In the movie National Lampoon’s Christmas Vacation, Chevy Chase plays Clark “Sparky” Griswold, who decorates his home with 25,000 Christmas lights. Comedy ensues as he tirelessly works to find the one burnt out bulb that’s prohibiting any of lights from coming on. The lights go live, he’s electrocuted (but survives) and the local power station has to kick into high gear to supply the power. The 1989 classic comedy is good fun and airs at this time of year.

Hey Jim, great points but they’re even more important than you write.
You might get electricity for around 6 cents a kWh in Ontario, but that’s only the generation cost. You also have to pay for distribution, which brings your real per-kWh cost well above 10 cents.
I haven’t detailed info handy, but I believe the real price (including distribution, line loss, debt retirement, and taxes) in any North American district will be well over 10 cents per kWh with the possible exception of Quebec. So that puts the 2-month 24-hour price over $400, even double that in many jurisdictions, which is significantly more than $260.
