Tidal power now has the ability to generate half of Scotland’s energy needs. One of the local hydropower plants in the Pentland Firth between the mainland and Orkney Islands recorded a world record of 700 megawatt-hours of electricity in August. Even better? More power is expected to come from this source as the process becomes more and more efficient.
The new record was achieved by turning on a third Andritz Hydro Hammerfest turbine (AHH) at the MeyGen project during the neap tide in late August. Neap tides are when the sun and moon are close together and it creates the largest tidal waves. The third turbine was offline due to system maintenance and there will be four turbines overall in this phase of the project.
As of a recent system update on July 10th, Pentland Firth’s MeyGen project has generated two gigawatt-hours since opening up last December. It’s the world’s largest tidal energy farm, and it will only get bigger as all phases of the project should be completed by 2021. As for this new world record, it may not last very long.
