Prequalifiers in early November were invited by Tavanir to review the bid documents and will be asked to submit their final proposals in March.

International companies that have been prequalified include Italy’s Enelpower, Germany’s Dillinger Stahl (DSD), Japan’s Nichiman and Korea Electric Power Corporation (Kepco). The sole proposal submitted by a local company came from Iran Power Plant Projects Management Company (Mapna).

Prequalified companies will be eligible to bid for any or all of the six power stations. Tavanir had originally planned to build four power stations, but decided to split the Khoramabad and Zanjan plants into two separate entities.

Both Khoramabad 1 and 2 and Zanjan 1 and 2 will have capacity of 500 MW. Another two 500-MW plants will be located in Mashad and Kashan. The first stations to be tendered will be Zanjan 1 and 2.

The project is part of Tavanir’s programme to increase installed power capacity by 20,000 MW to more than 53,000 MW by 2012.
