Rate setting is a slow process and they are still working this through - I haven't kept up on it lately, but I believe this will be finalized late this year. Those with residential NET metering are supposed to be grandfathered on the current time of use time periods for a period of five years (not sure if it's from the start of the new TOU period, or if from the interconnect date, but probably the latter).RegGuheert wrote:(I'm not quite sure why SDG&E's TOU rates do not yet reflect this reality.)
Thanks, guys! It's good to hear they are addressing this.Randy wrote:A proposed decision on the TOU issue was released on May 18. Comments are due in a couple of weeks...

That makes good sense. The market is moving in a direction which will make personal storage systems like Tesla's Powerwall and Enphase' AC Battery more attractive. Advances in the technologies behind those products will also help.Randy wrote:Highlights of the decision include:
* Adopts a five-month summer season (June-October)
* Adjusts base TOU periods so that the on-peak period is 3-9pm daily
* Extends super off-peak to be midnight to 6am weekdays, adds 10am-2pm super off-peak in March and April. Also extends super off-peak from midnight to 2pm on weekends.
TOU pricing will be a continuously-moving target. Eventually I expect "super-off-peak" times to occur in the middle of the daytime. We will need to start moving to some form of BEV-net-metering before we get to that point in order to encourage daytime charging by not penalizing employers unduly. It will also reduce the amount of battery oversupply that will occur.
