Electricity sector in Argentina

The electricity sector in Argentina constitutes the third largest power market in Latin America. It relies mostly on thermal generation (54% of installed capacity) and hydropower generation (41%), with new renewable energy technologies barely exploited. The country still has a large untapped hydroelectric potential. However, the prevailing natural gas-fired thermal generation is at risk due to the uncertainty about future gas supply.

Faced with rising electricity demand (over 6% annually) and declining reserve margins, the government of Argentina is in the process of commissioning large projects, both in the generation and transmission sectors. To keep up with rising demand, it is estimated that about 1,000 MW of new generation capacity are needed each year. An important number of these projects are being financed by the government through trust funds, while independent private initiative is still limited as it has not fully recovered yet from the effects of the Argentine economic crisis (1999-2002). The need to raise the currently low residential tariffs, which were frozen as a response to the crisis, is still a controversial political issue pending resolution.

The electricity sector was unbundled in generation, transmission and distribution by the reforms carried out in the early 1990s. Generation occurs in a competitive and mostly-liberalized market in which 75% of the generation capacity is owned by private utilities. In contrast, the transmission and distribution sectors are highly regulated and much less competitive than generation.

Electricity supply and demand


Thermal plants fueled by natural gas (CCGT) are the leading source of electricity generation in Argentina. Argentina generates electricity using thermal power plants based on fossil fuels (54%), hydroelectric plants (41%), and nuclear plants (4%, two operational, one incomplete), with less than 0.1 % renewable CAMMESA] . Installed nominal capacity in 2006 was 24,046 MW Cámara Argentina de la Construcción 2006] However, this scenario of gas dominance is likely to undergo changes due to gas exhaustion derived from the existing “bottlenecks” in exploration and production (E+P) and pipeline capacity. Gas output dropped for the first time ever in 2005 (-1.4%) and gas reserves dropped to ten years of consumption by the end of 2004 (down from an average of 30 years in the 1980s). [Oxford Analytica 2006] Today, gas reserves are 43% lower than in 2000 [ [http://www.econometrica.com.ar/productosservicios/archivos/especiales/iespecial_377.pdf Econométrica] ] . This situation is further aggravated by the uncertainty surrounding the gas deals with Bolivia and the plans to build new regional pipeline connections. Total generation in 2005 was 96.65 TW·h. The breakdown by source in 2003 had been: 59 % from conventional thermal sources, 35.4 % from hydroelectricity, 7 % from nuclear power and 1 % from geothermal sources. Secretaría de Energía 2006]

The generators are divided into eight regions: Cuyo (CUY), Comahue (COM), Northwest (NOA), Center (CEN), Buenos Aires/Gran Buenos Aires (GBA-BAS), Littoral (LIT), Northeast (NEA) and Patagonia (PAT).

Imports and exports

In 2005, Argentina imported 6.38 TW·h of electricity while it exported 3.49 TW·h Secretaría de Energía 2006] . Net energy imports thus were about 3% of consumption.

Argentina also imports electricity from Paraguay, produced by the jointly built Yaciretá Dam. On 18 September 2006 Paraguay agreed to settling its debt of $11,000 million owed to Argentina for the construction of Yaciretá by paying in electricity, at the rate of 8,000 GW per year for 40 years.


Electricity demand in Argentina has steadily grown since 1991, with just a temporary decline caused by the economic crisis of 2001-2002 [http://www.eia.doe.gov/emeu/cabs/Argentina/Electricity.html EIA] ] that has been followed by a quick recovery (6%-8% annual increase) in the last five years Cámara Argentina de la Construcción 2006] , partially due to economic recovery. In 2005, the country consumed 94.3 TW·h of electricity, which corresponds to 2,368 kW·h per capita. Residential consumption accounted for 29% of the total, while industrial, and commercial and public represented 43% and 26% respectively. Secretaría de Energía 2006]

Demand and supply projections

Argentina currently faces a tight supply/demand scenario as reserve margins have declined from above 30 % in 2001 to less than 10 %. This fact, together with the deterioration in distribution companies services (i.e. cables, transformers, etc), has the potential to endanger supply. To sustain a 6-8% annual increase in demand, it is estimated that the system should incorporate about 1,000 MW of generation capacity each year. [ [http://www.clarin.com/diario/2006/10/11/elpais/p-00301.htm El País] ]

Transmission and distribution

In Argentina, there are two main interconnected systems, SADI ("Sistema Argentino de Interconexión", Argentine Interconnected System) in the North and center-South of the country, and SIP ("Sistema Argentino de Interconexión", Patagonian Interconnected System) in the South. Both systems are integrated since March 2006. "Coordinación de Energías Renovables 2006"] The electricity market in the SADI area is managed by the MEM ("Mercado Eléctrico Mayorista").

