Maharashtra generates energy from sea waves

Mumbai, May 30 (IANS) Maharashtra has succeeded in generating 25 kw of electricity from sea waves.
Minister for Non-Conventional Sources of Energy Vinay Kore and officials witnessed the Wave Energy Power Project, which, using electricity generated from sea waves, got underway by blasting a huge concrete wall off the Arabian Sea shore at Guhagar in Konkan, around 300 km south of Mumbai, Friday evening.

“There are many projects in the world which generate electricity using tidal wave currents. This will not depend on tides, it will generate electricity from the powerful sea waves on the Konkan coast,” Kore told IANS.

The project was initiated by Maharashtra Energy Development Agency (MEDA) and implemented by Apar Urja Pvt Ltd. It was under preparation for over three years and has finally been a success, Kore said. The pilot project to generate 25 kw power cost Rs. four million.

“The next stage will be to generate 250 kw and then 1 MW by August, since the sea-waves are most powerful during the monsoons. Thereafter, we propose to take up commercial generation of electricity by this technique,” Kore said.

The state government has identified over 150 sites on the Konkan coast for deploying this technology.

Kore said that if the project succeeds in generating 1 MW of power, it will be implemented at other sites along the Konkan coast. However, he said, it was not possible to indicate a time-frame for the project.

He said Maharashtra currently faces a shortfall of around 4,000 MW a year.

“The cost of generating electricity by this method comes to less than a rupee per kw, as compared to other methods that cost a minimum of Rs.3.50 per kw,” Kore said.

According to MEDA official J.V. Torne, there is potential to generate over 500 MW annually along the state’s 720-km coastline, by using this technology.

“The available technologies in the world use only the upward thrust of sea-waves. The technology in Guhagar not only uses the upward thrust, but also the horizontal thrust and is also useful for low energy potential waves,” Torne explained.

“Apart from being 100 percent eco-friendly, it is also permitted under the Coastal Regulation Zone (CRZ) norms,” Torne said.
