Job Description

We seek a hands-on Electrical Technician to operate and maintain our 5 MW solar photovoltaic (PV) plant with integrated battery storage. You will ensure reliable 24/7 power production by performing routine inspections, preventive and corrective maintenance, and authorized switching of electrical equipment. The role requires strict adherence to safety protocols (LOTO/permit-to-work, OHS Act, etc.) and the ability to work on-site accommodation.

Key Responsibilities:

  • Monitor plant performance continuously (using SCADA); log data and alarms; track underperformance or faults.
  • Conduct scheduled and unscheduled maintenance on PV arrays, inverters, transformers, batteries and related balance-of-plant equipment. Perform fault diagnostics and repairs on electrical systems.
  • Execute authorized MV/HV switching (e.g. isolating transformers, feeders) under approved procedures; issue and manage permits for electrical work (Lock-Out/Tag-Out).
  • Carry out substation inspections (thermal scans, torque checks, visual) and ensure site cleanliness (vegetation control, equipment protection). Oversee external contractors (e.g. cleaners, security) as needed.
  • Maintain accurate records: fill work orders, service reports, switching logs and incident reports in the plant management system.
  • Ensure compliance with all HSE requirements: participate in toolbox talks, emergency drills, and stop operations if safety is at risk. Use personal protective equipment and promote a safety-first culture.
  • Assist in planning maintenance schedules and spare parts inventory. Support the Plant Manager and senior technicians with training and ad-hoc technical projects.

Required Qualifications & Certifications:

  • Electrical Trade Certificate (ex. Red Seal Electrician) or equivalent technical qualification.
  • Minimum N3/N4 in Electrical Engineering (or similar technical certificate).
  • ORHVS (High-Voltage Authorization) certification – mandatory for this role. Must be legally authorized as an Authorized Person for HV switching (or willing to obtain certification immediately).
  • Valid 3-phase Wireman’s Licence or equivalent (Installation Electrician) where applicable.
  • Proof of safety training: First Aid and LOTO/Permit-to-Work course certificates (or commitment to obtain quickly).
  • Valid South African driver’s license (Code B or higher) and willingness to travel to project sites.

Experience & Skills:

  • 3–5+ years of hands-on experience in solar PV plant operations, electrical maintenance or power plant O&M. Experience with battery storage systems (BESS) is advantageous.
  • Demonstrated fault-finding and troubleshooting skills on electrical equipment. Experience reading wiring diagrams and using diagnostic tools.
  • Familiarity with electrical SCADA systems and communication protocols (RTU, PLC) is a plus.
  • Solid understanding of medium/high-voltage power systems and switchgear. Experience performing thermographic inspections or predictive maintenance will be valued.
  • Computer literate (MS Office) for reporting and system updates. Good verbal and written communication in English.

Health & Safety Duties:

  • Act as a safety leader on site: strictly enforce the OHS Act, PPE use, and site safety rules.
  • Prepare and review Work Permits (LOTO), conduct daily safety briefings, and maintain a clean work area.
  • Obtain/maintain a medical fitness certificate per Annexure 3 (OHS Act) as required for electrical personnel.
