1 Although PG&E ran into construction challenges in 2011, we have implemented process improvements to strengthen our performance moving forward. This activity is part of a multi-year program and PG&E remains on track to meet our longer term goal for valve automation.
2 Refers to pipeline reconfiguration to accommodate insertion of inspection tools or “smart pigs.”
3 Beginning in 2012, PG&E’s targets will include planned outages to provide a more complete view of our electric reliability performance.
4 Each year, and for a variety of reasons, a statistically small number of PG&E’s approximately 20,000 employees are unable to attend a training session. To earn a Green assessment for this metric, PG&E’s result must fall within 1 percent of the target.
5 Represents the percentage of management employees who certified that they had read, understood and would comply with the Employee Code of Conduct. To earn a Green assessment for this metric, the result must fall within 1 percent of the target. Union-represented employees received electronic reminders or briefings from supervisors about the code.
6 Refers to the percentage of bills that are not adjusted after being mailed to the customer. Each year, a very small percentage of bills must be estimated, largely due to intermittent connectivity (similar to a cell phone temporarily losing its connection).
