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 405 megawatts peak power (MWp) – 317.5 MW rated capacity – the photovoltaic plant is one of the highest capacity in Mexico and Latin America and the biggest renewables project ever undertaken by ACCIONA in the world owned by the company.
Of the total capacity of the photovoltaic plant, 229 MWp (180 MW nominal) will be used to supply energy to the Federal Electricity Commission (CFE), following the award won in the second long-term energy auction held in September 2016.
Another 114 MWp (90 MW nominal) comes under a private energy purchase and sale contract between the consortium that owns the project and the company Tuto Energy Trading. This capacity will be sent to the installations of a major Mexican industrial group.
Finally, the energy produced by the remaining 61 MWp (47.5 MW nominal) will be sold on the wholesale electricity market following the extension of the scope of the project, with a view to optimizing its generation capacity in an area with an excellent solar resource.
Puerto Libertad covers almost 10 km2 in the municipality of the same name near the Mar de Cortés coast in the Gulf of Baja California, around 200 kilometers north-west of Hermosillo, capital of the State of Sonora.
The facility, among the biggest photovoltaic plants in Latin America, is equipped with 1,222,800 polycrystalline silicon panels mounted on horizontal tracker systems. These are programmed to track the sun’s path across the sky from dawn to dusk. Placed in a straight line, the structures (20,380 units, each one 59.46 meters long) would cover a distance of 1,212 kilometers, similar to the distance between Mexico City and Houston.
With a total solar capture area of 2.4 km2 (equivalent to 333 soccer fields), Puerto Libertad will produce around 963 gigawatt-hours (GWh) of power per year, sufficient to cover the electricity demand of 583,000 Mexican homes. As it is renewable, this energy will avoid the emission of 925,443 tonnes of CO2 to the atmosphere from coal-fired power stations, representing a cleaning effect on the atmosphere of more than 46 million trees.
ACCIONA carried out the turnkey construction of the plant in the Engineering, Procurement and Construction (EPC) modality. It will also undertake its operation and maintenance for two years, after which time this function will be taken over by a joint venture set up by the two partners in the project.
During the construction phase an average of 500 direct jobs were created, with activity peaks of up to 900 workers. In the operational phase, the plant will provide stable employment for 38 people.

Technology and innovation
We provide our customers with real-time traceability of energy from our renewable generation plants and storage systems to their points of consumption. This information is not only integrated in an interface that our customers 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. The I'MNOVATION Startups program was the umbrella under which the first pilot for this solution was developed.
The activities carried out in the construction of the photovoltaic plant in Puerto Libertad (Mexico) apply the lean manufacturing methodology for the optimization of the construction phase of large photovoltaic installations.
The goal is to reduce costs and timescales in the construction of photovoltaic power plants, as well as to minimize the risks and variability of processes and designs without compromising the quality and safety of these renewable facilities.
In 2018, the cost reduction has been possible thanks to a significant reduction in man-hours in the execution, as a result of contracting with this logistics model, as well as in the man-hours of machinery.
The process improvements implemented enable ACCIONA to tackle the photovoltaic plant construction project with a significantly optimized execution time.
Puerto Libertad Photovoltaic Plant
How a large-scale photovoltaic plant is built in record time
A solar-panel complex was completed a few months ago in the Sonoran Desert in Mexico. From a bird's-eye view, the Puerto Libertad photovoltaic plant looks like a large glass lake. Together, the panels are able to generate clean energy
