The California Independent System Operator (CAISO) is a nonprofit organization responsible for managing the electricity grid in California. It ensures that electricity supply meets demand in real-time, facilitating the flow of power across the state. CAISO also oversees the wholesale electricity market, allowing various energy producers to sell their power. In addition to grid management, CAISO plays a crucial role in integrating renewable energy sources, such as solar and wind, into the energy mix. By promoting clean energy initiatives, CAISO aims to enhance the reliability and sustainability of California's electricity system while supporting the state's environmental goals.
