If baseline is 300 kWh and you use 400 kWh (net) and the credit is 10 cents you get a line item that says credit $30
The rest of the tiers are charged as used. You can net them in your head any way you like.
Yes, I agree. This was hard for me to get my head around as well. Once you exceed your baseline allocation in net usage, your SOP incremental rate goes to $.11/kWh, not $.01/kWh. That is still awfully cheap for California, although it is nothing special or even high for states burning coal.
TOU D-A worked reasonably well for me all last year, except Aug and September, where I just could not wait for 8pm to power up the A/C. However, on less extreme days I broke even on OnPk, generating as much after 2pm before sundown as I consumed with A/C after dark before 8 pm. On weekends I accumulated net credits for OffPk in the afternoon to use during the week.
Prior to 2015 TOU DT-EV with its 10am to 6pm OnPk window was much more generous for me.
Even at $.11/kWh, charging the Tesla after full day excursions really broke the bank for me last year, so I am hoping to install a few more solar panels. The good roof is all gone, but I have some eastern exposure that is will generate about 4 hours per day, 9am to 1pm. In the winter, the angles are shallow, but in summer I will get decent Offpk production in the morning.
Last September, in the middle of the heat wave, I also installed a 3 kW ductless mini-split Mitsubishi inverter heat pump system for the 3 rooms I use the most. I expect it will save me a lot next summer. Right now I am running the heat pump in reverse to reduce my natural gas usage (a la Porter Ranch), but getting serious with this will have to wait until I get the extra solar.
