Poseidon is a concept for a floating power plant that transforms wave energy into electricity. The power plant furthermore serves as a floating foundation for off-shore windmills, thus creating a sustainable energy hybrid. The demonstration plant named Poseidon 37 is 37 meters wide, 25 meters long, 6 meters high (to deck) and weighs approximately 350 tons.
Floating device in the Baltic Sea, near Lolland, Denmark.
Poseidon went into real sea test in 2008 off the shores of Lolland in southern Denmark and has completed 4 grid connected tests, the last one ending in 2013. The test site was grid connected with both a 690V and a 10 KV connection. The electrical infrastructure was installed in corporation with DONG energy.
In parallel with these testing activities the technology is currently (with a large group of partners) being scale up and engineered for the first full scale commercial unit. A P80 (a 80 meter wide construction including 5-8MW wind turbine and 2-3,6 MW wave. This facility will be installed in the UK together with DP energy. Two separate project companies have been established in the UK, one in Wales and one in Scotland.
Expected Operation Date:
P37 off shore tests (2008, 2010, 2012 and 2013)
P80 1 device: 2019
P80 4 devices: 2021
P80 +200 MW 2023 (at same site)
P37 has secured a 7 year test license at the Vindeby test site, including infrastructure and PPA. DONG Energy environmental department has been a great help in this process. The project has according to Danish law been in hearing and approved with the necessary documentation.
The platform has been placed in closed connection with an already existing off-shore wind turbine park in a non sensitive area, in all regards except for birds. The area is in/close to a shallow water sensitive bird habitat. Since no similar platform has never been launched FPP has to a high degree used already published EIA information from off-shore wind turbine parks, barges and similar. To address the issue of the birds FPP has chosen to monitor and count impacts and how the birds interact with the platform (for resting, etc.).
