Climate change is no longer just a distant threat looming in the future; it is our reality today. With hotter days, more severe storms, wildfires, and other extreme weather events becoming more common, it is clear that we must adapt to these changes. However, while we are evolving and adjusting to the new normal, our infrastructure is struggling to keep up.
One area where this lack of preparedness is particularly concerning is in the energy sector. The Midcontinent Independent System Operator (MISO), which oversees the bulk electric grid across the central United States, has never before considered how climate science should inform its planning and transmission system investments. This is alarming, considering that MISO is responsible for supplying power to 45 million consumers across 15 states.
As a climate scientist, it was surprising to learn that I was the first to address the importance of climate change resilience in MISO’s operations. The reality is that extreme weather events are already impacting our energy systems, and without proper planning and investments, the consequences could be dire. From more intense heatwaves to severe storms and hurricanes, our electricity grid must be able to withstand these challenges.
It is crucial for entities like MISO to take into account the findings of climate science when planning for the future. By understanding how climate change is affecting weather patterns and increasing the frequency and intensity of extreme events, we can better prepare our infrastructure to ensure a reliable and affordable supply of electricity.
One example that highlights the importance of climate resilience in our energy systems is the severe storm that hit Madison, Wisconsin in June 2022, leaving hundreds of thousands without power during a heatwave. This is just one of many instances where our grid has been unprepared for the impacts of climate change.
To address these challenges, the Union of Concerned Scientists has developed a report titled “Keeping Everyone’s Lights On: How to Build an Equitable, Climate-Resilient Power Grid.” This report outlines recommendations for increasing the resilience of the US power system to climate change and ensuring that all communities are equally valued in decision-making processes.
In order to achieve a climate-resilient power grid, collaboration between climate scientists, electricity system researchers, system planners, and decision-makers is essential. By working together and utilizing fine-scale climate projections, we can better understand the risks posed by climate change and take proactive measures to mitigate them.
It is clear that the threats to our electricity grid from climate change are growing more serious by the day. It is imperative that we urge our legislators to prioritize climate resilience in our energy infrastructure and ensure that the systems that keep our lights on are prepared for the challenges ahead. Our safety and well-being depend on it.
