deterministic nature of tides, and independent of weather conditions or
climate change

Dynamic tidal power - High availability
1 Dynamic tidal power doesn't require a very high natural tidal range, but instead
an open coast where the tidal propagation is alongshore. Such tidal
conditions can be found in many places around the world, which means that the theoretical potential of DTP is very high. Along the Chinese coast for example, the
total amount of available power is estimated at 80 - 150 GW.

awarded a grant funding subsidy to the POWER consortium, led by Strukton and managed by
ARCADIS. The maximum grant is about 930.000 euro, which is matched by a similar amount of co-financing from the consortium partners. The
POWER group conducts a detailed feasibility study on the development of Dynamic Tidal Power (DTP) in China in a 3-year programme jointly conducted with Chinese government
institutes.

Rance tidal power plant - History
1 An early attempt to build a tidal power plant was made at Aber
Wrac'h in the Finistère in 1925, but due to insufficient finance, it was abandoned in 1930. Plans for this
plant served as the draft for follow-on work. Use of tidal energy is not an entirely new concept, since Tide mill|tidal mills have long existed in areas exposed to tides, particularly along

Ocean power in New Zealand - Tidal power
1 Tidal power is generated by capturing some of the energy in the tides as they cycle forth and back,
twice each day. Tidal devices can be weir or dam like structures (Barrage (dam)|barrages), used to hold the tide back, or turbines anchored
within the tidal stream.

1 The tidal power test site at the Fall of Warness, to the west of the island of Eday, was chosen for its high velocity marine currents which reach almost 4m/s (7.8 knots) at spring tides. The

1 Tidal power is a form of hydropower that converts the energy of tides into
electricity or other useful forms of power. The first large-scale tidal
power plant (the Rance Tidal Power Station) started operation in 1966. Although not yet widely used, tidal
power has potential for future electricity generation. Tides are more
predictable than wind energy and solar power.
