Nova said this now makes its array off Scotland “the world’s first grid-connected baseload tidal power station”.
Since October, the UK grid has been supplied by Nova’s Tidal Energy Storage System (TESS) demonstrator, which integrates Nova’s Shetland Tidal Array with Tesla’s battery technology to provide power on demand.
Nova Innovation chief executive Simon Forrest said: “By storing the clean energy generated by the natural ebb and flow of the tide, we can control the supply of electricity to the grid to match demand. This creates a consistent source of completely predictable power from a clean, sustainable resource.”
He said the company was now “looking forward to expanding our services to other markets and renewable projects”.
Forrest said that by linking tidal power with energy storage improves security of supply, reduces carbon emissions and helps to balance electricity supply and demand. “The predictability of the tide and the six-hour generation cycle times make it the perfect partner for energy storage.”
The project has been funded by the Scottish Government’s Low Carbon Infrastructure Transition Programme, which, supported by the European Regional Development Fund, is designed to accelerate the development and delivery of low-carbon infrastructure projects across Scotland.
Sam Gardner, Acting Director of environmental organization WWF Scotland, said: “Predictable renewable power and smart storage working in harmony is the holy grail of the transition to a renewable electricity system. It’s great that the Scottish government has backed this project and we hope it inspires politicians and others with the confidence to provide further support for ground-breaking technologies to cut climate pollution.”
