JSW Ratnagiri Thermal Power Station, Maharashtra

The JSW Energy Limited Ratnagiri Thermal Power Station is a large coastal coal-fired power plant located in Ratnagiri district, Maharashtra. The plant plays a significant role in meeting the base-load electricity demand of the western region of India. Given its coastal location and high installed capacity, the power station relies on a robust and high-capacity cooling water system to ensure efficient condenser operation and stable power generation.

To meet the demanding cooling water requirements of the plant, large vertical turbine (VT) pumps have been installed as part of the circulating water system. These pumps are designed to deliver very high flow rates at relatively low heads, ensuring continuous and reliable supply of cooling water drawn from seawater intake systems. The pumping system supports uninterrupted plant operation under continuous base-load conditions while maintaining high operational efficiency.

Vertical turbine pumps are the preferred solution for coastal thermal power plants due to their ability to handle large volumes of seawater efficiently with stable hydraulic performance. Their vertical configuration allows installation in deep intake structures while occupying minimal surface area, making them ideal for circulating water systems in large power stations. The pumps supplied for the Ratnagiri plant are engineered for continuous-duty operation and optimized to minimize auxiliary power consumption.

From an operational reliability standpoint, the multi-pump configuration ensures redundancy and flexibility, allowing maintenance activities to be carried out without interrupting cooling water supply. The robust hydraulic and mechanical design enables long-term, trouble-free operation in marine environments, supporting safe and efficient power generation. This installation stands as a strong reference for high-capacity vertical turbine pumping solutions in coastal thermal power plants.
