By investing in batteries on the grid, United Energy can deploy less battery capacity to deliver the network benefit required, compared to relying on many household batteries to provide the same benefit.

The pole-top batteries aim to solve two common network problems: managing the export from rooftop solar generation and meet the increasing demand on scorching days.

My first thought would be whether having the batteries suspended on the poles is somehow higher risk, though-- wouldn't it be safer from the elements (big storms or other issues that sometimes bring down poles) on the ground somewhere?
