Koyna Stage IV Hydroelectric Project

Encardio Rite provided advanced safety monitoring for the Koyna Stage IV Hydroelectric Project in Maharashtra, India. This expansion of the Koyna Hydroelectric Plant, with a capacity of 1000 MW, involves the use of geotechnical instrumentation, including piezometers, strain meters, and borehole extensometers. The system ensures peak hour power generation and supports the efficient operation of the facility. Continuous monitoring with real-time data allows for proactive maintenance and operational safety, meeting the growing energy demands of the region.

Koyna Stage IV Hydroelectric Project

The Koyna Hydroelectric Plant, a branch of the Krishna Basin, is a concrete dam 103.2 meters above the foundation, built on the Koyna River in Satara District, Maharashtra, India. It is the second-largest hydroelectric project in the country and impounds water to generate 1960 MW in four phases. The power plant was established in the year 1966 with the first two phases. Due to the increase in demand, the power plant was expanded with a new stage with a capacity of 1000 MW, called "Stage-IV". The installed capacity of this stage alone is 1000 MW. This stage is mostly used to cater to the peak-hour demands of the electric grid.

The power plant uses water coming from the Koyna River for phases I, II, and IV. In Phase IV, water is drawn directly from the reservoir in the Head Race Tunnel of length 4230 m and delivered to the Head Surge Tank.

Encardio-rite was awarded the sub-contract for the supply as well as installation of safety monitoring instrumentation for the project in 2010. The instrumentation included:
