We moved into our current house November 2015, we literally doubled our floor space, added a pool and central AC to our family home that we bought. We have been on the basic 3 tier plan, now that I have the MS, I need to make sure we are on the right plan through So Cal Edison. We are a family of 2 adults and 2 small children, my wife and I work full time and we are pretty much out of the house from 7am - 6pmish (FYI: we have multiple layers of security including neighbors that are home all day) so our usage weekdays is primarily early in the mornings and later in the evenings. For some reason we always assumed that we were on a TOU plan so we instinctively tried to shift energy use to be on during the late night, like our pool pump, I currently have it set to run from 12am - 5am. Today, I called SCE and switched to the TOU-D-B which is: TOU-D Option B (TOU-D-B) TOU-D-B has three different time or “peak” periods and associated pricing. This rate option has generally lower peak prices There is no baseline credit on this rate option The daily basic charge is $.54 per day This rate option is generally attractive to high usage customers, with monthly usage of more than 700 kWh Close peak hours and pricing Hide I get home around 7pm and right now have to charge the car with the basic 5-15 plug because I need to upgrade my panel from a 100amp to a 200amp service. I should have that complete hopefully by the end of this month at which time I will be getting a 14-50 on a dedicated circuit installed, then eventually going solar. Currently I'm charging the MS all night and leave around 7am, so its plugged in anywhere from 10-12 hours nightly into the early mornings. Our current bill is anywhere from $111 - $160 per month, I've calculated about another $50-$75 more a month just for adding the MS. For those in the So Cal area that have Edison, have you changed to a TOU plan after you got your Tesla? Can anyone with a similar situation shed some light if changing to a TOU saved you money or did it make your bill go up? T.I.A.
