Managing the solar eclipse
On Monday, April 8, 2024, a partial solar eclipse will cross over the western United States, impacting both grid-connected and behind-the-meter rooftop solar generation in the California ISO balancing authority and its real-time Western Energy Imbalance Market (WEIM). With the electricity grids in the West more interconnected than ever, the CAISO has studied the potential effects of widespread solar generation loss during the three-hour eclipse, identifying risks and solutions, and coordinating with WEIM participants, the Reliability Coordinator West (RC West), and other balancing authorities and stakeholders to maintain grid reliability.
