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)
