About the project

Tidal stream energy is an as-yet untapped form of predictable, clean power.

Orbital Marine Power has a vision to deliver a pioneering tidal energy project in the Westray Firth, Orkney, as part of our mission to help decarbonise communities in a sustainable and just way.

Project Update

Orbital was awarded an Option Agreement from Crown Estate Scotland for the Westray Project for 30MW, which would equate to approximately 12 Orbital devices installed across the site.

The construction of the Westray project would be expected to result in over £120m of domestic supply chain spend and create hundreds of jobs across construction and around a dozen new permanent jobs locally to provide operations and maintenance services.

About Orbital Marine Power

Orbital Marine Power (Orbital) is a visionary, renewable energy company focused on the development and global application of its pioneering floating turbine technology.

Headquartered in Orkney since 2002, the Orbital team is committed to using homegrown capabilities to build a new industry here in the UK for the future.

Tidal Stream Energy Global Resource

Delivering the global Net Zero mission will rely on decarbonising energy. With water being 800x the density of air, tidal presents an exceptionally dense form of kinetic renewable energy.

Night and day the tides ebb and flood, 365 days a year, offering a reliable, predictable form of clean electricity – increasingly important as power networks shift reliance from fossil fuels to more intermittent sources.


The Orbital Westray Project is located in the Westray Firth, Orkney, between the islands of Egilsay and Eday.  It is just to the north-west of the European Marine Energy Centre, Fall of Warness tidal test centre with similar characteristics and as such is an excellent location for the next stage in the development of this locally grown industry.
