    Tama te Ra'a photovoltaic plant

    ACCIONA Energy has installed the first renewable facility connected to the power grid in Easter Island (Chile). 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 in the middle of the Pacific towards a clean energy system. The installation, designed and built by ACCIONA, has been donated to the local electricity company as a contribution to the sustainable development of one of the landscaping and ethnographic gems of humanity.

     

     

    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.
