@Dborn I'm sorry mate, but what a lot of tosh, very easy to reveal your political colours when you cannot see the menace in the article. The SA government is making an investment in its very own energy future. If grid prices spike to $14,000/MWh like they did recently then guess what.....the govt will pocket $1,400,000 million to supply this power minus the $6,000 it cost to procure it, by discharging the battery once, just once, I'm guessing the warranty in this puppy will be a minimum of ten years, so that is around 40,000 opportunties (under warranty). The whole purpose of this battery is 1. to stop enormous price spikes and manipulation occurring and 2. to stabilise the power from the Hornsdale wind farm.
Everything gets presented in a subsidy when in reality it simply isn't the case. The SA government has lost all faith in the private sector gas generators which sat idle in the blackout events and have moved to secure their own assets, the battery being part of it. Australia's future is solar, stacks of it. Look at China for instance, this installed 10.52 GW of capacity...IN JULY, just JULY 2017.
China Continues Massive Solar Installations With 10.52 GW In July, Already Exceeds 2020 Target
Our future is not in nuclear, there is no future for Nuclear, it is just sooo monstrously expensive to build new Nuclear. As Melocomm has pointed out, Hinkley Point C is going to be an unrivalled disaster. To 'subsidise' this plant the British govt has agreed that for 35 years (yes 35) it will guarantee a payment of 92.50 GBP per MWh, which increases with inflation. The plant is not slated to start production until 2025 and as recently as July EDF added another 1.5 Bn GBP to the cost, lets see how that creeps up in teh next few years, it is already at 19.6 Bn GBP and it only just made it out of final investment decision at EDF. Interestingly the most recent offshore wind auctions reached a guaranteed price of 57.5 GBP per MWh, guaranteed for 15 years. These price guarantees only covver the shortfall between the wholesale price, ie. if the wholesale price on the day is 40 GBP per MWh then the govt owes 17.5 GBP for every MWh of power bought from the wind farm, or 52.5 GBP per MWh bought from Hinkley C. If the wholesale price is above the guaranteed price, the wind farm pays back the difference. I doubt Hinkley C will ever be paying anything back.
Offshore wind cheaper than new nuclear
Hinkley Point builder raises cost estimate
Those articles are worth a read, all this in the face of wind power turning to giant turbines, and now starting to see some cost efficiency delivered in manufacturing, installation and operation. The recent auctions in Australia are also delivering some impressive strike prices.
The closure of our fossil fuel plants should be orderly and planned. These plants are aging and to build new coal is simply more expensive than either solar or wind, even including battery. To maintain them will cost more than what it is worth to replace their capacity. Liddell and Hazelwood rarely ran at more than 50% capacity, it just doesn't represent the operational legacy whenever 2000 MW is used for Liddell for instance, yes that is it's nameplate capacity, but that is all. We actually need to look at how many MWh is needed from the plants, and replace accordingly. We need to stop being stuck in an old fashioned way of thinking. We already have huge storage an generation capacity in both Snowy, and Tassie. We simply need to stop using these assets as 'production' assets and we would no need huge amounts of storage to be built. We need to shed all of the load that is not required to be a night ie. hot water. Energy efficiency program and demand response would create a smarter, more resilient grid. This is all going to happen whether the current govt likes it or not. My solar system I just installed has LCOE of 4 c/kWh, vs grid purchases at 35c/kWh. Over the next few years people will start to wake up and see the simple mathematics behind local generation of renewable energy. Our very own cars are enabling this transition to occur, ensuring economies of scale were and continue to be achieved in the manufacture of batteries.
One final point, it is interesting that Peta talked about the 'reliance' on the interconnector, the failure of the interconnector was one of the reasons the state went black, the other primary reason being the failure of the gas plants. Doesn't matter if Hazelwood is on or not if someone pulls the f'ing plug out.
