Harnessing the power of the tides with Nova Innovation
Our work with Nova Innovation shows the importance of exploring new renewable sources.
The Shetland Tidal Array
Today, nearly half of the UK’s electricity is generated from renewable sources. However, in order to reach the net zero target, we need to further unlock the vast potential of these resources. This includes tidal power – a predictable and reliable natural energy resource. As an island nation with access to some of the world’s most powerful tides, the UK is well placed to exploit this natural advantage, transforming our energy landscape and driving us closer to a sustainable future.
Scotland holds exceptional potential for tidal energy, thanks to its numerous coastal towns and villages. It’s already home to the world’s first offshore tidal array - the Shetland Tidal Array in Bluemull Sound - located between the islands of Yell and Unst.
Installed by Nova Innovation, in 2016, the three turbines connect to the UK grid supplying clean, renewable energy to the local homes and businesses.
A key advantage of tidal power is its predictability. The Shetland Tidal Array combines power-generating turbines with battery technology, harnessing the reliable energy generated by the ebb and flow of the tide. In 2023, it set a global record for the longest period of uninterrupted monthly tidal stream power generation.
With our fixed PPA product, Nova benefits from guaranteed income stability and protection against market fluctuations, ensuring a steady revenue stream.
Great care was taken to ensure the project didn’t have an adverse effect on the area’s marine wildlife.
Before construction began, environmental monitoring teams gathered baseline data on seabird and cetacean populations and behaviour, to track any potential changes. The data gathered has shown that the array’s operation hasn’t impacted their foraging behaviour or mortality rates.
The turbines were designed to sit on the seabed, anchored by ballast - simplifying both installation and removal, while minimising disturbance to the marine environment.
With a capacity of 300kW and capable of generating predictable power and energy on demand, the array provides a reliable, clean microgrid which directly benefits the local community. Battery storage and electric vehicle (EV) charge points are connected, including the world's first EV charge point powered purely by the tide.
We’re already using more renewable energy sources in our electricity mix, and our work with Nova Innovation demonstrates the potential to go even further. The more we can enhance our renewable supply offering, the more we can connect customers to clean energy sources and the better placed we’ll be to improve the future of our planet.

I think the most rewarding thing for Nova is seeing the natural ebb and flow of the tide powering the turbines day after day, and year after year. They’ve been powering homes and businesses in Shetland for more than 8 years now, whilst we continue to set new records.
Chief Business Officer at Nova Innovation
This project is really unique because it has the tidal array, the battery, and it creates a micro grid environment. That means the community gets benefit directly from the tidal array.
