lower its greenhouse gas emissions by enacting measures in its energy, forestry and wetland sectors. Uganda's greenhouse gas emissions per capita is 1.39 tons carbon dioxide, one of the lowest in the world. The country aims to reduce its carbon emissions by 22 percent by 2030. Hydroelectricity The country's hydropower potential is an estimated 2,200 megawatts. Poor maintenance during the politically unstable 1980s resulted in a drop in production at the Owen Falls Dam (now Nalubaale Power Station), at the mouth of the White Nile, from 635.5 million kilowatt-hours in 1986 to 609.9 million kilowatt-hours in 1987, with six of ten generators broken by the end of 1988. The 200 megawatt Kiira Hydroelectric Power Station, built adjacent to the Nalubaale Power Station, raised total production capacity to 380 megawatts. Between 2007 and 2012, the 250 megawatt Bujagali Hydroelectric Power Station was constructed as a public-private project, at a cost of approximately US$862 million. The consortium that owns the station includes the Aga Khan Fund for Economic Development, SN Power (a subsidiary of the Norwegian Investment Fund for Developing Countries), and the government of Uganda. Bujagali Energy Limited is a special-vehicle company created to run the power station on behalf of the shareholders. In October 2013, construction of the 183 megawatt Isimba Power Station began, approximately downstream of Bujagali, at a budgeted cost of approximately US$590 million, as a public enterprise with funding from the Export-Import Bank of China. Commissioning was planned during the second half of 2018. However, construction was completed in January 2019, and commercial operations began in March 2019. Also in 2013, work on the 600 megawatt Karuma Power Station commenced at a budgeted cost of about US$2 billion, including US$250 million to build the high-voltage transmission lines to evacuate the generated power. Completion was planned for late 2018. However, a more realistic completion date is in late 2019 or early 2020. , about six operational mini-hydropower plants are connected to the national electricity grid, supplying about 65 megawatts. These include Nyagak I (3.5 megawatts), Kabalega (9 megawatts), Kanungu (6.6 megawatts), Bugoye (13 megawatts), Mubuku I (5 megawatts), Mubuku III (10 megawatts), and Mpanga (18 megawatts). Thermal power Two heavy fuel oil thermal power stations exist in the country. Namanve Power Station is a 50 megawatt plant formerly owned by Jacobsen Electricity Company (Uganda) Limited, a wholly owned subsidiary of Jacobsen Elektro, an independent Norwegian power production company.
