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.

CLIMATE ACTION

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.

Oaxaca II, III and IV represent one of the biggest wind power complexes in Latin America with 306 MW of operational capacity. They produce electricity to cover the consumption of 700,000 Mexican homes, avoiding the emission of 670,000 metric tons of CO2, equivalent to the cleaning effect of 33.5 million trees on the atmosphere through the process of photosynthesis.
ACCIONA is the leader in wind power in Mexico with 556.5 MW spread across four wind farms, the three mentioned above and Eurus (250.5 MW). The company has also built a 252MW wind power complex in Nuevo Leon and a 49,5MW wind farm in Oaxaca for third parties

GENERAL INFORMATION

  • Capacity:306 MW.
  • Start-up:2011.
  • Owner: ACCIONA.

WIND TURBINE

  • Wind turbine: ACCIONA Windpower AW70/1500.
  • Rotor diameter: 70 m
  • Wind class: IEC Ia
  • Tower: steel, hub height 80m.
  • Shovel: AW/Tecsis 34

KEY FIGURES

  • Installation of 204 wind turbines
  • Complex consisting of three wind farms (102 MW each - Oaxaca II, Oaxaca III and Oaxaca IV)
  • 34.5 km of access roads/tracks 
  • 350 km of underground cables  
  • 49 km power transmission line (230 kV)
  • Construction on sites with very low bearing capacity, so it was necessary to apply a range of solutions for the foundations, depending on the location
  • High wind speeds meant that the assembly had to be planned in very short periods to take advantage of low wind speed ‘windows’
  • The purchasing and logistics for the supply of materials such as concrete, steel, cables and other main components was directly managed by ACCIONA.
  • Wide-ranging program of socio-economic development in the local community.

Technology and innovation

GREENCHAIN®

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.

 

Turbine for life

Project that contributes to increasing the useful life of wind turbines, to knowing the state of the fleet and to detecting abnormal behaviour in order to optimise the management and the costs of operation and maintenance of the assets. For the analysis of the remaining life of the structural components, work is being done on developing physical models. To predict failures in Acciona's wind turbine fleet, work is being done along two lines: the development of WindBrain® to detect abnormal behaviour, and the use of Machine Learning to identify failure patterns in wind components.

ClimateTrade

We have increased the flexibility of CER (Certified Emission Reductions) sales processes by participating in a "Marketplace" called ClimateTrade, developed by the Valencian startup Climate Blockchain Initiatives, which puts CER generators such as ACCIONA in touch with polluting companies and other clients interested in offsetting their carbon footprint, greatly speeding up the procedures necessary for the sale of these certificates.

THOR®

By automatically detecting storms and generating warnings with the THOR tool, we increase the safety of our employees in ACCIONA's facilities and protect the state of the assets from electrical storms and their consequences.
