The installation of earth energy units at a military base in Maryland will save more than $300,000 a annually when the units are commissioned later this year.
LEXINGTON PARK, Maryland, US, 2001-04-24 <SolarAccess.com> Alliant Energy Integrated Services – Cogenex will install $6 million of geothermal heat pumps at the Patuxent River Naval Air Station. In addition to the economic and environmental benefits of reduced energy usage, the upgrades will eliminate the discharge of water from an equipment cooling system into the Chesapeake Bay, which the state recently determined is environmentally detrimental to water quality. The installations will be done with Co-Energy Group LLC under the Department of Energy’s Geothermal Technology Specific Super Energy Savings Performance Contract. The two companies were chosen for the project based on their experience with geothermal systems and their approach to the installation’s needs. The project involves the installation of 125 geothermal heat pumps to replace existing conventional heating and cooling systems in buildings on the base. Earth energy technology (also called geothermal heat pumps or the new term, GeoExchange) transfer solar energy from the ground into a building for space heating and water heating. The units also cool buildings by discharging heat into the ground. Alliant Energy Integrated Services – Cogenex has installed 10,000 tons of geothermal systems in facilities across the U.S. since 1986. The Patuxent base houses the Naval Air Systems Command and the Naval Air Warfare Center Aircraft Division. The facility serves as the research, testing and evaluation, engineering and fleet support center for the Navy’s air platforms, and includes 935 buildings and employs 18,000 people. Other components of the Patuxent project include heating, ventilating and air conditioning improvements in buildings, installation of energy management systems, and upgrades to lighting systems. The work is expected to be completed this fall. “A growing number of government and institutional customers are turning to energy-saving geothermal systems to reduce their energy costs and be more environmentally responsible,” says Jon Bancks, president of Alliant Energy Integrated Services – Cogenex. “We are pleased that we were able to propose and implement a flexible approach that will generate long-term benefits for this important Naval facility.” The Cogenex division is one of five business platforms of Alliant Energy Integrated Services, the subsidiary of Alliant Energy based in Madison, Wisconsin. The division was formed three months ago from the integration of Energy Assets of Pennsylvania, EUA Cogenex of Massachusetts, and Alliant Energy Integrated Services – Energy Applications of Iowa.
