Market development has gone through a trial-and-er-ror approach that included a government decision in 2000 to build 49 power plants with a total capacity of 14,000 MW. This belated and unrealistic decision was taken when the risk of a power shortage had become acute. That plan was dissociated from the existing hydro system, and was eventually dropped, but not before a number of plants had been built, including several open-cycle inefficient plants.
