Portuguese energy company Efacec has installed the largest and most powerful transformer in Angola. The first of seven power transformers that equip the Laúca Hydroelectric Power Plant, this transformer has a power output of 371 MVA and voltage levels of 400/ 18 kV.

Portuguese companys wins African power projectsLocated between the provinces of Cuanza Norte and Malanje, the Laúca Hydroelectric Plant, whose construction started in 2012, is the third dam under construction in the Kwanza river bed, after Cambambe and Capanda, and will have a production capacity of 2070 megawatts. The transformer will be used for the energy produced by the first generating set of the dam, benefiting more than eight million people.

This power transformer, a split-phase solution, was produced at Efacec's plant in Arroteia, Portugal, for Andritz Hydro. Each of the transformer's phases was shipped separately to allow the successful transport of the large equipment to places hard to reach by road. Efacec's local team ensured the assembly, filling, testing and start-up assistance operations were done correctly.

The Angolan project comes shortly after Efacec won the international tender to implement the engineering, supply, supervision and commissioning of the three new substations in Rwanda on a turn-key basis. This contract was worth approximately €10.5 million.

Currently only 25% of Rwanda’s households have power. This project is part of the government’s ambition to bring electrical energy to 70% of Rwanda’s families by 2018. The substations are to distribute power to the country’s rural areas, such as Mamba Sector, Gisagara District, Rwabusoro in Nyanza district and Rilima in Bugesera district. In 2010, Tunisian electricity and gas company International Services (STEG) signed a $68.6 million deal with Rwanda to connect 50 000 households to the national electric grid.

“Being chosen for this project attests, once again, to Efacec’s skills. We are proud of this new act of trust bestowed to our company. We’ll continuously work in order to bring power to all the parts of the world,” says Ângelo Ramalho, Efacec’s CEO.
