Tesla's Giant Battery In Australia Saved $40 Million During Its First Year, Report Says (electrek.co)

Last December, Tesla switched on the world's biggest lithium ion battery in South Australia to feed the country's shaky power grid for the first day of summer. Neoen, the owner of the giant battery system, released a new report for the first full year of operation and revealed that the energy storage system saved about $40 million over the last 12 months. Electrek reports: The energy storage capacity is managed by Neoen, which operates the adjacent wind farm. They contracted Aurecon to evaluate the impact of the project and they estimate that the "battery allows annual savings in the wholesale market approaching $40 million by increased competition and removal of 35 MW local FCAS constraint." It is particularly impressive when you consider that the massive Tesla Powerpack system cost only $66 million, according to another report from Neoen. Here are the key findings from the report:

- Has contributed to the removal of the requirement for a 35 MW local Frequency Control Ancillary Service (FCAS), saving nearly $40 million per year in typical annual costs
- Has reduced the South Australian regulation FCAS price by 75% while also providing these services for other regions
- Provides a premium contingency service with response time of less than 100 milliseconds
- Helps protect South Australia from being separated from the National Electricity Market
- Is key to the Australian Energy Market Operator's (AEMO) and ElectraNet's System Integrity Protection Scheme (SIPS) which protects the SA-VIC Heywood Interconnector from overload

      All I'm saying is that the battery is used to make the supply of fossil fueled electricity more stable by storing energy near where it is used. A function that would NORMALLY be accomplished by having a fossil fueled plant online to take up the slack. However, the logistics of transporting fuel and generating power is pretty difficult in the middle of the country and there is no water sources available, which makes electricity production even more logistically difficult (and expensive).

      The battery solution helps with logistics and costs, the grid can operate with acceptable margins with less cost and less spinning reserve. Fossil fuels are still where the energy comes from. This has not changed and isn't likely to change in the near future.

      It's obvious you don't know either the argument being made nor how a power grid has to work. And you OBVOUSLY don't understand what this battery solution is actually doing.

      The PROBLEM with Wind and Solar is that they are unreliable, you cannot schedule them to meet demand, you have to take the power and use it, store it or throw it away when it is generated from these sources. Sure, you could dump it into batteries and use it later, but this is extremely inefficient and expensive to do on an industrial scale. On an electric grid, every watt of electrical power must be generated the instant it is used or the grid becomes unstable, goes out of frequency spec, voltage specifications and fails. Currently there is reserve capacity provided by mechanically rotating machines, to keep things stable and in specifications, this reserve covers for instantaneous demand changes, transmission line failure induced transients and things like that. This is why they keep power plants online, spinning and ready to push power. Another plat may trip, a transmission line may isolate part of the grid and change the local load seen. This reserve capacity is used to keep the grid up because it WILL trip off line if things get out of whack too far.

      The Tesla battery is used to mimic this rotating storage, but it has a finite amount of power stored. The purpose is to allow time for the grid operator to bring additional electrical supplies online to make up for equipment failures or unexpected load changes. The battery is located in an area that suffers from being difficult to provide rotating power generation capacity. Giving "time" is the key. The more time the grid operator has, the more it can do to manage the flow of power and keep the grid within specs and providing power to it's customers.

      However, that battery provides backup power for a very short time, just long enough to keep the grid stable. Not enough time to make up for the day to day variations of wind and solar or provide a peak load for the grid on a hot cloudy still day.... In order to do that, your battery will need to be a couple of orders of magnitude bigger than what they have now. Remember, you are suggesting that we use batteries to hold the grid up for HOURS or DAYS when wind and solar are not producing enough power to meet demand. Right now, the battery being used is only capable of doing this for tens of min, and only while the grid is being reconfigured to fix what ever problem happened to trigger the event.

Renewables have to "fit" into the existing grid and its principles while they are the "minority" source of supply.

      Yes in that sense they are "unreliable" but they also have some benefits. For example, especially in the summer, peak power demand often coincides with peak solar production. So you don't need energy set aside to handle that peak, it's being produced and consumed then. Btw, the same applies for all other power plants to an extent - why do you think electricity is far cheaper at night in most places? Because large power plants can't be shut down that easily (i.e. shutting them down and re-starting them often does not make economic sense, and is technically difficult), so the low prices exist to shift some demand to the night to consume that electricity.

