When extreme heat affects the entire power system, utilities need weather intelligence that shows where operational pressure may emerge. Extreme heat is no longer a single operational problem for European energy companies. It can raise electricity demand, constrain transmission, reduce output from multiple generation sources, and move market prices. That convergence changes the nature of
As Americans celebrated the nation’s 250th anniversary of independence in 2026, utilities across the country were responding to a very different challenge. Extreme heat and thunderstorms left more than one million utility customers without power, according to The New York Times, prompting safety warnings across much of the Upper Midwest and the East Coast. The
Electrification, renewable generation, and cross-border interdependence are changing the operating environment for European TSOs and the assumptions behind reliable grid operations. For decades, European transmission system operators (TSOs) operated with relatively predictable generation sources, established demand patterns, and conservative operating assumptions. Those conditions are changing. Electrification is increasing demand, wind and solar generation are introducing
Summer planning used to be about preparing for the hottest day of the year. Today, utilities are preparing for rapid changes in electricity demand driven by extreme weather, changing customer behavior, renewable generation, and new large industrial loads. What Is Summer Load Volatility? Summer load volatility refers to rapid changes in electricity demand driven by
As renewable generation, electrification, and cross-border power flows reshape Europe’s grid, weather is becoming a critical factor in how TSOs manage congestion, maximize transmission capacity, and strengthen resilience. Europe’s transmission system is operating in a fundamentally different environment than it was a decade ago. Transmission system operators (TSOs) are balancing reliability, congestion, transmission capacity, reserve
Anyone who works in live events understands that weather can disrupt even the best operational plan. A thunderstorm delays gates. High winds create safety concerns for temporary structures. Extreme heat changes staffing, medical readiness, and attendee behavior. Even indoor events are affected through parking, ingress, transportation, and crowd flow. None of this is new. What
How NERC TPL-008-1 is changing weather intelligence and grid reliability planning. In April, a new phase of reliability regulation took effect for U.S. utilities, marking the beginning of formal enforcement of NERC’s extreme temperature planning standard, TPL-008-1. While the requirements will continue to phase in over the next several years, this milestone represents a meaningful
New DTN Report Finds Weather Decisions Peak 48 Hours Before Impact Weather decisions in the event industry are not made when forecasts become available. They are made when the cost of acting becomes clearer than the cost of waiting. New research from DTN, “Weather Risk in Event Operations: The Gap Between Forecasts, Decisions, and Outcomes,”
When tropical storms and hurricanes are churning in the oceans, you may be hearing them called Cat 2 or Cat 3 storms. What does that mean and how do meteorologists determine the number? It’s actually pretty interesting, but not a job for the faint of heart. Key Takeaways Hurricanes are categorized using the Saffir-Simpson scale
For many of us, the arrival of June signals the beginning of the summer season, and a return to warm weather and outdoor activities. But for those living along the Eastern Seaboard and the Gulf Coast, the arrival of June has more ominous undertones as it signals the onset of hurricane season.
