Tesla copped plenty of flack when it delivered on a promise to build the world’s largest lithium-ion battery in Hornsdale, South Australia. There’s any number of arguments to bag the concept, but the fact remains they did it and close to $40 million has been saved during the first year of operation.
But now Telsa has come up with the Megapack. It’s designed for large scale projects like Hornsdale, but with the intent of reducing the complexity of large-scale battery storage.
Each Megapack arrives fully-assembled from the factory. It has up to 3 megawatt hours (MWhs) of storage and 1.5 MW of inverter capacity. The Powerpack technology used in Hornsdale has now been enhanced via engineering with an AC interface and 60% increase in energy density.
Via the Megapack Tesla now claim it can deploy an emissions-free 250 MW, 1 GWh power plant in less than three months, one that covers three-acres. It’s also capable of being DC-connected to solar systems.
This is a constantly evolving area of technology, one that should be carefully considered before making the all too easy “Oh Elon, he’s mad” style observations.
