The world's largest lithium-ion battery has begun to generate electricity for South Australia's electricity network.

The 100 megawatt battery, built by Tesla, was officially commissioned on Friday. In fact, the energy began to flow into the network from Thursday, due to the increased demand: due to the abnormal heat, a lot of electricity is required for the continuous operation of air conditioners.

In recent years, South Australia has experienced serious energy problems.

The head of Tesla Ilon Mask once promised to build a battery for 100 days - this is a promise he fulfilled.

The giant battery is designed to prevent incidents like last year, when the whole staff was left without electricity.

According to Mask, his battery is three times more powerful than any analogues created so far.

The battery in South Australia is just one of several similar projects in which Tesla.

Smaller energy stores designed to ensure uninterrupted and stable power supply operate in southern California, New Zealand, the United Kingdom, Hawaii and a number of Pacific islands. Some luxury hotels located on islands and in hard-to-reach places also use small energy banks.

The company also reported the shipment of a large batch of batteries to Puerto Rico, where the power system was completely destroyed by hurricane Maria.
