Tesla to build 250MW “virtual power plant” in South Australia
I like this, 250MW/650MWh distributed over 50k homes.
This is awesome — love it!

This is right. Powerwalls provide a wide variety of services deep in distribution. It will take utilities a long time to figure out just how flexible and beneficial this can be. For example, voltage regulation is worth about 0.9c/kWh for all the power that flows through distribution (at least this was in the case of Nevada). For another, by using distributed Powerpacks for peak power, this lowers the capacity requirement for the transmission grid, and it also protects the substation transformers from heavy loads that prematurely age those assets. So there are many different value streams that distributed storage can provide that ultimately drive down the cost of transmitting and distributing power.I cannot overstate how satisfying this is to me.
A couple of things really didn't make sense fully originally. When Tesla first announced their battery products, there seemed to be more focus on the walls than the packs. That was unsatisfying, because packs looked like the product with bigger potential, and easier to scale. Of course the first few wins including Hornsdale were the packs.
Then came the news around flow batteries, which seemed to have a leg up on costs when compared to power packs. Not good.
But the key element here is, both power packs and large scale flow batteries require transmission and distribution investments, especially when you believe transportation is going electric. Scaling power walls like this to create virtual power plants is such an elegant and robust solution, that it just blows my mind.
PS: of course power packs can do so much more than flow batteries, like frequency and voltage regulation, synthetic inertia, etc., but from a pure $/kwh perspective, flow batteries can be cheaper.
Early evidence that the Hornsdale Power Reserve (aka Tesla Big Battery) is having a material impact in the energy market and prices:
Tesla big battery is already bringing Australia’s gas cartel to heel
FCAS service costs down 75% in the month of December (compared to the previous December).
There's an example of a recent situation where until recently, the gas generator / peaker plants that have provided the FCAS service have taken advantage of the situation to price the servive into the $10,000 - $14,000/MW range. The service btw is to have that capacity available and on standby - not to actually provide any actual electricity.
The Tesla big battery, and the attached wind farm, have begun bidding into that market (a specific outcome the South Australia government was looking for when it went looking for the big battery), and that recent situation saw the FCAS service stabilize at $270/MW.
My important takeaway from this is that this is a unit of evidence of how everybody that is a consumer of grid service benefits from batteries providing services that are historically provided by gas peaker plants. That price delta is a price that everybody else has to pay, and ultimately flows through to the bills that consumers and industry pay for electricity.
And it's why the next big thing out of South Australia - the 250MW / 650MWh virtual battery over 50k households is something that everybody* should view with excitement.
* all consumers anyway. The fossil fuel generators that have been gaming the system are probably not as excited about the new competitor.
More on the microgrid and Tesla batteries:Looks like Squaw Valley ski area (California) is going to install 8 MW (no word on Wh) batteries to overcome frequent power outages and stabilize the grid. Says they can run 6-8 hours on the batteries.

An interesting tidbit:Good round up of the recent FERC order here.

Allow all storage resources with a power capacity greater than or equal to 100 kilowatts to fully participate in the market.
More good news for Tesla battery storage. In Victoria Australia, Tesla will be installing another large battery -- 50 MWh/25 MW. Construction begins this month with project completion before next summer in Australia (toward the end of the year). Fluence (Siemens/AES JV) will also be installing a 30 MWh/30 MW battery.

Tesla also has another project in Victoria with Neoen to install a 34 MWh/20 MW battery scheduled for completion next year. Neoen starts work on next Tesla big battery project in Victoria
