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.
