Overview
The Kaplong Hydroelectric Project stands as the largest dam in the Andaman & Nicobar Islands, serving as the primary hydroelectric power generation facility for the archipelago. Located in the North and Middle Andaman district, the structure is built across the Kalpong River at Nabagram Diglipur. As the only major hydro project in the region, it plays a critical role in the energy infrastructure of the Indian territory, providing a renewable source of electricity to support local consumption and grid stability.
The facility has an installed capacity of 5.25 MW, utilizing water as its primary fuel source. The project was executed by the National Hydroelectric Power Corporation (NHPC) and is currently operated by the Electricity Department of Andaman & Nicobar Administration. The dam was completed in 2001 and was officially commissioned on 1 September 2001 by Shri M. Kannappan, the Minister of State for Non-Conventional Energy Sources at the time. Notably, the project was commissioned 15 months ahead of its initial schedule, marking a significant milestone in the administrative and engineering efforts to develop the islands' power sector.
As an operational hydroelectric powerplant in India, the Kaplong project represents a key investment in non-conventional energy sources for the region. Its strategic location on the Kalpong River allows for consistent water flow, which is essential for maintaining the 5.25 MW output. The successful completion and early commissioning of the dam highlight the collaborative effort between national engineering bodies like NHPC and local administrative departments. The project remains a vital component of the Andaman & Nicobar Islands' energy mix, contributing to the reduction of reliance on diesel-based power generation in the remote island territory.

Commissioning and Operational Handover
The Kaplong Hydroelectric Project was officially commissioned on 1 September 2001. The commissioning ceremony was presided over by Shri M. This event marked the formal transition of the facility into operational status, ready to contribute to the power supply of the Andaman & Nicobar Islands.
Following its commissioning, the operation of the dam was handed over to the Electricity Department of Andaman & Nicobar Administration. This department has been responsible for the ongoing management and maintenance of the facility, ensuring its continued contribution to the region's energy infrastructure. The handover to the local electricity department facilitated localized control over the hydroelectric resource, aligning the plant's operations with the broader energy planning of the administration.
Why it matters
Its significance extends beyond its physical scale; it represents the primary hydroelectric asset for the territory, providing a critical renewable energy source in a region often reliant on diesel generation. The project is located across the Kalpong River at Nabagram Diglipur within the North and Middle Andaman district, a strategic placement that allows it to harness local water resources to serve the immediate community.
Regional Power Supply and Community Impact
Operated by the Electricity Department of Andaman & Nicobar Administration, the plant plays a vital role in the local power grid. With a capacity of 5.25 MW, it provides essential electricity to Diglipur and nearby towns, enhancing energy security for the northernmost settlements of the islands. This localized generation reduces the logistical burden of transporting fuel or extending long transmission lines from the main island of South Andaman. The commissioning of the project in 2001 marked a milestone for regional development, offering a more stable and environmentally friendly power source compared to traditional thermal options.
Comparative Role in the Islands' Energy Mix
In the broader context of the Andaman & Nicobar energy landscape, the Kaplong project serves as a key component of the renewable energy portfolio. While the islands have explored various energy solutions, this hydroelectric facility remains the largest of its kind in the territory. Its operational status continues to contribute to the diversification of the energy mix, reducing the carbon footprint of the archipelago's power generation. The project was executed by NHPC and was commissioned 15 months ahead of schedule, highlighting efficient project management and early realization of benefits for the local population. The involvement of Shri M. Kannappan, the Minister of State for Non-Conventional Energy Sources, during the commissioning on 1 September 2001, underscored the national importance placed on integrating non-conventional energy sources into the islands' infrastructure.
Infrastructure and Operational Significance
The dam's construction across the Kalpong River demonstrates the feasibility of hydroelectric power in the unique geographical setting of the Andaman & Nicobar Islands. As the sole major hydroelectric infrastructure in the archipelago, it sets a precedent for future renewable energy projects in the region. The Electricity Department of Andaman & Nicobar Administration's management of the plant ensures that the generated power is effectively distributed to meet the growing energy demands of Diglipur and surrounding areas. This project not only provides electricity but also contributes to water management and potential irrigation benefits, although its primary designation remains power generation. The successful operation since 2001 validates the technical and economic viability of hydroelectric solutions in island territories, offering a model for sustainable energy development in similar geographic contexts.
What are the economic benefits of the Kaplong Project?
The Kaplong Hydroelectric Project serves as the primary source of renewable energy for the Andaman & Nicobar Islands, providing critical infrastructure support to the local population.
