Supermarket Chain South Central

One of the nation’s largest privately-owned grocery chains wanted to do something about their energy consumption and improve their profits without compromising customer satisfaction.  In order to achieve these goals, they turned to Amtech Lighting Services, a company honored as an ally in the Green Lights and Energy Star Buildings programs. 

Accepting this challenge, Amtech designed a comprehensive re-lamp, retrofit, and maintenance program.  The first phase of the program included the replacement of existing 400-watt metal halide lamps with 350-watt pulse start lamps, and a complete T8 lamp and electronic ballast retrofit for all the fluorescent lighting throughout the 260 store chain.  This introduction of pulse start technology has yielded savings of 83 watts per fixture as well as an increase in lighting levels by 27%.  Another major advantage to using this pulse-start technology is the 3-minute hot restrike compared to the 20-minute restrikes of traditional metal halide lamps.  This upgrade is only the genesis of the comprehensive 4-year plan that is currently in motion, the outcome of which will be more than $3 million per year in savings over the four years.  Additionally, the new technology will eliminate the release of millions of pounds of carbon dioxide into the environment.  Lastly, the customer will be experiencing altogether a savings in kilowatt-hours of 76 million annually.

“We are very pleased with the energy savings and also impressed with the payback of the program,” noted the Energy Manager.  He continued in mentioning that “each store has achieved a reduction in energy costs and a better shopping environment for customers.”  There have been dual, value-added benefits to Amtech’s project; that is, the energy-savings and fiscal reward, as well as a better environment for their shoppers.
