Renewable-based energy system cheaper than fossil fuels – new research
New modelling shows renewable-based system cheaper than fossil fuels, REneweconomy, (good graphs) By Giles Parkinson on 14 March 2016 New modelling from a group of engineers, energy analysts and IT experts in Western Australia shows that a high penetration renewable energy system would be cheaper based around existing fossil fuel generation.
The modelling, known as SIREN, looks at the West Australian grid, known as the South West Interconnected System, and shows that an electricity system with 85 per cent renewable energy will be cheaper than “business as usual” – an average of $124/MWh compared to $127/MWh – and around the same price as current costs.
A system with 91 per cent renewable energy penetration would be slightly higher ($136/MWh), while three separate scenarios for 100 per cent renewable energy would be more expensive (ranging from $157/MWh to $164/MWh).
The modelling assumed that there will be 6,000MW of wind and 3,000MW of solar PV in the high renewables scenarios, and 5,000MW of wind and 2,000MW of solar PV in the 100 per cent renewable energy scenarios. The difference in the 100 per cent renewables scenario is the addition of 1.2GW of solar thermal and storage.
The SIREN modelling template will soon be used for an updated assessment and costing of the main grid in Australia, the National Electricity Market. “We intend to use this to lobby government and show (utilities) Western power and Synergy what we have found, and what they can do,” says Ben Rose, one of the authors.
Some may quibble with the fact that it compares new investment in each scenario, but the fact remains that most of the current generation in W.A., particularly its coal assets – and indeed the rest of Australia – is reaching its used-by date and will need to be replaced by 2030. Yet, says Rose, few politicians are addressing this issue.
The results are also based on relatively conservative technology cost assessments included in the AETA survey done by the Bureau of Resource and Energy Economics.
Many of these costs, particularly the solar thermal costs used in the 100 per cent renewable energy scenarios, are expected to come down quickly, and well below the 2025 forecasts included by AETA. Most of the technologies are already cheaper than those forecasts……….http://reneweconomy.com.au/2016/new-modelling-shows-renewable-based-system-cheaper-than-fossil-fuels-55032
Nuclear power is now redundant: dispelling the “baseload” myth
Dispelling the nuclear ‘baseload’ myth: nothing renewables can’t do better! Ecologist 10th March 2016 The main claim used to justify nuclear is that it’s the only low carbon power source that can supply ‘reliable, baseload electricity’, writes Mark Diesendorf – unlike wind and solar. But not only can renewables supply baseload power, they can do something far more valuable: supply power flexibly according to demand. Now nuclear power really is redundant.We have all heard the claim. We need nuclear power because, along with big hydropower, it’s the only low carbon generation technology that can supply ‘reliable baseload power’ on a large scale……
Underlying this claim are three key assumptions. First, that baseload power is actually a good and necessary thing. In fact, what it really means is too much power when you don’t want it, and not enough when you do. What we need is flexible power (and flexible demand too) so that supply and demand can be matched instant by instant.
The second assumption is that nuclear power is a reliable baseload supplier. In fact it’s no such thing. All nuclear power stations are subject to tripping out for safety reasons or technical faults. That means that a 3.2GW nuclear power station has to be matched by 3.2GW of expensive ‘spinning reserve’ that can be called in at a moments notice.
The third is that the only way to supply baseload power is from baseload power stations, such as nuclear, coal and gas, designed to run flat-out all the time whether their power is actually needed or not. That’s wrong too.
Practical experience and computer simulations show it can be done……… Continue reading
Greens plan for solar shade in Brisbane’s King George Square
Brisbane council election: Greens promise ‘solar shade’ in
, Brisbane Times March 9 2016 Cameron Atfield It’s long been the civic centre of Brisbane, but now King George Square has again found itself at the centre of Brisbane’s council election campaign.
Greens lord mayoral candidate Ben Pennings has unveiled a plan to cover the square in solar shading, which would come equipped with sockets for people to charge their phones in the shade. Below – solar shade , Arizona University
The Greens want to introduce solar shade, similar to this at Arizona State University, to Brisbane’s King George Square
Mr Pennings said the solar panels would generate 100,000 kilowatt hours a year to help charge City Hall, which he said would save Brisbane City Council $20,000 in annual electricity bills.
“The Greens’ plan for King George Square embraces this century rather than looking to the past of roped-off grass,” he said. “A one-off investment of $2.5m will shade King George Square with solar panels.”Residents can relax in the shade and use the power to charge their phones, tablets or laptops.
