As Siang row simmers, questions over whether stakeholders were consulted

The Siang Upper Multipurpose Project, or SUMP, is a proposed large hydropower project linked to the Siang River region of Arunachal Pradesh. It is important because it could reshape local communities while serving wider national goals. The central and state governments describe it as essential for national security and for countering China’s mega dam project.

SUMP has not reached construction. The article states that it is currently at the pre-feasibility survey stage. A pre-feasibility study examines whether a proposed project appears workable before more detailed planning, though it does not itself approve construction. The government has also discussed possible alternative towns for Geku and Yingkiong.

The project remains contested. SIFF says communities were not properly informed or consulted, while the government says it will continue with the PFR. Officials say they are preparing conditions for the survey to resume after alleged arson and vandalism in Pasighat. Trust in the Siang Valley remains a central issue.

The proposed project has a capacity of 11,200 megawatts. That figure measures the maximum electrical power the project is designed to generate at a given time. It places SUMP among the largest hydropower proposals discussed in India. The article therefore describes it as potentially India’s biggest hydropower project.

Its scale matters beyond electricity production. A project of this size would require extensive planning, surveys, preparatory work and decisions affecting landowners and communities. Indigenous communities along the Siang River say it could threaten their livelihoods and cultural heritage. The government, however, presents the project as a national security priority connected to China’s mega dam project.

The project is still only at the pre-feasibility survey stage. That means its proposed capacity is not the same as electricity already being generated. Whether the project proceeds depends on further assessment and government decisions, while opposition remains strong because SIFF says affected communities were not adequately consulted.

SIFF’s central complaint is that affected people were not taken into confidence before planning advanced. Spokesperson Tagori Mize said the government did not consult either private landowners or community landowners. The forum says people were not adequately informed about the pre-feasibility survey or invited to discuss the project’s merits and demerits.

The dispute is also about trust. SIFF says a lack of transparency and public awareness has made communities suspicious of government decisions. Mize argued that senior leaders have sometimes said the dam will be built regardless of objections. That perception has strengthened opposition, including the demand that even the pre-feasibility report should not proceed.

The government gives a different account. Minister and BJP MLA Ojing Tasing denied that the memorandum was signed under duress and said the government would continue with the PFR. The disagreement shows why consultation matters: communities want a meaningful role before surveys, relocation plans or construction decisions affect them.

A pre-feasibility report is an early study used to test whether a proposed project appears practical. It generally considers broad technical, financial, environmental and social questions before a detailed feasibility report and construction decision. It is not the same as final approval. For a large dam, this stage can shape later choices about design, land, settlements and affected families.

The article says SUMP is currently at the pre-feasibility survey stage. The September 2025 MoU states that, if the project is feasible, preparatory work would be carried out in consultation with affected families. This makes the report important because its findings would influence whether the project advances and what preparation might follow.

SIFF questions the process and says it does not want even the PFR to happen. Mize also questioned how alternative towns for Geku and Yingkiong could be approved while the PFR was incomplete. The government says it will continue with the PFR and is preparing for its resumption.

If SUMP is built, the most direct concerns described in the article involve people’s livelihoods, cultural heritage and settlements. Indigenous communities along the Siang River argue that the project threatens the sources of life and work tied to their surroundings. They also say it could damage cultural heritage, which includes the community’s connection to its land and river.

The article gives a concrete sign of possible settlement change. Mize said the government announced Cabinet approval for alternative towns for Geku and Yingkiong villages. The article does not establish exactly how many people would move or what specific livelihood losses would occur. It does show that relocation and preparation are already part of the political debate.

The consequences remain uncertain because SUMP is only at the pre-feasibility stage. The government says preparatory work would involve affected families if the project proves feasible. SIFF disputes the process and opposes even the PFR, while officials say the survey will continue.

A memorandum of understanding records commitments between parties. In a major project, it can shape how residents understand consultation, preparation, compensation and support. It may also provide a basis for asking whether the government has honoured its promises. However, an MoU’s exact legal effect depends on its wording and applicable law; the article does not explain whether this MoU creates enforceable rights.

The September 2025 MoU says preparatory work would be carried out in consultation with affected families if SUMP proved feasible. It also promises economic, social, cultural and educational empowerment for project-affected families. SIFF disputes how agreement was reached, alleging that multiple members of some families were counted as separate households.

That disagreement affects the credibility of consent. SIFF says like-minded people were used to create a majority, while Ojing Tasing denies the MoU was signed under duress. The dispute means consultation, household counting and promised protections will remain important if the PFR resumes or the project advances.

A hydropower dam stores or channels river water so that moving water turns turbines. The turbines drive generators, producing electricity. This makes hydropower a way to supply large amounts of power from a river system. The article identifies SUMP as an 11,200-MW proposal, although it has not reached construction or electricity generation.

The national benefit described here is strategic as well as energetic. The central and state governments call the project essential to national security and to countering China’s mega dam project. Large planned capacity is another reason officials present it as nationally important. These benefits are weighed against local effects rather than replacing them.

For Siang communities, the possible costs include threats to livelihoods, cultural heritage and settlements. The article mentions alternative towns for Geku and Yingkiong, but does not detail the final impact. The conflict shows that a project can be nationally significant while still requiring transparent consultation with affected people.
