PG&E announced today that, in 2013, the 15 million people served by the utility experienced the fewest minutes without electricity in company history. The just-released numbers for 2013 show that PG&E continues to make significant progress in safely delivering reliable service that benefits homes and businesses throughout northern and central California.
In 2013, not only did the average duration of a service interruption for a PG&E customer fall to an all-time low, but customers also experienced the fewest service interruptions in company history. Customers have seen a 40 percent improvement in the average duration of a service disruption and a 27 percent improvement in the number of customer interruptions since 2006.
“Thanks to the significant work that has been done to upgrade and modernize electric facilities throughout our service area, PG&E’s customers are experiencing the most reliable service in our company’s history,” said Geisha Williams, executive vice president of Electric Operations for PG&E. “We are committed to build on this success, to further strengthen our operations to provide our customers with the safe, reliable and affordable electric service they expect and deserve.”
PG&E and other electric utilities measure the overall reliability of their systems using two primary indices defined by the Institute of Electrical and Electronic Engineers (IEEE). The System Average Interruption Duration Index (SAIDI) measures the number of minutes over the year that the average customer is without power. The average PG&E customer was without power for 117 minutes in all of 2013, a reduction from 196 minutes in 2006. The System Average Interruption Frequency Index (SAIFI) measures the system-wide frequency of power interruptions per customer. The average customer experienced 1.07 power interruptions in 2013, compared to 1.46 in 2006.
In order to ensure that customers receive the safest, most reliable and affordable service possible, the company is focused on continuous improvement. These improvements in service were due in part to the utility’s investments in several key projects, including:
