LED PLUS CASE STUDIES
- Joe’s Grocery Store uses about 7,000 kWh in electricity each month.
- He enjoys a low fixed rate of 9.5 cents per kWh but he wants to reduce his energy costs without paying any money upfront.
- If he can reduce his annual electricity expense by about $2,000 that would be the equivalent of doing more than $60,000 in increased sales for the year.
- He is approached by a representative who explains the LED program to him.
- Joe’s 50 traditional fluorescent lights are replaced with high efficiency LED bulbs reducing his overall electricity consumption by 16%.
- Even paying a higher rate for the electricity for the next two years, the reduction in electricity consumption creates a small savings in the supply costs, and a large savings in the delivery costs.
- Also, the LED lighting is warrantied for two years, so he doesn’t have to change his bulbs twice a year like he was doing before – saving him money on maintenance.
- Over two years the LED program save him almost $5,000 (about 12%) overall while providing the grocery store with better, safer, brighter, more durable and more beautiful lighting.
- His customers and employees love the way the store is lit and he enjoys even more sales as a result.
- Over five years, Joe’s Grocery will save almost $15,000.
- He accomplished all this with no out of pocket costs at all and the representative has the satisfaction of knowing she helped a small business customer save money and improve his business.
