Tesla takes aim at gas plants with 3MWh “megapack” battery unit

Tesla has finally unveiled its long promised “megapack” battery, saying it would be a 1.5MW/3MWh unit designed to target the booming utility-scale energy storage market – and marketed as a sustainable alternative to gas “peaking” power plants.

The US electric vehicle and battery manufacturer said on Tuesday that the new lithium-ion product, inspired by the great success of South Australia’s Hornsdale Power Reserve, would allow the installation of gigawatt-scale “power plants” four times faster than a fossil fuel plant.

Tesla chair Robyn Denholm, an Australia, made a rare public appearance on Tuesday, at the Clean Energy Summit, and said the new “megapack” would allow the company to take grid scale storage to a “massive scale”, and would take higher cost and emissions intensive plants – such as gas peakers – off line.

he Neoen-owned facility – situated next to the Hornsdale Wind Farm – has been a huge success, both as a source of revenue, and for its critical role in maintaining grid security, and preventing blackouts, as highlighted by its response to the dramatic inter-connector failure in August.

Two years later, far from being the “Kardashian” of the energy world that Matt Canavan predicted(and whatever that might mean!), it has set the standard for what the future grid might look like. (Denholm noted it had slashed FCAS costs by 57 per cent and saved the state government $40 million in grid security costs).
