Strategies include replacing wooden poles with concrete or steel, burying power lines and substation elevation
Grid hardening, also known as storm hardening, is a strategy employed by utilities to assess and mitigate potential risks in the electric grid. This involves taking proactive measures to strengthen key infrastructure and reduce outages and damages caused by storms or natural disasters. One such strategy includes replacing wooden utility poles with concrete or steel alternatives.
Wooden utility poles are commonly used in rural areas to support electrical wires and cables, keeping them insulated from the ground and out of the way. However, they are susceptible to damage from high winds, falling trees, and natural disasters. To harden the electrical grid, utilities may opt to replace wooden poles with more robust materials such as concrete or steel alternatives. These materials offer greater strength and durability, making them better equipped to withstand harsh weather conditions and falling debris. For example, a Stobie pole, commonly found in South Australia, is made of two steel joists held together by a slab of concrete, providing enhanced stability.
Another strategy to harden the electrical grid is to bury power lines underground. Above-ground power lines are vulnerable to damaging winds, flying debris, and falling trees, as seen in the case of Hurricane Ida, which caused widespread power outages in New Orleans. Burying power lines can protect them from these above-ground hazards. However, underground lines are still susceptible to water incursion driven by storm surges or flooding. Therefore, utilities must carefully consider the specific threats in their area when deciding between above-ground and underground power lines.
Substation elevation is another critical aspect of hardening the electrical grid. Substations are integral parts of the electricity distribution system, stepping up or down large voltages of electricity. While these substations are typically protected by fences or located within secure buildings, elevating them further can provide additional protection. By placing substations on higher ground or elevated platforms, the risk of flooding and water damage can be mitigated. Additionally, regular assessment and analysis of the entire network are crucial to identify risk areas and implement effective grid-hardening techniques.
