Natural Power was awarded the contract by utility Repsol Nuevas Energias UK. The project is expected to consist of 180 wind turbines in the Firth of Tay region.
In addition, Natural Power will also be providing an advisory role on mammals.
Spain’s biggest oil company Repsol acquired a stake in three Scottish offshore projects in May this year.
The £50 million (EUR57 million) deal to buy Scottish developer SeaEnergy will see Repsol partner its Iberian neighbour EDP Renovaveis to develop two of the three sites.
In addition to Inch Cape, Repsol will have a 33% stake in the 1.5GW Moray Firth site and 25% of the 920MW Beatrice site in the Moray Firth to be developed jointly with SSE Renewables. It owns 51% of Inch Cape.
