I'm going to be doing a remodel and plan on purchasing a Tesla once the remodel is done, assuming I don't blow my budget. Right now I'm trying to decide if I want to install 1 or 2 meter's for PG&E. At this point, I'm considering the cost of the additional meter installation marginal to the grand scope of the remodel.
The confusion occurs when I drilled down into the two EV rates offered by PG&E. My assumption was that by installing two meters and using the EV-B rate, you would get a better rate since PG&E knows you're only using this for your EV. Turns out my assumption was wrong, or at least partly wrong. Both peak and part peak rates are lower in B than A, however, off peak is at least 50% higher after 130% of baseline.
Based on what I see, it's never a bigger savings to be on EV-B as you will charge your car at a higher rate, and this will be the bulk of your energy usage. I also tried playing around with the PEV calculator (http://www.pge.com/cgi-bin/pevcalculator/PEV) to see where EV-B creates a savings and it seems the calculator does not want to do it. If you select E-1 it drops the monthly kwh to 363 ($123/M) while on E-6 it jumps to 1101 ($353/M). If the calculator is correct, I should just use the EV-A plan and call it a day.
Am I missing something or is this correct?
