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.

Redflow – ZBM2 Microgrid in Tasmania for Hackett

Redflow CEO Simon Hackett has shifted his Tasmanian sheep and cattle farm to a new power source – a 100kW ground mounted solar microgrid using 27 Redflow ZBM2 batteries. Nice to see the bosses eating their own dog food. Let’s take a look at the project and what their future plans are for it.

Redflow – ZBM2 Microgrid in Tasmania for Hackett

Hackett, the owner of Redflow,  will use an initial deployment of 27 ZBM2 batteries, storing as much as 270 kilowatt-hours (kWh) of energy, interfaced to a large fault-tolerant cluster of 12 x Victron Quattro 48/15000 inverter/chargers.

“The project, with an overall budget of around $1 million, will include the building of a new site-wide microgrid. This will use new underground power interconnects to link seven distinct buildings across the whole property,” Hackett said in a statement. He went on to discuss the existing situation at the sheep and cattle farm he owns:

“We already have a Tesla Model S at the property and we plan to progressively replace our existing fleet of diesel farm ATVs, utes, and tractors with electric versions as soon they become available,” he said.

“We read with interest earlier this year that Toyota is committed to making electric HiLux 4WD vehicles and we would love to take delivery of the first of those to reach Australian shores.

Hackett explained that the Microgrid has myriad future plans and will be scalable:

“We can and will add more renewable energy generation using solar and/or wind if required in the future. Even after the full replacement of diesel vehicles with electric ones, we expect the property to be a net exporter of electrical energy to the Tasmanian grid,” he said.

Lastly, Hackett is very optimistic (mind you, he’d want to be) about the installation – we’re very interested to see some figures on how much it saves:

“I am convinced, based on my deep experience with Redflow, that ZBM2 batteries at the core of this energy system can deliver the hardworking energy storage and longevity to make this investment pay off over the long term,” he said in comments made last week.

Ballarat Energy Storage System | Solar Storage in Victoria

The Ballarat Energy Storage System has been turned on by the Victorian Government today – let’s take a look at this unique battery and see how it will help shape Victoria’s energy future!

Ballarat Energy Storage System

The Ballarat Energy Storage System has 30MW capacity and can output 30MWh – it’s located at the Ballarat terminal station and is owned by Australian energy company Ausnet. The battery storage units are Fluence branded, and were installed by Spotless and Downer Group.

ARENA and the Victorian Government will jointly provide $25 million in funding for both this project and the Gannawarra Energy Storage System (GESS). The project (BESS) is expected to end up costing around $35m. 

Lily D’Ambrosio, the minister for Energy, Environment and Climate Change, made a statement about the Ballarat Energy Storage System discussing the Government’s plans for Australia’s renewable energy future:

“We said we would deliver these large-scale batteries for Victoria, and that’s exactly what we’ve done,” she said.

“This is part of our plan to transition to a more affordable, reliable and clean energy system. We’re modernising our electricity grid, strengthening our energy security and delivering real action on climate change.”

According to RenewEconomy, the battery will be most useful in these three situations:

  1. It can help with congestion on Victoria’s transmission grid (especially as it’s installed at a network terminal rather than a wind or solar farm (which is the norm)). 
  2. It’ll help shore up the baseline load for Melbourne, especially during peak times when air conditioners and deconstructed latte machines are switched on en masse; and
  3. It’ll provide ‘key grid stability services’ like frequency control. 

Lastly, straight from the horses’s mouth:

The battery will store energy at times of relatively low value. The battery will use stored energy and use it at times of relatively high value. The project will also examine providing other grid services such as frequency control ancillary services (FCAS) and, should it be established under the electricity market rules, a Fast Frequency Response (FFR).

It’ll be fascinating to see how this works over the summer – we’ll, of course, also be keeping a close eye on the Tesla batteries at the Hornsdale Power Reserve to see if they’re able to continue delivering massive savings to the SA government. How long until the rest of the states follow suit?

The 24 month trial period means that customers participating will be able to ‘virtually’ store excess power they generate during the day (it’ll be fed into the utility-scale 105kW Tesla PowerPack Battery). They can then use 8kWhs of the PowerBank’s battery storage without needing to install their own power bank. According to the press release (and it’s true!), “8kWhs is enough to power the average suburban home for over one hour during peak time.”

