Case Study

Manufacturing Plant Achieved $50,000 in Annual Savings from Energy
Efficiency and Procurement Studies

Studies focusing on how energy is procured and used not only save energy but also improve productivity

HENRY (ARDEX), a manufacturer of premium adhesives, hired EN-POWER GROUP to develop and implement a comprehensive energy plan for their 126,000 sqft industrial facility in Bourbonnais, Illinois. This wideranging study incorporated energy benchmarking, energy auditing, and utility and tariff analysis to create an energy master plan for the facility.

To help ISO Plastics identify the most cost-effective energy conservation measures for its manufacturing facility, EN-POWER GROUP’s first step was to understand how the property used its energy. We began by enrolling the property in NYSERDA’s FlexTech Benchmarking program, which provided a rebate for energy benchmarking and energy auditing. Energy benchmarking is a process that compares a building’s current energy usage against its past usage as well as against buildings of similar size and type. The energy benchmarking results revealed the facility consumed higher levels of energy than comparable properties, and the on-site energy audit indicated several process equipment could be upgraded to reduce energy usage.

Using the knowledge gained from our energy benchmarking and auditing work, our engineers helped ISO Plastics enter into a more favorable energy contract. Next, our engineers met with ISO Plastics managers to help create an energy master plan with the goals of selecting cost-effective upgrades that maximized the use of available incentives. ISO Plastics installed a new 700-ton Injection Molding Machine that decreased peak demand, decreased operating costs, and increased manufacturing productivity. The energy upgrade was partly funded by ConEdison’s C&I Program.
