Enter Your Question Title Here Do the energy companies have a 'built in' fiddle.

[diadem01]

As electricity has a tolerance variation of 220 - 240 volts would anyone know how this equates to the selling price per unit.

I notice that my electricity power is often apparently below strength at certain times of the day, the main meal periods of course ... but I'm wondering if the electricity companies could deliberately supply the lowest possible current strength yet continue to ring up the charges at the fixed price per unit.

Does it cost the supplier more or less, for example, to supply lower strength power.

I'm not too bright about things like this so I can't envisage all the potential for profiteering, if in fact that would be possible … but I'd bet someone in AB knows.

Domestic meters measure the number of units used. This is the product of Voltage x Current x time. You pay only for what you use.

Thanks, Scotman.

I tried to mark it as best answer … but nothing happened!

Perhaps because it is the only answer (apart from your own comment), so it is inevitably the best.

Marking it as Best Answer only shows up on your own thread, diadem - it doesn't show for us.