      Sure, you could dump it into batteries and use it later, but this is extremely inefficient and expensive to do on an industrial scale.

      I don't know about the price, but I'm pretty sure it's not inefficient.

      Currently there is reserve capacity provided by mechanically rotating machines, to keep things stable and in specifications, this reserve covers for instantaneous demand changes, transmission line failure induced transients and things like that.

      Reserve capacity is also provided by dams holding back rivers or pumped-up reservoirs. Which brings up the point that you could store wind and solar-generated energy using pumped hydro as well...this would probably be cheaper, but a less efficient than using batteries.

But by limiting the operating range (say, between 20%-80% of a full charge, which is what most EVs do), you can avoid the deep cycles and lengthen battery endurance considerably. That's how EVs are managing to go 10+ years on the same battery pack. Most of the automakers limit the battery's operating charge between 25%-75% or 20%-80%. Tesla is hush hush about their numbers, but it seems to be between 15%-85%. (This is why they could give owners additional range during hurricane evacuations - they simply sent out a temporary software patch allowing you to drain the battery below 15%.)

      The drawback of using only partial discharges is that you need significantly more battery capacity than you're actually using. Consequently, the cost of using batteries for load leveling is highly dependent on the variability in how much load leveling is needed day-to-day. If the same amount of power needs to be time-shifted every day, that's the ideal case. If the amount of power you need to time-shift varies by a lot (a little to none one day, close to max the next day), you end up having to pay for a huge battery but use only a tiny bit of its capacity most of its capacity most of the time

      This is different from something like pumped storage (pumping water uphill), where the bulk of the cost is in the pump and turbine, while reservoir capacity is nearly free.

    Certainly not energy consumers, they mostly pay fixed prices. Nor generators, they'll actually be worse off (they benefit from rapidly fluctuating spot prices). Electricity retailers would gain by smoothing out those fluctuations, but they pay for that gain in the form of hedging contracts - except now they're making some of those contracts with Neoen.

    So I have to conclude that, if that money exists, most of it should be going to Neoen. So... how is their actual P&L sheet looking?

    If they're not doing well financially out of this, then they're just blowing smoke, and this "$40 million" is about as meaningful as however many millions per week it was that the UK was supposed to save by leaving the EU.

    There are some plans in SA to store energy, by pumping sea water up to some old desert mines. Unclear whether they will go ahead.

    And the big missed opportunity for South Australia is to store nuclear waste in the middle of nowhere on the Eyre peninsular. Could power their economy for decades. And SA already has lots of nuclear underground -- natural uranium deposits. Anyway, the politics of those words "Nuclear" and "Waste" were too much.

    Incidentally, the geothermal plants that might be built there are actually nuclear powered. Not, like most geothermal, by being near the mantle, but rather being on top of a large, natural Uranium deposit.

    No one solution is the correct answer. Your 100% renewable pipe dream isn't either.

    Base load Natural Gas is currently the cheapest per megawatt that you can get, which is why even the cheap nuclear option is getting squeezed. The proven reserves of natural gas in the USA are literally HUGE and it's cost is projected to remain historically low for decades so building that NG plant is a low risk investment.

    The problem with renewables is their unpredictable nature. You cannot schedule generation capacity and expect a windmill to always meet demand. Sure, storage helps with that, but storage is limited and expensive (and don't forget inefficient). Most industrial sized storage solutions struggle to approach 70% efficiency. This means if you need a storage solution that can hold up your power grid over a calm cold night, you will need a LOT of batteries to keep the street lights and space heaters going while adding enough extra generation capacity on the windy days to charge everything up AND account for the 30% conversion loss. It's just not practical financially.

    Don't get me wrong, build the renewable options, use battery storage where it makes sense, just don't fool yourself into thinking we are poised to replace all the Fossil Fueled plants with this anytime in the foreseeable future. Natural gas is way too cheap and your solution way too expensive.
