I believe that Brazil gives a good case study on the subject. The whole sector used to be state-owned and electricity used to be more expensive and outages a very regular thing. Currently, some parts of the country have private generation and transmission with targets sets for the number of planned shutdowns, outages and inspection set by the regulatory agency. The private companies are light-years ahead on any metric that you can think of. The parts of the sector that are still public-owned are legendary on their wastefulness and lack of accountability.
