South Australia’s new solar energy plan – an international first

Reuters 4th Feb 2018, South Australia’s state premier Jay Weatherill announced a plan on Sunday to create a network of 50,000 home solar systems backed by Tesla Powerwall batteries, ahead of a state election in March.

“We lead the world in renewable energy with the world’s largest battery, the world’s largest solar thermal plant and now the world’s largest virtual power plant,” he said in a televised interview from the state capital of Adelaide. “The size of it is the reason why it’s going to be a success.” The project would begin with a trial on 1,100 public housing homes, the government said on its website.

South Australia’s renewable energy powerhouses to come – Whyalla and Port Augusta

Whyalla and Port Augusta could be a renewables powerhouse, says local mayor, ABC North and West By Tom Rohde  , 4 Jan 18

SA’s clean-energy projects

  • A hybrid power station is being built at Coober Pedy. The hope is that the outback community can be powered solely by solar, wind and diesel energy
  • Investors have funded a $300m solar battery-power plant at Roxby Downs
  • A wind, solar and battery farm is planned at Crystal Brook in the state’s mid north
  • A 100 megawatt solar powered facility is being built at Tailem Bend
  • US-based company Solar Reserve is seeking federal support for a $650 million solar-thermal project in Port Augusta
  • Zen Energy wants to build a solar power plant in the Upper Spencer Gulf

Whyalla Mayor Lyn Breuer said she hoped her city could team up with Port Augusta 80 kilometres away to make the plan a reality.

Regional South Australian cities have seen several energy projects announced over the past year, with construction on a new solar thermal power station in Port Augusta to start early this year.

In October last year, Whyalla steelworks owner Sanjeev Gupta announced that he had approved a plan worth up to $700 million for solar, battery storage and pumped hydro, with 200 megawatts of solar photovoltaics at Whyalla……..

Port Augusta’s mayor Sam Johnson said he believed the region was already becoming a hub for renewable energy.

“Port Augusta will, and I believe actually is becoming the renewable capital of Australia and there’s no doubt that Whyalla is a direct link into that.

“There’s some really great synergies between Port Augusta and Whyalla in what’s becoming a new and exciting industry.”…. http://www.abc.net.au/news/2018-01-05/sa-cities-could-become-australian-renewable-energy-centre/9306318

World’s first fully solar-powered train on the New South Wales North Coast

World-first solar train now leaving the platform in Byron Bay with zero emissions, ABC North Coast , By Bruce Mackenzie, 17  Dec 17,  What is claimed to be the world’s first fully solar-powered train is operating on the New South Wales North Coast.

A refurbished 70-year-old ‘red rattler’ is running on a three-kilometre stretch of disused rail line at the popular tourist destination of Byron Bay.

It made its maiden trip yesterday with almost 100 passengers on board.

Electric bus solar system

The $4-million project is the brainchild of multi-millionaire businessman Brian Flannery, who owns a resort in the area.

“Hopefully it attracts people to Byron Bay,” Mr Flannery said.

“I think international tourists will come here to have a look at this world’s first solar train.

“So let’s see, in five years’ time they’ll probably still say I’m mad, but it’s a bit of fun.”

Tim Elderton, from the Lithgow Railway Workshop, was tasked with building curved solar panels and a battery system to power the train.

“Of course the major difference is it’s got solar panels on the roof so it can recharge itself.

“For those cloudy days we’ve also got 30 kilowatts of solar panels in this [station’s] roof here so we can also plug it in.

“On a sunny day like today we can do about four or five trips before we have to plug it in.”……..

Tram infrastructure a possibility

Longer trips than this one — 10 minutes to cover three kilometres or so — would require regular recharging stations along the route, but Mr Flannery said the technology might be suited to inner-city trams.

A lot of the tram networks of course have overhead wires and they’re electric but they’re powered off the grid from overhead,” he said.

“But in a case where you want to build a tramline without that infrastructure, I think you could.

“At various stations you could top the train [or tram] up.” http://www.abc.net.au/news/2017-12-16/world-first-solar-train-the-brainchild-of-byron-bay-millionaire/9265522

Queensland election is critical for solar energy, and for electricity consumers

Queensland poll could be a show-stopper for solar, and consumers http://reneweconomy.com.au/queensland-poll-could-be-a-show-stopper-for-solar-and-consumers-11958/ By Giles Parkinson & Sophie Vorrath on 24 November 2017 Dirty versus clean; old versus the new; fossil fuels verses renewables; expensive energy versus cheap. There has rarely been so much at stake for an industry as there is in Saturday’s state election in Queensland, and the result is far from clear.

Current polling from Galaxy puts the ALP on track to win the required 47 seats for a majority, but as the Brisbane Courier-Mail reports, this will hinge on a number of factors, including unpredictable preference flows from One Nation supporters.

As at the federal level, politics in Queensland has been heavily focused on energy in the run-up to Saturday’s poll.

The Labor Palaszczuk government – which has a 50 per cent RET by 2030 for the state – has been campaigning strongly around renewables, with a particular focus on increasing rooftop solar uptakeas a way to cut power costs for businesses and homes around the state.

The new policies, launched in late October as part of the Palaszczuk government’s $2 billion Affordable Energy Plan, will offer no-interest loans to consumers wishing to invest in rooftop solar and battery storage, but lacking the up-front capital to do so.

They will also work to give landlords and renters equal access to solar, through a trial initially involving 1000 rental households. Queensland energy minister Mark Bailey said the rental solar scheme had the potential to save tenants up to 10 per cent off their annual bill, or up to $150 a year, while landlords could get a rebate of up to $520 per year.

On large-scale renewables,  as we reported here, Labor, has promised to follow through on a program already underway to underwrite 400MW of renewable energy projects.

Following on from this, it has committed to support a further 1000MW of renewable energy projects via a new government power company; and to look to construct new transmission infrastructure in Northern Queensland that would unlock a vast new province of wind, solar and hydro power projects.

On the other side of the political divide, the LNP conservative coalition that is seeking to replace the current Labor government has made its intentions on energy clear: the end of renewables incentives; government money for a new coal generator in north Queensland; and support for the Adani coal mine.

The LNP is also claiming a huge reduction in consumer bills: $160 a year for two years, followed by savings of up to $460 a year in 2020.

But this is largely a mirage, as energy analyst Hugh Grant has pointed out. He noted that the only parties with policies that would deliver price reductions were the Greens, and Labor.

Not that Queenslanders got to read about that anywhere – apart from RenewEconomy, the local media refused to publish the results, as Michael West points out in this piece.

In the Conservative corner in the fight for new coal is federal minister for resources and northern Australia, Matt Canavan, who – recently restored to his portfolio – is as keen as ever to use the federal government’s Northern Australia Infrastructure Facility to help fund a new coal-fired power plant in Queensland’s north, as well as to get the Adani coal mine and port project off the ground.

One Nation is also keen to build a coal-fired power station west of Townsville, with party leader Pauline Hanson pledging to commit $1.5 billion to the project, which she wants built in Collinsville – a former coal hub of the state that is more recently turning to large-scale solar.

In fact, according to data gathered for RE’s Renewable Energy Index, the North Queensland region has more power generating capacity under construction than the entire state of NSW, and almost as much as Victoria, South Australia and Western Australia combined.

Meanwhile, Queensland home and business owners are leading the country – which in turn is leading the world – in rooftop solar uptake.

A Climate Council report last month showed that almost one third (31.6 per cent) of all Queensland homes now have solar panels, which puts the state ahead of South Australia, at 30.5 per cent, and Western Australia at 25.4 per cent.

What’s more, there are 14 postcodes in the Sunshine State alone where more than 50 per cent of households have rooftop solar, including the the Moreton Bay region town of Elimbah, where an impressive 63 per cent of homes have PV panels on their roofs.

