We have that pricing as well but we also pay a dynamic cost to be connected to the grid. When the power is cheap the grid cost is the biggest part of the bill.

With regards to our Hydro power: since the europeans took over we tap all of our water reserves and sell it cheap to the continent ever since the large acer cables came. When the winter comes our reserves are low and we buy expensive power back. It's been like that for a few years now. The government are looking into making a subsidy or tax break or something to compensate but EU is blocking it as market manipulation or something like that. It sucks ass.
