Ecuador seeks design consultant for 228-MW Toachi-Pilaton

Development company Hidrotoapi S.A. seeks bids for a design consultant for the 228-MW Toachi-Pilaton hydroelectric project in Ecuador. Bids are due February 12.

Construtora Norberto Odebrecht had received a contract from Hidrotoapi S.A. to build Toachi-Pilaton. (HNN 3/7/08) However, Ecuador President Rafael Correa expelled the Brazilian builder from the country in a dispute over the 230-MW San Francisco hydroelectric project. (HNN 1/14/09)

Hidrotoapi, a company owned by Ecuador’s Pichincha Province, received a concession agreement for Toachi-Pilaton from Ecuador regulator Consejo Nacional de Electricidad.

Toachi-Pilaton involves construction of two hydropower plants, 50-MW Sarapullo on the Pilaton River and 178-MW Alluriquin on the Pilaton and Toachi rivers. Designed for the region’s rough volcanic terrain, the project is to feature 20 kilometers of tunnels, the largest being 8.5 kilometers long. A 12-kilometer 230-kilovolt transmission line also will be built.

In relaunching tendering for the project, Hidrotoapi sought only design engineering, with bidding for civil work and equipment expected later.

Tender documents may be obtained from the Hidrotoapi Internet site,, or from Ecuador’s bidding portal,

Two-part bids, containing technical and economic proposals in Spanish, are due by 4 p.m. February 12. Technical proposals will be opened February 12, followed by economic proposals March 4.