“New seating will allow people to recharge on their own or connect under the shade in small groups.”………http://www.brisbanetimes.com.au/queensland/brisbane-council-election-greens-promise-solar-shade-in-king-george-square-20160309-gneylr.html
Canberra’s renewable energy now paying dividends
ACT government leads the way on renewable energy March 6 2016 The Canberra Times
The ACT government’s commendable commitment to renewable energy has the potential to deliver for this community on a number of levels.
The first, and most obvious, is that Canberrans have shifted further away from dependence on fossil fuel generated electricity than almost any other mainland state or territory.
The second is that while the ACT government’s 2015 commitment to 100 per cent renewable energy by 2025 was initially mocked in some circles, the aspirational nature of that goal is now paying dividends.
The territory is expected to reach 60 per cent of power generation from renewables by the end of next year and 90 per cent by 2020. Both of these figures are impressive given the federal government’s much more modest target of 23.5 per cent from renewables by the end of the decade.
That Canberra’s commitment to this path occurred at the same time the federal government was openly hostile to investment in renewables and after former treasurer Joe Hockey said wind farms were a blight on the landscape makes it even more remarkable.
The announcement that, as a result of the “reverse auction” process initiated by the territory, Sapphire has been awarded a contract to build a local 100 megawatt hour windfarm for completion by April 2018, is the latest in a number of positive steps…….
With the Royalla 20 megawatt solar power plant in operation since September 2014 and the 13 megawatt Mugga Lane solar park expected to come on line this year, considerable expertise is already available on the solar power front as well……
It is remarkable that these achievements have been delivered while, at the same time, local power consumers continue to enjoyed the lowest electricity prices in the nation. http://www.canberratimes.com.au/comment/ct-editorial/act-government-leads-the-way-on-renewable-energy-20160304-gnawvc.html
Western Australia’s largest solar installation at Perth shopping complex
WA’s largest solar installation generating one-third of Perth shopping centre’s power http://www.abc.net.au/news/2016-03-03/solar-panel-installation-broadway-shopping-centre-wa-largest/7217984 By Kathryn Diss A shopping complex in Perth’s western suburbs is generating one third of its power from the sun after undertaking Western Australia’s largest solar panel installation on its roof.
The Broadway Fair complex has installed 948 solar panels with the capacity to generate 312 kilowatts of power. Broadway Fair general manager Paul Avon-Smith said the move would save the complex about $20,000 a month in power bills, which could be put towards funding capital works.
“We were looking for soft approach for the cost of doing capital works,” Mr Avon-Smith said. “It gives us an alternative to help cushion rent increases and price rises for our tenant base in a pretty tough market, but allows us to finance crucial capital works. “So that allowed us to do a roof replacement project, plus put the solar in, with there being no upward pressure on our rents for tenants.”
Infinite Energy installed the system at a cost of $600,000.
Managing director Aidan Jenkins said the huge fall in the cost of solar panels in recent years has meant the business model now stacked up for commercial-sized installations. “Solar currently represents the cheapest way to generate electricity, so we will start to see these type of systems become the norm over the next couple of years.”
Government grappling with ‘tsunami’ of solar installations
Large-scale solar installation poses a big challenge for the Government, which currently has too much available power in its network. The rapid uptake of rooftop solar panels has been a big contributor to the problem, displacing traditional sources of power like coal and gas.
Energy Minister Mike Nahan has been an outspoken supporter of solar power and said the state is going to experience a “tsunami” of these types of commercial installations in coming years.
“It just adds more generating capacity to an already oversupplied system, but it is something we have to cope with,” Mr Nahan said. “Over the next decade these are going to crowd out traditional, large-scale generation of coal and gas. “As we go down the track, these technologies on businesses and households illustrates that into the future we are going to have to reduce our production of traditional energy sources and that’s the challenge.”
Victorian town Newstead set for 100% renewable energy within 5 years
PowerCor’s Thomson says it is clear that the majority of the population in Newstead are passionate
about their goal for 100% renewables, and at least five other townships are looking to follow suit.
Newstead could be the host of Victoria’s first solar-powered micro-grid.
The Victorian government is also heavily involved, allocating $200,000 in the hope that the model created for Newstead can be replicable in other communities across Victoria.
