The California ISO (Independent System Operator) is a nonprofit organization responsible for managing the state's electric grid. It ensures that electricity supply meets demand in real-time, facilitating the flow of power across the grid while maintaining reliability and efficiency. The ISO also oversees the wholesale electricity market, allowing various energy producers to sell their power. In addition to grid management, the California ISO plays a crucial role in integrating renewable energy sources, such as solar and wind, into the energy mix. This helps California meet its ambitious climate goals and transition to a more sustainable energy future.