Energy Minister Ben Wyatt discussed the Tesla PowerBank trial in a series of interesting quotes which explain how helpful this trial could be to Mandurah residents:

“PowerBank is an ‘in front of the meter’ storage trial which allows invited local customers to store excess electricity from already installed solar PV systems to then use it during peak times.

“This is another Australian milestone for the application of utility-scale batteries for the benefit for customers, drawing on the groundbreaking work by Synergy in its Alkimos Beach energy storage trial.

“For the first time in Australia, a utility-scale battery will be integrated into an established suburb’s network, like Meadow Springs, that has a high level of existing solar PV uptake.

“At the cost of one dollar a day, customers will have access to 8kWh of battery storage to use any time after 3pm each day.

“This trial shows that the WA Government is serious about working with renewables, delivering for taxpayers and planning for our energy future.”

Renovagen commercial-scale portable solar power

UK-based Renovagen has been doing some exciting work in the field of portable solar, with commercial-scale portable solar power systems utilising their ‘rapid roll’ technology recently deployed at Flat Holm, in the UK. They’re also working on rolling out (sorry) this technology on a much larger scale – their “Rapid Roll I” will fit in ISO shipping containers and could be a complete game changer in terms of commercial-scale portable solar power. 

Renovagen’s ‘Solar Carpet’ and Flat Holm

Flat Holm is a small island in the Bristol Channel, five miles off the south Wales coast. Traditionally, providing electricity for it has been a ‘challenge’, according to Flat Holm team leader Natalie Taylor. It has no mains supply and the island has been using old solar panels and diesel generators. 

Gareth Harcombe, energy and sustainability manager at Cardiff Council said: “We were looking at solar and hydro, but that takes up a lot of land and land in cities is expensive. But there is a lot of land that we have that’s available whilst it waits for other opportunities. So this was a question about how we could generate electricity in a way that was portable, so once the site is needed for something else it can be moved on.”

That’s where Renovagen came in – their “rapid roll” roll-up solar panels are providing an average of 11KW of power – enough for four residents and visits from tourists. The system includes batteries capable of storing 24KW/h of power, which is about a day’s worth of the island’s energy requirements. This is a fantastic and cost-effective interim solution until they decide what the optimal choice for Flat Holm’s electricity generation will be.

About Renovagen

John Hingley, Renovagen Managing Director, started work on this scaled-up mobile solar technology in 2012. It’s now the leading UK startup in commercial-scale portable solar power systems. They fully funded a £1,000,000 equity investment pitch via the UK crowdfunding platform, Crowdcube, in April last year – to help the speed up the development and go-to-market costs of their “Roll-Away” rapid roll portable solar systems. The company had hoped to raise £600,000 in equity funding so this was a great result. 

Currently based in Milton Keynes, their technology has been growing in leaps and bounds – take a look at the video below to learn more about how it works:

Rapid Roll Overview Video Presentation Sept 2016 from John Hingley on Vimeo.

Renovagen Rapid Roll “I”

The Renovagen Rapid Roll “I” is one of the most exciting of their products – currently under development, this portable solar power solution will come in an ISO (International Standards Organization or intermodal, i.e. a standardised size) shipping container and can provide enough power (depending on how technology goes, this could be up to 600kWp, according to Renovagen) for a small city. 

The idea of mobile and portable industrial size scale solar power one is extremely exciting and it has a lot of potential uses. The Rapid Roll “I” will fit in 20ft ISO or 40ft ISO containers and will be able to deploy 5x200m and 10x200m of solar panels respectively.

It comes complete with inverters and a large battery bank (specifics not available yet). 

Commercial-Scale Portable Solar Power

There are many uses for commercial-scale portable solar – off grid power in remote locations is extremely expensive and complicated to set up. Military, disaster relief, mining, construction, events, film production, and telecommunications are all situations where this ‘container solar’ idea could provide a huge help at a cost-effective price. 

If they’re able to scale this technology quickly, imagine how useful it’d be in situations like Puerto Rico where Hurricane Maria has left their ravaged state-owned utility PREPA trying frantically to restore power to the island’s 3.4 million residents. Elon Musk and Tesla has stepped in – they’ve been shipping their Powerpack and Powerwall batteries over there and there’s talk of installing a Tesla microgrid in Puerto Rico, but it’ll still be months before grid power is restored to anywhere but places that need it the most urgently (hospitals, authorities, etc.)

This is one of the biggest breakthroughs in portable solar of the past 10 years – so we’ll see what happens in the wake of Flat Holm and keep you updated. Very exciting stuff for solar!
