Central Plant Optimization Yields 25 Percent Efficiency Improvement
Savings of Over $500,000 Annually Expected in Energy, Repair and Unnecessary Services
NORRISTOWN, Pa. — When Pepco Energy Services (PES) wanted to find cost-effective ways to improve the operations of its Midtown Thermal Control Center (MTCC) in Atlantic City, New Jersey, it contacted Tustin Energy Solutions (TES), a commercial energy management company located in Norristown, Pennsylvania. TES made energy efficiency upgrades and utilized a non-proprietary automated plant optimization application. The result was a nearly 25 percent improvement in operating efficiencies and a savings of over $500,000 annually in energy, repair and unnecessary services.
According to Brad Pappal, TES general manager, the chiller plant was relying on many of the same control strategies that were in place when the plant was built over 15 years ago. It was operated and maintained with a series of independent components and controls that performed the function, but not necessarily efficiently. Based on Tustin Energy Services’ initial assessment, it was clear that the largest opportunity for cost effective energy reduction was in the chilled water production process.
