Winter Grid Reliability Starts Now: How Utilities Can Prepare Critical Assets for Extreme Weather

Winter reliability starts before the first freeze. For electric utilities, preparing for winter weather is not simply about watching the forecast. It means evaluating critical grid assets, identifying potential vulnerabilities, and making sure the right equipment and resources are available before extreme conditions arrive.

Recent winter events have reinforced why proactive planning matters. A recent review from the Federal Energy Regulatory Commission (FERC) and North American Electric Reliability Corporation (NERC) found that the bulk power system performed better during extreme cold events in early 2026 than during previous major winter storms. Even so, the findings continue to emphasize the importance of winter preparedness, accurate forecasting, fuel availability, coordination, and infrastructure readiness.

For utilities across the United States, the message is straightforward: winter grid resiliency should be part of the plan long before temperatures drop.

Why Winter Weather Matters for Grid Reliability

Extreme cold can create a combination of challenges for electric utilities.

As temperatures fall, electricity demand can increase as customers rely more heavily on heating systems. At the same time, severe weather can create difficult operating conditions for generation, transmission, and distribution infrastructure.

Potential challenges include:

• Increased electricity demand

• Unexpected generation or equipment outages

• Stress on transformers and other critical equipment

• Difficult field conditions for utility crews

• Supply chain and equipment availability challenges

• Increased pressure to restore service quickly

  
  

These challenges can compound one another. When multiple pieces of the system are stressed at the same time, utilities have less room to respond to unexpected failures.

That makes proactive asset management and winter preparedness especially important.

Start With Your Critical Grid Assets

One of the most important steps utilities can take before winter is to evaluate the condition and readiness of critical equipment.

Utilities should consider questions such as:

Which assets are most critical to system reliability?

What condition are those assets in?

Which equipment is being actively monitored?

Are there aging assets that may require additional attention?

What equipment would be difficult to replace if it failed during a winter event?

Are replacement and emergency equipment needs already identified?

These questions can help utilities move from reactive maintenance toward a more proactive approach to grid resiliency.

Transformer Monitoring Can Provide Greater Visibility

Transformers are among the most critical assets in the electric grid, and understanding their condition can help utilities make better maintenance and replacement decisions.

Transformer monitoring solutions can provide utilities with greater visibility into equipment performance and operating conditions. That information can help identify potential issues, support maintenance planning, and provide valuable data for managing asset life.

For example, APT offers digital transformer temperature control and agnostic sensor solutions designed to work across monitoring systems. Its technology can aggregate information from multiple sensors and monitoring systems, giving utilities greater visibility into transformer conditions.

For utilities preparing for winter, monitoring is one piece of a larger asset-management strategy: know what is happening with critical equipment before an unexpected event forces the issue.

Evaluate Aging Transformer and Substation Equipment

Winter preparedness also provides an opportunity to look at the bigger picture.

Are transformers approaching the end of their expected service life? Are there aging components that should be evaluated? Are critical substation assets adequately supported?

Utilities can use pre-winter planning to identify equipment that may need:

• Inspection

• Maintenance

• Replacement

• Upgrades

• Additional monitoring

• Emergency contingency planning

  
  

Having these conversations early can help utilities avoid making critical equipment decisions in the middle of an emergency.

NexGen Utility Sales works with utilities and electrical equipment manufacturers to help identify solutions for transformer, substation, transmission, and distribution applications.

Our linecard includes solutions across critical utility equipment categories, giving utilities access to a network of manufacturers for both planned projects and emerging equipment needs.

Equipment Availability Is Part of Resiliency

Grid resiliency is not only about preventing equipment failures. It is also about being prepared when something does go wrong.

If a critical transformer, switchgear component, or other piece of electrical infrastructure fails during an extreme weather event, equipment availability can directly affect restoration timelines.

That makes it worthwhile for utilities to consider:

• Which critical components have long lead times?

• Which assets have limited replacement options?

• What spare equipment is already available?

• Which manufacturers can support emergency needs?

• Are there equipment alternatives that should be identified in advance?

  
  

Building manufacturer relationships and understanding available equipment solutions before an emergency can give utilities more options when time matters most.

Winter Preparedness Is Part of Grid Resiliency

There is no single piece of equipment or technology that makes a grid resilient.

Grid resiliency comes from a combination of planning, asset management, monitoring, maintenance, equipment availability, and strong industry relationships.

The goal is not to predict every possible winter event.

The goal is to make sure the utility is prepared to respond when conditions are more challenging than expected.

Frequently Asked Questions:

What can utilities do to prepare the grid for winter?

Utilities can prepare by evaluating critical assets, monitoring equipment condition, identifying aging infrastructure, planning maintenance and replacement needs, and confirming equipment availability before extreme weather occurs.

Why are transformers important for winter grid reliability?

Transformers are critical components of the electric grid. Monitoring their condition and proactively addressing maintenance or replacement needs can help utilities reduce the risk and potential impact of equipment failures.

What is grid resiliency?

Grid resiliency is the ability of the electric power system to withstand, adapt to, and recover from disruptions such as extreme weather, equipment failures, and other unexpected events.

How can utilities improve winter preparedness?

Utilities can improve winter preparedness through proactive asset management, equipment monitoring, maintenance planning, emergency response planning, and relationships with equipment manufacturers and suppliers.
