Utilities estimated that about 560,000 customers were affected yesterday,

However, Southern California Edison's burden was considerably lighter

Karen Shepard-Grimes, a spokeswoman for the Southern California utility, said 
only about 50,000 customers went without power, compared with nearly 440, 000

and Pomona. 
"We're not in the business of turning customers' lights off," Shepard- Grimes 
said. "We're in the business of keeping lights on." 
In PG&E's case, things were tougher because low rainfall means that less 
power is currently available from dams throughout the Pacific Northwest. 
Ron Low, a spokesman for the utility, said blackouts were experienced by PG&E 
customers from Eureka to Bakersfield. 
"Our goal was to carry out the ISO's order with minimal impact on customers, 
" he said. 
For its part, San Diego Gas & Electric said about 75,000 customers were 
darkened. 
Yesterday's blackouts began with PG&E customers in Block 12 and halted midway 
through Block 14. Customers in each block -- defined by power circuits rather 
than geography -- typically will lose power for about 90 minutes before the 
service interruption "rolls" elsewhere. 
Some cutoffs can last more than two hours, however, because of technical 
problems switching individual blocks on and off.
