The ambitious forecasts of Scottish marine power during the first round of seabed leases in Pentland Firth and Orkney will be significantly shorter in reality.
The Crown Estate first unveiled 11 sites to developers in 2010 with the ambition of generating 1.6 gigawatts of electricity over the next 10 years – enough for one million homes.
However, market conditions mean that only one development has gone live with other schemes being put on hold for an undefined period of time.
The higher costs of other power sources and the failure of Atlantis to guarantee the minimum price for energy produced from its MeyGen site have left investors with cold feet.
Senior policy manager at Scottish Renewables Hannah Smith said: “It’s fair to say that the process of developing viable wave and tidal energy devices has suffered challenges and setbacks aplenty in recent years – but significant progress has been made, too.”
Smith added: “These innovative new technologies are unable to compete with the very low prices achieved by offshore wind, which has effectively left marine energy locked out of the mechanism to sell its power at scale.”
