWI Marshall Airport. The devices adjust power usage to match passenger load. Electronic sensors automatically phase back the power supplied to escalator and moving sidewalk motors to optimize energy use without affecting escalator speed. Calculations indicate that this project would save BWI Marshall Airport about 200,000 kilowatt-hours per year from its escalator and moving walkways electrical use.
Additional energy conservation measures include the installation of improved lighting technologies and modern water conservation measures throughout the terminal and other Airport buildings.
Under the contract approved today by the Board of Public Works, the specific energy conservation measures will be installed at BWI Marshall Airport by December 2011. Funding for the contract is proved from the State Treasurer’s Office Master Energy Lease Loan, a Maryland Energy Administration Sunburst Block Grant from the U.S. Department of Energy, BGE rebates, and the State Agency Loan Program.
The energy performance contract approved today by the Board of Public Works reflects the goals of Maryland’s Smart, Green and Growing initiative. Introduced by Governor O’Malley in October 2008, Maryland’s Smart, Green and Growing initiative was created to strengthen the state’s leadership role in fostering smarter, more sustainable growth and inspire action among all Marylanders to achieve a more sustainable future. The Initiative brings together state agencies, local governments, businesses and citizens to create more livable communities, improve transportation options, reduce the state’s carbon footprint, support resource based industry, invest in green technologies, preserve valuable resource lands, and restore the health of the Chesapeake Bay.
