Lots of opponents of battery storage for electricity that has been generated by wind, solar, and other renewables like to focus on how much those systems cost. Take the Hornsdale battery installed by Tesla last year in South Australia. It cost $66 million, and to hear some folks in Australia tell it, that money will place a huge burden on local utility customers forever. They conveniently forget to mention that the battery is a source of income to Neoen, the French company that owns it and the adjacent wind farm.
According to The Guardian, Neoen will recover more than one third of the $66 million cost of the Hornsdale battery in its first year of operation. A return on investment of three years is remarkable and something that should make other utility companies sit up and take notice. The payback time for most of their generating plants and infrastructure is usually measured in decades, not a few years.

SO this has stabilized the grid in SA and has been making lots of money.

If it keeps making that money in its 10 year life it will make 230million , and also 233% profit on cost, not really a tombstone.
There was so much crap about it being useless a year ago and turns out its profitable and very helpful to SA's grid

They earn income from the batteries when not required?

I wonder who pays for that?

DonDeeHippy wrote on Sep 30^th, 2018 at 5:25pm:



yes but it is only used when the power drops.

DonDeeHippy wrote on Sep 30^th, 2018 at 5:25pm:



Perhaps. You would need to provide figures to prove that.

Johnnie wrote on Sep 30^th, 2018 at 5:40pm:



That's what the batteries were for to cater for the intermittence of solar and wind plus other power dropouts.

"There are a range of methods and technologies to store energy. This can include batteries, flywheels, compressed air, thermal and pumped hydro. Learn more about energy storage.

Coupling energy storage with renewable energy provides stability services and emergency back-up power if a shortfall in energy is predicted. This helps overcome intermittent power generation (i.e. solar power is only generated when the sun shines), and can provide energy when it is needed."

If the SA Government says it, I guess it is true.

Since the interconnector failed Hazlewood has closed. Also the transmission line/wind farm failure. That puts extra stresses on the grid.

Johnnie wrote on Sep 30^th, 2018 at 5:59pm:



I am not selling them as a "fix"; as you pointed out there is too little backup to provide a solution for long term downtime.

"Industry analyst Giles Parkinson, who runs renewable advocacy website Renew Economy, said the figure was within expectations."

""The information that was released by Neoen a couple of days ago… makes it very clear the previous government's implementation and delivery of the battery was incredibly messy and overly expensive," Energy Minister Dan van Holst Pellekaan told ABC Radio Adelaide.

"It actually costs taxpayers' money. There's a cost of $4-5 million a year to have the battery in place.

"There are more costs than that involved.

    "The government of the day before the last election did not share all of the costs and all of the information."

However, Giles Parkinson said the battery was on track to "make revenues of about $25-26 million in its first year".

"We don't know what the profit margin of that is but we can probably estimate it's a fair profit margin," he said."

And my lights are on, are yours.

Its a mix and it has to be for now, I am probably getting a lot of my power from the windy mills on Yorke Peninsular at the moment, you also would be benefiting from this if you are on the main grid.

Johnnie wrote on Sep 30^th, 2018 at 6:39pm:



Why? CO2 pollution?

Today's wind energy Current about 20% capacity for SA.

https://anero.id/energy/wind-energy

out of 1786MW nameplate capacity.

Johnnie wrote on Sep 30^th, 2018 at 7:17pm:



Perhaps you can provide a reason why we should.

DonDeeHippy wrote on Oct 1^st, 2018 at 5:26am:



Perhaps that explains why most of the subsidies go to renewables.

lee wrote on Sep 30^th, 2018 at 9:14pm:

Yes, so that we don't kill off every single life form on this planet and earth ends up looking like mars well before it should. And it does make economic sense.
Do they have running water in WA yet?

Johnnie wrote on Oct 1^st, 2018 at 12:44pm:


You do know the difference between the gravity on Mars and on Earth? 

And of course with Temperatures of -81F there is no sign of runaway global warming.

If CO2 were the control knob of global warming shouldn't it be warmer on Mars?

Lee entirely missing a point yet again 

Johnnie wrote on Oct 1^st, 2018 at 1:21pm:



Please show where runaway global warming affected the earth in the past when CO2 levels were at about 7,000ppm, not the current 400 odd ppm.

Johnnie wrote on Oct 1^st, 2018 at 1:21pm:



So humans have stagnated. No thoughts on mitigation.

DonDeeHippy wrote on Oct 1^st, 2018 at 1:45pm:



So tell me how we are going to get runaway global warming and be like Mars.

Or perhaps when earth might get to the point of the atmosphere being mostly CO2?

DonDeeHippy wrote on Oct 1^st, 2018 at 2:04pm:



Then perhaps you can explain what his inferred point was.

If, of course it wasn't "don't kill off every single life form on this planet and earth ends up looking like mars well before it should"?

Johnnie wrote on Oct 1^st, 2018 at 4:36pm:



If that is the point perhaps you can refer us to a causal mechanism.

Johnnie wrote on Oct 1^st, 2018 at 4:36pm:



"Mars may have once possessed an atmosphere about as thick as Earth's, but then lost most of it to space due to solar wind and ultraviolet rays, a new study found."

https://www.space.com/36277-mars-thick-atmosphere-lost-in-space.html

Solar wind? Ultraviolet rays? Doesn't say anything about a future earth. And only "may have".

Johnnie wrote on Oct 1^st, 2018 at 4:36pm:



You do know oceans have been rising since the last Ice Age. Satellite snapshots of SLR are not really good. TOPIX, and the Jason series of satellites had an accuracy of more than 32mm. yet somehow they can infer an SLR of 3mm?

Johnnie wrote on Oct 1^st, 2018 at 4:36pm:


And yet China gets a free pass to contribute to CO2 levels until 2030 at least.

DonDeeHippy wrote on Sep 30^th, 2018 at 8:54am:

Without reading the 400 page document in your link can you tell me if these batteries are putting out any electricity or do they just sit there for 25yrs holding charge and then blow up.

lee wrote on Oct 1^st, 2018 at 8:21pm:

If you support renewables at all you should support them all the way in as many forms as they come to reduce intermittence. There should be wind and solar power all the way from Esperance to half way up the West coast and beyond to start with, although that would probably give you to much electricity and you wouldn't know what to do with it. Put it into batteries and truck it to SA, apparently there is a stability problem here.

why do u care what china does with CO2 when u don't believe CO2 is a danger Lee...
