The Powerpacks Contain Smaller Battery Pods

Tesla co-founder, chief executive and product architect Elon Musk apparently isn’t one to turn down a Twitter problem. Another company official said publicly in March that Tesla could remedy the blackout-plagued Australian state of South Australia’s power woes by putting in a massive battery storage system in under a hundred days. In response, Australian billionaire Mike Cannon-Brookes tweeted back, asking Musk how critical he was in regards to the offer, and whether or not he could guarantee that it may very well be completed in that time.

Musk’s reply was to promise that Tesla would get the system installed and working a hundred days from the signing of a contract, or else provide it without cost. «Is that severe enough for you?» he asked.

Positive enough, Musk didn’t have to select up the price of the mission, 西武 ライオンズ FA reportedly $50 million in U.S. dollars. Final week, South Australian Premier Jay Weatherill announced that the storage system had been totally installed, more than a month forward of the deadline, and would be energized within days for testing. As Musk explained in a video in October, the system installed in South Australia is three times greater than the earlier report-holder, a 30 MW battery system unveiled again in February at a utility substation in Escondido, California.

The appearance of giant-scale battery storage has the potential to solve a problem that hinders the advance of renewable energy sources similar to wind and photo voltaic, as a result of it will help to easy out dips in provide that happen when the wind dies down or the weather turns cloudy. (Here is a 2010 report from the National Renewable Vitality Laboratory on the significance of storage capability.) And having battery storage additionally may assist to stop blackouts such as the massive outage that hit South Australia in September 2016, after tornadoes broken power traces and precipitated the grid to malfunction. But the corporate did confirm some data concerning the battery mission.

Whereas everyone is calling it a giant battery, the 100 MW Tesla storage system — which might provide 129 megawatt-hours of electricity, sufficient electricity to briefly power 30,000 houses — actually is not a single unit.1 meters) tall and weigh three,575 pounds (1,622 kilograms) every. The Powerpacks include smaller battery pods, based mostly upon the identical expertise used in Tesla’s Model S electric car, as well as a thermal control system and tons of of sensors that monitor efficiency, in accordance with Tesla’s web site. There’s additionally an integrated inverter, to transform the direct present saved in the batteries to the alternating current that goes into the utility system. Each Powerpack can supply 210 kilowatt hours of electricity.

Tesla’s Powerpack system is designed to be versatile and scalable, in order that the identical models can be utilized to offer power for a couple of small companies or, in bigger configurations, serve as a backup system for a public utility, in keeping with the website.

As for the newly installed Tesla system in South Australia, an important innovation is the sheer scale of the challenge, in accordance with Tony Wooden, a former Clinton Administration energy official who now is director of the power program at the Grattan Institute, an Australian public coverage think-tank.

«We are going to learn loads over the coming Australian summer as to what role battery know-how can play within the accelerating transition from thermal energy plants to wind and photo voltaic,» Wood writes in an email.

The lengthy-time period practical potential for battery storage — whether or not it can help drive a transition to renewable energy, or whether it principally can be useful for blackout prevention — nonetheless stays to be explored. «I don’t think anybody really knows as but,» Wood says who notes that battery storage presently stays dearer than pumped hydro, which uses reservoirs of water as a storage medium. «Economics of scale and different price-reducing parts are still unclear. That’s one reason why this undertaking and others prefer it are so vital and thrilling.»

Jason Burwen, policy and advocacy director of the Vitality Storage Association, says:

«Tesla’s project demonstrates three key things. First, battery storage will be deployed on the grid at large scales in very quick timeframes that no other useful resource can match — and this ‘just-in-time’ capability provides enormous flexibility in grid planning. While Tesla did this in document time in Australia, it comes on the heels of comparable battery tasks in California that took only four to six months from contract approval to in service — so this isn’t just a one-off. Second, battery storage is right here and ready for grid service at present. This is not some ‘technology of the longer term,’ but rather a present grid answer whose prices are declining rapidly and whose performance is rising steadily. Third, battery storage is one thing that everybody gets excited by, no matter political affiliation. There are few things that unite people in power, however it seems clear to me that storage does.»

Now That is Attention-grabbing Tesla might not hold the battery record for too long. Australia’s Lyon Group is developing an enormous photo voltaic-vitality storage facility in South Australia, which could have a capability of 100 MW/400 MWh, in keeping with the company’s web site.