Total electricity coverage in Argentina was as high as 95% in 2003 [http://info.worldbank.org/etools/lacelectricity/home.htm Benchmarking data of the electricity distribution sector in Latin America and Caribbean Region 1995-2005] ] . However, about 30% of the rural population lacks access to electricity. [ [http://energia.mecon.gov.ar/permer/PERMER.html PERMER] ] The Renewable Energy in the Rural Market Project (PERMER) is one of the programs that are being implemented to enlarge electricity coverage in rural areas.(See World Bank projects below).

Interruption frequency and duration

Interruption frequency and duration are considerably below the averages for the LAC region. In 2002, the average number of interruptions per subscriber was 5.15, while duration of interruptions per subscriber was 5.25 hours. The weighted averages for LAC were 13 interruptions and 14 hours respectively.

Responsibilities in the Electricity Sector

Policy and regulation

The Energy Secretariat (SENER) is responsible for policy setting, while the National Electricity Regulator (ENRE) is the independent organism within the Energy Secretariat that holds the responsibility of applying the regulatory framework established by the Law 26,046 of 1991. ENRE is in charge of regulation and overall supervision of the sector under federal control. Provincial regulators regulate the rest of the utilities. ENRE and the provincial regulators set tariffs and supervise compliance of regulated transmission and distribution entities with safety, quality, technical and environmental standards. CAMMESA ("Compañía Administradora del Mercado Mayorista Eléctrico") is the administrator of the wholesale electricity market. Its main functions include the operation and dispatch of generation and price calculation in the spot market, the real-time operation of the electricity system and the administration of the commercial transactions in the electricity market. Cámara Argentina de la Construcción 2006]

The Electric Power Federal Council (CFEE), created in 1960, plays a very important role in the sector as well. It is the administrator of the Funds that specifically target electricity operations (i.e. National Fund for Electric Power, see Recent developments below) and is also an adviser to the National and the Provincial Governments in issues relating to the power industry, public and private energy services, priorities in the execution of new projects and studies, concessions and authorizations, and electricity tariffs and prices. It is also an adviser for legislative modifications in the power industry. [ [http://www.cfee.gov.ar/marcos.htm Electric Power Federal Council (CFEE)] ]

The Argentine power sector is one of the most competitive and deregulated in South America. However, the fact that the Energy Secretariat has veto power over CAMMESA has the potential to alter the functioning of the competitive market. The functions of generation, transmission, and distribution are open to the private sector, but there are restrictions on cross-ownership between these three functions. Argentine law guarantees access to the grid in order to create a competitive environment and to allow generators to serve customers anywhere in the country. [http://www.eia.doe.gov/emeu/cabs/Argentina/Electricity.html EIA] ]


Private and state-owned companies carry out generation in a completive, mostly-liberalized electricity market, with 75 % of total installed capacity in private hands. The share in public hands corresponds to nuclear generation and to the two bi-national hydropower plants: Yacyretá (Argentina-Paraguay) and Salto Grande (Argentina-Uruguay). The generation sector is highly fragmented with more than ten large companies, all of them below 15 % of the system’s total capacity. Secretaría de Energía 2006] Power generators sell their electricity in the wholesale market operated by the CAMMESA [http://www.eia.doe.gov/emeu/cabs/Argentina/Electricity.html EIA] ] .

Transmission and distribution

The transmission and distribution sectors are highly regulated and less competitive than generation. In transmission, the Compañía Nacional de Transporte Energético en Alta Tension (Transener) operates the national electricity transmission grid under a long-term agreement with the Argentine government. In the distribution sector, three private companies, Edenor ("Empresa Distribuidora y Comercializadora Norte"), Edesur ("Electricidad Distribuidora Sur") and Edelap ("Empresa de Electricidad de la Plata"), dominate a market with 75% control by private firms. [http://www.eia.doe.gov/emeu/cabs/Argentina/Electricity.html EIA] ]

Other important distribution companies at the provincial level are:

* Public provincial: EPEC ("Empresa Provincial de Energía de Córdoba"), EPESFI ("Empresa Provincial de Energía de Santa Fé)
* Private provincial: ESJ (" Energía San Juan"), EDET ("Empresa de Distribución Eléctrica de Tucumán"): EDEN ("Empresa Distribuidora de Energía Norte"), EDEA ("Empresa Distribuidora de Energía Atlántica"), EDES ("Empresa Distribuidora de Energía Sur")

