100 MW/129 MWh batterijpark, kostprijs $66 milj, bracht reeds $17 miljoen op tijdens eerste 6 maanden, en is goed op weg ruim meer dan 20 miljoen/jaar op te brengen... op pakweg goede 3 jaar zou die al terugbetaald zijn.

The giant battery cost ~$66 million and it reportedly already made up to $17 million during the first ~6 months of operation.

Tesla’s 100MW/129MWh Powerpack project in South Australia provide the same grid services as peaker plants, but cheaper, quicker, and with zero-emissions, through its battery system.

It is so efficient that it reportedly should have made around $1 million in just a few days in January, but Tesla later complained that they are not being paid correctly because the system doesn’t account for how fast Tesla’s Powerpacks start discharging their power into the grid.

The system is basically a victim of its own efficiency, which the Australian Energy Market Operator confirmed is much more rapid, accurate and valuable than a conventional steam turbine in a report published earlier this year.

Overall, it is estimated that Tesla’s giant battery in Australia reduced the grid service cost by 90%.

The energy storage capacity is managed by Neoen, which operates the adjacent wind farm.

Last week, Neoen filed for a IPO on the Paris financial market and in its registration documents, the company revealed new financial details about the big battery.

The French energy company revealed that the entire system cost 56 million euros (~$66 million USD).

While it’s interesting to finally have the full cost of the giant Powerpack system, it’s even more interesting to get an idea of the return on investment as Neoen confirmed the revenue generated by the system so far.

The French company disclosed that they made 8,1 million euros ($9.5 million USD) for the grid services and energy sales and 6,7 million euros ($7.9 million USD) for storing and selling electricity from the Hornsdale wind farm.

It’s unclear how Neoen is attributing the value of the stored electricity from its wind farm since it is accounting the two assets as a whole in terms of revenue, but it would mean the battery system generated between ~$10 million and $17 million during roughly its first 6 months of operation and it is on pace for over $20 million in revenue during its first year.

The cost of operation are not made clear in the filings, but we would assume that they are fairly low, which would make the return on investment extraordinary quick for the massive project.

Tesla recently released new images of the completed system and a timelapse of its construction:

Neoen is trying to raise 450 million euros with its IPO in order to accelerate its renewable energy deployment. The company currently has a capacity of 2 GW and it wants to be at 5 GW by the end of 2021.

Here’s Neoen’s full ‘document de base’ for its IPO (it’s in French):

Men rekent dat zulke systemen de netwerkkosten met 90% kunnen verminderen.

Overal worden nu zulke opslag-batterijparken aangelegd, deze is dus al 6 maand aktief bij de *Hornsdale Windfarm, andere volgen...

Neoen alleen wil tot 5 GWh beheren tegen einde 2021.

Hornsdale Power Reserve

Tesla, Inc. won the contract and built the Hornsdale Power Reserve adjacent to the Hornsdale wind farm, for a cost to Tesla of about US$50 million.[8][9] It is promoted as the largest lithium-ion battery in the world.[10] Samsung 21700-size cells are used.[11]

It is owned[12] and operated by Neoen, with the government having the right to call on the stored power under certain circumstances.[13] It provides a total of 129 megawatt-hours (460 GJ) of storage capable of discharge at 100 megawatts (130,000 hp) into the power grid, which is contractually divided into two parts.[14]

70 MW running for 10 minutes (11.7 MWh) is contracted to the government to provide stability to the grid (grid services)[15] and prevent load-shedding blackouts[16][17] while other generators are started in the event of sudden drops in wind or other network issues. This service has reduced the cost of grid services to the Australian Energy Market Operator by 90%.[18]

30 MW for 3 hours (90 MWh) is used by Neoen for load management to store energy when prices are low and sell it when demand is high.[19]

The battery construction was completed and testing began on 25 November 2017. It was connected to the grid on 1 December 2017.[20] This easily beat Elon Musk's wager of "100 days from contract signature",[9][21][22] which started when a grid connection agreement was signed with ElectraNet on 29 September 2017.[8] Tesla had already begun construction, and some units were already operational by the time the contract was signed.[16]

On 14 December 2017, at 1:58:59 am, the HPR reacted when unit A3 at Loy Yang Power Station tripped. As its generators spun down over the next 30 seconds, the loss of its 560 MW of base power caused a dip in the system frequency. By 1:59:19, the frequency had fallen to 49.8 Hz, and triggered HPR's response, injecting 7.3 MW into the grid and effectively helping to stabilise the system before the Gladstone Power Station was able to respond at 1:59:27. This synchronverter reaction is a built-in feature, but had not previously been effectively demonstrated[15]

During two days in January 2018 when the wholesale spot price for electricity in South Australia rose due to hot weather, the battery made its owners an estimated A$1,000,000 (US$800,000) as they sold power from the battery to the grid for a price of around A$14,000/MWh.[23] Based on the first six months of operation, the reserve is estimated to earn about A$18 million per year.[24] (This is an third-party estimate, based on spot energy prices; it is possible that the HPR has contracted to provide power at a lower price, in exchange for a more certain income stream.)

After six months of operation, the Hornsdale Power Reserve was responsible for 55% of frequency control and ancillary services in South Australia.[18]
