I'm currently putting together a submission to the owners Executive Committee in my apartment building to get the HPWC installed, possibly with some kind of meter. As an alternative to metering I was thinking about offering a monthly or yearly estimated usage payment. I'm aware there may be some regulations against buildings charging for electricity usage without accurate metering, but I can't find anything specific to the ACT about that. The reason for not metering would be if the building doesn't want the additional administration burden of having to read the meter and bill me. Using brewster’s poll results I’ve made some pessimistic assumptions of 250Wh/km, driving 15000km/year all charged at home, and an electricity rate of $0.27/kWh (commercial rate from ActewAGL). Even with all the pessimism that still only comes to $1012.50, or $1164.38 if you add another 15% for charging losses and overnight drain. Does that sound at all correct, or have I missed something? Also in case my my building EC members aren't aware electric vehicles, does anyone know of a good 1 page background article I could include?
