South Australia’s big energy storage battery

Tesla to supply world’s biggest battery for SA, but what is it and how will it work? ABC By political reporter Nick Harmsen and Alle McMahon, 7 July 17 The “world’s biggest” lithium ion battery is to be built in South Australia by Tesla and French company Neoen.

It is to be close to the French renewable energy company’s wind farm near Jamestown and ready by the start of summer.

What is it?

An array of lithium ion batteries will be connected to the Hornsdale wind farm, which is currently under construction in SA. It will look like a field of boxes, each housing Tesla commercial-scale Powerpack batteries.

The array will be capable of an output of 100 megawatts (MW) of power at a time and the huge battery will be able to store 129 megawatt hours (MWh) of energy so, if used at full capacity, it would be able to provide its maximum output for more than an hour.

It will be a modular network, with each Powerpack about the size of a large fridge at 2.1 metres tall, 1.3m long and 0.8m wide. They weigh in at 1,200 kilograms each.

How will it stack up against the next biggest?

It will have just slightly more storage than the next biggest lithium battery, built by AES this year in southern California. But Tesla’s 100 MW output would be more than three times larger than the AES battery and five times larger than anything Tesla has built previously.

The largest lithium ion battery storage system that Tesla has built to date sits on a 0.6-hectare site at Mira Loma in southern California.

American electricity company Southern California Edison was also involved. It has a storage capacity of 20 MW, or 80 MWh, and is said to be capable of powering 15,000 homes.

The California array took three months to build. Tesla says the lithium ion batteries in the Jamestown array will have a life of about 15 years, depending on their usage and how aggressively they are recharged.

The company says the battery components are replaceable and the circuitry should last 20 to 30 years……..

How will it be used?

Neoen said the battery would primarily provide stability for the power grid, something traditionally the domain of coal, gas and hydro, rather than wind or solar………
