Grid Hardening

Hardening the Grid:  Reinforcing the T&D infrastructure to prevent or reduce the damage from extreme weather events.

Right selection of poles, towers, and wires:

  • Dual OHGW to reduce the potage caused by lightning.
  • OPGW to provide the communication path across the grid, enhancing the cybersecurity and improving reliability.
  • New Insulator design and materials provide greater reliability.
  • Higher Capacity, steel reinforced conductor allows for more efficient power flow and reduce electrical losses.
  • Greater clearances between electrical lines reduces outages caused by animal and provides safer working conditions for line crews.
  • Sturdier steel poles/concrete poles improve resiliency during storms, provide longer lifeexpectancy and lower maintenance costs.
  • Improved grounding provides better lightning performance and safer operation of T&D system.
     

     

     

     

Flooding can create tremendous issues for transmission substations
    Identify the substations which are vulnerable to flooding.
  • Plan for temporary and permanent hardening measures.
  • For permanent solutions, install sheet piles flood walls that are constructed of composite materials to resist decay and rust.
  • Raise substation equipment above flood level.
  • Install flood monitor sensor to alert rising water level.
  • Substation control houses can be designed for withstand a direct hit from EF3 tornado with back-up control houses available on short
     
     
     
     
     

Fire Prevention and Detection:Severe drought conditions coupled with high winds and other factors, have resulted in an increased number and severity of wildfires that can devastate natural habitats and communities.

    Implement wildfire mitigation plan to monitor weather and equipment.
  • Enhance inspections process of all overhead power lines in high fire risk areas and apply preventive maintenance to reduce risks of ignition.
  • Use fire-resistant poles, composite cross-arms, and covered conductors in high fire risk areas.
  • Install current limiting fuses that interrupt current more quickly to boost reliability by segmenting circuits to isolate problems.
  • Install HD camera that enable fire agencies to observe potential fire activity.
  • Install weather stations with multiple sensors to provide real time weather data.
  • Evaluate the ability to install new access roads and increase line ROW.
  • As a last resort, cut power to high fire areas when winds reach above a certain predetermined threshold
