Should Per\u27s State-Run Energy Companies Play a Bigger Role?

Peru\u27s state-owned energy companies may play a greater role under the administration of newly-inaugurated President Ollanta Humala, Peruvian Minister of Energy and Mines Carlos Herrera said last month, according to Reuters. Herrera added that the idea would be for state companies, such as Petroperú and Electroperú, to have a greater role in state management and the general idea is for the capital to be private.
