PORTUGAL – Efacec is completing the supply of transformers for the $1.7 billion (€1.5 billion) Tâmega Electroproduction System project for Iberdrola.

The project includes the manufacture and supply of transformers for the three plants that constitute the hydroelectric complex developed by Iberdrola in Alto Tâmega, Efacec said in a press release.

The commissioning for the Daivões hydroelectric power plant was concluded at the end of 2021, including in two 65 MVA 400 kV power transformers and two 2.5 MVA 15 kV distribution transformers.

To these was added the supply of four 245 MVA 410 kV power transformers for the Gouvães Hydroelectric Power Station and two 5.6 MVA 20 kV distribution transformers.

The last phase of the Tâmega Electrical Power System will be carried out until the end of May 2022 with the delivery of the last four transformers: two 90 MVA 410 kV power transformers and two 2.5 MVA 15 kV distribution transformers.

The hydroelectric complex integrated the construction of three dams (Daivões, Gouvães and Alto Tâmega), with an installed power of 1,158 MW, being able to reach an annual production of 1,760 GWh, assuring 6% of the national electric consumption.
