EMEC has delivered the world’s first internationally recognised power performance assessment to Verdant Power for its tidal array in New York, US.

During the 39-day test period, over tides, Verdant Power’s turbines performed with over 99% availability and generated 187kW at 2.5 metres per second at peak flood tide velocity.

The tidal power array s located at the Roosevelt Island Tidal Energy (RITE) site.
Overall water-to-wire efficiencies reached over 46%.

This is the world’s first marine energy Renewable Energy Test Report (RETR) and follows EMEC becoming the world’s first International Electrotechnical Commission (IEC) Renewable Energy Testing Laboratory (RETL) in August 2020.

It is also the first United Kingdom Accreditation Service (UKAS) ISO/IEC 17025 accredited power performance assessment to be completed by EMEC at a site outside the centre’s own test facilities in Orkney, Scotland.

Verdant Power chief technology officer Dean Corren said: “The high level of performance and reliability demonstrated by the Gen5d tidal energy system over this long-term deployment meets the requirements for commercial operations, and as the first project with formal third-party confirmation under IEC conformity, we look forward to accelerating development for Verdant Power and the marine renewables industry.”
