The prolonged cold weather during Winter Storm Fern tested the limits of the natural gas system, particularly in regions with infrastructure constraints. The Northeast and Mid-Atlantic areas experienced price volatility due to limited pipeline capacity, highlighting the risks of supply shortages during peak demand. The report warns that without further investment in infrastructure and winterization, future storms could pose greater challenges, including potential service disruptions and increased costs for consumers. Additionally, the study emphasizes the importance of protecting critical natural gas infrastructure during electric grid emergencies to ensure reliability.
