A Domino’s Pizza franchise in the western Sydney suburb of Plumpton has laid claim to the world’s largest commercial Tesla Powerwall 2 battery storage system, after installing 10 of the US company’s 13.5kWh units – and not to store rooftop solar power, but to get around an existing network supply problem.

According to Chris Williams, whose company Natural Solar installed the battery system, the newly established Domino’s Plumpton hit a snag when it discovered its electricity load requirement outweighed the capability of the current network.

After much consultation and consideration, the decision was made to install the 135kWh Powerwall 2 array to avoid what would have been a very expensive grid upgrade. Indeed, the cost of the batteries will be half the the cost of the grid upgrade.
