Projects

The first tide generated electricity project was established at
Vizhinjam, Kerala

Vizhinjam fishing harbour is the site of a unique demonstrations plant that converts sea wave energy to elecricity and is given to the local grid. This plant is based on the oscillating water column (OWC) principle. A caisson was constructed in December 1990 at Vizhinjam and two generations of power modules have been tested as of today. The plant was first commissioned in October 1991. The physical processes in the energy conversion are understood to a much greater extent, leading to a threefold increase in absolute power from the plant.

At present, more than 80% cost of the wave energy plant is due to civil construction (concrete caissons). Considerable cost savings can be obtained using the concept of multi-functional breakwaters wherein a power module forms an incremental addition to a caisson breakwater. It is proposed to demonstrate the utility of this concept with the design and construction of a breakwater with a number of power modules.
