Rolling blackouts are temporary power outages that are intentionally implemented by utility companies to prevent the electrical grid from becoming overloaded. During periods of high demand, such as extreme weather conditions, these outages help to balance electricity supply and demand, ensuring that the grid remains stable and functional. Typically, rolling blackouts affect different areas in a rotating manner, allowing power to be restored after a set period. This strategy helps to minimize the impact on any single location while maintaining overall system reliability. Such measures are often necessary during peak usage times or when there are unexpected failures in the power supply.
