The company generates clean energy in many technologies including; wind, solar PV, solar thermal, hydro and biomass. ACCIONA Energía is the largest 100% clean energy company in the world and leader in the global ranking of Energy Intelligence's Top 100 Green Utilities since 2015.
The company offers reliable and efficient solutions based on the most advanced technologies in the field of green energy infrastructure. This also includes the sale of electricity from 100% renewable origin in the electricity markets and through bilateral contracts with large customers, with special focus on corporations that want to reduce their carbon footprint.
ACCIONA Energía has developed its own wind turbine-generator technology, which capped its success by agreeing to merge with the German company Nordex in 2016, creating a global leader in turbine manufacturing. In parallel, ACCIONA Energía became the biggest shareholder in Nordex, thus maintaining its presence throughout the wind energy value chain.
When it comes to renewable energy infrastructure in Australia, the company has made significant investments in wind energy in particular. ACCIONA Energía in Australia has a total installed wind capacity of 600 MW and is currently constructing a 1GW wind farm in Queensland, which will be the largest in the southern hemisphere.
Our green energy infrastructure projects are helping to transition Australia to a low carbon economy, whilst providing future job growth and economic benefit to the communities where we operate. These projects also contribute to Australia meeting renewable energy targets and SDG 7: access to affordable and clean energy.
Sustainability is a core principle at ACCIONA. We are fully committed to delivering optimal energy solutions that contribute to decarbonising the economy and fostering a positive environmental impact, ensuring sustainable development. Our Sustainability Report highlights our key initiatives in this realm, solidifying our position as a leader in sustainability.
Over the past twenty years, ACCIONA has evolved with determination, driven by a pioneering spirit that has enabled us to anticipate the major challenges we have faced. Step by step, we have built a business model focused on delivering sustainable and technically advanced solutions to global challenges such as climate change, water scarcity, and rapid urbanisation.
ACCIONA Energía develops, builds, owns and operates renewable energy infrastructure across three areas: energy generation, energy storage and energy transmission. In Australia this means utility-scale wind and solar farms, battery energy storage systems (BESS), and the transmission infrastructure that connects clean generation to the grid.
We are the largest 100% clean energy company in the world and have led Energy Intelligence's Top 100 Green Utilities ranking since 2015. Globally we generate electricity from wind, solar PV, solar thermal, hydro and biomass. In Australia, we have been developing wind energy since 2002 and operate 600 MW of installed wind capacity, with the 923 MW MacIntyre Wind Precinct and the 387 MW Aldoga Solar Farm, both in Queensland, now entering service.
What distinguishes our model is that we are an owner-operator, not a contractor alone. We take projects from development and financing through construction and commissioning, and then operate them for decades — which means we carry the long-term performance risk of everything we build.
Wind energy produces zero carbon emissions during operation. Unlike coal, gas or oil-fired power stations, wind turbines generate electricity without burning fuel, releasing no CO2, nitrogen oxides, or particulate matter into the atmosphere. This makes wind one of the cleanest energy sources available at scale — and a critical tool in addressing climate change.
Beyond eliminating direct emissions, wind farms have a minimal land footprint. At ACCIONA's MacIntyre Wind Precinct in Queensland, the turbines coexist with working farmland — host farmers continue grazing livestock and growing crops across the same 32,000-hectare site. This dual land use model means wind energy does not displace food production or require clearing of native habitat, unlike some other large-scale energy developments.
ACCIONA Energía also invests in biodiversity monitoring programs across all operating wind farms. We use advanced bird and bat detection technology to monitor and manage any potential impact on local wildlife, and we embed environmental management plans into every project's operational phase. Our goal is not just to reduce harm, but to actively improve the ecological health of the landscapes where we operate.
Wind energy is electricity generated from the kinetic energy of moving air. As wind passes over a wind turbine's blades, their aerofoil shape causes them to rotate. That rotation drives a generator housed in the nacelle at the top of the tower, which converts mechanical energy into electrical energy.
The electricity produced by each turbine then travels through underground cabling to a substation within the wind farm, where the voltage is stepped up so the power can be carried long distances with minimal loss. From there it enters the transmission network and is distributed to homes, businesses and industry.
Wind is a renewable resource. It is generated continuously by the sun heating the earth's surface unevenly, which means — unlike coal, gas or oil — it cannot be depleted and requires no fuel to be extracted, transported or burned.
A single modern onshore wind turbine can supply electricity to several thousand homes. At ACCIONA Energía's MacIntyre Wind Precinct in Queensland, each 5.7 MW Nordex Delta 4000 turbine generates enough clean electricity to power approximately 4,300 Australian households a year.
Across the full precinct, 162 turbines with a combined capacity of 923 MW are projected to supply clean electricity to nearly 700,000 homes and avoid around 3 million tonnes of CO₂ emissions annually.
How many houses a wind turbine can power depends on three variables: the turbine's rated capacity, the strength and consistency of the wind resource at the site, and average household electricity consumption in that region. Turbine technology is also a factor. Machines installed 20 or 30 years ago typically had capacities below 1 MW and powered a few hundred homes each. Advances in blade design, materials and real-time wind monitoring mean a single turbine today produces several times more electricity from the same footprint.
Wind turbine output is measured in two different ways, and the distinction matters. Rated capacity is the maximum power a turbine can generate at any given moment — 5.7 MW for each Delta4000 turbine at MacIntyre. Annual generation is what it actually delivers across a year, which for a turbine of that size in a strong Australian wind resource is in the order of 20,000 MWh.
At precinct scale, MacIntyre's 162 turbines represent 923 MW of installed capacity, making it one of the largest onshore wind farms in the world. The precinct is already exporting up to 461 MW of clean energy to the grid during commissioning, and has the potential to expand toward 2,000 MW of total capacity.
For context, ACCIONA Energía's total installed wind capacity in Australia stands at 600 MW across our operating fleet, built up since we entered the Australian wind market in 2002
