High Voltage Electrical Engineer O&M

Inch Cape is a 1080MW offshore wind farm situated 15km from the Angus coast in the North Sea. The power it generates will be transmitted 85 kilometres to a new substation at Cockenzie, in East Lothian from where it will enter the national transmission system. Inch Cape is a more than £3 billion infrastructure project that will make a significant contribution to the UK’s carbon emissions reduction targets.

Once complete its 72 turbines will generate enough electricity to power almost half the homes in Scotland.

The High Voltage Electrical Engineer is accountable for the technical integrity, safe operation, maintenance strategy, and performance optimisation of the windfarm’s HV electrical systems during the operational phase. This includes the offshore and onshore electrical balance of plant as applicable to the assets, such as wind turbine HV interfaces, array systems, offshore substation, export system interfaces, protection and control systems, switch gear, transformers, SCADA-linked electrical alarms, and associated safety documentation.

The post holder will ensure that HV assets are operated and maintained in a manner that is safe, compliant, available and commercially optimised, supporting turbine availability, export reliability, and long‑term asset value.

The role sits within the operational asset organisation and acts as a key technical authority for electrical systems during the O&M phase. There will be a strong emphasis on:

• HV operational safety and switching governance
• Fault diagnosis and technical response
• Maintenance of switch gear, protection, transformers, and auxiliary systems
• Management of electrical asset integrity and risk
• Support for outages, campaigns, and offshore interventions, and
• Capability to work within or progress toward Authorised Person / Senior Authorised Person frameworks

Location: Montrose, (3 days a week in the office, 2 days WFH)

• Act as the asset’s lead or delegated engineer for the integrity and reliability of HV electrical equipment during operations
• Maintain engineering oversight of HV systems including switch gear, transformers, cables, protection relays, earthing systems, metering, control systems, and electrical interfaces between turbines, array network, offshore substation, and onshore connection assets where within operational remit
• Develop, review, and improve preventative and condition‑based maintenance strategies for HV assets
• Review inspection, test, alarm, and defect data and determine corrective actions, risk ranking, and repair priorities
• Lead or support root‑cause analysis for trips, failures, insulation issues, protection mal‑operation, recurring alarms, and loss of generation events
• Support life‑cycle planning, obsolescence management, spares strategy, and end of life decision making consistent with asset management good practise, including ISO  principles

• Ensure that all HV work is planned and executed in compliance with site Electrical Safety Rules, permit to work arrangements, isolation standards, and control of hazardous energy requirements
• Prepare, review or approve switching programmes, isolation plans, sanctions for test arrangements, earthing arrangements, and return to service documentation, in accordance with authorisation level
• Provide technical oversight to Authorised Persons, Senior Authorised Persons, technicians, OEMs, and contractors undertaking HV work
• Support development and periodic review of Electrical Safety Rules, operational procedures, contingency plans, and emergency…
