Following the resounding popularity of the Chukha Hydropower Plant and its socio-economic bearings on folks of Bhutan and Asia, the proposal for the next hydropower plant within the Wangchu lake basin was conceived and triggered a pre-feasibility report ready in 1983. Following conversations held between their Majesty the 4th master of Bhutan therefore the then Union Minister of Energy, GoI, in January 1990, a high-level expert term was deputed by GoI to reconnoitre the many venture areas in February 1990. The expert staff suggested the prima-facie feasibility to two projects particularly, the Tala Project therefore the Wangchu Reservoir Scheme and suggested that detail by detail studies be used up. After that, the two governing bodies entered into a Memorandum of comprehending on November 25, 1990, for carrying away detail by detail investigations and scientific studies. The work was assigned by the MEA, GoI to M/s. Liquid and Power Consultancy Services (WAPCOS), an Undertaking regarding the Ministry of Liquid sources, national of Asia, vide an understanding of February 18, 1991. In July 1991, WAPCOS initiated website Surveys, Field Investigations and researches concerning hydrology, meteorology, topography, geology, seismology, geophysical and geo-technical properties, quarries for building products and ecological aspects.
The Tala Project is situated in Chhukha, Western Bhutan, simply downstream regarding the Chhukha Project. Field investigation work related to the Tala Project was completed in March 1993. After finalizing of work desk researches, a draft Detailed Project Report (DPR) was made by WAPCOS, on schedule, by August 1993. Various responses and suggestions about the draft DPR had been gotten during a presentation of the draft DPR. Your final DPR, including these comments/suggestions, ended up being prepared in October, 1993.
The contract the implementation of the Tala Hydroelectric Project ended up being finalized because of the two Governments on March 5, 1996, following which an independent human anatomy named the Tala Hydroelectric venture Authority (THPA) had been constituted for building, operation, and maintenance of the Project.
WAPCOS had been appointed once the engineering design Consultants toward Project Authority. The expertise of premier organizations associated with the GoI viz the Central Electricity Authority, Central liquid Commission, Central Water & Power Research facility, Central Soil & Materials analysis facility, Geological research of India and research of India were in addition distributed around the Project through WAPCOS. The nationwide Institute of Rock Mechanics (NIRM) still will continue to provide consultancy in instrumentation in a variety of appurtenants of Project.
