Tesla might be most famous for producing electric cars, but the company also produces a range of batteries for both industrial and commercial use.
Now, the company has unveiled what it’s calling the ‘Megapack’ – an industrial battery that it claims could provide energy when an electricity grid is overloaded or stops receiving power.
The Megapack can store up to 3-megawatt-hours of energy at a time, and can even string together to store up to one-gigawatt hour of energy, which it claims would be sufficient to power a city like San Francisco for up to 6 hours.
As Tesla itself claims, “Megapack significantly reduces the complexity of large-scale battery storage and provides an easy installation and connection process. Each Megapack comes from the factory fully-assembled with up to 3 megawatt-hours (MWhs) of storage and 1.5 MW of inverter capacity, building on Powerpack’s engineering with an AC interface and 60% increase in energy density to achieve significant cost and time savings compared to other battery systems and traditional fossil fuel power plants.”
The Megapack itself is similar to the energy solution Tesla has piloted in South Australia until now, which was originally designed to replace gas “peaker” power plants. As TechCrunch reports, the Megapack itself comes fully assembled, and includes ‘battery modules, bi-directional inverters, a thermal management system, an AC main breaker and controls’, as well as the software necessary to run the system.
The system itself has reportedly saved the South Australian government some $40 million AUD in the course of just one year.
Set to be imminently installed and activated in California, the Megapack could well be used to store energy obtained from green sources – such as wind, hydroelectric, and solar power – to help reach the US state’s emissions targets.
Tesla has confirmed that Megapacks will now be installed in Monterrey Bay in California on a trial basis, and might roll out further in due course.
