Electricity costs for holiday homes

[Stateside Canary]

I have been reading the posts on the cost of electricity in France under a couple of other topics here with great interest, but most refer to homes which are occupied full-time.

Until now we have been paying under Option Heures Creuses with EDF for our cottage, but we were recently told by a friend living in France that Option base would be much cheaper under our circumstances, as the standing charge is much lower. Apart from a couple of longer holidays each year, we hope to visit the cottage about once per month for a day-trip, with the occasional overnight stay, and it will not be let out to anyone else. We have a small stone property with 3 bedrooms, a living room (with wood-burning stove), kitchen and small bathroom, and apart from lighting and the usual kitchen appliances (oven, kettle, iron, small microwave, fridge), a water heater, and a small electric radiator in our bedroom, nothing much bigger than a portable CD player and DVD player will be used. We have a 9kw supply, and there are usually only 2 of us there.

I am waiting for a reply from EDF giving advice on which tariff would be cheapest for us, but in the meantime would be glad to know if anyone has any experience of electricity costs for a small property occupied on a limited basis such as ours, especially as some members seem to think that the advice from EDF tends to be a little biased!

Thanks.
