Purulia Pumped Storage

Encardio Rite provided complete instrumentation and monitoring for the Purulia Pumped Storage Project, the largest of its kind in India. The project involved a 95 m high, 310 m long lower rock-fill dam and a 65 m high, 800 m long upper rock-fill dam, with a reversible pump turbine/generator motor. Key instruments installed included piezometers, strain gauges, borehole extensometers, load cells, and more, providing continuous data for operational efficiency and safety.

Purulia Pumped Storage

The 900 MW Purulia Pumped Storage Project is the biggest project of its kind in India. The project consists of a 95 m high, 310 m long lower rock-fill dam and a 65 m high, 800 m long upper rock-fill dam. The special feature of the pump storage scheme is that it has a reversible pump turbine/ generator motor.

Both the dams have been instrumented by Encardio-rite, including the penstock, tunnels, and underground powerhouse. The scope of work included supply, installation, monitoring, reporting, with data evaluation.

Extensive instruments used in the project include apiezometer,strain gaugefor penstock, boreholeextensometer, anchor boltload cells, vertical and horizontal settlement devices, seepage measurement device, geodetic targets, portablereadout units, and seismographs.