The Australian Solar Council – newly rebranded as the Smart Energy Council – aren’t resting on their laurels, though. The peak solar industry body is spooked enough about a possible LNP victory that is has launched its own major election campaign, urging voters to put the Coalition last.

“Queensland voters face a stark choice at the election tomorrow,” the SEC said in an email to members on Friday:

“A new polluting coal-fired power station or a solar thermal plant providing 24-hour solar power; no new large-scale renewables and massive job losses or 1,000 megawatts of new large-scale renewable projects in regional Queensland; and a National Energy Guarantee that delivers the longest solar eclipse in history or sensible national energy policy.”

Australian Solar Council launches campaign againstQueensland’s Liberal National Party

Solar industry launches big campaign in Queensland poll against LNP http://reneweconomy.com.au/solar-industry-launches-big-campaign-queensland-poll-lnp-59401/ By Giles Parkinson on 17 November 2017  The Australian Solar Council – the peak body for the country’s solar industry – has announced a major advertising campaign against the Liberal National Party coalition in the Queensland election campaign, saying the future of the industry is at stake.

The ASC says it is spending “hundreds of thousands” of dollars in the first stage of its campaign, which will include TV, designed to highlight the implications for the solar industry if the LNP win power.

“It is a huge step for the Australian Solar Council to do political advertising, but solar companies are concerned,” says John Grimes, the chief executive of the ASC.

Liberal National Party policies present a direct threat to profits in Queensland’s renewables industry.”

 Grimes told Reneweconomy that campaign was launched because it was felt that the issue – essentially one of solar versus coal – had not got the prominence it deserved.

“The reality of what’s at stake is not well understood, we have got to shake people up,” Grimes said.

“The implications of a Queensland LNP government that abolishes the renewable target, abolishes the RET in Queensland and signs up to new coal fired power station is completely untenable. That’s why we are taking this action.”

The LNP has made clear it will remove all subsidies for renewable energy in the state, and focus instead on building a new coal fired power station in north Queensland – an idea that even other coal generation companies say is ridiculous.

Labor, on the other hand, has promised to reach “at least” 50 per cent renewable energy by 2020, and promised more funding for a first solar thermal plant with storage, more solar for schools, initiatives for renters and low income households, and a 400MW tender for solar and storage.

The result, however, is in the balance, with One Nation polling strongly enough to possibly win some seats, and provide the numbers to support the LNP in a minority government.

Grimes noted that there were more than 24 large scale solar projects under development, or committed, in Queensland, and a pipeline of at least double that.

“We right on the cusp of an energy transformation,” he said. “There is a whole lot of investment that will fall by the wayside if we get a change in government.

The ASC is also concerned about the LNP’s declared support for the proposed National Energy Guarantee, which critics say will end up supporting existing fossil fuel generators and effectively penalise and put a halt to renewable energy development. The National Energy Guarantee is really a guarantee for coal,” Grimes says. “It means delay, inaction and confusion for renewable energy. That’s untenable for Queensland’s solar industry.

“When the National Energy Guarantee was announced, the Australian Solar Council promised a pointed political campaign against it. We are making good on that promise through newspaper, radio and digital advertising in key marginal seats in Queensland.

“Thousands of regional jobs have been created by the solar boom, and billions of dollars are being invested in regional communities but the solar boom could turn to bust in the Sunshine State,” said Mr Grimes.

Record low electricity demand in South Australia, due to rooftop solar

Rooftop solar pushes South Australia to record low demand (again) http://reneweconomy.com.au/rooftop-solar-pushes-south-australia-to-record-low-demand-again-47836/By Giles Parkinson on 6 November 2017

The combination of growing rooftop solar installations, mild temperatures and sunny weather has pushed South Australia’s grid demand to yet another record low, this time shaving around 6 per cent off the previous low set just six weeks ago.

The new low was set just before 1.30pm in South Australia (just before 2pm on National Electricity Market time) when the minimum grid demand hit 554MW.

