The Tripura government has drawn up a ₹100-crore plan to restore and modernise the Dumboor hydroelectric project in Gomati district, with technical support from NHPC Limited. Restoration work is expected to begin in December 2026, aiming to revive the flood-damaged facility and strengthen the state’s renewable energy generation capacity.
Tripura Power Minister Ratan Lal Nath announced the initiative, stating that technical assessments have been completed to determine the rehabilitation and modernisation requirements of the project, which suffered extensive damage during the devastating floods of 2024.
The restoration initiative is expected to bring the plant back into operation with a targeted generation capacity of 10–11 megawatts (MW), against its original installed capacity of 15 MW across three generating units.
NHPC Conducts Technical Assessment for Project Revival
NHPC, in collaboration with the Tripura government, has assessed the condition of the hydroelectric facility and identified the requirements for its restoration.
The technical assessment is a crucial step towards determining the repairs, equipment upgrades and modernisation measures needed to revive the ageing infrastructure. Work is expected to commence after the completion of the remaining preparatory formalities.
The proposed investment of around ₹100 crore reflects the state government’s push to restore the project and recover its power-generation potential.
2024 Floods Dealt Major Blow to Hydropower Generation
The Dumboor hydroelectric project was severely affected by the 2024 floods, which caused extensive damage and disrupted operations.
The plant was originally designed for an installed capacity of 15 MW through three generating units. The restoration plan aims to recover a substantial portion of this capacity, with the government targeting generation of 10–11 MW after modernisation.
The revival is also expected to help make productive use of existing hydropower infrastructure rather than leaving the damaged facility underutilised.
Boost to Tripura’s Renewable Energy Capacity
Tripura relies substantially on gas-based power generation. Reviving its hydroelectric infrastructure would help diversify the state’s electricity generation mix and strengthen its renewable energy portfolio.
The restoration of the Dumboor project is expected to deliver three key benefits:
- Renewable power generation: Bringing a damaged hydropower facility back into operation.
- Infrastructure modernisation: Upgrading ageing equipment and restoring the plant’s operational capabilities.
- Energy diversification: Strengthening hydropower’s contribution alongside the state’s existing power-generation sources.
The project also highlights the importance of resilient energy infrastructure in regions vulnerable to extreme weather events and flooding.
NHPC’s Role in India’s Hydropower Development
NHPC Limited, a Central Public Sector Enterprise under the Ministry of Power, is among India’s major hydropower development companies. Its involvement in the Dumboor restoration initiative underscores the role of public sector expertise in rehabilitating critical power infrastructure and supporting clean energy development.
With a proposed investment of ₹100 crore and restoration work targeted to begin in December 2026, the Dumboor project represents an important step towards reviving Tripura’s damaged hydropower capacity.
The pace of implementation and the extent to which the plant achieves its targeted 10–11 MW output will be key indicators of the project’s success.