Renewable energy resources

The National Promotion Direction (DNPROM) within the Energy Secretariat (SENER) is responsible for the design of programs and actions conducive to the development of renewable energies (through the [http://energia3.mecon.gov.ar/contenidos/verpagina.php?idpagina=949 Renewable Energy Coordination] ) and energy efficiency (through the [http://energia3.mecon.gov.ar/contenidos/verpagina.php?idpagina=865 Energy Efficiency Coordination] ) initiatives. [http://www.eia.doe.gov/emeu/cabs/Argentina/Electricity.html EIA] ] Complementarily, the Secretariat for the Environment and Natural Resources (SEMARNAT) is responsible for environmental policy and the preservation of renewable and non-renewable resources. "Coordinación de Energías Renovables 2006"]

The most important legal instruments for the promotion of renewable energy are Law 25,019 from 1998 and Law 26,190, from 2007. The 1998 Law, known as the “National Wind and Solar Energy Rules”, declared wind and solar generation of national interest and introduced a mechanism that established an additional payment per generated kW·h which, in 1998, meant a 40% premium over market price. It also granted certain tax exemptions for a period of 15 years from the law’s promulgation. Cámara Argentina de la Construcción 2006] The 2007 Law complemented the previous one declaring of national interest the generation of electricity from any renewable source intended to deliver a public service. This Law also set an 8 % target for renewable energy consumption in the period of 10 years and mandated the creation of a Trust Fund whose resources will be allocated to pay a premium for electricity produced from renewable sources.


Argentina’s hydroelectric potential is being exploited only partially. While the identified potential is of 170,000 GW·h/year, in 2006 hydroelectric production amounted just to 42,360 GW·h. "Coordinación de Energías Renovables 2006"] There are also untapped mini-hydropower resources, whose potential is estimated at 1.81 % of overall electricity production (in contrast with its current 0.88 %) " [http://energia3.mecon.gov.ar/contenidos/verpagina.php?idpagina=949 Coordinación de Energías Renovables "] ] .

(For a comprehensive list of plants see )


The Argentine Patagonia region, has a very large wind potential. The Chubut Wind Power Regional Center (CREE) estimated the theoretical potential for the region at 500 GW of electricity generation. However, this large potential is still largely unexploited. One of the reasons for this underdevelopment is that existing tariffs and incentives do not make wind power development attractive enough yet. However, the main deterrent to wind power development in the region has been the lack of tranmission lines that connect the Patagonia region with the National Interconnected System. [ [http://www.inti.gov.ar/sabercomo/sc32/inti9.php "Instituto Nacional de Tecnología Industrial"] ] The completion of the Choele-Choel-Puerto Madryn high voltage line, the first section of "Línea Patagónica", under the framework of the "Plan Federal de Transporte de Energía Eléctrica" eliminated this bottleneck in March 2006 [http://www.obraspublicas.com.ar/noticia_ampliada.php?vid=31409 Public works news] ] .

Nevertheless, wind power has increased significantly in Argentina during the last decade. Total operating wind power capacity in 2005 was 26.6 MW, shared by 13 plants. This is still only about 0.05% of the theoretical potential of wind energy in Argentina. The distribution of number plants and total capacity is: [http://energia3.mecon.gov.ar/contenidos/verpagina.php?idpagina=949 "Coordinación de Energías Renovables "] ]

* Santa Cruz Province: 1 plant, 2,400 kW
* La Pampa Province : 1 plant, 1,800 kW
* Neuquen Province : 1 plant, 400 kW

Of the 13 plants, only three have been commissioned after the year 2000, with the remaining 10 built during the 1990s. " [http://energia3.mecon.gov.ar/contenidos/verpagina.php?idpagina=949 Coordinación de Energías Renovables "] ]

Solar power is only present in remote areas. Just 81 MW·h were generated in 2005, less than 0.1% of total electricity production. SENER 2007]

