What Causes Power Outages During Storms?


Storms have a way of reminding us how dependent modern society is on electricity. The lights flicker, devices stop working, and entire neighborhoods go dark while the wind howls outside. But what exactly causes power outages during storms? The reasons are often tied to the weather’s direct impact on the grid and the growing strain on an aging electrical system.

Common Weather-Driven Causes of Outages

Different types of adverse weather present unique challenges for the grid. Here’s how each one is capable of triggering a storm-related power outage:

  • High winds can topple trees or snap branches onto power lines.
  • Lightning strikes can damage transformers, substations, or utility poles.
  • Flooding from heavy rain can overwhelm underground systems and corrode electrical components.
  • Snow and ice add weight to power lines, pulling them down or causing poles to break under the pressure.

The power loss during storms can last for hours or, in severe cases, several days. Restoration crews work as quickly as they can, but the amount of damage determines how fast electricity is restored.

The Strain on Aging Infrastructure

Much of the US power grid dates back decades, long before today’s high energy demands and extreme weather patterns. Much of that infrastructure is overdue for upgrades. When outdated equipment fails, repairs take longer, and the chance of repeat problems rises.

The Climate’s Impact on Electricity

Climate change is worsening the strain on the aging power grid. Summers are hotter, which raises demand for cooling. Storms are stronger, which increases the likelihood of downed wires and damaged substations. And in states like New Jersey, hurricanes, thunderstorms, and nor’easters are simply a part of life.

This combination of old equipment and harsh weather has led to more frequent and prolonged power loss during storms. For families, it means losing air conditioning, heat, refrigeration, and internet for an indeterminant amount of time. For businesses, it can mean halted operations and costly downtime.

Efforts to Strengthen Grid Resilience

In the face of more severe weather and rising electricity demand, improved grid resilience has become an urgent priority. State and federal leaders are in the process of modernizing the grid.

For example, new rules have been approved in New Jersey to speed up the connection of renewable energy and storage projects. These measures aim to improve reliability, lower costs for customers, and strengthen defenses against storm damage. Utilities are also investing in technology like digital and AI monitoring to help make the grid more flexible and responsive.

Even with these changes underway, updating the grid will take years. Until then, residents and businesses need reliable backup solutions that keep the power flowing even when the grid goes down.
