Some electrical appliances continuously change the amount of electricity they draw from the grid so they can function correctly. Fridges, water heaters and air conditioners all subtly adjust the amount and the timing of their power consumption to keep temperature constant. RLtec’s dynamic demand technology harnesses this characteristic. It transforms these electrical appliances into intelligent devices that are able to draw more electricity when spare capacity is available, and less when the grid is overloaded. This provides a balancing service to the grid’s operators and enables them to match supply with demand. This form of balancing makes the grid more efficient. It is cheaper and produces less carbon than the gas or coal fired power stations that are traditionally used. Dynamic demand reads and responds automatically to signals from the grid. The appliance stays switched on and its overall performance remains the same, so users aren’t affected in any way.
