Home solar batteries used to power island grid at peak demand times

The Bruny Island community near Hobart, Tasmania agreed to participate in the CONSORT Bruny Island Battery Trial where 11 solar-powered home battery systems are providing backup renewable energy at peak electricity demand times. The island is a popular tourist spot and requires backup power usually for long weekends and other holiday periods. Originally the backup power was provided by diesel generators but now the island grid relies less on diesel. The battery owners can sell their extra power back to the grid using Reposit’s energy management software. For example, a retired couple have sold $180 worth of power back to the grid in their first four months on the trial. The plan is to eventually have 35 home batteries supporting the island grid.
