Paraguay relies almost solely on hydroelectric power to meet its energy needs. The Itaipú Dam, completed in 1984, has the world's second largest power-generating capacity: 13.3 gigawatts. The dam is located on the Paraguay River, and Paraguay and Brazil evenly share the ownership, operation, and electricity generated. Additionally, Paraguay co-owns another major hydropower plant, Yacyretá, with Argentina. Paraguay uses only a small portion of the energy it generates through Itaipú and Yacyretá. In 2002 Paraguay generated more than 48 billion kilowatt-hours of energy. It consumed only 2.5 billion kilowatt-hours while exporting 45.9 billion kilowatt-hours. Paraguay will have even more hydroelectricity to export when planned new turbines are installed at Itaipú and the Yacyretá dam is fully completed. In 2007 electricity production rose to 70 TWh, and exports reached 64 TWh which put Paraguay in second place worldwide as an exporter of electrical power . Paraguay has no oil reserves; it relies on imported oil to meet its limited need for oil-produced energy. The Paraguayan government owns Petróleos Paraguayos, which is responsible for all distribution of oil products. The state accepts bids from international oil companies, selecting a few companies annually to meet the country's demand. Presently, Paraguay does not produce or consume natural gas, but consumes LPG imported mainly from Argentina.
