    With the proposed commissioning of a 50-Mw tidal power project off the coast of Gujarat in 2013, India [ Images ] is ready to place its first "seamark" that will be a first for Asia as well.

    London-based marine energy developer Atlantis Resources Corporation, along with Gujarat Power Corporation Ltd, has signed a memorandum of understanding (MoU) with the Gujarat government to start this project.

    The cost for the plant is expected to be in the vicinity of Rs 750 crore (Rs 7.50 billion). This plant is also is expected to be scaled up to 250 Mw.

    Timothy Cornelius, CEO, Atlantis Resources Corporation, said with just about 2 giga watt of tidal power installations in the world today, this is a completely new and uncharted power sources with immense potential. "Tidal power today is what wind energy was 10 years back," he said.

    Due to the high investment in setting up the project, a typical tidal power project is expected to break even between 8 and 12 years after commissioning.

    Despite the long gestation period to make it commercially viable, tidal power has unparalleled environmental advantages.

    "Tidal current power uses turbines to harness the energy contained in the flow of ocean tides. It is unique as like tidal movements, power output is highly predictable and sustainable with zero visual impact and the turbines are completely submerged. Tidal power is like putting a wind turbine subsea and the turbine rotors rotate slowly, causing very little environmental impact to marine flora and fauna," said Cornelius.

    The power offtaker would be Gujarat Power Corporation. The final cost of power per unit will be determined at the completion of front-end engineering and design (FEED) phase, but was expected to be competitive when compared to the large solar power projects planned for development in Gujarat, the company said.

    The project is currently owned by Atlantis and GPCL and project equity participants will be sought at the completion of FEED phase.

    Late last year, Atlantis became the turbine supplier to the largest planned marine power project in the world, MeyGen, a 378-Mw tidal power project in the Pentland Firth in Northern Scotland.

    Current estimates suggest 15 per cent of the world's power demands can be met by tidal current power sources, while the estimates for India are currently around 5 per cent of its annual demand for power.

    "It is only an estimate, but it could be certainly more than 5 per cent, inclusive of wave power and tidal power, from what we know now. However, resource investigation has just begun and with so much coast line, I would expect this number to increase significantly," said Cornelius.

    Sea water, which is 832 times denser than air, gives a 5 knot ocean current more kinetic energy than a 350-km an hour wind, thus allowing ocean currents to have a very high energy density.

    Accurate predictions of tidal current movements also make this one of the most predictable and, therefore, reliable sources of renewable energy available today.

    the environmentalist me loves this, the realist in me says - why spend money on this when there are more environmentally safe ventures that have a faster and proven ROI? this is the peoples money being used, it's their tax rupees.

    I am impressed. I would like to see this project in all coastal states and also another project of sea water filtration for drinking water and irrigation.

    Asia's first? Which Asia? Check below

    and this http://www.powergenworldwide.com/in...06/01/china-operates-tidal-power-project.html

    China operates tidal power project


    Published: Jan 6, 2006

    6 January 2006 - Asia's first tidal power station has gone into operation in Daishan County of eastern China's Zhejiang province. The 40 kW tidal power station was developed by Harbin Engineering University and assisted by Daishan Technology Bureau at a cost of CNY 1.8m ($223 000).


    Electricity is generated using the kinetic energy of the horizontal flow of seawater induced by the movement of the tide. The velocity of the tide flow is generally between two and four m/s around the Zhoushan islands


    The United Nations Industrial Development Organization (UNIDO) plans to build another tidal power station with a power of 120-150 kW.


    The global available reserves of the tidal energy tops 22 000 TWh annually according to the World Energy Council, which estimates that of this, 200 TWh is economically recoverable.

    Because this is Asia's first tidal power plant on a commercial scale.

    Check out the power ratings on the plants above: all in the KW's: 40 KW, 3200 KW/ 3.2 MW, etc. Barely enough to power a small colony of homes or a suburban district.

    The tidal power plant being installed in the Gulf of Kutchh is on an industrial scale- 50MW to start with, to be expanded to 2000 MW if the firm permits. Its only other competition is the one in S Korea- which, would probably be the 'first' and come in at a startlin' 1 GW.

    The following BBC article should clear some doubts:
