BusinessGreen runs down the most promising developments for the world's emerging tidal power industry
Penzhina and Mezen Bay, Russia
Combined capacity: 102GW
Russia might not be known for its green energy policies, but the country does have two gigantic planned tidal power projects in the pipeline.
One is a massive 87GW barrage in Penzhina Bay off the northwestern coast, which would take advantage of the highest tides of any bay on the Pacific Ocean, costing around £200bn. Meanwhile, the smaller, but still huge, 15GW Mezen Bay project, would also be located off the northwestern coast.
The Russian Federation has backed an innovation centre for wave and tidal projects, however, it remains to be seen if or when these projects will be realised.
Annapolis Royal Generating Station, Canada
Capacity: 20MW
With its regal name, Annapolis Royal Generating station is the only tidal power plant in North America so far. It took four years to construct and could pave the way for a number of other schemes being developed in Canada's fast running waters.
Jiangxia Tidal Power Station, China
Capacity 3.2MW
Commissioned in 1980, it is the only tidal power station in China, costing the equivalent of around £1.2, to build. It might not be the biggest project in the world, but could act as a trailblazer for China's ambitious plans to increase renewable energy supplies.
Gulf of Kutch, India
Capacity: 50MW, but could be extended to 200MW
The Indian state of Gujarat is planning to host a commercial-scale tidal power station, and has signed a deal with Atlantis Resources to install the first 50MW off India's west coast. The facility could be expanding to 200MW in future. The Indian government has also identified the Gulf of Khambhat as a potential location for tidal power development.
