CLEAN, NON-POLLUTING ENERGY
Ensure access to affordable, reliable, sustainable and modern energy for all
1 in 8 people still do not have access to electricity. In order to ensure access to affordable, reliable, sustainable and modern energy for all, it is necessary to increase the use of renewable energy from 25 % today to 38 % in 2025.
ACCIONA is positioning itself as a key player in addressing the growth in energy demand while curbing the progress of global warming and promoting the transition to a decarbonized energy model.
Take urgent action to combat climate change and its impacts
The generation and use of energy is responsible for 74 % of total greenhouse gas emissions in the world. This activity is the largest contributor to global warming. Investment in renewable energy, energy efficiency and other low carbon technologies will continue to be essential to meet the new needs of humanity and to minimise their negative impact on the environment.
ACCIONA considers the fight against climate change and its related effects to be a strategic priority. The Company is working to mitigate greenhouse gas emissions in order to contribute to the progress of society and respond to the main challenges of sustainable development in the areas of infrastructure, water and energy, leading the transition to a low-carbon economy.
With 246 MWp peak capacity, El Romero Solar produces energy equivalent to the consumption of around 240.000 Chilean homes. Eighty megawatt are used to power 100% the Google's data center in Chile.
Located in the municipality of Vallenar, in the Atacama Region, 645 km north of the capital Santiago, the new facility is able to generate 493 GWh of clean energy a year on average, avoiding the emission of around 474,000 metric tons to the atmosphere in coal-fired power stations.
The El Romero Solar plant covers 280 hectares in one of the driest places on the planet. It has a high level of solar radiation and very clean air, which facilitates the capture of the sun’s energy. These factors have been crucial in the installation of astronomical observatories in the area.
The plant is equipped with 776,000 polycrystalline silicon photovoltaic modules, making up a solar capture surface of over 1.5 million m2 (equivalent to 211 professional soccer pitches). The panels are installed on static metal structures which, if lined up, would have a total length of over 196 kilometers.

Technology and innovation
The GREENCHAIN® project was born with the purpose of providing our customers with real-time traceability of energy from our renewable generation plants and storage systems to their points of consumption. To this end, not only is this information integrated into an interface that our clients can use to visualize or download the data or display dynamically in their facilities as a marketing tool, but it is also recorded in blockchain to increase transparency. This software tool also integrates information on the social initiatives that ACCIONA carries out in the communities where its generation plants are located, with the aim of making our clients participants in the social commitment that characterizes ACCIONA.
The I'MNOVATION Startups program was the umbrella under which the first pilot for this solution was developed.
Hub el Romero Solar
ACCIONA has created a hub at its El Romero plant to test new photovoltaic technologies that can increase the efficiency and performance of solar installations, in particular the mechanical and energy performance of bifacial crystalline technology, split-cell and thin-film cadmium telluride (CdTe) modules, technologies that are expected to mark the future evolution of photovoltaic energy.
