Weather insights for power grids

The integration of local, accurate and timely weather and environmental measurements into Dynamic Line Rating systems transforms how power grids are managed. It allows for a more adaptive, efficient, and safe distribution of electricity, which is crucial for meeting varying demand without compromising system integrity.

Atmospheric parameters that affect Dynamic Line Rating include wind speed and direction, ambient temperature and solar radiation. These insights empower decision-makers to drive production planning and output efficiency, enhance the capability to forecast supply and demand, and improve safety.

Key applications:

• Maximizing transmission capacity
• Reducing curtailment and congestion (span-level, line section aggregation)
• Understanding and anticipating the impact of wind, temperature and sunlight on capacity 

Severe weather events like storms, high winds and solar radiation can cause significant damage to power infrastructure and risk crew safety. Timely and precise environmental measurements empower operators to prepare and respond effectively, minimizing downtime and restoring power faster.

Key applications:

• Enhancing grid resilience through weather-based risk management strategies
• Visualizing weather data to assess grid vulnerabilities
• Optimizing power generation and distribution
• Load forecasting and demand response

Actionable weather insights can enhance operations at every stage of a weather event:

• Before – assessing risk
• During – determining level of safety for dispatching crew, especially if high winds or lightning is presentAfter – analyzing an outage and planning future responses
