SINGAPORE – An energy storage facility to hold cool energy for use when there is a high demand for air-conditioning will be set up at the George Street Substation.
This energy will be used to cool the Marina Bay district, reducing the need for electricity during peak demand periods, said the statutory board Energy Market Authority (EMA) and utilities company SP Group on Monday (Aug 29).
Cool energy storage systems work by using electricity – usually when demand is at its lowest – to freeze a tank of water. Melting the stored ice can then provide cooling to buildings when demand for air-conditioning is high.
This reduces the amount of energy that is consumed from the grid for cooling purposes. The freed up electricity can be used to replace or substitute renewable energy like solar, when it is rainy or cloudy, for example.
