Turbo3 said:I have the old E-7 PG&E TOU rate and last time I looked at it saw no advantage in having a second meter.
First, I have excess money in my account (around $175 to $200) each true-up period and have to give it all back to PG&E each year. If I have a second meter then there would be no way to use this free power.
Second, for E-9 rates there is a daily meter charge each month added to the super off peak rate. When you added that in you need to use a lot of power to see a big saving between my E-7 off peak and E-9 off peak. For example if you drive 800 miles per month at 4 miles per kWh then you use 200kWh. For a 30 day month the meter charage is 30 x $0.21881 = $6.56/month. E-9 Rate A summer is $0.5294/ kWh so 200 kWh cost you $10.59. Add in the meter charge takes it to $17.15 for a real cost of $0.085762/kWh compared to my E-7 $0.09273/kWh. Less than a cent difference per kWh and E-7 lets me charge at off peak starting at 6 PM until noon the next day. (For Winter rates it is even less of a difference. Numbers from 3/1/2011 Rate table.)
When I installed my solar I paid a one time charge for the TOU meter so I have no daily meter charge. E-7 rate closed back in 1/1/2008 so if you don't already have it you can't get it.
So if anyone with E-7 is thinking of getting a second meter for the E-9 rate I would like to know how they get a cost savings.
DId I miss something but my arithmetic shows $0.5294/ kWh x 200 kWh cost you $105.9.(not "$0.5294/ kWh so 200 kWh cost you $10.59"). I presently have E-1 and am wondering if there is a cost savings going to E-9 (don't have solar), now that I have a LEAF.
