Portugal’s water agency, Instituto da Agua, seeks proposals for construction of four hydroelectric projects on the Alto Tamega River totaling 424 MW. Bids are due June 30.
In announcing the solicitation April 1, Prime Minister Jose Socrates said the four dams are expected to cost between 450 million and 760 million euros (US$700 million and US$1.18 billion). Construction of the new dams is expected to start in 2010.
Projects offered include 112-MW Gouvaes, 113-MW Padroselos, 90-MW Alto Tamega, and 109-MW Daivoes.
The projects are among ten new projects, and five hydro project expansions, included in Portugal’s national program of dams with high hydropower potential, Programa Nacional de Barragens com Elevado Potencial Hidroelectrico. (HNN 10/8/07) The other new projects are 163-MW Fridao, 78-MW Almourol, 77-MW Pinhosao, 72-MW Girabolhos, 48-MW Alvito, and 234-MW Foz Tua.
Energias de Portugal (EDP), the sole bidder for an earlier concession to develop Foz Tua, said April 1 it was awarded a preliminary concession to develop the project on the Tua River and operate it for 75 years. EDP said it is to pay 53.1 million euros (US$82.5 million) for the concession.
The five hydro project expansions in the national program are 248-MW Picote 2 (HNN 11/14/07), 191-MW Bemposta 2 (HNN 3/19/08), 240-MW Alqueva 2 (HNN 3/6/08), 170-MW Baixo Sabor (HNN 3/20/08), and 70-MW Ribeiradio (HNN 2/7/08).
