The Maithon Hydel Power Station is an underground power house located in the border of Dhanbad and West Burdaman districts of Jharkhand and West Bengal respectively. This hydro plant consists of 3 units which were originally commissioned from 1957 to 1958. All the units are Horizontal Francis machines. The plant is owned and operated by M/s. Damodar Valley Corporation (DVC). This plant is located on the river Barakar. The unit generated from this plant is shared between the two states (of India) – Jharkhand and West Bengal. It has the biggest reservoir in DVC. It has been designed for flood control & generates 60,000 kW of electric power. It has its unique underground power station, the first of its kind in South Asia. Underground tunnel: Horse shoe shaped (Length – 700ft; Width – 14ft; Height – 13.5ft). The power station has a total generating capacity of 60 MW with three (3) units of 20 MW each.

Unit # 1 & 3 of Maithon Hydel Station has outlived its service life and failing, Damodar Valley Corporation (DVC) decided to renovate and modernized Unit # 1& 3.

Brief Scope:
FLOVEL’s scope includes Renovation, Modernization of the existing plant Unit 1 & 3, which includes Reverse Engineering, Design, Engineering, Manufacture, Supply, Refurbishment, Erection, Testing, and Commissioning of Electro-mechanical works.

• Turbines and Generators
• Electrical and Mechanical Balance of Plant (BoP)
• Civil Works
• Switchyard

The both units are to be operated @ 20MW Capacity each

Highlights of this project with respect to FLOVEL are:

This project is significant for several reasons:

• Our Largest Horizontal Francis Turbine Project
  This is the largest Horizontal Francis Turbine project undertaken by FLOVEL to date. Successfully executing a project of this scale further strengthens our expertise in designing and delivering high-capacity hydroelectric projects and reinforces our position as a trusted partner for complex renewable energy infrastructure.

• First Renovation & Modernization Project for an Underground Hydroelectric Power Station
  This project marks FLOVEL’s first Renovation & Modernization (R&M) assignment for an underground hydroelectric power station. It represents a significant milestone in expanding our capabilities beyond new-build projects and demonstrates our expertise in upgrading aging hydro assets to improve efficiency, reliability, and operational life.

• Beginning of a New Customer Relationship
  The project also marks the beginning of our association with Damodar Valley Corporation (DVC), one of India’s premier public sector power utilities. This first contract establishes an important partnership and reflects DVC’s confidence in FLOVEL’s technical capabilities and project execution expertise.

• Our Commitment
  As the project progresses, FLOVEL remains committed to delivering the works safely, on schedule, and to the highest standards of quality and performance. We are confident that this landmark project will strengthen our presence in the hydroelectric sector, expand our capabilities in modernization projects, and create new opportunities for future collaborations.

It is a privilege for FLOVEL to partner with Damodar Valley Corporation (DVC) on this prestigious project and contribute to the modernization of one of India’s pioneering underground hydroelectric power stations.
