I wonder how low can industrial customers get their power. As far as i read they can get direct contracts with the electricity power exchange. Then i see the prices there:
http://www.eex.com/de/ Its 32€/MWh. That should be around $3.5 Cent... I wonder how low this could get. In germany the power costs at the exchanges are dropping everytime too because of the huge amount of solarpower coming in... only the big suppliers of power raise the price and claim the reason is the costly solarpower. Clear lie to keep their atomic mills. But when one would have access to the power exchange you wouldnt need to buy from them.
But its only a thought... its probably too hard to achieve.
Sometimes individual non-industrial customers may get direct contracts with the power companies but it will cost extra if it requires investments in the infrastructure and only for high usage.
As for Germany, it doesn't lie in the middle of the Sahara desert, using solarpower is (especially in that part of the world) more expensive unless one relies on government subsidies.
Of course the solar power costs are getting lower over time, as the technology is becoming more common, manufacturers are finding ways of making it cheaper and more efficient.
As for that graph above, price electricity in Poland is of course dependent on the place but it is generally more expensive, and definitely more expensive than France (I have lived in both countries, most of the electricity (~90%) is derived from nuclear power stations, in Poland there are none).
