It only lasted for 10 minutes, but renewables provided 50.2% of the electricity available on Australia’s National Energy Market in the first week of November. The NEM supplies electricity to Queensland, New South Wales, Victoria, South Australia, and Tasmania. The Northern Territories and Western Australia have their own energy grids. “We will start to see this happening more frequently. It was just a snapshot in time, but it’s indicative of an underlying trend in the system,” Dylan McConnell of the University of Melbourne’s Climate and Energy College tells The Guardian.

The milestone was spotted using an online tool developed by McConnell called OpenNEM that monitors the grid in real time using data from the Australian Energy Market Operator. During those 10 minutes, solar power led the way, providing 32.5% of the available electricity. Wind was next at 15.7%, and hydro provided 1.9%. There are more than 2 million small rooftop solar systems in those 5 Australian states and they provided 72% of the solar power, while solar power plants contributed the other 28%.
Kane Thornton, chief executive of Australia’s Clean Energy Council, says “It is a fantastic achievement to have more than half of the National Electricity Market powered by renewable energy, and it’s worth celebrating.

Both SA and the UK have run on purely RE energy before that (UK may have had some nuke boost, I forget.)

Starting to get to significant part of the grid anyway.

Within several months, the Hornsdale Power Reserve will be expanded by 50% to 150 MW of power and 193.5 MWh of capacity
The renewable energy company Neoen announced today an expansion of its battery energy storage system Hornsdale, Australia (built by Tesla in 2017), which is by the way the world’s largest lithium-ion power reserve (100 MW/129 MWh storage capacity).
The site used for better utilization of solar and wind generation as well as the support of the grid, turned out to be highly successful, reportedly saving consumers more than $50 million AUD (US$35 million) during its first year of operation.
Now, Neoen and Tesla will add 50% more power and capacity so, after the expansion, the Hornsdale Power Reserve will be:
150 MW of power (+50 MW)
193.5 MWh of capacity (+64.5 MWh)

What is impressive that it made 50 millions dollars in the first year is that the project cost 90 million to build.... The SA government pay Hornsby a few million for them to keep some of the battery capacity in case of a power blackout. It more than half paid for it self in the first year, every State needs one of these Batteries to begin with and more... It will save Millions and in turn be cheaper for us. :purple

I would rather have seen another Big Battery built elsewhere. I wish Geodynamics Ltd would get off its arse and develop the excellent geothermal energy in the Cooper Basin, LOTS of clean energy available that way.

Be nice if the long runs of high tension wires conducting electricity over vast distances could be made much more efficient, save huge amounts of power.

now that you can have small, wind/solar plants with batteries ,no real need for long power lines, just heaps of macro grids... :purple

I was thinking more the state interconnectors. I agree remote places should have solar+wind+storage with diesel for backup.

And that’s where Solar should be, on roof tops; generate where the load is and not on arable land.
Not a great supporter of wind generation because of visual and noise pollution etc, lax govt conditions on remedial of land.

Maybe, the Greenies need to look at banning cobalt being mined from the seabed - I believe most of the cobalt is in the ocean.

Re: SA Battery will get bigger in March

Postby DonDeeHippy » 17 Jan 2020, 08:53

https://cleantechnica.com/2020/01/16/ne ... -in-march/

Renew Economy reports that Neoen, a French renewable energy developer, is hoping to have the additional capacity at Tesla’s big battery in South Australia online in March. This is already the largest lithium-ion battery on the planet and Neon has already planned to add more capacity to the battery that will focus on new grid services such as “inertia.” It could also supply up to 50% of the state’s inertia needs while it moves forward with its goal of net 100% renewables by 2030.

For those who don’t understand what inertia is, it is a service that stabilizes the grid when the electricity supply and demand fluctuate. Neoen says that this battery will be upgraded with Tesla’s Virtual Machine Mode, which will allow the advanced power inverters to emulate existing inertia services that are currently being supplied by an aging fleet of fossil fuel power plants. “The level of inertia that would be provided by HPR (Hornsdale Power Reserve) could match half of the total needs of South Australia.”

Currently its 129 MWH and will increase to 185 MWH, considering this is privately owned, id say all those that said it couldn't make money are wrong..... After all in it's fist year it made over 50% of it's cost
Every state should have one, it will bring down costs but as our electricity is now owned by Corporations I doubt if we will see the savings.... :purple

It akes money and saves consumers money by evening out the flow of wind energy, storing it when supply outruns demand, supplying it when demand outruns supply.

