  19. 19. Indian Wave Energy Programme • The potential along the 6000 Km of coast is about 40,000 MW. • Available in more northern and southern latitudes. • Ocean Engineering Centre, Indian Institute of Technology, Madras in 1982. • wave energy potential along the Indian coast is between 5 MW to 15 MW per meter. OWC technology has been tried at Vizhinjam along the Kerala coast, near Thiruvananthapuram by National Institute of Ocean Technology, Chennai. (150 kW) The power plant delivers 75 kW during April – November ,25 kW from December - March. During June - September, it has peaks of 150 kW. The monsoon month's average power production was 120 kW. The cost of construction of the power plant was 99 lakhs Indian rupees. it produces 4.45 lakhs units of electricity per year. The unit cost stands 0.73 rupees, while the power from hydroelectric generators cost around 1.5 rupee per unit. 19 Source – “http://Raj_CA-OE_15.pdf” The plant was first commissioned in October 1991 Technical Specification OWC Capacity 150 kW power take-off mechanism is the Wells turbine electrical power to the grid The turbine design specifications : a)Type Constant chord, wells b)Profile NACA 0021 c)Chord 380 mm d)No. of rotor blades8 e)Hub/tip ratio0.6 The turbine was coupled directly to a 110 kW squirrel cage induction generator with a rated speed of 1000 rpm.
