Peru opens bidding for part of 530-MW Majes-Siguas 2 complex

Peru’s investment agency, ProInversion, seeks bids by August 31 for construction of a portion of the 530-MW Majes-Siguas 2 irrigation and hydroelectric complex.

Majes-Siguas 2 has three components, construction of Angostura Dam and a 16-kilometer water tunnel, irrigation infrastructure to supply 42,000 hectares, and construction of the 98-MW Tarucani, 116-MW Lluta, and 316-MW Lluclla hydroelectric plants on the Siguas River.

ProInversion said two Peruvian and three foreign companies had bought rights to participate in the concession auction. The successful bidder is to build Angostura Dam, the TrasAndino Tunnel, and the water distribution and irrigation network for 42,000 hectares.

Peru has approved US$120 million in co-financing for construction of Angostura Dam. Private investors are to supply the remainder of the US$280 million investment in the dam, near the confluence of the Hornillos and Apurimac rivers. The power plants reportedly are to require a US$500 million investment.

Qualified bidders are to be announced September 11. They are to submit technical and economic offers October 23. A winning bidder is to be announced November 10.
