One of the attached articles states that there is no connection between the privatisation of electricity and rising prices. And yet it also says that the private sector was engaged to build and provide the current generation of electricity and was responsible for possible cost overruns and in return was given expensive 20 year contracts to produce the power. So it seems that it was acknow;ledged that there would be cost overruns(inefficiency) and the companies were rewarded for that by too generous long term contracts. Bottom line; get the private sector out of publicly necessary services. Read David Cay Johnston's book "The fine print" to see how you are likely getting screwed by power companies.