History of the electricity sector

The reforms of 1991/92

Prior to 1991, the electricity sector in Argentina was vertically integrated. The sector experienced a serious crisis in the summers 1988/1989, which was mainly due to the lack of maintenance of the country’s thermal power plants (50 % of them were unavailable) [http://www.monografias.com/trabajos15/energia-electrica-argentina/energia-electrica-argentina.shtml "La Energía Eléctrica en la República Argentina"] ] . Shortly after the crisis, the government of Carlos Menem introduced a new legal framework for the electricity sector through Law 24,065, which included the following elements: vertical and horizontal unbundling of generation, transmission and distribution; opening up of all segments to the private sector; and separation of the regulatory function from policy setting. As a result of the new law, there was susbtantial private investment which, together with the public power plants that started production in the 1990s, transformed a situation of power shortage and low quality into one of abundance and reliability at lower prices. [http://www.enre.gov.ar/ ENRE] ]

ENRE (Electricity National Regulatory Entity) was created in 1992. The Wholesale Electricity Market (MEM), which covers up the 93% of total demand corresponding to the Argentine Interconnected System (SADI) was also created in 1992. The remaining 7% share of the demand corresponds to Patagonia , which had its own interconnected market, the Patagonian Wholesale Electricity Market MEMSP), now interconnected with the MEM. CAMMESA (Wholesale Electricity Market Administration Company) was also created that year and assigned the responsibilities of coordinating dispatch operations, setting wholesale prices and administrating economic transactions performed through the Argentine Interconnected System. [http://www.monografias.com/trabajos15/energia-electrica-argentina/energia-electrica-argentina.shtml "La Energía Eléctrica en la República Argentina"] ]

The reforms implemented in the 1990s led to high investment, which allowed for a 75 % increase in generation capacity, resulting in the decrease of prices in the wholesale market from US$40/MW·h in 1992 to US$23/MW·h in 2001. However, the reforms failed to deliver the necessary increase in transmission capacity. Only one relevant project, the addition of the 1,300 km high voltage line between Comahue and Buenos Aires, was built in the 1990s. Distribution networks were also renovated and expanded, which resulted in efficiency and quality improvements. [http://www.energy.org.ar/GON/s&p.pdf Standard and Poor’s] ]

Tariff freeze

As a response to the 2001 economic crisis, electricity tariffs were converted to the Argentine peso and frozen in January 2002 through the Public Emergency and Exchange Regime Law. Together with high inflation (see Economy of Argentina) and the devaluation of the peso, many companies in the sector had to deal with high levels of debt in foreign currency under a scenario in which their revenues remained stable while their costs increased. This situation has led to severe underinvestment and unavailability to keep up with an increasing demand, factors that contributed to the 2003-2004 energy crisis. [http://www.energy.org.ar/GON/s&p.pdf Standard and Poor’s] ] Since 2003, the government has been in the process of introducing modifications that allow for tariff increases. Industrial and commercial consumers’ tariffs have already been raised (near 100% in nominal terms and 50% in real terms), but residential tariffs still remain low.

Creation of Enarsa

In 2004, President Néstor Kirchner created "Energía Argentina Sociedad Anónima" (Enarsa), a company managed by the national state of Argentina for the exploitation and commercialization of petroleum and natural gas, but also the generation, transmission and trade of electricity. Through the creation of Enarsa, the state will regain a relevant place in the energy market that was largely privatized during the 1990s.

Energy Plus and Gas Plus programs

In September 2006, SENER launched the Energy Plus ("Energía Plus") program with the objective of increasing generation capacity and meet raising electricity demand. The program applies for consumption levels above those for 2005. CAMMESA requires all large users (above 300 kW) to contract the difference between their current demand and their demand in the year 2005 in the Energy Plus market. In this new de-regulated market, only energy produced from new generation plants will be traded. The aim of the program is twofold. On the one hand, it seeks to guarantee supply to residential consumers, public entities, and small and medium enterprises. On he other hand, it aims at encouraging self-generation by the industrial sector and electricity cogeneration. [http://www.enre.gov.ar/ ENRE] ]

In March 2008, the Government approved Resolution 24/2008, which created a new natural gas market called “Gas Plus” to encourage private investment in natural gas exploration and production. The Gas Plus regime applies to new discoveries and to “tight gas” fields. The price of the new gas, whose commercialization will be restricted to the domestic market, will not be subject to the conditions established in the “Agreement with Natural Gas Producers 2007-2011” but will be based on costs and a reasonable profit. Experts believe that, if the Gas Plus regime is successful, it could stimulate new investments in electricity generation plants under the Energy Plus regime as it could ensure fuel supply to the new plants. [Resolution 24/2008 Secretariat of Energy]

The National Program for the Rational and Efficient Use of Energy (PRONUREE)

