SACRAMENTO (CBS13) – California ISO again issued and lifted a stage 2 emergency on Sunday after warning residents should prepare for rolling blackouts as temperatures and energy demand remained high.
California ISO made the stage 2 announcement just before 6:00 p.m. and said energy conservation would be critical to avoiding the outages. At around 8:30, that stage 2 declaration was lifted as California ISO said consumers conserving energy were able to prevent rolling outages for a second day in a row.

A flex alert was again issued for Monday from 3 p.m. to 9 p.m.
California ISO said the grid was experiencing a shortfall of about 4,000 megawatts.
On Saturday night, the agency said consumers did their part in conserving energy to avoid rolling blackouts, and on Sunday they called on residents to do the same on a day in which Sacramento, Stockton and Modesto all recorded record-high temperatures.
Earlier in the day, California ISO said the power system outlook on Sunday was “tight and constrained” and a flex alert was issued from 3 p.m. to 9 p.m.
California ISO advises setting A/C units at 78 degrees or higher, limiting the opening of refrigerators and other major appliances that are major users of electricity, and turning off unnecessary lights.
Pacific Gas and Electric also announced this weekend that 17 counties, including several around the Sacramento region, face potential Public Safety Power Shutoffs as “a potentially widespread, strong and dry offshore wind event forecasted to start Monday evening and continue through mid-day Wednesday” is heightening the risks of more wildfires.
