Winter Grid Operation in Remote Areas – Distance and Weather Challenges

As temperatures drop below zero and snow blankets Sweden's remote regions, grid operators face one of the year's most demanding periods. Long distances, limited accessibility, and winter weather create unique challenges for operating and maintaining critical infrastructure.

When Storm Johannes swept across Sweden on December 27th, nearly 30,000 customers lost power, primarily in Jämtland and Västernorrland. Fallen trees blocked roads and hampered emergency responses. The Swedish Transport Administration and police issued a joint warning: "Don't venture out on the roads unnecessarily, or be prepared to get stuck." For grid operators, the situation became critical – not only due to extensive damage, but because many affected areas were extremely difficult to reach.

Digital monitoring doesn't prevent storms or fallen trees. But it provides operators with information to assess: do we really need to go out now, or can this wait? By seeing the actual condition of components remotely, operators can make better-informed decisions about when the risk of sending personnel is justified.

In Sweden's sparsely populated areas, it can take hours to reach a transformer station or switching station in response to an alarm or suspected fault. Roads that haven't been cleared, icy conditions, and limited daylight transform what would be a routine inspection in summer into a hazardous expedition.

For grid operators, this means every unnecessary callout becomes costly – in time, resources, and risks to personnel. At the same time, a real fault can have serious consequences if not detected in time. When roads are impassable, digital monitoring becomes essential for knowing where resources are needed.

Traditionally, operating power grids in remote areas has been about reacting to faults when they occur. Reactive work will always be part of operations – acute faults must be handled. But when accessibility is limited in winter and every callout involves risks, the need for better decision-making data becomes clear.

Modern IoT solutions and continuous monitoring make it possible to complement reactive work with proactive analysis. By tracking trends in temperature, load, and other parameters, operators can plan maintenance for periods when weather permits – and most importantly: identify which faults actually require callout and which can wait.

For grid companies with extensive rural networks, the ability to optimize maintenance and callouts becomes critical during winter months. Digital monitoring provides real-time visibility across the entire network – whether the nearest station is 50 or 500 kilometers away.

The winter image of a lit road through snow-covered forest is beautiful. But for those responsible for power grid infrastructure, winter is about having better conditions to make the right decisions when circumstances are at their toughest.
