Three years after the Ministry of Water Power ordered a pre-existing report, a decision on the final site for the proposed 11.2 Gigawatt (GW) SIANG Additional Multipurpose Project has been learned to be organized on the final site “due to” local issues “. Sources said that the state -owned hydropower developers NHPC Limited are working for “progress” with stakeholders.
India’s strategic counter for China’s upcoming 60 GW hydrostation as a strategic counter of India, facing the project of villagers on the Siang River in Arunachal Pradesh, is facing opposition from the villagers, which is likely to be displaced.
An NHPC official said, “NHPC has identified some potential sites based on desk studies and site reconnaissance. However, necessary significant investigations have been done to reshuffle the final site to conduct a detailed investigation due to local issues. NHPC is constantly contacting stakeholders in the matter,” NHPC official said. The Indian Express,
On 20 May, NHPC transferred drilling equipment to a proposed site near Being in Siang district of Arunachal Pradesh. In April 2022, the NHPC requires drilling to finalize a work, pre-inflammatory report assigned by the Ministry. However, after the resistance of the residents, the drilling has not begun yet.

Detailed Project Report (DPR) – It is necessary to obtain regulatory approval and start civil functions – prepared after PFR.

The official said, “NHPC has deployed its manpower near (proposed) project site and collected the necessary resources to accelerate the important investigation required to complete the last site,” the officer said. In addition to Bing, proposed sites include Ugeng and diet dime.
The Ministry of Water Power did not respond to the requests of comment on the issue.

In December 2024, China approved its 60 GW project at Medog County on the River Yarlung Tsangpo, shortly before it enters Arunachal Pradesh as a Siang, which further makes the Brahmaputra down. The upper Siang project is expected to act as a buffer by regulating the water flow, regulating the water flow and protecting the downstream population and infrastructure.
The NHPC official said, “Strategic storage on the Siang River can act as a regulation plan to reduce the adverse effects of both the turns of water and artificial floods by the upstream Chinese growth.” “Regulated flow downstream is important to mold population, infrastructure, ecology and navigation, etc. due to adverse effects of sugar development in the Tibet Autonomous region. In addition, it will also increase renewable energy in the strategic storage grid,” the official said.
While about 30 percent flow of Brahmaputra arises in China, most of them come from rainfall within the catchment areas of India. Therefore, China’s dam is expected to have more impact on the upper parts of the river in Arunachal Pradesh.
Last month, addressing the protests against the project, Arunachal Pradesh Chief Minister Pema Khandu said: “Where hydroelectric is concerned, we will do what they say if they have objections. However, the upper Siang project is not only hydroelectric. We have to understand that it is a defense system.”

Citing the risks generated by the Chinese project, a senior official, a senior official, said on the condition of anonymity, “India should also go for a large -scale dam.” Beyond flood concerns, Chinese dams may also disrupt the flow of water for proposed downstream projects in Arunachal Pradesh.
While the upper Siang project has been under consideration for many years, in 2017, NITI Aayog manufactured a large-scale storage of 9.2 billion cubic meters, stating that “hydro-electric projects are being conceived on the Siang River, if the non-monsoon flows would become unlike, due to irreversible causes”.
India has about half of the 133 GW hydropower capacity in the Northeast, of which more than 80 percent are unused. Of the 60 GW estimated capacity, Arunachal Pradesh alone has about 50 GW lies.
“Once a large -scale dam is constructed with very large storage, it will take care of most of the issues faced by downstream projects. In addition, downstream projects should also be planned with proper storage according to cost profit analysis,” said NHPC officer.

PFR and DPR for the upper SIANG project are funded under the investigation of the Ministry of Water Power of Water Resources Development Scheme. Once completed, it will be the largest hydroelectric station in India.
