What You'll Learn
Electric companies upgraded communication systems and mobilised utility workers
In the wake of Hurricane Sandy, utility companies in New York and New Jersey were forced to re-evaluate their disaster response strategies. The storm caused widespread power outages, with half a million people losing power for over a week. In the aftermath, utility companies focused on upgrading their communication systems and mobilising utility workers to restore power more efficiently in future storms.
Upgrading communication systems was a key area of focus for utility companies. In the past, communication breakdowns had hampered response and recovery efforts. Citizens with cell phones can be a valuable source of information during a disaster, but this relies on functioning cell networks and the ability for people to charge their phones. Upgrading communication systems helps improve situational awareness and facilitates more effective response planning.
To address this, utility companies invested in more resilient and reliable communication infrastructure. They also improved their monitoring capabilities to better track and respond to storms. Upgrading communication systems involved enhancing coordination and management processes to ensure a more streamlined and efficient response during and after a storm.
Mobilising utility workers was another crucial aspect of the utility companies' strategy. Restoring power quickly requires additional manpower, and utility companies recognised the benefits of engaging storm restoration contractors to supplement their in-house crews. By mobilising utility workers from other regions and partnering with specialised contractors, companies could increase their capacity to repair storm damage and restore power more rapidly.
In addition to upgrading communication systems and mobilising utility workers, companies also implemented other measures to enhance their preparedness and response. These included systematically replacing older transmission lines, pruning trees to minimise the risk of fallen branches damaging power lines, and relocating critical electrical equipment to upper floors in flood-prone areas.

They replaced old transmission lines and trimmed trees
In preparation for Hurricane Sandy, electric companies replaced old transmission lines and trimmed trees to mitigate the impact of high winds and flooding on power lines and electrical equipment.
Hurricane Sandy, the largest Atlantic hurricane on record, caused devastating damage to the energy infrastructure. The hurricane's high winds knocked down power lines, and rising seas flooded electric substations. As a result, electric companies took proactive measures to strengthen the power grid and reduce potential damage from falling trees.
One crucial step was replacing old and damaged transmission lines, which are essential for connecting power sources to end-users. These lines are often made of rubber and metal, and they can become worn out or damaged over time, leading to leaks and other issues. By replacing these lines, electric companies aimed to ensure a more reliable and stable power supply during and after the hurricane.
Additionally, electric companies focused on trimming trees and branches that could potentially fall on power lines. Falling trees and branches posed a significant risk of damaging power lines and causing widespread power outages. To address this, electric companies scheduled regular tree trimming and maintenance near power lines, and they also responded to reports from residents about overhanging branches. In some cases, power companies would disconnect the power lines before trimming to ensure the safety of their workers and the public.
These measures were crucial in minimizing the impact of Hurricane Sandy on the power grid. By replacing old transmission lines and proactively trimming trees, electric companies could reduce the likelihood of power disruptions and speed up recovery efforts in the event of damage or outages. Such preparations are standard procedures for electric companies when facing impending natural disasters, as they play a vital role in maintaining the resilience and reliability of the power supply infrastructure.

Utility crews were supplemented to restore power quickly
Hurricane Sandy was the largest Atlantic hurricane ever recorded, with devastating consequences. The storm caused high winds that brought down power lines and rising seas that flooded electric substations. In the wake of the hurricane, utility companies in New York and New Jersey had to supplement their crews to restore power quickly.
Matrix NAC, a storm restoration contractor, supported five utility companies with 300 crew members who performed emergency storm damage repairs. Supplemental crews were crucial in reducing the duration of the outage. The Associated Press reported that 95% of New Jersey customers had their power restored within 11 days, while it took 13 days for 95% of New York customers to regain power.
To expedite the process, utility companies engaged additional manpower and resources. They also improved their storm monitoring and mobilization capabilities, upgraded communication systems, and replaced older transmission lines. The ability to call in extra help was vital in restoring power quickly, as every day without electricity poses a significant hardship for customers.
In addition to the efforts of utility companies, the federal government played a crucial role in the aftermath of Hurricane Sandy. The Coast Guard helped open the ports, and the Secretary of Homeland Security issued a temporary waiver of the Jones Act to allow additional fuel tankers from the Gulf of Mexico to provide more fuel resources to the affected region. These measures ensured that generators and fuel were available to meet the region's energy needs during the recovery process.

Critical electrical equipment was moved to higher floors
In the wake of Hurricane Sandy, it became clear that critical electrical equipment should not be placed in basements or on ground floors in flood zones. In the days and weeks following the hurricane, water damage to critical electrical equipment on lower floors dramatically slowed electric restoration in many locations. In New York City, hospitals and other medical facilities, including the Bellevue Medical Center and Coney Island Hospital, suffered considerable damage to research, medical, and electrical equipment located on lower floors.
In the aftermath of the hurricane, electrical contracting firms from across the country dispatched teams to work with electric utility workers to restore power to the affected areas. E-J Electric, for example, worked to restore electrical service and distribution equipment in a 27-story office building in New York's financial district, where all equipment had been damaged by water. They also surveyed and repaired 29 public housing buildings on Coney Island, where the switchgear rooms had been submerged, leaving the buildings without power.
To get power back on, local utilities organized Mutual Assistance Groups, a tool used by the utility industry to respond to storms. They moved emergency workers and equipment into position, supplementing their crews with workers from other states. Matrix NAC, for instance, supported five utility companies with 300 crew members who performed emergency storm damage repair.
In the long term, building owners are considering relocating their electrical infrastructure to higher floors to protect against future storms.
