EDS HV Group Secures North Hoyle O&M Contract


EDS HV Group (EDS) to provide operations and maintenance (O&M) services at North Hoyle Wind Farm

Full turnkey services provided by EDS’s multi-skilled engineers and technicians.

EDS will manage operations, including network surveillance, high voltage (HV) safety management and marine coordination, from its 24/7 control centre.


High voltage engineering specialist, EDS HV Group (EDS), part of the UK’s leading marine services company – James Fisher and Sons plc, has been awarded a contract by energy company innogy renewables who manage the site on behalf of the wind farm owners Greencoat Wind UK plc, for operations and maintenance (O&M) management, which will maximise the availability of the high voltage (HV) network at North Hoyle Wind Farm in Liverpool Bay, Wales.


Following a competitive tendering process with other major players in the sector, EDS has been selected for its vast experience in O&M, managing HV infrastructure associated with over 1.5GW of renewable energy generation and a proven track record in providing a fast and efficient response in the event of a fault situation.


John Carey, North Hoyle Operations Manager said:

“We were very impressed with EDS’s technical proposal which demonstrated an excellent understanding of our HV requirements as well as showcasing their planned and reactive maintenance skills.   The breadth of their services specific to the offshore market and their ability to respond quickly made EDS a very good choice.” 


Running from Q1, 2019, the three-year contract will see North Hoyle’s onshore substation and export cables come under the remit of the EDS HV Control Centre, from which the HV network will be managed on a 24/7 basis. As well as carrying out planned maintenance, EDS will provide fault location services and emergency repairs if necessary.  


Ryan Murphy, Asset Manager at EDS said:

“A proactive maintenance regime based on condition monitoring of HV assets plays a key role in optimising efficiency and reducing operational costs. Our goal is to help clients to maximise availability in a safe manner, and at lowest cost, by carrying out planned maintenance as efficiently as possible and minimising any unscheduled maintenance. This contract award builds upon an already excellent relationship that EDS has with innogy and we look forward to continuing to provide the service levels that they have come to expect”


The Round 1 60MW North Hoyle project is an early pioneer of the UK offshore wind movement, and the UK’s first commercial wind farm constructed in 2004
