Geography and Location

Engineering and Infrastructure

The Kolkewadi Dam functions as a critical hydroelectric infrastructure asset within the Konkani region of Maharashtra, India. The engineering design integrates a primary dam structure with an underground power station located at the base, optimizing land use and structural stability in the hilly terrain.

The power generation capability of the plant is rated at 320 MW, utilizing water as the primary energy source. The facility is operated by the Maharashtra State Power Generation Company Limited (MAHAGENCO). The operational status of the plant is currently active, contributing to the regional energy grid.

Technical Specifications

The dam's hydraulic infrastructure features a central spillway equipped with three radial gates. This configuration allows for controlled water discharge, managing reservoir levels and downstream flow dynamics. The use of radial gates, also known as Tainter gates, provides efficient flow regulation with relatively low mechanical effort compared to other gate types, which is advantageous for the specific hydrological conditions of the Ratnagiri region.

The placement of the power station underground at the base of the dam structure is a significant engineering choice. This design minimizes the headrace tunnel length and reduces surface footprint, preserving the surrounding landscape in the Konkani region. The underground location also offers thermal stability for the turbine generators and protects critical mechanical components from surface weathering and seismic activity common in the Western Ghats area. The integration of the 320 MW capacity within this compact underground facility reflects modern hydroelectric engineering principles aimed at maximizing output per unit of civil construction.
