Could indeed be $0.16 kwh, also the article mentions a 70amp supply, whereas in the UK the Tesla charger is 30amp. Just dawned on me as I was writing this, that Canada uses 110v. So everything needs a higher current, 30amp here is around 7.4kw, so you would need 70amp in Canada for the same kw charge rate. So any figures quoted are way off base for the UK.
