Russian aluminium producer RusAI says that it will invest US$600-650M in the construction of the Rogun hydroelectric power plant in Tajikistan, according to the Interfax news agency.

RusAl is building the plant in co-operation with the Tajik government. The precise level of investment will be known after a feasibility study is completed by Germany’s Lahmeyer in early October 2005.

A RusAl official said that the company is considering participating in hydroelectric power projects in other countries in the Commonwealth of Independent States.
