South London householders could soon be helping the city manage peaks in electricity demand, with successful trials of a ‘virtual power station’ in the city having led to an expansion of the state-of-the-art battery storage scheme. The initial trial, which was led by UK Power Networks (UKPN), saw 45 households fitted with smart batteries allowing consumers to buy electricity at times of lowest demand when it is cheapest, and then store it for use when grid prices are more expensive, thereby helping to lower their electricity bills and reduce peak demand for the grid. UKPN found that during the trial household evening peak electricity demand fell by as much as 60 per cent, helping to cut carbon emissions for the average household by a fifth.
