Duke Energy International (DEI) owns, operates or has substantial interests in approximately 4,900 gross megawatts of electric generation primarily in Latin America. DEI also owns a 25 percent interest in National Methanol Company, a Saudi Arabian regional producer of MTBE, a gasoline additive. DEI's customers include retail distributors, electric utilities, independent power producers, marketers and industrial/commercial companies. Nearly two-thirds of DEI's generating capacity is hydroelectric.
In 2012, DEI expanded its presence to Chile with the acquisition of the Yungay plant (formerly known as the Campanario plant), a 240-megawatt diesel generating facility. DEI later acquired CGE Group's Iberoamericana de Energía Ibener S.A. (Ibener) subsidiary, including two run-of-river hydroelectric power plants Peuchén and Mampil with a combined installed capacity of 140 megawatts.

Duke Energy Argentina has been generating and distributing electrical power since the year 2000. It also distributes natural gas at the wholesale sales level. Between the plants and the offices, the company has 110 employees.
The assets that generate electrical power and natural gas in Argentina are: Planicie Banderita Hydroelectric Power Plant (Cerros Colorados) and Alto Valle Thermoelectric Power Plant. Both plants are located in the Province of Neuquén, in southern Argentina, and the total electric generating capacity is 576 megawatts. The business offices are located in Buenos Aires, the capital of Argentina.
Cerros Colorados hydroelectric complex is located in the lower valley of the Neuquén River, 60 km (38 miles) northwest of the city of Neuquén. The Planicie Banderita power plant is located at the bottom of the dam, and its installed capacity is 479 MW with an annual generation average of 1,521 GWh. Besides generating electrical power, the main objectives at Cerros Colorados hydroelectric complex are to: control flooding, regulate flow, and ensure fresh water for drinking and irrigation.
The Alto Valle thermoelectric power plant, located in the city of Neuquén, operates by natural gas that originates from the Neuquén basin. Its installed capacity is 97 MW and has two independent units of combined cycle, each one equipped with a 25 MW gas turbine and a 15 MW steam turbine. This plant also has a 17 MW gas turbine (open cycle). Alto Valle distributes the generated energy to the national grid which is connected to the local transmission network. The annual energy generated varies, depending largely on the supply and demand conditions in the electric power market.

Paranapanema and Sapucai-Mirim Rivers: two springs of life and biodiversity that feed Duke Energy's hydroelectric plants in Brazil which, for more than a decade, contribute to the growth of the communities where they operate as well as the economic development of the country.
Duke Energy began operating in Brazil in 1999, following the acquisition of Paranapanema Electricity Generation Company (CESP), and is now responsible for generating 2.3% of the energy in the country.
Duke Energy Brazil has two hydro power generating companies: Geração Paranapanema, consisting of eight plants distributed along the Paranapanema River; and DEB (Small Hydro Powers), which manages two power plants located on the Sapucai-Mirim River, between the cities of Sao Joaquim da Barra and Guara (Sao Paulo State). Together, the two operations generate 2,274 MW.
Currently, 100% of the electricity generated by Duke Energy Brazil comes from hydroelectric sources. In recent years, the company produced an average of 880,000 MWh/month, enough energy to sustain a city of more than 3 million people for a complete month.
The operation and maintenance procedures defined by the company, along with a policy of investment in modernization of equipment and systems, classifies Duke Energy Brazil among the companies that have one of the best operating performance indicators in the electric power generation sector.

DEI has been operating in Chile since June 2012, when the company acquired the Yungay thermal plant (formerly known as Campanario plant), and strengthened its presence and commitment in the country when it acquired the Duqueco hydroelectric complex in the VIII region in Chile in December 2012.
The generation facilities acquired by the company are the Yungay thermal plant with an installed capacity of 240 MW, and the Duqueco hydroelectric complex with an installed capacity of 140 MW, which combine for a total installed capacity of 380 MW. Therefore, Chile is now the fourth largest country in terms of generating capacity for Duke Energy's international operations.
Peuchén power plant
Peuchén is a run-of-river hydroelectric plant in the Santa Barbara district, which is located 72 km (45 miles) east of Los Angeles, in the Biobío region.
This power plant uses the water from the Duqueco River to generate electricity through an impoundment reservoir in La Junta, in the confluence of Duqueco, Aillín and Quilaquín Rivers.
Mampil power plant
Mampil is a run-of-river hydroelectric plant located on the Duqueco River. Down the river from the Peuchén hydroelectric station, Mampil hydroelectric station lies in the Santa Barbara community in the Biobío region. Mampil uses the water flows from Peuchén and both hydroelectric plants operate together.
Yungay thermal plant
Yungay thermal plant is located in the Cabrero community in the southern region of Chile. It operates three generating units - two turbines per unit - of 60 megawatts each and one combined cycle of 60 megawatts. All are diesel-operated units.

In Ecuador, Duke Energy is the majority shareholder of Electroquil S.A. a power generating company operating since 1991. The company was idealized by a group of businessmen from Guayaquil who were concerned about the energy crisis that the country was facing in the early 90's.
To achieve this project, the biggest industrial and commercial consumers at that time from Guayaquil decided that for each KWh produced by the company, they would pay an additional one American penny, which would capitalize Electroquil. In the first year of operation, and as a result of their decision, they were able to install two gas turbines of 25 and 50 MW.
In February 1998, Duke Energy International purchased 50.5% of the company, taking control and becoming the majority shareholder. At present, Duke Energy holds 85% of the capital and has enhanced the capacity to 192 MW through 4 Aeroderivative turbines (General Electric LM 6000).
In 2008 and 2010, the company was recognized as being a role model by CONELEC, Consejo Nacional de Electrididad, because it met and surpassed the environmental standards. In 2011, it received from the city of Guayaquil the "ECO EFICIENCIA" award. This award is a means of recognizing the companys constant efforts in preserving the environment and offering a better way of life to the communities.

DEI has a 25% equity investment in a regional producer of methanol and MTBE called National Methanol Co. (NMC), located in Saudi Arabia.
NMC was formed through a joint venture agreement signed in 1981 by Saudi Basic Industries Corporation (SABIC) holding 50% and CTE Petrochemicals Company (CTE) holding 50%. CTE is a 50/50 partnership between Celanese and Duke Energy.
The Saudi unit produces methanol and MTBE - a gasoline additive that reduces the emission of carbon monoxide from vehicles.
The NMC methanol operations began in 1984, and in 1994 the company began production of MTBE. Today, the company produces 1 million metric tons (MT) per year of MTBE and methanol. The main resources to produce these products are natural gas and butane.
In 2011, NMC began constructing a 50,000 ton facility in Saudi Arabia to produce Polyacetal (POM) - an engineering thermoplastic used to make precision parts. Completion is expected in early 2016.
DEI's share of NMCs earnings has historically contributed ~20-30% of DEIs Adjusted Segment EBIT.