In December 2007, the Government launched the National Program for the Rational and Efficient Use of Energy (PRONUREE, Decree 140/2007). This Decree declared the rational and efficient use of energy to be in the national interest and is also part of the energy sector strategy to counter supply/demand imbalance. The PRONUREE, under the responsibility of the Secretariat of Energy, aims to be a vehicle for improving energy efficiency in the energy-consuming sectors and acknowledges that energy efficiency needs to be promoted with a long-term commitment and vision. It also acknowledges the connection between energy efficiency and sustainable development, including the reduction of greenhouse gas emissions. The Program also recognizes the need for individual behavioral changes to be promoted with an educational strategy, with the public sector setting the example by assuming a leadership role in the implementation of energy conservation measures in its facilities. [http://www.enre.gov.ar/web/web.nsf/Files/PRONUREE_Decreto140.pdf/$FILE/PRONUREE_Decreto140.pdf Decree 140/2007] ]

The PRONUREE includes short and long term measures aimed at improving the energy efficiency in the industrial, commercial, transport, residential and service sectors and public buildings. It also supports educational programs on energy efficiency, enhanced regulations to expand cogeneration activities; labeling of equipment and appliances that use energy; improvements to the energy efficiency regulations; and broader utilization of the Clean Development Mechanism (CDM) to support the development of energy efficiency projects. [http://www.enre.gov.ar/web/web.nsf/Files/PRONUREE_Decreto140.pdf/$FILE/PRONUREE_Decreto140.pdf Decree 140/2007] ] The objective of the program is to reduce electricity consumption by 6% [http://buscador.lanacion.com.ar/Nota.asp?nota_id=995820&high=PRONUREE La Nación 5 January 2008] ]

One of the first activities defined under PRONUREE is the national program to phase out incandescent bulbs by 2011 in Argentina. The program, financed by the government, aims to replace incandescent bulbs with energy efficient compact fluorescent lamps (CFLs) in all the households connected to the electricity grid and selected public buildings. The program, which has initially undergone a pilot phase and expects to replace 5 million incandescent lamps in the next six months. [http://buscador.lanacion.com.ar/Nota.asp?nota_id=992672&high=PRONUREE La Nación 4 March 2008] ] , foresees the distribution of 25 million lamps overall. [http://buscador.lanacion.com.ar/Nota.asp?nota_id=995820&high=PRONUREE La Nación 15 March 2008] ] . Staff from the distribution companies will visit each household to replace the incandescent lamps and to inform residential users on the advantages of replacing the bulbs and of the efficient use of energy in general..

Recent tariff increases, 2008

In Argentina, retail tariffs for the distribution utilities in the Metropolitan Area of Buenos Aires and La Plata city (i.e. Edenor, Edesur and Edelap) are regulated by the national regulatory agency (ENRE) while provincial utilities are regulated by local regulators. While the utilities under ENRE’s jurisdiction had not been allowed to raise residential tariffs since they were frozen in 2002 as a result of the Emergency and Exchange Regime Law, some provincial regulators had recently approved additional charges to residential tariffs. In particular, the Public Service Regulatory Agency in the Province of Córdoba (ERSeP) agreed in February 2008 [ [http://www.boletinoficialcba.gov.ar/archivos08/110308_resoluciones.pdf General Resolution No. 04/2008] ] to a 17.4% additional charge to residential customers. Likewise, Santa Fé approved increases between 10% and 20% [ [http://www.elsantafesino.com/politica/2008/02/13/6819 El Santafesino] ] ; Mendoza between 0 and 5% below 300 kWh and between 10% and 27% above 300 kWh [ [http://www.diariopanorama.com/diario/edicionant/2008/02/08/a-15333.html Diario Panorama] ] , [ [http://www.prensa.mendoza.gov.ar/modules.php?name=News&file=article&sid=2245 Prensa Mendoza] ] ; Jujuy between 22% and 29% and Tucumán between 10% and 24% Urgente 24] . Other provinces (i.e. San Juan, Chaco, Formosa, Corrientes, La Pampa, Neuqen, Río Negro, Entre Ríos) are expected to raise tariffs in the near future Urgente 24] .

