Self-Generation Incentive Program 8 Time of Use (TOU) Rate Requirements Update  Starting in January 2007, CSI customers are required to take electric service under applicable TOU tariffs  The CPUC is expected to issue a decision on June 7 th that would allow customers a choice between TOU and non-TOU rates until more solar-friendly TOU rates are developed  Customers who were required to take service under a TOU tariff will be allowed to switch to a non-TOU tariff and will receive a credit for any difference in charges  The Legislature is working on emergency clean-up legislation that will postpone the mandatory TOU requirement until more solar-friendly rates are developed 7