Australian first: Newstead aims to run on 100% renewable energy within five years, http://www.theguardian.com/sustainable-business/2016/mar/01/australian-first-newstead-aims-to-run-on-100-renewable-energy-within-five-years Guardian, Giles Parkinson, 1 Mar 16
Agreement with energy company Powercor will see Victorian town move to solar power, save money and perhaps become a model for other towns. The quiet Victorian town of Newstead – population approaching 500 – has a big ambition: to source all its electricity needs without burning any fossil fuels at all. Within five years, it wants all of its power to come from renewable energy sources.
Newstead is not unique in that goal. At least a dozen towns around Australia, including Yackandandah, Tyalgum, Byron Bay and Lismore, have declared a similar ambition, even if most are allowing themselves more time to reach the target.
What makes Newstead’s situation particularly interesting is it is going ahead with the support, indeed the encouragement, of its local network provider, Powercor.
An agreement struck between the network and Newstead 2021 – the local group driving the township’s ambition – is being hailed as a “game-changer” for the way communities and network operators work together to accelerate the transition to renewable energy.
Glen Thomson, the head of the energy solutions division of Powercor, says renewable generation is now a reality, and solar, wind power and energy storage are increasingly being integrated into electricity networks. Continue reading
Sapphire Wind Farm to bring huge benefits to Australian Capital Territory’s economy
Latest wind auction winner promises millions in benefits to Canberra economy, SMH March 4, 2016 – Tom McIlroy Legislative Assembly reporter at The Canberra Times The fifth and final winner of the ACT government’s large-scale wind reverse-auction will provide enough power for more than 48,000 Canberra homes.
Environment and Climate Change Minister Simon Corbell has announced Sapphire Wind Farm, 18 kilometres west of Glenn Innes in north-eastern New South Wales, as the latest successful proponent from the government’s second wind auction, promising an estimated $100 million dollars in economic benefits to the ACT
Sapphire has been awarded a feed-in-tariff of $89.10 per mW/h for 100mW capacity. The company will spend $34 million on development of an ACT-based asset and operations management centre, relocating operations from Newcastle.
A spokesman for Mr Corbell said the consortium behind the bid included companies Continental Wind Partners and Wind Energy Holdings.
“By the time Sapphire starts producing energy in 2018, the ACT will be sourcing 80 per cent of its energy needs from renewable sources and well on the way to achieving 90 per cent by 2020,” Mr Corbell said.
In August last year, the government called for bids in its second wind auction to power up to 106,000 Canberra homes, seeking 200 megawatts in new capacity to come online within three years.
It follows two previous auctions: in 2013, three solar farms won 20-year feed-in deals, delivering 40 megawatts capacity, and in a wind auction earlier this year three wind farms won similar deals, delivering 200 megawatts among them.
CWP Renewables managing director Alex Hewitt said the auction result had allowed commencement of construction of what will be the largest wind farm in the NSW. http://www.smh.com.au/environment/energy-smart/latest-wind-auction-winner-promises-millions-in-benefits-to-canberra-economy-20160303-gn9n0a.html
Renewable energy micro-grid plannned for Kalbarri, Western Australia
Renewable energy micro-grid could help restore faith in Kalbarri power supply, ABC News, 3 Mar 16 By Bonnie Christian The WA Government has announced it will commit $300,000 to investigate a way to build an energy micro-grid powered by renewables for the coastal town of Kalbarri.
Kalbarri has experienced several extended power outages over the past two years, costing local businesses thousands of dollars in lost trade and tourism.
The outages had been blamed on a build up of dust and salt on the 140-kilometre-long feeder line that delivers power to the town from Geraldton………..
Rebuilding trust in power supply
Western Power chief executive Paul Italiano said if the new grid did go ahead it would be the largest of its kind in Australia.
“What we’re proposing to do here is evaluating the feasibility of building a micro-grid in Kalbarri that has a combination of solar, perhaps wind, and large scale battery storage that work together to create a level of self-sufficiency for the town,” he said.
“This particular trial — if we’re able to pull it off — will be the largest in Australia.
“There’ll be lessons from this that we can apply to the rest of Western Australia. But more importantly for the whole power industry nationally.”…….http://www.abc.net.au/news/2016-03-02/kalbarri-looks-to-renewable-energy-micro-grid-for-power-solution/7215630

Solar energy to the grid: New South Wales’ Moree solar farm in operation
Moree solar farm starts feeding energy into grid http://www.abc.net.au/news/2016-02-29/moree-solar-farm-starts-feeding-the-grid/7207942 ABC New England By Kelly Fuller The largest single-axis tracking solar farm in the country is now feeding energy back into the grid from Moree in New South Wales.
