High-efficiency fluorescent lamps chosen by Corning Inc. for its Kennebunk, Maine factory combined with other improvements, have cut electricity use for lighting by roughly 40 percent, Maine Today reports.
The Corning plant, which employees 300 workers, represents one of the largest project aided by Efficiency Maine, which offers up to $50,000 a year in rebates for lighting and appliance upgrades.
Including other projects, the Corning plant will qualify for $59,000 in cash incentives. The investments are expected to pay for themselves in less than three years and cut total electric usage by 1.8 million kilowatt hours.
Corning ripped out 35-year-old lighting, replacing 1,630 fixtures. Light output has nearly doubled and the lights also run cooler, cutting air conditioning costs. In the warehouse, occupancy sensors turn on the lights, which used to be on 24/7.
