A pilot project devised by Southern Tablelands Electricity in NSW to improve electricity supply in rural areas. It consists of batteries, an inverter and a computer program. It cuts in instantaneously and takes over supplying power whenever there's a blackout.
Blackouts are common in rural areas supplied by long feeder lines from urban power stations.
Secondly it cuts in and supplies power whenever a consumer uses more than a certain level of power i.e. it flattens out the demand peaks, then recharges over a period of time.
