  • 3. Nandipur Hydel Power Plant  Constructed By RADE KONCAR  Installed Capacity 13.8MW  No. of units 3  Capacity of each unit 4.6MW  Head of water 24.4ft  Total cost of project 56.22MIL  Station Grid 66KV 4
  • 4. Low head hydel power Station  Low head hydro power applications use river current or tidal flows of 20 meters (approximately 66 feet) or less to produce energy.  No need to dam or retain water to create hydraulic head.  The head is only a few meters.  output varies with seasonal changes in stream flow 5
