Nova Doubles the Shetland Tidal Array
Edinburgh-based tidal energy company Nova Innovation has achieved another world-first by doubling the size of their Shetland Tidal Array.
In 2016, the array of three underwater tidal turbines was the first of its kind and has been powering homes and businesses in Shetland ever since. A fourth turbine (Eunice) was added in 2020. Now, with the installation of the 5th and 6th turbines, it becomes the array with the largest number our turbines anywhere in the world.
Innovation & Cost Reduction
Turbines 5 and 6, Grace and Hali Hope, are connected via a pioneering subsea ‘hub’, sending power to shore by a single export cable. This innovation delivers significant savings on subsea cables, further reducing the cost of tidal power, essential as the industry scales-up and Nova develops larger sites with more turbines. In further proof of the commercial readiness of Nova’s technology, the Shetland Tidal Array’s years of operation has recently achieved the longest period of continuous monthly tidal stream power generation anywhere in the world.
Grace & Hali Hope
Shetland has benefitted directly from the array; job creation, utilisation of local companies and, more recently, the launch of the world’s first EV charge point powered purely by the tide. Children from Cullivoe Primary School are particularly enthusiastic about the project as they have been responsible for naming the latest turbine Hali Hope; Hali, meaning ‘of the sea, beautiful ocean’ and, Hope, for the future of our planet.
“As one of the pioneers of tidal energy Nova Innovation are demonstrating performance and reliability of the technology, and I welcome the expansion of its Shetland array. ”
“We are happy that the EU Horizon 2020 programme could support the development of tidal energy via the ENFAIT project and we hope that the good results of this project will attract further investors. Learnings from the continued operation and maintenance of all turbines, from Ailsa to Hali Hope, are extremely important and are a milestone for the whole ocean energy sector.”
