Australia’s wineries go green using solar energy

Australia’s wineries go green using solar energy

More Australian wineries are turning to the sun, making the switch to solar power to help in wine production. Driven by rising costs of electricity from non-renewable sources, lower costs of solar power installation, and the potential benefits of producing own power, many wineries haven taken the bold step of investing in more renewable sources. By utilising solar energy for growing grapes and producing wines, wineries in Australia can both save on major costs and reduce their overall carbon footprint.

Electricity is the biggest expense in wine production

For most wineries in Australia, electricity is their largest expense item in the production of their wines. The Australian Energy Market Operator (AEMO) estimates that around 40% of expenditures of wineries go towards electricity, whilst the South Australian Wine Industry Association (SAWIA) says that refrigeration eats up 50-70% of total power costs. Thus, it is no surprise that vineyards look for ways to reduce energy expenses.

Investing in renewable sources makes sense that will drive electricity expenditures down, lower overhead costs, and improve margins. For producers of quality Australian red wines, solar power not only reduces energy costs, but also maximises commercial roof space and reaffirms their commitment to a lower carbon footprint.

Incentive to attract investments in solar power

Solar power adoption surged in Australia in 2008, and even though costs of materials and installation were high, government incentives were also widely available until 2011. Between 2011-14, the prices of solar systems fell. From 2014 to present, there is relative stability in the solar system industry. Photovoltaic (PV) system prices are down significantly and there are existing incentive schemes for solar panels and batteries that are offered at state level, making investments in the area still attractive.

For 2020, interest-free loans up to $9,000 for a solar battery and $14,000 for a solar PV and battery storage system for households with an annual income of $180,000 or less are available. Under the Small-Scale Renewable Energy Scheme, both households and smalls business in Australia that install small-scale renewable energy systems may be eligible for assistance to help with the purchase cost. Eligible participants may be entitled to small-scale technology certificates which can be sold to recoup a part of the purchase and installation cost.

Wineries adopt renewable power sources

An independent report produced by AgEconPlus revealed a 13% increase in the economic contribution of the wine industry since 2015 or an increase of roughly 3% per year. Strong wine exports are largely responsible for recovery in the wine sector. But, the competition is tough and the over 2,000 wineries in Australia have to stay competitive.

In fact, wineries were some of the earliest adopters of solar energy, with dozens in South Australia harnessing solar energy for wine production. Some wineries that have in excess of 100kW solar systems include D’Arenberg, Wirra Wirra, Sidewood, and Peter Lehmann. Recently, Pernod Ricard has become the first large wine company in the country to achieve 100% renewable electricity with the completion of Australia’s biggest combined winery solar installation. According to the winery’s chief operations officer, Brett McKinnon, “being sustainable and responsible is an important part of their business and they want to reduce their impact on the communities where they operate”.

Australian wineries recognise the opportunities to tap into solar energy and enjoy the cost-saving and environmental benefits. Using renewable sources not only lowers electricity costs, but also fulfils a company’s global-minded goals.

Sundrop Farms | Solar Greenhouse

Sundrop Farms have a solar greenhouse at Port Augusta in South Australia and today we’ll take a look at how it works and how effective the system is. 

Sundrop Farms | Solar Greenhouse

Sundrop Farms’ pilot facility was opened in Port Augusta in 2010. The solar hydroponic farming concept cost $200m to build and was opened at the end of 2016. It includes a 20 hectare solar greenhouse, a field of 23,000 mirrors, a 127m tall solar tower and a desalination plant. Another great step in the right direction for solar technology

According to an interview with Sundrop Farms Australia Managing Director Steve Marafiote in GQ, it was an easy choice to work with the company once he saw what their value proposition was:

“When I understood what Sundrop was about, I knew I wanted to be part of the business,” Mr. Marafiote said.

“This large-scale sustainable operation is world leading,” he continued. 

“If you look at the agricultural land where the farm is now, it was 120 hectare site that would traditionally sustain six to 10 cows a year. That’s it. Instead, that desert land has been converted to produce 15,000 tonnes of tomatoes a year – it’s a stark difference.”

The project had $100m of investment from private equity firm KKR and partners with Coles Supermarkets as an official partner. Sundrop has a 10 year contract with them to deliver truss tomatoes – giving them a sizeable 15% share of the Australian market. 

Another massive boon for companies wanting to use a method like this for renewable farming is that there is a surfeit of data points with which to make decisions, includeing monitoring and controlling such factors as water, fuel, temperature and electricity use:

“We know what those operating costs will look like for the next 20 years, and I don’t think there are too many sectors who have the luxury of that position.” said Marafiote.

SolarReserve sign MOU for Aurora Project

American company SolarReserve have signed an MoU with Heliostat SA to manufacture and assemble the components for their solar tower and molten salt storage facility at Port Augusta.

