CUSTOMER: Mark Martin Dealership


The Entergy Arkansas Large Commercial & Industrial Program helps customers like dealership owner and NASCAR driver Mark Martin operate facilities more efficiently by increasing energy efficiency. In an effort to achieve significant, long-term electricity savings, Martin enlisted the help of the program team and a local lighting contractor to explore savings opportunities at his dealership.


While projects using LED bulbs are less common, Martin was intrigued by the notion that while the capabilities of LED products are increasing, the prices are decreasing.  So, rather than implementing a traditional lighting retrofit using CFL or fluorescent light bulbs, Martin and the program team decided to replace all 1000 Watt metal halide fixtures in the exterior parking lot with 284 Watt LED fixtures. The project would not have been possible without a demonstrated annual savings and program incentive that would yield a short payback period. 


As shown above, the lighting upgrade resulted in significantly increased energy efficiency and an ROI that worked with the Martin's budget. Most notably, the savings achieved are equivalent to eliminating the annual greenhouse gas emissions from 42 passenger vehicles, according to the Environmental Protection Agency.