This shaved some 33MW off the previous low of 587MW set on September 17,which itself was nearly 200MW or 25 per cent the previous record low demand of 786MW set just a week earlier.

For six hours, according to the APVI solar map, rooftop solar PV provided more than 30 per cent of the state’s demand. For nearly three hours, rooftop solar provided more than 40 per cent of the state’s demand.  As we explore in this article here, rooftop solar provided 9.2 per cent of the state’s local generation in 2016/17 and would likely be more than 10 per cent if larger rooftop solar installations were included.

Within a decade, that share is expected to double to more than 20 per cent, at which times on days like this Sunday, minimum demand may actually fall to zero because of the amount of solar being generated.

The Australian Energy Market Operator, which includes these forecasts in a new report into the South Australia grid, suggests that by that time it will be necessary to store some of that excess solar for use later in the day.

The same situation may occur in West Australia, too, because of the amount of rooftop solar being installed in a small grid. The uptake of rooftop solar is accelerating because of high grid prices and the falling cost of solar technology, and grid demand fell in W.A. to an 8-year low last week.

“At these times, South Australia could store or export its excess generation to the rest of the NEM via the interconnectors, provided they are in service,” AEMO notes in its report.

“This, in turn, will provide market participants with greater opportunity to manage their energy use.”

AEMO noted, as it has previously, that South Australia is the first region in the NEM in which high rooftop PV penetration has caused minimum demand to shift from overnight to near midday – a transition that occurred five years ago.

Many argue this is a good reason to shift the “controlled load” of electric hot water systems from the night-time to the mid-day hours, particularly since the closure of the coal fired generators which could not be switched off at night and needed something to power during the night time.

However, problems with the nature of the metering, and the potential expense of the shift, are barriers to the migration of hot water systems to the day-time hours.

South Australia’s Whyalla to become a booming renewable energy hub

Whyalla steel city goes green with 1GW of solar and storage, http://reneweconomy.com.au/whyalla-steel-city-goes-green-with-1gw-of-solar-and-storage-92904/ UK billionaire Sanjeev Gupta has made good on his commitment to transform his newly acquired Australian steel business into a renewable energy powerhouses, announcing massive investments in solar and storage that will knock 40 per cent off his electricity costs.

Gupta said on Monday that he would build 1 gigawatt (1,000MW) of dispatchable renewables in and around Whyalla, where his major steel plant is located. This would comprise huge investments in solar, battery storage, pumped hydro and demand management.

He won’t stop there. Gupta is looking to repeat the dose – although with varying mixes and scale of renewables and storage – to power the company’s steel operations in Melbourne, Sydney and Newcastle. He said on Tuesday he wanted these bigger plants to be powered 100 per cent by renewable energy.

The initial development will see a proposed 80MW solar farm at Whyalla expanded to 200MW and completed by the first quarter of 2019.

Small-scale solar cutting $billions from electricity bills 

http://www.theage.com.au/business/energy/smallscale-solar-cutting-billions-from-electricity-bills-20171012-gyzf2c.html, Cole Latimer, 14 Oct 17,

Small-scale solar systems have cut wholesale electricity costs by up to half in the past 12 months, a study has shown.

The report by consulting firm Energy Synapse, commissioned by a community-based organisation Solar Citizens Australia, found solar photovoltaic (PV) installations in NSW had saved consumers up to $2.2 billion from May 2016 to April 2017

During this period, small solar PV systems are estimated to have generated 1540 gigawatt hours of power within the state.

The report says the volume-weighted average price of wholesale electricity would have been between $29 and $44 per megawatt hour higher than the actual average price for the period of $88 per megawatt hour.

The study found that small-scale solar had the largest impact during February, when record heatwaves were experienced, reducing the volume-weighted average price of wholesale electricity by between $119 and $258 per megawatt hour.

