Solar Reserve's website has not been updated with the news that they aren't going to build it yet.

I wonder if it still has the money lent/given by state and federal governments and can be made to give it back if they don't deliver their end of the deal. SA government now has to buy its future electricity from someone else.

AGL is proposing a pumped hydro facility at a mine located between Mt Barker and Murray Bridge.
From In Daily
Pumped hydro future planned for Kanmantoo's big pit

Australian energy generator AGL has secured the right to develop, own and operate a 250-megawatt pumped hydro energy storage project at Hillgrove Resources Limited’s Kanmantoo copper mine in the Adelaide Hills.

The contract allows AGL to transform their Kanmantoo open pit mine into a pumped hydro facility, while Hillgrove will retain processing and mining rights outside the Giant Pit.

AGL’s Executive General Manager of Wholesale Markets Richard Wrightson said the signing of binding agreements was the start of a multiple stage process to progress the project, including the lodgement of a development application in 2020.

“If we proceed and the project is approved, it would be an important addition to our technology mix in South Australia, where we have significant wind and thermal generation,” he said.

“It would help us to meet the changing needs of the South Australian energy market, in which energy storage assets are likely to be needed to provide dispatchable capacity as renewables generation increases over coming years.

“If all approvals are received, we expect the project to be complete and operating by 2024.”

This is the fifth proposed pumped hydro project in recent years....the South Australian government is currently assessing the other proposals to see which one (or ones) they will support.

The other proposals are :
1) Highbury Pumped Hydro (in the Adelaide Hills behind the Modbury/Tea Tree Gully area)
2) Goat Hill (Port Augusta)
3) Cultana (Whyalla)
4) Baroota (30 kms north east of Port Germein in the southern Flinders Ranges)

With the failure of the Solar Reserve Port Augusta proposal, there is a great opportunity for South Australia to grasp the economic opportunity for "storage" to add to the mix of renewable energy.

Should 2 or 3 of these proposals get up, then South Australia will have a chance to become "energy self-sufficient", lessening the reliance on interstate connectors and gas for energy when renewables are low.

Also its a chance for the South Australian Liberal government to show some leadership on the transition to "clean energy", not just piggy-backing on the previous Labor government's initiatives.

Oooops......forgot one other pumped hydro proposal !

- Middleback Ranges (west of Whyalla) using a disused mine. This is part of Gupta's plans.

Lincoln Gap wind farm, near Port Augusta, has started adding power to the grid. A few financial issues going on in the background.
From Renew Economy
Lincoln Gap wind farm delivers first power to grid as it deals with Senvion issues

The 212MW Lincoln Gap wind farm, located near Port Augusta in South Australia, has exported its first energy generation as project owner Nexif Energy said it had intervened to keep the project on track while Senvion sorts out its financial problems.

The Lincoln Gap wind farm is one of the biggest new renewable energy developments in the state, and one of a bunch of new projects that will likely take the share of renewable energy to around 70 per cent within a few years.

Lincoln Gap will combine the wind farm with a 10MWh battery storage installation, which could be expanded over time. The first of the Fluence batteries arrive tomorrow, and the installation will be complete by the end of May, project manager Andrew Houston told RenewEconomy.

Interesting article from Renew Economy discussing issues surrounding power contracts when the wholesale price of electricity goes "negative" and power is unable to be exported east due to maintenance on the interstate connectors.
South Australia solar farms switch off as prices fall below zero

The two biggest solar farms in South Australia were switched off for long periods this week as wholesale prices fell below zero – the result, apparently, of new “zero price clauses” in power purchase contracts.

As RenewEconomy reported on Tuesday, and updated on Wednesday, wholesale prices in South Australia fell below zero for extended periods on Tuesday (nearly six hours), and on Wednesday (nearly four hours).

This was the result of high wind and solar output, as well as relatively low demand, and export limits (down to 50MW) on the main link to Victoria because of maintenance works, which meant that excess renewable production could not be traded interstate.

Image

As Dylan McConnell, from the Climate and Energy College in Melbourne, points out, and illustrates with the graph above from the OpenNem resource, the state’s two biggest solar farms both switched off power on Wednesday.

The Bungala One and the semi-complete Bungala 2 projects cut output from around 1030am, ahead of the anticipated zero pricing event, while the newly-complete Tailem Bend solar farm cut power off on both Tuesday and Wednesday from around 11am as the prices hit zero. Both projects were offline for nearly six hours on Wednesday.

