Clean energy in the middle of the Pacific
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.
The Tama Te Ra'a photovoltaic plant (first rays of the sun in the Rapa Nui language) marks the beginning of the journey of this paradisiacal enclave, located in the middle of the Pacific, towards an energy system that is one hundred percent clean. The facility, designed and built by ACCIONA, was donated to the local electricity company as a contribution to the sustainable development of one of mankind's scenic and ethnographic jewels.
The solar plant will produce an annual average of around 200 MWh, avoiding the direct emission of 135 tonnes of CO2 per year in the process (not including the emissions produced by the transport of fossil fuel from the continent). This clean production will also avoid 8% of the consumption of diesel fuel for electricity generation, which has to be regularly brought by sea from the Chilean mainland.
The photovoltaic system consists of 400 polycrystalline silicon panels mounted on ten fixed structures, with a total peak capacity of 128 kWp (100 kW rated capacity). It is equipped with an inverter that converts the DC electricity generated into AC, a transformer that raises the output voltage from 0.42 kilovolts (kV) to 13.2 kV and a 100-meter-long line to transport the power to the Mataveri substation, where it is injected into the island's grid.
With a surface area of 163.6 km2 and well-known worldwide for its archeological remains (particularly the large stone statues called 'moái'), Easter Island's population is just over 5,000, and mainly concentrated in the capital, Hanga Roa. 40% of the island's territory is covered by the Rapa Nui National Park, declared a World Heritage Site by the United Nations in 1995.

Rapa Nui, the island where the future is in the Sun
No one knows for sure the origin of the civilization of Easter Island. This 160 km2 triangle of earth emerging from the middle of nowhere in the Pacific Ocean, between Chile and the Polynesian islands, continues to be a mystery...