I want to see the good hydrothermal energy of the Cooper Basin developed! I would also like to see real hydro storage—batteries are always limited—and wave and tide energy developed. Plenty of big waves in the Bight and the Gulfs in SA must amplify tides.

I know some attempts to harness tidal energy didn’t work very well—some deniers on Twitter were happy to point that out :rofl —but was a while and many failed experiments before the Wright Bros demonstrated successful heavier than air flight.

MeyGen Tidal Power Facility Exported 13.8 GWh Of Electricity To The UK Grid In 2019

Last year, that facility exported 13.8 gigawatt-hours (GWh) of electricity to the grid, enough to power 3,800 typical homes in the UK. That’s about double the output of the MeyGen facility the prior year, according to CNBC. Simec Atlantis Energy, which owns and operates the MeyGen installation, says Phase 1A of the project uses four 1.5 megawatt turbines.

“The project will…..provide an investment opportunity for commercial debt and equity providers to invest in tidal stream projects,” the company says. “In addition, Phase 1C will create an estimated 5,300 full time roles, repurposing jobs from the oil and gas sector and placing Scotland at the forefront of an estimated 25GW global export market for decades to come, as well as significantly reducing LCOE.”

Tidal Power Is Growing
Recently, Scottish firm Nova Innovation was awarded a contract to install undersea turbines in the Bay of Fundy off the shores of Nova Scotia. That project is being partially funded by the Canadian government. Another innovative company, Orbital Marine Power, says it is developing the world’s most powerful tidal stream generator. It uses a unique floating platform to support the turbine below it, eliminating the need for specialized ships to install the system. Orbital expects the first O2 tidal turbines to begin operations this year.

It's a very important first step to having uninterrupted renewable energy, as long as there are tides then it will work, as most of the Australian population is on the coast these power plants should be installed everywhere... Maybe let the Scott's and Canooks iron out the details first then go for it :) :purple

That article also made me think of the wave Generators

https://cleantechnica.com/2019/11/09/wh ... ean-waves/

What Is Bright Yellow, Weighs 826 Tons, & Makes Electricity From Ocean Waves?

There is also an enormous amount of untapped energy in ocean waves. The US Energy Information Administration says the theoretical annual energy potential of waves off both coasts of the United States is 64 trillion kilowatt-hours — equal to more than 60% of the total amount of electricity generated in America in 2018.

“The buoy is shaped like an ‘L’ with a long open chamber that sits below the water line, and a turbine above the water. As water enters the open chamber it forces air upward, which turns the turbine, generating electricity. When the water recedes, it creates a vacuum and air rushes in to fill it, keeping the turbine spinning, and the cycle repeats.” The Wells turbine that makes all this possible is the only moving part of the OE 35. “The beauty of the OE design is its simplicity. Having only a single moving part substantially increases its reliability in the often hostile ocean environment,” the company says.

this with Tidal power, wind and solar ,few batteries for peak times and you have a viable alternative of burning fossil fuels..
Every day some new person or company is coming up with new ways to stop poisoning us and our land, it's great to follow what's happening... :purple

there used to be a company trying to set up tidal energy of the coast of the Illawarra. I think they gave up after a couple of years.

Yeah it looks like it was set up about 15 years ago and 2 years ago they took it into deep water and sunk it.. Cant find any info on if it actually worked or not

https://en.wikipedia.org/wiki/Oceanlinx

2010 - MK3 prototype launch at Port Kembla and successfully grid connected for the first time under the management of the new CEO, Ali Baghaei
2010 - Unforeseeable extrem weather conditions broke the MK3 prototype moorings at Port Kembla. It was successfully and safely recovered
2013 - Oceanlinx launched the world's first 1MW wave energy converter unit greenWAVE
2014 - Damage to greenWAVE prototype during the towing operation and is left stranded near Carrickalinga, South Australia
2014 - Oceanlinx enters receivership; the technology, IP, brand and trademark were sold to Wave Power Renewables Limited
Since 2014 - Wave Power Renewables Limited continue to develop the technology

Looks like it all went wrong.....

The oceans are pretty powerful, huge expanse over which storms can grow very strong, waves very high. But we will master the oceans enough to get energy from them.

Room temperature superconducing materials have recently been discovered. Too early to say if they can be processed into long runs of ‘wire’.

Interesting but little mention is made of selling power into the grid at night from solar charged battery storage or the dirty denialist politics working behind the scenes for and on behalf of fossil fuel/oil/gas interests.
We also need to face the fact even academic economists have yet to figure out how to calculate the eventual costs of not moving to new power sources.