Both the 220MW Bungala projects and the 95MW Tailem Bend projects have long term power purchase agreements with Orign Energy and Snowy Hydro respectively.

That looks like a good argument for the NSW interconnector, since the NSW prices went UP during that period (and Victoria's looks to have been stable).

Blow me down dead but I'm posting an article on renewable energy from a News Corp paper..........well it is The Advertiser (who in general don't want to shit in their own backyard.................their eastern states masters will do that for them)

I doubt whether this will turn up in The Australian or The Daily Telegraph or The Sun herald with such a positive note.

Remember Rupert Murdoch hates renewables and encourages his journalists to write articles "disputing" the facts of global warming and they dont want South Australia to succeed with the conversion to renewables because "everyone else will do it" and dont forget that that Sydney's Daily Telegraph once ran an article describing South Australia as "Australia's Gaza strip"

Anyway the article is defintely a good read (with a nice map of the proposed NSW interconnector)
Solar farms to gain as SA-NSW powerline project nears decision time

Solar energy projects worth billions of dollars and hundreds of jobs stand to gain from construction of the NSW-South Australia electricity interconnector.

The most advanced project, Solar River, is close to finalising funding and a deal for purchase of energy it generates from its farm near Robertstown.

The interconnector would “help unlock the entire region for solar”, Solar River chief executive Jason May said.

“We’ll be making an announcement shortly about a power purchasing agreement which is for many years,” he said.

“We’re very happy.”

The planned $1.53 billion interconnector is now being considered by electricity authorities with proponent ElectraNet aiming to have it up and running by 2022.

The transmission company estimates it will cut $66 a year from SA residential customers’ bills.

The State Government, which backs the project, says benefits will be even broader.

“Not only will the nation-building interconnector deliver cheaper electricity to SA households but it will attract new investment in renewable energy projects that will create good jobs along its 900km route,” Energy and Mining Minister Dan van Holst Pellekaan said.

“The 900MW SA-NSW interconnector will be a freeway for cheaper, cleaner electricity whilst improving reliability of supply in both states by closing the loop on SA’s connection to the national grid.”

Four huge solar farms — three in SA and one in NSW — are planned on the route of the line which stretches from Robertstown in SA’s Mid North and Wagga Wagga in NSW.

ElectraNet chief executive Steve Masters said the route passed through areas designated by the Australian Energy Market Operator as renewable energy zones.

“Future development of renewable energy projects in the Mid-North of our state is largely dependent upon having additional interconnection,” he said.

“The proposed pathway for Project EnergyConnect (the SA-NSW interconnector) has been optimised to align with those renewable energy resources.

“What is clear from the transitioning Australian energy market is that we can’t afford to be ‘just in time’ with transmission.”

Battery at Lake Bonney wind farm is running behind schedule.
Tesla big battery at Lake Bonney wind farm faces connection delays

The latest Tesla big battery to be installed in Australia’s main grid – at the Lake Bonney wind farm in South Australia – is facing connection delays and is now not likely to be completed until the September quarter.

Infigen Energy, which is installing the 25MW/52MWh battery, using Tesla Powerpacks, at the 275MW Lake Bonney wind farm, had expected the first stage of the battery to be completed in February and the second stage in May.

But in its first quarter production report, released last week, Infigen reveals that while the “physical installation” of the $38 million battery is substantially complete, including the inverters and related balance of plant, connection issues are still being worked through.

Image

“Studies are continuing between Infigen, the market operator and the network service provider in relation to finalising connection and access to the electricity grid,” Infigen says in its statement.

“Based on progress to date, full commercial operation of the BESS is now expected in Q1 FY20.” Which is the September quarter. As recently as February, the company said the battery should be commissioned in the current quarter.

Infigen is not the only company facing delays due to connection issues with either the market operator, the local networks service provider, or both. Connection costs and delays have caused mayhem in certain parts of the market, causing cost blowouts in a number of projects across the country.

Another battery proposal for Port Augusta.
CellCube to build huge grid scale vanadium battery in South Australia

Renewables firm Pangea Energy and vanadium battery producer CellCube have signed an agreement to build a 50MW/200MWh battery storage system alongside a solar farm in South Australia.

Construction of the grid-scale battery is expected to begin before the end of the year, with plans to be operational in 2020.

Pangea Energy is part of Sen Tek Energy Solutions, a multinational renewable energy project developer in South East Asia. It signed the letter of intent with Canadian energy storage systems manufacturer CellCube this week.
