If you’re an LG&E customer, you probably got a phone call recently where they offered you a rebate for $20 to install something on your air conditioning unit. The small apparatus can also be installed on heating pumps and swimming pool heaters, and is designed to switch on and off the machine to save energy during peak periods.
According to LG&E:
In the energy business, “load” is the amount of energy a system is using at any given time. During the year, the amount of energy needed — or the “energy demand” — fluctuates depending on weather conditions or business hours of commercial or industrial customers. When demand for electricity is at its highest, that’s called a “peak” period.
Between June and September, when the temperatures outside are highest and the air conditioners are running their hardest. Cycling will occur on weekdays between the afternoon and evening, but never on weekends or holidays. Cycling should only occur 20 days per year and only when energy conservation is needed.
Air conditioning units or heat pumps in single family homes can receive five dollars per month, up to 20 per year. Electric water heaters or swimming pool pumps on single family homes receive two dollars per month, up to eight per year. Multi-family complexes are also eligible, two dollars per month with an eight dollar cap per year.
How It Works
The switch is connected to the low voltage wire that goes from your thermostat to your air conditioner’s compressor. The switch turns off the compressor just as if you had manually adjusted your thermostat to turn the air conditioner off for a few minutes. It’s that simple. Your switch is also a radio that receives the control signal from LG&E.
