Medium Voltage Supervisors- Renewable Energy

Duties & Responsibilities

The MV Supervisor is responsible for the safe installation, testing, commissioning, operation, and maintenance of medium‑voltage electrical systems (typically 1 kV–33 kV) on renewable energy projects. This role ensures compliance with electrical standards, project specifications, and health & safety requirements while coordinating site activities and personnel.

• Supervise MV electrical works including: MV cabling (installation, jointing, terminations)
• Switchgear, transformers, RMUs, substations
• Oversee MV testing and commissioning activities:
  • Insulation resistance, VLF, primary/secondary injection
  • Protection relay testing and verification
  • Coordinate MV energisation, isolation, and switching activities
• Review and approve MV method statements, procedures, and ITPs
• Ensure correct interpretation of electrical drawings, schematics, and single‑line diagrams
• Interface with grid operators, utilities, and client representatives during grid connection activities. Enforce high‑voltage and medium‑voltage safety rules and permit‑to‑work systems
• Conduct toolbox talks, risk assessments, and job safety analyses
• Ensure compliance with:
  • Local electrical codes and grid standards
  • IEC, IEEE, or equivalent standards
  • Project HSE requirements and LOTO procedures
• Investigate incidents and near misses; implement corrective actions
• Lead and supervise electricians, technicians, and subcontractors
• Coordinate with civil, mechanical, SCADA, and commissioning teams
• Monitor progress, productivity, and quality of MV works
• Support punch‑list closure and handover documentation

• Electrical Trade Qualification, Diploma, or Degree in Electrical Engineering (or equivalent)
• MV/HV switching and safety certification (country‑specific)
• First Aid, Working at Heights, and Electrical Safety training
• Valid electrical license (where required by local regulations)
• Typically, 5–10 years in electrical works, with 3+ years supervising MV systems
• Proven experience in renewable energy projects such as:
  • Utility‑scale solar PV plants
