AMADOR COUNTY (CBS13) – Power is back on for 35,000 people in both Amador and Calaveras Counties.

Pacific Gas & Electric says the outage began at 3:30 p.m. Monday affecting the cities of Jackson, San Andreas, Ione, Plymouth, and Pine Grove.

Both the Calaveras and Amador Sheriffs’ dispatch centers ran on generators during the outage. Sutter Amador Hospital and Mark Twain St. Joseph’s Hospital also ran on generators.

PG&E says the issues appeared to be caused by transmission and substation issues.
