Società: Mighty River Power Limited

Mighty River Power Limited is a New Zealand electricity generation and electricity retailing company. It was formed from the breakup of the Electricity Corporation of New Zealand (ECNZ) in 1999 as a result one of the reforms of the New Zealand Electricity Market and corporatised to become a state-owned enterprise with its own board of directors and Ministerial shareholders. A state-owned enterprise from its founding, it was partially privatised by the Fifth National Government in May 2013, with the government retaining a 51.78 percent shareholding and the remaining 48.22 percent listed on the stock market. The company owns and operates the hydroelectric generating stations on the Waikato River as well as geothermal plants in the Taupo area, the gas fired (combined cycle) Southdown plant in south Auckland and the largely unused plant (Marsden A and Marsden B) at Marsden Point near Whangarei.