The solar farm is led by Fotowatio Renewable Ventures (FRV) and has been funded with assistance of a $102 million grant from Australian Renewable Energy Agency and $47 million in debt financing from the Clean Energy Finance Corporation.
At full capacity the project is expected to generate 140,000 megawatt hours per annum, or the equivalent energy to supply the needs of 15,000 homes.
The company’s country manager Cameron Gamsworthy said feeding energy back into the grid was a significant step in the project’s development.
“It’s absolutely a major milestone. We’re now generating clean, renewable energy for the country,” he said. “[We are] looking forward to getting the project fully commissioned over the course of the next month.”
The farm’s 222,000 panels are expected to have a life of 30 years, and the company hopes the project will be at full capacity in a month’s time.
Mr Gamsworthy said FRV was considering other projects in the region.
Farm solar is the future
While the Moree project is unique, a University of New England academic said there was a growing demand for solar energy, particularly among rural communities.
“Farmers are getting more and more hungry for mobile technology that can be distributed around the farm,” said Professor David Lamb, from the university’s Smart Farm. “It could be a little water bore pump or some sort of gate alarm system or a trough monitor,” he said. “All of these technologies are going to need solar themselves because we obviously don’t want powerlines running around farms.
“I wouldn’t be surprised if there are literally thousands of little solar panels balancing on the back seat of old tractors that are used to keep the battery alive while it is left out in the weather for the next start.”At the end of the day the solar panel is becoming the set of pliers on a farm — you see them everywhere you look.”
Professor Lamb said the university was putting up ‘smart trees’ around the Smart Farm. “We literally have little sensors in the trees showing the amount of water these guys suck out of the ground, and each and every one of these trees has their own solar panel,” he said.
“[It] is quite ironic when you consider that trees are one of the most efficient harvesters of solar energy that we know.”
Tasmania’s great opportunities in renewable energy
King Island is emblematic of the challenges and opportunities facing the state. It is blessed with natural resources, but punished by its relative remoteness and lack of economies of scale. It has been a perfect testing ground for renewable technology, and has led to the Hydro exporting novel approaches to overseas markets. The project has already avoided the use of 18 million litres of diesel, and saved more than $24 million.
Tassie must look to future in renewables, February 29, 2016, ROSALIE WOODRUFF, Mercury “……… The Paris climate agreement sends a clear message to governments and investors that the age of fossil fuels is finished. There is a momentum around renewable energy generation, pushed by an urgency to respond to global warming and an explosion of new technology.
From crisis comes opportunity. The Greens are focused on the long-term task of transitioning Australia away from dependence on fossil fuels. The future is clearly in renewable energy generation, for pragmatism and prosperity.
We have released the Greens Energy Strategy, a blueprint for how the state can get started immediately on setting the business conditions we need to attract medium to large-scale renewable projects.
Our target is for Tasmania to be self-sufficient in clean electricity generation by 2022, and to be net exporters to the mainland. This is achievable. Continue reading
AGL proceeding with Silverton wind farm project in far west NSW
AGL vows to go ahead with Silverton wind farm project in far west NSW ABC Broken Hill
By Declan Gooch 27 Feb 16 Energy company AGL has reaffirmed its commitment to the Silverton wind farm project in far west New South Wales, and says studies of the site will get under way within weeks.
The proposed site along the Barrier Ranges just outside the Silverton township was first proposed in 2007 by Epuron, but stalled after AGL took over in 2012. AGL blamed uncertainty about the federal government’s Renewable Energy Target for the pause, with development approval set to run out in May.
The company announced at a community meeting on Thursday night it applied that day to have another five years added to the approval, and announced a new project manager, Adam Mackett.”We’re already doing work through the hydrogeological study where we’re committed to this project, so we’re showing that,” Mr Mackett said. “It is a half-a-billion-dollar project so before we then fully commit to constructing it we need to do a bit of work.”
Mr Mackett is no stranger to the state’s far west, having managed the construction of the Broken Hill solar farm around 25 minutes away. He also oversaw the construction of South Australia’s Hallett wind farm.
“We’re confident of having [the Silverton project] extended, we think the Silverton wind farm is a fantastic opportunity.”
AGL hopes the wind farm will generate enough power to supply around 120,000 average homes.
