NASHVILLE, Tenn., Dec. 23, 2003 — Constellation Energy Group announced that its subsidiary, Constellation Energy Source, has named John Schaffer to the position of general manager of the new Nashville District Energy System (DES), the $48.2 million facility which replaced the Nashville Thermal Transfer plant on Dec. 15.
The City of Nashville retained Constellation Energy Source to design, build, operate and maintain the DES under a multi-year agreement.
“John Shaffer has done a remarkable job operating the existing DES plant and assisting with the construction of the new district energy system for Nashville. As such, he is the right person to manage the facility as we enter this next phase of the project,” said Greg Jarosinski, president of Constellation Energy Source. “John’s ably dealt with countless other challenges, from managing and increasing the reliability of the existing thermal plant to helping construct and manage our district energy plants in Pittsburgh and Las Vegas.”
“When construction ends, Nashville will have the most advanced district energy system in the country, and we’re certainly lucky to have someone with John’s talent and experience to run it,” said David Manning, Metro Nashville’s director of finance.
Initially, the new system will provide heating and cooling for approximately 40 downtown buildings, including the state capitol and other government buildings, The Coliseum, and a number of privately owned office buildings and hotels. The centralized system provides an energy-efficient, environmentally sound method of heating and cooling buildings, eliminating the need for each to maintain individual boilers or furnaces, hot water heaters, chillers or air conditioners. With the capacity to provide 20,800 tons of cooling and 260,000 lbs per hour of steam heat, the new system is projected to lower heating and cooling costs immediately for its customers.
Constellation Energy Source will manage, operate and maintain the DES for 15 years, with options for extensions, while Metro Nashville will retain ownership of the system.
Schaffer joined Constellation Energy Source in May 2000. Prior to that, he managed energy projects for Trigen Energy Baltimore/Trigen-Cinergy Solutions, LLC. He also worked with Locke Insulators and Domino Sugars in Baltimore as an operations engineer. He served in the U.S. Navy for four years, and is a licensed first-class stationary engineer. He also is a past board member of the Association of Energy Engineers.
Schaffer resides in the Nashville area with his wife and two children.
