Asset Performance Management Services

Asset Performance Management Services

GE offers Asset Performance Management (APM) services as a comprehensive business solution for customers that maximizes the value of their assets by optimizing maintenance and asset replacement strategies. These recommended solutions take into consideration budget constraints, the condition of existing assets, and the criticality of each piece of equipment.

To optimize infrastructure, GE offers integrated solutions to manage assets efficiently. Based on site inspections and asset condition assessments, GE’s experts analyze data to define the 'Asset Health Index' of equipment and provide recommendations on asset usage planning, operations, repair and replacement in order to maximize existing infrastructure

GE’s asset management services include:

  • Site inspection and diagnostics, including advanced non-intrusive inspection services
  • Continuous online condition-monitoring systems
  • Communications and integration solutions
  • Analytics for health index management
  • Utility business process integration

Whether its transmission, generation, distribution or industry and infrastructure electrical assets, GE provides the models and tools to enable customers to meet their company objectives in terms of:

  • Reliability - by reducing outages, assessing and mitigating operational risks
  • Cost efficiency - by maximizing asset life while optimizing maintenance costs and hedging risk costs, with particular care taken for ageing infrastructures
  • Strategy - by providing the information needed to establish corporate asset investment plans and performance objectives with regulators and shareholders
  • Organization - by capitalizing on electrical know-how in the context of an ageing workforce and aligning departments with consistent goals for increased efficiency

Visit the Asset Performance Management webpage to learn more about these services, as well as the APM services tailored to HV/MV equipment including circuit breakers, instrument transformers, disconnectors, gas-insulated substations, transformers and systems.

Renovation & Modernization Services

Renovation & Modernization Services

High voltage substations are very valuable grid assets, and are critical for grid reliability and availability. After decades of operation, grid operators may foresee risks of increasing failure rates in these assets due to electrical and environmental stress. Operators may also have needs for evolving power demand or for standard or technological enhancement.

GE supports the decision-making process by providing a cost efficient solution for substations and products requiring improved performance, or to resolve some obsolescence issues. GE’s engineered solutions are based on condition and life assessment of any high voltage equipment including third party original equipment manufacturer.

Renovation and overhaul to expand the life of ageing equipment

  • Conduct the overhauling of the substation
  • Change some key parts with no major upgrade

Modernization (retrofit and upgrade) to solve obsolescence

  • Add monitoring on operating assets, including continuous online monitoring
  • Implement last technology solution on brownfield assets
  • Change/retrofit some key parts with major upgrade, including circuit breaker retrofit for GIS

Extension to address evolving network needs

  • Install additional bays and/or poles to an existing substation (legacy, third party or mix)
