ELECTRICAL RELIABILITY ENGINEER (HIGH VOLTAGE)

Entity: GEGL

Position: Electrical Reliability Engineer (High Voltage)

Division / Department: Operations & Maintenance (OM) / Power (POW)

Location: Several Locations, Western Region, Ghana (West Africa)

Report Directly to: Electrical Reliability Superintendent

Subordinate: Assistant Electrical Reliability Engineer

Designation Level: Sectional Head

OBJECTIVE: The Electrical Reliability Engineer (High Voltage) is responsible for identifying, assessing, and mitigating reliability risks associated with all high-voltage (HV) electrical assets and distribution systems within the CCGT plant.

The role ensures the availability, integrity, and optimal performance of critical HV equipment, including power transformers, switchgear, transmission and distribution lines, protection and control systems, and high-energy distribution networks, through effective condition monitoring, diagnostics, and reliability-centered maintenance strategies.

This position plays a key role in maintaining operational excellence, minimizing unplanned outages, and safeguarding the long-term reliability, safety, and performance of the plant’s high-voltage electrical infrastructure.

KEY RESPONSIBILITIES:

ENGINEERING, PROCUREMENT & CONSTRUCTION (EPC)

• Support the EPC Project Team during Construction, Installation, and Commissioning of all HV electrical systems:

• Assist in reviewing Authorized For Construction drawings (AFCs), Single Line Diagrams (SLDs), protection schemes, cable routing, and commissioning checklists.
• Review redline and as‑Built drawings to verify accuracy and compliance with HV engineering standards.
• Provide technical oversight during the installation of HV components such as transformers, HV switchgear, breakers, isolators, and grounding systems.
• Recommend improvements to the HSE team to enhance electrical safety practices specific to HV energization and isolation.
• Support management of warranty claims and punch list items for HV equipment during and after commissioning.
• Ensure adherence to Quality Assurance and Quality Control (QAQC) for all HV installations, testing, and energization processes.

OPERATIONS & MAINTENANCE (OM)

• Ensure the reliability, availability, and maintainability of high-voltage electrical installations by supporting the Electrical Reliability Superintendent in implementing Life Cycle Asset Management (LCAM) for the following assets:

• HV transformers (power and auxiliary)
• HV, MV, and LV switchgear
• Circuit breakers, disconnect switches, and isolators
• Protection relays and schemes
• Busbars, insulators, and HV cable systems
• Neutral grounding resistors
• Lightning and surge protection systems
• Motors, generators, and auxiliary power distribution equipment
• Electrical controls and instrumentation associated with HV systems
• Cooling systems and transformer auxiliaries

• Design, develop, monitor, and refine maintenance plans that include:

• Predictive, proactive, preventive, and corrective maintenance tasks
• Effective use of diagnostic tools such as DGA, partial discharge testing, thermography, insulation resistance, tan delta, and contact resistance testing
• Optimized utilization of the Computerized Maintenance Management System (CMMS/CCMS)

• Provide input to HV electrical risk management plans addressing reliability‑related risks such as insulation degradation, transformer failure, circuit breaker misoperation, and protection malfunctions.
• Propose engineering solutions to chronic or repetitive HV failures through:

• Root Cause Analysis (RCA / RCFA)
• Reliability modeling and prediction
• Weibull analysis
• Fault Tree Analysis
• Statistical process control
• Failure Reporting, Analysis & Corrective Action System (FRACAS)
• Six Sigma (6σ) methodology

• Collaborate with the Operations Team to analyze HV electrical asset performance, including:

• Equipment loading and thermal performance
• Transformer efficiency and winding temperatures
• Breaker/trip frequency and reliability trends
• Overall equipment effectiveness (OEE)
• Remaining useful life (RUL) of HV assets
• Electrical losses, operational conditions, and cost impacts

• Execute predictive and preventive maintenance to prevent catastrophic HV failures and reduce unplanned shutdowns.
• Prepare supporting documentation for all tasks requiring a permit to work, ensuring compliance with HV switching, isolation, and grounding procedures.
• Maintain all regulatory documentation up to date, ensuring compliance with electrical safety codes, environmental standards, and industry regulations.

PROCUREMENT & LOGISTICS

• Provide support with all Purchase and Service Order Agreements relating to the maintenance of the plant.
• Ensure materials are available for planned maintenance, overhauls, and mandatory inspections.

QUALIFICATIONS:

• BSc in Electrical, Electromechanical, or Instrumentation & Control Engineering.

KNOWLEDGE & EXPERIENCE:

• A minimum of 4+ years of experience in the oil & gas industry, in power plant management, and reliability processes.
• Familiarity with regulatory requirements for operating plants, including Process Safety Management, OSHA regulations, EPA regulations, EEOC guidelines, and other federal and local requirements.

COMPETENCIES:

• Proactivity: Ability to define complex technical problems and develop a range of solutions in differing situations.
• Ability to manage technical issues in a continually changing business environment.
• Flexibility: Ability to operate flexible work practices to achieve optimum results.
• Good Communications: Consistently communicate. Be a good listener and negotiator.
• Work Diligently: Manage multiple projects and deliver promptly. 
• Training and Development: Accountable for self-development, training, and development of subordinates.
• Optimization: Navigate complexities and uncertainties, and drive efficiency through the use of technology.
• Organizational Skills: Excellent planning, organizational, and time management skills, and ability to coordinate activities across a wide range of disciplines.
