City of Sydney installs Tesla Powerpack battery in Transgrid network trial

The City of Sydney has installed its first grid-connected Tesla Powerpack – a 500kWh it has added to a 500kW rooftop solar system at a newly biult council depot.

The newly operational battery system was unveiled at the Alexandra Canal Depot last week, as part of a trial of behind the meter energy storage being conducted by NSW network operator Transgrid.

The Powerpack will be used by the City of Sydney to store excess power generated by the rooftop solar system, and minimise the grid consumption of the new Depot – which will accommodate 155 city workers and a fleet of 40 vehicles once officially opened at the end of the month.

On a broader level, TransGrid will use the battery as part of a trial effort to relieve stress on the grid during times of peak demand – and thereby reduce the need for investment in the transmission network.

“We know our customers want to see more innovative services that help reduce costs,” Transgrid CEO Paul Italiano said in comments on Thursday.

“This initiative with City of Sydney will afford the depot a significant amount of energy self-sufficiency while also sharing benefits with the wider community through the electricity network,”

“By partnering with a site where this service is needed, we can provide a benefit to support the City of Sydney’s renewable energy goals and reduce the costs of the council’s depot.”