There has been a massive increase in renewable energy investment and construction this year. New solar energy generation has grown by 50 per cent globally, according to a report by the International Energy Agency. The IEA’s Renewables 2017 report says 165 gigawatts of new energy came online from renewables as a whole – including solar, wind and hydro power.

“We see renewables growing by about 1000 GW by 2022, which equals about half of the current global capacity in coal power, which took 80 years to build,” IEA executive director Fatih Birol said.

“What we are witnessing is the birth of a new era in solar PV. We expect that solar PV capacity growth will be higher than any other renewable technology through 2022.”

In Australia, there are more than 40 large-scale renewable energy projects that have either started, or will start, construction this year.

Clean Energy Council chief executive Kane Thorton said this represented an investment of more than $8 billion.

“These 41 projects will deliver over 4330MW of new capacity, which is crucial to increasing supply in the energy market, replacing old coal-fired generation that continues to close, and ensuring downward pressure on power prices,” Mr Thornton said.

There are 26 projects being built, and another 14 projects that have secured finance with the expectation that construction will start before the end of the year.

“We have already seen six times the investment value in 2017 of what we saw in 2016, and the new capacity will also help with energy security,” Mr Thornton said.

“In 2016, the combined capacity from all projects completed stood at 264.1 MW. This year 2210.2 MW of projects have been committed and 1881.2 MW are in construction with a whole financial quarter still to go.”

Solar power juggernaut is catching Australia by surprise

Australia’s solar juggernaut is coming – quicker than anyone thinks, [excellent diagrams and graphs] REneweconomy By Giles Parkinson on 13 October 2017 It is perhaps not surprising that the fossil fuel industry has hit the panic button and is pushing hard for the Turnbull/Abbott Coalition government to dump the proposed clean energy target and replace it with something that might be called a coal energy target.

They can see what’s coming – and there is probably no better way to describe it than a solar juggernaut.

The fact that solar will become the dominant energy source appears to be under no doubt, even the International Energy Agency admits it. And the CSIRO and AEMO appear to be in agreement that even behind the meter solar will account for around half of all demand by the 2040s or 2050s.

But what if it happened a lot quicker than that? Australia’s grid prices have jumped again to absurdly high levels, and this has lit a fire under the rooftop solar market, which will be followed by a major push by corporate buyers into the large-scale market. The solar sector could boom in ways not previously imagined.

 Huon Hoogesteger heads Smart Commercial Solar, a company specialising in rooftop solar for businesses that has experienced a doubling in demand in the last year or so, and a three-fold increase in the current year. He can’t see it slowing down.

At this week’s All-Energy Australia conference he was asked to speak about the implications of a continued solar boom in the Australian energy market, and what it means for incumbent fossil fuel generators, and others – particularly the storage industry. It was a fascinating insight.

First of all, it should be noted that Hoogesteger focused only on solar – so his observations take no account of the 4.5GW of wind energy already in the market, and the likely doubling of that capacity in coming years (particularly as it defies doubters and matches the falling cost of solar)………

Hoogesteger says most forecasts are based around a continued linear uptake of solar, that puts the country’s capacity at about 21GW in the mid 2030s……… Base on his experience, with a near doubling of just rooftop installations, the massive investment in large-scale solar, and the technology’s falling costs, along with high grid prices, he says it could happen a lot quicker than that……http://reneweconomy.com.au/australias-solar-juggernaut-is-coming-quicker-than-anyone-thinks-70985/

Australia’s rooftop solar boom now taking to business buildings

Above: Broadway shopping centre in Perth

The solar boom started in our suburbs, but now it’s moved out of home, ABC News, By Kathryn Diss, 28 Sept 17, Australian households have led the world in installing rooftop solar panels and now businesses are following suit as energy prices start to bite.

Nearly a quarter of the nation’s households have installed rooftop solar panels in recent years as consumers have looked for ways to offset their ever-increasing power bills.

But new research by consultancy firm SunWiz has found business solar installations have jumped 60 per cent during the past 18 months to 40,736 systems.

