Extreme weather events are having a significant impact on the power grid, especially as renewable energy sources like wind and solar become more prevalent. A groundbreaking study conducted by the National Renewable Energy Laboratory (NREL) investigated how this changing landscape of extreme weather can influence the operation of the power system.
The study, led by NREL researchers, delved into the potential challenges posed by extreme weather events on the U.S. power system, particularly in scenarios where wind and solar energy play a substantial role in the energy mix. This analysis aimed to redefine our understanding of what constitutes “extreme weather” and its impact on grid reliability.
Marty Schwarz, an NREL power systems engineer and one of the report’s coauthors, highlighted the study’s dual focus on assessing the operational challenges of integrating higher levels of wind and solar energy and redefining the concept of extreme weather based on its effects on grid operations.
To conduct the study, analysts utilized NREL’s ReEDS model to simulate the evolution of the power system for the years 2024, 2036, and 2050, with renewable generation levels ranging from 17% to 65% of annual demand. Historical weather data and records from 2007 to 2013 were also analyzed to identify high-impact weather events and planning challenges that could affect grid operations.
The findings challenged traditional perceptions of extreme weather, revealing that wind and solar power can remain available during extreme weather events due to the unique meteorological conditions they exhibit. While events like heat waves or cold fronts can increase grid load, they often coincide with conditions favorable for renewable energy generation.
The study’s results suggested that the most concerning weather events for future grid operations may differ from those prioritized today. Analysts identified specific combinations of weather conditions with low wind and solar resources as potential challenges for power system reliability.
The study’s insights have far-reaching implications for planners, policymakers, and researchers as they navigate the transition to a more renewable energy-driven grid. By considering the impact of extreme weather on grid operations, stakeholders can better assess the resilience and resource adequacy of future power system infrastructure.
Looking ahead, the researchers plan to expand their analysis to encompass a wider range of weather scenarios and account for the influence of climate change on weather patterns. By gaining a deeper understanding of extreme weather events in the context of renewable energy integration, the study aims to inform more accurate planning and enhance the reliability of tomorrow’s power system.
