The world’s largest lithium-ion battery, Hornsdale Power Reserve, built by Tesla in South Australia, will be expanded another 50 percent next year. We remind our readers that this power plant was built by Tesla in 2017 in order to solve the problems of existing power grids at the disposal of Neoen. Elon Musk, the founder and CEO of Tesla, promised to complete the construction of the Hornsdale Power Reserve battery in 100 days and he kept his promise completely, thanks to which the battery went into operation in November 2017, three months after the start of the first work.
The nominal capacity of the Hornsdale Power Reserve battery is currently 129 MW * h and it is capable of delivering a peak power of 100 MW, making it the world’s largest lithium-ion battery. And this title, it seems, will last for a long time, thanks to the planned expansion and modernization.
Tesla and Neoen, with support from the South Australian government, plan to add a 64.5 MWh capacity and 50 MW additional output to the Hornsdale Power Reserve battery. Modernization of the battery will also include the introduction of Tesla Virtual Machine Mode technology, which will compensate for the inertia of the energy system and ensure stability of the system at times of strong fluctuations in peak load.
The total power system of South Australia requires an inertial index of the order of 6,000 megawatt-seconds. And, according to information from Neoen, the upgraded Hornsdale Power Reserve battery will be able to provide exactly half the required energy. Currently, work is already underway related to the preparation of the modernization of the battery, and the modernized battery should go into operation in mid-2020.
