LED Site Lighting Case Study Carroll EMC Carrollton, Georgia
●Project Description
■Carroll EMC, headquartered in Carrollton, Georgia, serves 39,000 members across a seven county region. The company continually evaluates new technologies and supports its customers in energy efficiency initiatives. As part of this commitment to serving its customers, Carroll EMC partnered with Cooper Lighting to retrofit its corporate parking lot with LED lighting. The company incorporated several types of Cooper Lighting LED outdoor fixtures in the project design so the utility and its customers could gain a better understanding of, and become familiar with, a variety of LED fixtures.
■The project included retrofitting the existing 100W-400W HPS and 1000W MH fixtures with Cooper Lighting Streetworks Talon Medium LED luminaires (146W), OVF LED Roadway Large Cobraheads (146W), Traditionaire LED luminaires (58W) and Generation Series (58W) LED luminaires. As a result, the utility's electrical load was reduced by 72 percent or 6.6 kW for that area, resulting in a projected annual energy savings of $2,600(28,900 kWh)with a 3.6 year payback.
■"We were very excited to take a step into the world of LED lighting and enjoyed working with Cooper Lighting and its agent, "said Jerome Johnston, Carroll EMC's Vice President of Engineering and Operations. "We are extremely pleased with the improved light levels and overall appearance of the LED lighting, as well as the significant energy savings. As we encourage our members to embrace energy-saving technologies, we are excited that we can share with them our own LED lighting experience."