Funding will be contributed from AGL’s newly-announced Powering Australian Renewables Fund, which will be seeded partly by the Broken Hill solar farm……… AGL said it hopes its Powering Australian Renewables fund will be set up by the middle of the year, and that the extension to the project’s approval will be signed off in the next three months. http://www.abc.net.au/news/2016-02-26/agl-vows-to-go-ahead-with-silverton-wind-farm-project/7202338
Australia at risk of missing its 2020 renewable energy target
Some continue to blame the sluggish investment on the uncertainty created by then Prime Minister Tony Abbott’s ferocious push across 2014 and 2015 to cut the renewable energy target. Last year the government and Labor struck a deal to lower the target.
In recent times there have been some positive signs of movement.. This month energy giant AGL launched an investment fund aimed at delivering 1000 megawatts worth of renewable energy, while Origin Energy head Grant King was quoted saying his company was preparing to back new projects………
Australia risks missing clean power goals, with households to pick up the bill, SMH, February 28, 2016 Tom Arup Environment editor, The Age Australia risks not hitting its 2020 renewable energy target with analysts now forecasting that interim goals will be missed – a situation that will trigger penalties that households will have to pay.
Many in the energy industry agree that this year will be “make or break” for achieving the end-of-decade target, which aims to deliver about 23 per cent of Australia’s electricity from clean technologies such as wind and solar.
“This year is critical” said Kane Thornton, who heads the Clean Energy Council……….. Continue reading
Gas company APA joins throng to spend on renewable energy projects
APA aims to ramp up renewable energy spending, The Age February 28, 2016 Brian Robins APA wants a seat at the table in the multibillion-dollar investment boom in renewable energy sources over the next few years amid national moves to meet the mandated renewable energy target.
This month, AGL said it might launch a $3 billion fund to build renewable energy projects such as wind and solar farms.
Rival Origin Energy said it might invest in similar projects but would most likely buy the output under long-term contracts.
Under federal government policy, one-fifth of electricity must be sourced from renewable energy by 2020. The move is expected to hasten the closure of heavily polluting coal-fired power stations…….
APA is considering several projects, including a potential solar farm in Western Australia, if it wins support from Australian Renewable Energy Agency funding and signs a power sales agreement. It is also bidding on an estimated 90MW of wind turbine capacity in the Northern Territory………http://www.theage.com.au/business/apa-aims-to-ramp-up-renewable-energy-spending-20160224-gn2a1g.html
Melbourne Girls’ College’s original approach to becoming carbon neutral
Melbourne Girls’ College pedals toward carbon neutral status with outdoor cinema, solar installations, ABC News, 19 Feb 16 774 ABC Melbourne By Clare Rawlinson An all-girls Melbourne high school is on its way to becoming the first Victorian school to go carbon neutral.
Melbourne Girls’ College is working towards carbon neutral status through the installation of solar arrays and energy reduction projects, spearheaded by the school’s Sustainability Collective.
The passionate young environmentalists are hosting an outdoor cinema powered by bicycles and ergo machines on Friday, to share their quest with the public and draw attention to the true cost of energy.
The students will pedal all day to charge the cinema batteries for the screening of movie Oddball, as well as the power for coffee carts and popcorn machines.
“The idea behind it is to show people what a watt hour is and how much electricity goes into these events,” former student Ruby Wynn Williams said.
Sustainability coordinator Andrew Vance said the first step towards the school’s goal of carbon neutrality was awareness. “It’s really easy to burn some coal to watch a movie but it’s completely out of sight and out of mind,” he said. “When you get on the bike and pedal two watts, it’s like an epiphany.”
Reputation for environmental sustainability
The school’s reputation for environmental sustainability has already earned it acclaim through a major international competition, the Zayed Future Energy Prize. In 2015 it was selected as one of five schools globally to receive the competition’s $US100,000 funding grant for sustainability projects.
The majority of the prize money has been spent on converting the school’s permanent power source to solar, with the installation of a 33kW solar array on one side of the gymnasium roof.
It plans to cover the other side of the roof with community-funded solar arrays.
“[Each person] who buys a panel will get their name on it … so they can go and look at how much carbon they’ve offset and the equivalent in trees,” Mr Vance said.
“That will get us close to our carbon neutral goal.”…….http://www.abc.net.au/news/2016-02-19/melbourne-girls-college-pedals-toward-carbon-neutrality/7180684
