What is a grid-connected battery system?The use of energy stored in a grid-connected battery system to meet on-site energy demands, reducing the reliance on the external grid. The gradual loss of stored energy in a battery over time due to internal chemical reactions, even when it is not connected to a load or in use.
Why do we need a grid-scale energy-storage system?Under some conditions, excess renewable energy is produced and, without storage, is curtailed 2, 3; under others, demand is greater than generation from renewables. Grid-scale energy-storage (GSES) systems are therefore needed to store excess renewable energy to be released on demand, when power generation is insufficient 4.
