Hellenic Cables has signed a contract with Seaway7 for the East Anglia THREE offshore wind farm which is being developed by ScottishPower Renewables (SPR).

A press release said that Hellenic Cables will be responsible for the engineering, manufacturing, testing and supply of some 275 km of 66 kV three-core inter array submarine cables and the supply of the associated accessories. Production will get underway in 2024. Once operational in 2026, it will be the second-largest offshore wind farm in the world. The cables will be manufactured at the company’s plant in Corinth, Greece.

“We are excited to have been awarded the cable supply contract ... and support the expansion of renewable energy in the UK,” said Hellenic Cables GM Konstantinos Savvakis. “We are proud to be part of this important project.”

The wind farm is located approximately 69 km NE off the Suffolk coast. Its 95 14.7MW turbines will have a combined capacity of 1,400 MW, generating enough green electricity to power the equivalent of more than 1.3 million homes.

Earlier this year, SPR awarded a contract for the high-voltage DC (HVDC) export power cable system for the East Anglia THREE offshore windfarm to NKT. The turnkey contract, with a contract value in excess of €250 million in market prices, comprises the design, manufacturing and installation of the complete 320 kV HVDC export power cable system.

SPR reports that East Anglia THREE will follow the same cable corridor as its flagship offshore windfarm – East Anglia ONE, which means that there is no need to create new cable trenches. “At ScottishPower, we’re committed to generating more homegrown green electricity in the U.K. for the U.K., and East Anglia THREE will be a huge part of that,” said Ross Ovens, managing director for the East Anglia Hub offshore windfarms.

Hellenic Cables has three cable production plants in Thiva and Corinth (Greece) and Bucharest (Romania) and two auxiliary production plants in Oinofyta (Greece) and Blagoevgrad (Bulgaria). The Corinth production unit was described as one of the largest and most advanced submarine cable plant in the world.
