The expert committee of the Union Ministry of Environment has given its recommendation to grant environmental clearance to the Oju Hydroelectric Project. This project is of 2,220 megawatts on the Subansiri River in Taksing, Arunachal Pradesh, near the China border.

The expert committee of the Union Ministry of Environment has given its recommendation to grant environmental clearance to the 2,220 megawatt Oju Hydroelectric Project located on the Subansiri River in Taksing, Arunachal Pradesh, near the China border.
According to the Environmental Impact Assessment report of the project, there are several other proposed hydroelectric schemes in the Subansiri basin - Nyare, Naba, Nalo, Dengser, Upper Subansiri, and Lower Subansiri.
According to the minutes of the meeting held on September 12, the EAC mentioned that the Subansiri basin studies were finalized in 2014 and the information given in them was more than a decade old.
This project is proposed about five kilometers downstream from Redi village in Taksing block of Upper Subansiri and will be constructed by Oju Subansiri Hydro Power Corporation Private Limited.
The primary powerhouse is designed for 2,100 megawatt power generation, with an additional 120 megawatt power generation from a dam-toe station.

Subansiri River

Origin: It originates in Tibet and is the largest tributary of the Brahmaputra.
It is a trans-Himalayan antecedent river.
Course: Enters Arunachal Pradesh of India, flows through Assam, and joins the Brahmaputra. This river is also called the "Golden River" due to the gold dust found in its waters.

Sawalkot Hydroelectric Project

After the Pahalgam terror attack (2025) and the suspension of the Indus Waters Treaty (IWT), the process has been started to expedite approval for the long-pending Sawalkot Hydroelectric Project on the Chenab River, considering it a project of strategic and energy importance for Jammu and Kashmir (J&K).
Sawalkot Hydroelectric Project: It is a 1,856 megawatt "run-of-the-river" hydroelectric project (in which the natural flow of the river is used and very little or negligible water storage is done), located on the Chenab River (a western river under the IWT) in Ramban district of Jammu and Kashmir.
The project was started in the year 1984 and has faced various delays over the years. It has been declared a project of national importance, which includes the construction of a concrete gravity dam and a reservoir.
After the project starts, it is expected that more than 7,000 million units of electricity will be produced annually from Sawalkot, making it one of the largest hydroelectric projects in India.

Tato-I and Heo Hydroelectric Projects

Prime Minister Narendra Modi unveiled several major infrastructure projects in Arunachal Pradesh worth ₹5,125.37 crore, marking an important step towards regional development and energy security.
Among these major projects are two large-scale hydroelectric projects in Shi Yomi district. The 186 megawatt Tato-I hydroelectric project, with an estimated cost of ₹1,750 crore, will be developed jointly by the Arunachal Pradesh government and the North Eastern Electric Power Corporation Limited (NEEPCO).
It is estimated to generate about 802 million units of electricity annually. The 240 megawatt Heo project, costing ₹1,939 crore, is also a collaborative project between the state government and NEEPCO and is expected to generate about 1,000 million units of electricity per year.
Modi also laid the foundation stone of a convention center in Tawang, which will be built at a cost of ₹145.37 crore under the PM-DevINE scheme. With a capacity of more than 1,500 people, this center will meet international standards and aims to promote tourism and showcase the cultural heritage of the region.
