Nepal renews call for geologic survey consultants for 140-MW Tanahu hydro project

Nepal hydro developer Tanahu Hydropower Ltd. has renewed a call for expressions of interest from geologic survey consultants to perform rock mechanical testing for the 140-MW Tanahu hydroelectric project on Nepal’s Seti River. Responses now are due November 1.

Tanahu Hydropower previously called for responses by September 11. It recruited consultants in August to provide hydropower construction supervision for Tanahu.

Tanahu (or Tanahun) originally was called the Upper Seti project, an estimated 127-MW plant that was among 10,000 MW of hydropower projects established as a priority over ten years by Nepal. Recently the project received a US$72.3 million loan from the European Investment Bank, a US$157 million loan from the government of Japan, US$30 million from the Abu Dhabi Fund for Development, and US$150 million each from the Asian Development Bank (ADB) and Japan International Cooperation Agency.

The project is to include a 140-MW hydropower plant with significant water storage facilities, a sediment flushing system, and transmission lines; rural electrification and community development; and a reform and restructuring plan for the Nepal Electricity Authority.

Tanahu Hydropower Ltd. now seeks a team of rock mechanical test specialists and geologists for preparation of a detailed rock mechanical test plan, testing and analysis, and reporting to the developer. Geological investigations are being performed to help bidders precisely estimate the geological risks when preparing their bids. With a budget of US$1.9 million, the work is expected to require 12 months.

A solicitation notice, including terms of reference, may be obtained from the ADB Internet site,, under the links “Businesses,” “Consulting Opportunities,” “Energy,” “LOAN 2990.”

Expressions of interest are to be submitted via the ADB website by November 1.
