Overview
The Koyna Hydroelectric Project in Satara district, Maharashtra, is one of the largest completed hydropower projects in India.
Water from the Koyna dam on the Koyna river (a Krishna tributary) is sent west through tunnels down the Western Ghats to underground powerhouses, using the steep drop to the Konkan.
A strong earthquake in 1967 near the dam made Koyna a classic example of reservoir-induced seismicity.
