Arunachal protests spread as groups oppose the 1,605 MW Menga dam
In 60 seconds: Protests against hydropower projects in Arunachal Pradesh have spread to the Upper Subansiri district, where groups now oppose the 1,605 MW Subansiri Upper Hydroelectric Project, known as the Menga dam. A 12-hour bandh on Monday saw arson, vandalism and clashes with police; equipment at an NHPC-linked office was damaged. Protesters want the project scrapped over fears for land, livelihoods and safety in an earthquake-prone area.
Why it matters
Arunachal holds much of India's hydropower potential. The protests show the tension between clean power, local rights and safety in a fragile Himalayan region.
Explain it simply
Building a big chai stall on a street brings more business, but if it blocks the homes and paths of people living there, they will push back. A dam in the hills is the same, only far bigger.
The 3-minute read
What happened
The bandh was called by the All-Tagin Students' Union with other student unions, land-affected forums and community groups. Police said a vehicle was set on fire, surveying tools were damaged and some policemen were injured. A public hearing on the project was cancelled.
Background
The Subansiri is a major tributary of the Brahmaputra. The protest follows large demonstrations elsewhere in Arunachal against the Siang Upper Multipurpose Project.
How it works
Protesters raise concerns about the environment, livelihoods, indigenous rights and the safety of a mega dam in a seismically sensitive region. Separately, China's foreign ministry said its forces strictly follow agreements in border areas, after reports of a faceoff with India in Arunachal.
What's next
The state government and NHPC will need to restart talks with communities. Without local consent, public hearings and clearances are hard to complete.
What it means for you
Hydropower is clean, but large dams affect forests, rivers and people downstream. Such trade-offs shape India's energy future.
Key numbers
- 1,605 MW: Capacity of the Menga dam project
- 12 hours: Length of Monday's bandh
Both sides
- Protesting groups: The project threatens land, livelihoods, indigenous rights and safety, and must be withdrawn.
- Supporters of hydropower: Dams provide clean electricity and can help manage water flows in the Brahmaputra basin.
Key terms explained
- Bandh
- A general shutdown called as a protest, closing shops, offices and transport.
- Hydroelectric project
- A dam and power station that make electricity from flowing water.
The story so far
- 2025: China begins building a mega dam on the Yarlung Tsangpo. In July 2025 China began building a huge hydropower project on the lower Yarlung Tsangpo, the river that becomes the Siang in Arunachal Pradesh and the Brahmaputra in Assam.
- 2025–26: Large protests against the Siang Upper Multipurpose Project. Communities in Arunachal have protested the proposed Siang Upper Multipurpose Project, India's planned large dam on the Siang, over fears of losing land and villages.
- Today: Protests now target the Menga dam