“It’s accelerated significantly in recent years and continues to be a popular investment for businesses wanting to take care of their electricity prices,” the company’s managing director Warwick Johnston said…….

Business backs renewables as politicians bicker

The research comes as federal politicians argue over what fuel source should be used to guarantee the nation’s future energy supply, with the east coast facing looming gas shortages……..http://www.abc.net.au/news/2017-09-28/solar-power-perth-businesses-energy-boom/8994314

Australia’s top 10 solar postcodes, and the top solar locations by state 

http://reneweconomy.com.au/australias-top-10-solar-postcodes-top-solar-locations-state-60359/

We know Australia is leading the world in per capita uptake of rooftop solar, with total installed capacity on homes and businesses this year soaring past the 6GW mark.

But which parts of Australia are leading the country? New data from the Clean Energy Regulator has revealed the latest ranking of Australia’s top 10 postcodes for small-scale solar installation (up to 100kW), with some interesting new additions.

As you can see below, the list this year features a few new entries, and a more diverse spread across the states, instead of being dominated by Queensland and Western Australia locales.

Both the new entries and the old stagers on the list span the suburban, regional and rural areas of Victoria, New South Wales, Queensland and Western Australia, with no entries this year from South Australia, Tasmania, the ACT or the Northern Territory.

In order from the top, the Queensland town of Bundaberg has again secured the number one spot, followed by new entries on the list, the Victorian suburbs of Werribee and Hoppers Crossing. Last year, no Victorian postcodes made the top 10.

According to the CER data, these three postcodes have accumulated the highest number of small-scale renewable energy installations since the small-scale renewable energy scheme began in 2001, each reaching around 17 000 installations as at 1 September 2017.

In fourth place, down from second place last year, is the WA suburb of Mandurah, where the local council is also pushing hard to install PV on government buildings – and just last week agreed to install a 200kW (not a part of the SRES) system at the local pool and sports centre.

The Queensland suburb of Hervey Bay follows, moving to fifth place from third last year. And another Victorian new entry, the semi-rural south-eastern suburb of Cranbourne, is in sixth place.

Bringing up the rear are regular place holders Caloundra and Toowoomba in Queensland, and new entries Wangara (WA) and Lismore (NSW), the latter of which makes the list probably due to the May switching-on of a 99kW rooftop PV system at the Goonellabah Sports & Aquatic Centre, as part of a major community-based and funded renewables campaign.

Despite some bigger commercial installations coming into play, the CER says the average size of the solar postcode installations is 5kW – which is also the average size, now, of a household rooftop solar system. This indicates the dominance, still, of residential uptake in these numbers, considering the SRES encourages commercial systems, too – up to 100kW in size.

“Over the last 10 years, 23 per cent more Australians have embraced rooftop solar,” the CER said in a release on Monday. “That’s one in five homes and businesses now generating their own renewable energy and reducing carbon emissions through rooftop solar.

As we reported here, Australia hit a milestone of 6000 megawatt (6GW) capacity across 2.8 million small-scale installations of renewable energy systems such as solar PV, solar water heaters and air source heat pumps. Nearly 100MW was installed in August, alone.

Interestingly, while no South Australian suburbs on their own make the list, the entire state is setting all sorts of solar records, including a new record low for minimum demand – barely a week after the previous benchmark was set – with a fall to just 587MW on Sunday afternoon.

As Giles Parkinson notes, the record eclipsed the previous mark by nearly 200MW – with AEMO data showing minimum demand at 1.30pm of exactly 587.8MW, compared with the previous low mark of 786.42MW posted last Sunday – thanks to moderate spring temperatures, combined with the state’s more than 700MW of rooftop solar producing 538.54MW at the time of minimum demand.

“That is a phenomenal share of 47.8 per cent of the state’s electricity demand being met by rooftop solar (compares with 36 per cent in the previous record last week) and is clearly a record for South Australia, and for that matter in any large grid anywhere in the world,” Parkinson says.
