Tailem Bend solar farm not too far from commencing operation...

South Australia’s second big solar farm gets generation licence, to start production

Image

The second big solar farm in already renewables-rich South Australia has won its generation licence from the state’s regulator, and plans to start commissioning the project in a few weeks, with full production scheduled for mid April.

The 108MW Tailem Bend solar farm – about 95kms south-east of Adelaide – is being built by Singapore-based Vena Energy, now part of Global Infrastructure Group, and has contracted all of its output to the federal government-owned generator and retailer Snowy Hydro for 22 years.

The $170 million Tailem Bend project will join the Bungala solar project near Port Augusta as the first large-scale solar projects to begin production in South Australia, as the emphasis gradually switches from large-scale wind and rooftop solar, to a more balanced portfolio of wind, solar, rooftop and growing amounts of battery and then pumped hydro storage.

The South Australian government has received 50 proposals for energy storage options.
Hoping pumped hydro wins big amongst the grant money...

And just out of interest, it is entirely possible to power South Australia by wind this afternoon Tuesday Feb 12 but AMEO (Australian Energy Market Operator) dictates a limit of wind supply (1,295 mw) Therefore wind power is curtailed (with nowhere to go) Gas is guaranteed a 300(?)mw bite of the market to "ensure stability"......I thought that was what the big battery is really good at...stability.

South Australia gets 50 new grid-scale energy storage proposals


The South Australia state government says it has received more than 50 proposals from energy storage developers keen to tap into a new $50 million scheme that will help navigate the local grid as it moves beyond a 50 per cent share of wind and solar and towards 100 per cent.

The state’s Liberal government is offering $50 million in taxpayer funds through its Grid Scale Storage Fund as it looks to expand its energy storage options, which have so far focused on the highly successful Tesla big battery at Hornsdale (owned and operated by Neoen), and the newly completed Dalrymple North battery on the Yorke Peninsula, and some household schemes,

The fund was formally launched in November and applications for projects ranging from big batteries, to pumped hydro, solar thermal, hydrogen and other forms of storage were due last Thursday.

I'm hoping that in the not too distant future we have an over-supply of wind/solar combined with storage that means we can rely on it for 100% of generation along with having excess to sell interstate.

Thats today......I dont just mean Tuesday Feb 12, I mean "the current time in South Australian history".

Daily average power usage (business hours) 1600 mw. (2000mw in summer, 3400mw at heat wave peaks)

Current wind farm capacity 2000mw (soon to be 2200 with the Lincoln Gap wind farm opening Q1 2019)

Current solar capacity 800mw (combined home panels and solar farms) This will rise substantially in the coming years, about 250 mw in 2019 alone just from new solar farms.

Of course these numbers relate to "maximum capacity" so if the wind is not blowing or the sun is not shining.....but of course if both are generating tons of power then the excess can, and is, being exported.

Storage projects will lessen our dependency on (expensive) natural gas a power source and on our dependency on interstate connectors during heatwaves.

Yeah, getting that storage up and running is the kicker. Plus we need excess capacity to account for events such as needing to ramp up desalination.

The entire output of the Hornsdale wind farm is contracted to the ACT government. It makes sense for an NSW interconnector so that power doesn't have to be exported via Victoria.

There are also several proposals for solar farms in that part of the mid-north. A new high-capacity transmission line will help to make them more viable so that they aren't limited in their maximum output by the network's capacity to carry it to customers. I believe the interconnector between Berri and Mildura is limited sometimes by the ability to supply both the Riverland and the interconnector on the SA side, or Sunraysia and the interconnector on the Victorian side if there is high demand within the supplying state as well as to transfer electricity interstate.

A little '"explainer" article on the proposed expansion of the SA-NSW electricity interconnector.
