Keeping the Lights on - Resilient Power Networks

Climate change continues to be a high priority across all industries, particularly the energy sector. As the frequency and severity of natural disasters increase, so must the ability of the electrical power grid to withstand and recover from disruptions in order to maintain essential functions and services.

These severe weather events are among the leading causes of large-scale power outages globally. According to the World Meteorological Organization, the number of weather-related disasters has increased by a factor of five in the past 50 years. It is essential for power grids to be able to adapt and recover quickly to minimize the impact on global economies and communities and ensure the continuity of essential functions and services.

Most outages will damage or impact generation sites, large transmission lines, or substations causing widespread disruption to essential services and economic activity. By planning and executing a network to improve grid resilience, while the impact is not completely mitigated, the time taken to restore power and minimize customer impact is significantly reduced.
