According to the site above a block heater using:
1000 kw for 30 days @ 12 a day will use 360 KWh for $54.00 p/month
600 kw for 30 days @ 12 a day will use 218 KWh for 32.40 p/month.

This site talks about some of the problems of charging cars.
“When plugged into a standard 120-volt socket, the electric car will draw 1,500 watts. By comparison, a medium-sized air conditioner or a countertop microwave oven will draw about 1,000 watts."
At this rate, according to the calculator it would cost about $81.00 for a month of similar use as the block heaters, in Edmonton. We also have plug-ins at most offices and homes.
What also needs to be considered is that at most of the Condos here, at least, parking is not included in condo fees but a separate charge on top of rent/mortgage, utilities etc.
What surprises me is that they don't already have separate electric metres for each condo already. There are very few condos or rental units here that don't already have this, unless the building is very old.
