A widespread power outage affected Solano County, California, on Tuesday, leaving more than 9,000 customers without electricity before service was gradually restored. The outage was first reported shortly before 5 p.m. on May 26, 2026, and initially impacted customers in Fairfield, Rio Vista, Suisun City, Vacaville, Vallejo, and unincorporated parts of Solano County.
At the peak of the outage, 14,645 customers were reported without power. By 5:50 p.m., the number had dropped to 9,755 customers, indicating that crews or utility systems had begun restoring service in parts of the affected area. Later, according to the outage map, the number of customers still without electricity had fallen sharply to 158 by 7:26 p.m.
The outage disrupted homes and businesses across multiple communities in the county, though no cause was included in the report. The incident highlighted the large geographic reach of the disruption, which extended across both city centers and unincorporated areas. Residents in the affected communities experienced an evening without power as utility crews worked to bring service back online.
The gradual reduction in outage numbers suggests restoration efforts progressed through the evening, with the majority of affected customers regaining electricity within a few hours. The report did not specify whether any emergency services, traffic signals, schools, or other critical infrastructure were impacted.
Solano County includes a mix of suburban, residential, and commercial areas, so outages of this size can affect a broad range of daily activities. Refrigeration, lighting, communications, and home cooling or heating systems may have been interrupted for many households and businesses during the outage period.
By late evening, the outage had largely been resolved, with only a small number of customers still listed as affected. The event stands as a brief but significant utility disruption for residents across several cities in Solano County on May 26, 2026.
