Oversee MV collector systems, turbine electrical interfaces, array cables and wind farm substation design.
Lead grid connection activities including grid code compliance, fault ride-through, reactive power capability and coordination with utilities and TSOs.
Manage electrical interfaces between wind turbines, MV collector networks, primary substations, SCADA systems and export cables or transmission lines.
Review and approve technical specifications for HV equipment, switchgear, transformers, cables and protection systems.
Support procurement activities including technical evaluation of electrical equipment, HV plant suppliers and OEM wind turbine electrical systems.
Support construction, commissioning, testing, energization programmes and achievement of COD.
Provide electrical input to contractual, commercial and technical risk management discussions.
Support O&M and Asset Management teams post-COD, including failure analysis and performance optimization.

Requirements

General Experience

10-15 years of professional experience in electrical engineering within power generation or renewable energy projects.
7–10 years of direct hands-on experience in wind energy projects above 200 MW.
Demonstrable experience in primary HV substation design and construction (132 kV, 220 kV, 400 kV or above).
Proven experience working under EPC, multi-contract or Owner-managed delivery models.
Experience working with utilities, IPPs, EPC contractors, turbine OEMs or engineering consultants.
