Brookshire Brothers expects to reduce its annual operating costs more than $235,000 after installing GE energy-efficient lighting at its retail supermarkets in Texas and Louisiana, according to the companies.
The company launched a facility-wide lighting update at its 72 stores including in-store, parking lot, exterior signage and refrigerated case fixtures. Using several new linear fluorescent lighting (LFL) and LED technologies from GE Lighting, Brookshire Brothers expects to cut its annual electricity use by 2.4 million kWhs, and eliminate more than 3.8 million pounds per year of CO2 emissions, the companies say.Brookshire Brothers has completed re-lamping of linear fluorescent lighting (LFL) fixtures at 69 locations, replacing its older 32-watt bulbs with GE’s more energy-efficient 28-watt T8 in some 450 four-lamp fixtures per 30,000-square-foot supermarket.
These efforts also include replacing existing ballasts with GE’s high-efficiency UltraMax electronic ballast as needed. GE says each UltraMax ballast installed will create additional energy savings of about 8 watts per fixture.
According to the companies, Brookshire Brothers will save an average $3,200 per store per year in electricity expense after switching to GE’s 28-watt bulbs. This saves the company more than $220,000 annually based on a $0.09 kWh electricity rate and 12 hours use per day.
Additionally, five supermarket parking lots including company headquarters have been retrofit with GE Evolve LED area lights. These 210-watt lights replaced 400-watt high-intensity discharge (HID) fixtures in two lots; the other three lots used 270-watt area lights to replace 1,000-watt HIDs. Brookshire Brothers says this retrofit will save more than $14,000 annually in electricity costs.
Several outdoor walkways also now use GE Tetra LED lighting systems, which GE says cut energy use by 80 percent compared to traditional fluorescent and neon options.
The supermarket chain installed GE’s Immersion RV40 LED lighting (pictured) in refrigerated display cases in four Brookshire Brothers locations, which house 100 frozen food doors on average. GE says these lights eliminate glare, reduce energy use by 60 percent and are rated for 50,000-hours life, which is four times longer than the fluorescent lights they replaced.
Additionally, wine displays in two stores have been lit with GE’s energy smart LED replacement lamps. GE’s 10-watt PAR30 LED floodlights (500 lumens) replaced 45 75-watt halogen lamps (940 lumens) in each store. This will save Brookshire Brothers $3,200 in combined annual energy and maintenance savings; GE says the wine display lighting will pay for itself in 13 months.
In late November, Sheetz retail gasoline/convenience stores installed LED lighting by Cree at some 130 locations, which is delivering a 45 percent reduction in energy costs for interior lighting and a 50-55 percent reduction in exterior lighting compared to the lighting it replaced.
