I have found comments and threads on the SDGE proposed rate increase, and estimates of net average cost increase, but no details on exactly what tariff increases SDGE is proposing. The only EV surcharge comment I could fine was someone who was contemplating charging his Leaf during peak solar production so the power would not go through SDGE's meter at all. This of course would be silly from a system standpoint - the grid would get less peak power back when it needs it during peak A/C usage.TonyWilliams said:look what SDGE has proposed for solar powered homes... you're one CPUC decision away from a special "surcharge" for home EV charging.
Right now SCE charges a negative $.0254/kWh delivery charge for on-peak Summer TOU Level 1. In Oct I was charged $2.62 to send 103 kWh to the grid during peak TOU Level 1 (- times - delivery). At Level 2, this delivery charge switches to positive $.314/kWh and I received a credit of $12.56 for generating 40 more kWh. I have no explanation for why the sign changes between Level 1 and Level 2. For both Level 1 and Level 2 the generation charge is a positive $.259/kWh, so I still get a credit for all net generation. If SDGE is proposing a similar modest charge for "reverse delivery" I could live with that.
My understanding is that presently residential solar represents less than 1% of total power generation in CA, and much less nationally, so it would seem that SDGE's concern about being stuck with stranded excess generation and distribution investment is a little premature. Perhaps residential solar is growing at a much higher rate than the state-wide average in SDGE's territory.
I would appreciate any links that give more details on SDGE's proposal, because I was told by a SCE employee that they definitely were thinking along the same lines as SDGE.