SolarReserve Commence Construction on Aurora Solar Thermal Plant

SolarReserve announced on Tuesday that they’ll work with Heliostat SA to create 12,800 96 square metre glass mirrors for their Aurora Solar Thermal Plant. 

The solar thermal plant in Port Augusta, South Australia, was announced last August and received developmental approval back in January It is slated to be a $750m project but we haven’t heard any specifics as to updated pricing, and this information is the first news on the project since January of this year. 

According to the CEO of SolarReserve, Kevin Smith, the solar thermal power plant will comprise of approximately 12,000 mirrors, each the size of a billboard (around 100sqm), arranged in a circle over 600 hectares. The mirrors will focus light and heat to the top of a 227m tall tower to generate up to 150MW. This will result in over a million square metres of surface area for the project. 

“Aurora will provide much needed capacity and firm energy delivery into the South Australian market to reduce price volatility,” Mr. Smith said at the time. He elaborated today when discussing the deal with Heliostat SA: 

“We’re excited to have formed a long-term partnership with Heliostat SA and look forward to teaming up with them to bring manufacturing of our world-class heliostats to South Australian workers,” said Mr. Smith.

“SolarReserve is committed to supporting South Australia’s goals which will attract investment, create South Australian jobs and build an exciting and growing new industry.”

According to an article on RenewEconomy the project will create around 200 full time solar jobs for the area, with 650 to be employed during the construction phase. 

This project is a bit slow and new information is thin on the ground, so great to hear that it’s moving ahead. We’ll keep you posted as soon as there’s any new information on the solar thermal plant!

Solar and Wind Farms in the Sahara Desert

New research in Science magazine shows that installing solar and wind farms in the Sahara Desert could generate massive amounts of electricity and turn parts of the desert green for the first time in over 4,500 years. 

Solar and Wind Farms in the Sahara Desert

Atmospheric scientist at the University of Maryland, Eugenia Kalnay, has been working on this theory for over ten years, postulating that the darkness of solar panels won’t reflect the sunlight – helping heat up the surface of the land – which will in turn drive air upwards into the atmosphere (which, in turn, generates rain). 

Dr. Kalnay talked one of her post-doc researchers into creating a computer simulation where 20% of the Sahara is covered with solar panels. They also tried a simulation where the desert was covered in turbines to generate renewable energy from wind. The simulation was successful – with rainfall in the desert increasing by a large enough amount so that vegetation could return to the Sahara.

“It is wonderful!” Dr. Kalnay was quoted as saying in an article by NPR. “We were so happy because it seems like a major solution for some of the problems that we have.”

The Sahara Desert solar farm in the simulation is gigantic – bigger than the entire continental United States. It’d be able to generate 400% of the energy the world currently requires. Would there be a way to install high-capacity transmission lines to transport this power across seas and land? It’s certainly a fantastic concept that seems straight out of a science fiction novel, but technology is increasing at such a pace that ideas like this are, whilst admittedly still in nascent stages, potentially viable. 

Take a look at our articles on printable solar panels/cells to see how, if room wasn’t an issue, how much cheaper large-scale solar could be with lower efficiency panels. 

More great information for solar cell technology. Just a thought experiment at this point but it’s exciting to see what the future could hold for renewable energy in the Sahara Desert!

Pilbara Solar Farm | Alinta Planning Off Grid Solar Farm

Alinta Energy have applied to the Western Australia Department of Water and Resources to clear 160 hectares at the proposed site of its Pilbara solar farm.

The planning application send through to the department is for permission to clear the 160 hectares of the site and also lays out a planning application for the Pilbara solar farm. 

“The clearing will be required so that Alinta Energy Transmission (Chichester) Pty Ltd (Alinta) can build, own and operate a solar field located adjacent to Fortescue Metals Group’s (FMG’s) Christmas Creek Substation in the Pilbara region of Western Australia (the Project),” the application says, according to RenewEconomy, who have quoted ‘solar industry insiders’ who estimate the size of the solar farm to be around 60MW (Alinta haven’t announced the size of the proposed farm yet).  

“The Project will supply FMG’s Christmas Creek mine site with power to support ongoing mining operations” the report continues.

It’s understood that the project will probably use single axis tracking and hopefully usurp the current energy for the Christmas Creek mine – an expensive and ecologically unfriendly 58MW diesel plant. This goes to show how important renewable energy in resources is – especially when you’re dealing with a site far from the grid. Some of these mines use an astronomical amount of power and having as much as possible of that power requirement coming from renewable energy is a fantastic step in the right direction for the resources industry in Australia. 

Last month Alinta made a development application for the 65km energy transmission line which would link the Christmas Creek mine with the Cloudbreak mine – so this gives us a bit of an idea as to what they are hoping to achieve in the future. Don’t be surprised if you hear more about this solar farm and a whopping great battery to go with it! Watch this space.