Recently, in August 2008, after a 7-year tariff freeze, residential electricity tariffs in the Buenos Aires metropolitan area (served by the Edenor, Edesur and Edelap utilities) have been increased by 10-30% for households that consume more that 650kwh every two months. For consumption between 651Kwh and 800 Kwh, the increase will be 10%; on the other end, for users over 1,201 Kwh, the increase amounts to 30%. The increase impacts around 24% of all Edenor, Edesur and Edelap customers (1,600,000 households). For commercial and industrial users the increase will be 10%. [Resolution ENRE 356/08]

At the end of August 2008, ENRE also approved increases in transmission tariffs in the 17%-47% range [Resolutions ENRE 327, 328/08] . The increase granted by ENRE was below the increase determined by the Energy Secretariat for some distribution companies (e.g. Transener, Transba, Distrocuyo and Transnoa. Some of them (i.e. Transener, Transba), will most likely challenge ENRE's decision [ [http://www.clarin.com/diario/2008/08/16/elpais/p-01738946.htm Diario Clarín,16th Aug 2008] ] . An overall tariff revision is still pending and has been put off until February 2009 [Resolutions Energy Secretariat 864, 865, 866/08] .

Tariffs, cost recovery and subsidies


Electricity tariffs in Argentina are well below the LAC average. In 2004, the average residential tariff was US$0.0380 per kW·h, very similar to the average industrial tariff, which was US$0.0386 per kW·h in 2003. Weighted averages for LAC were US$0.115 per kW·h for residential consumers and US$0.107 per kW·h for industrial customers. [http://info.worldbank.org/etools/lacelectricity/home.htm Benchmarking data of the electricity distribution sector in Latin America and Caribbean Region 1995-2005] ] (See History of the electricity sector for more information on the evolution of tariffs).


See Fund for the Electric Development of the Interior (FEDEI) below.

Investment and financing

In 1991, the Government of Argentina created the National Fund for Electric Power (FNEE, "Fondo Nacional de la Energía Eléctrica"), to be funded by a share of the petrol tax and a surcharge on sales from the wholesale market. This Fund, which is administered by CFEE (Electric Power Federal Council), provides funding to the following other funds at the shares indicated [ [http://www.cfee.gov.ar/Aplicacion%20de%20los%20fondos%202003.htm Electric Power Federal Council (CFEE)] ] :

* 47.4%: Subsidiary Fund for Regional Tariff Compensation to Final Users (FCT), for homogenization of tariffs across the country (this created a de facto subsidy for those consumers in the areas with higher electricity costs)
* 31.6%: Fund for the Electric Development of the Interior (FEDEI), for generation, transmission and rural and urban distribution works. Most funds have been directed to rural electrification
* 19.75%: Fiduciary Fund for Federal Electricity Transmission(FFTEF) (created in 2000), for co-financing or projects in electricity transmission.
* 1.26%: Wind Energy Fund (created in 2002), for the development of wind energy,

In addition, CAMMESA, the administrator of the wholesale electricity market, had projected that, by 2007, the country’s energy demand would require an additional capacity of 1,600 MW. Faced with the need for specific investments but also with a lack of private investment, the Energy Secretariat (SENER) enacted Resolutions 712 and 826 in 2004, which created FONINVEMEM, the Fund for the Investment Needed to Increase the Supply of Electricity in the Wholesale Market. The Fund, which sought to encourage participation from creditors of the wholesale market, invited those creditors, mainly generation companies, to participate with their credit to the creation of the Fund itself.

Ongoing projects

There are several projects that are part of the Government’s response to the predicted electricity shortages. If all those plans are completed as expected, the capacity requirements for the next few years will be met.

Thermal power

Two new CCGT plants, the José de San Martín Thermoelectric and Manuel Belgrano Thermoelectric, of 830 MW each, are currently under construction and expected to start full operations at the beginning of 2009. Endesa, Total S.A., AES Corporation, Petrobras, EDF and Duke Energy are the main shareholders in the plants. Both plants, which have been financed through the FONINVEMEM (total investment amounts up to US$1,097 million), are expected to start full operations at the beginning of 2009. [ [http://www.siemens.com.ar/sites/internet/legacy/sie-prensa/ultimas/new_plantas_energeticas.htm SIEMENS] ] .

In addition, the Planning Ministry announced in July 2007 the commissioning of five new thermal plants with a total capacity of 1.6 GW and an overall investment of US$3,250 million. These dual-generation turbine (gas or fuel oil) plants, which are expected to start operations in 2008, will be located in Ensenada (540 MW), Necochea (270 MW), Campana (540 MW), Santa Fe (125 MW) and Córdoba (125 MW). [ [http://aristotelizar.com/web/2007/07/19/anuncian-la-construccion-de-cinco-centrales-electricas-que-produciran-1600-megavatios/ Aristotelizar online news] ] Finally, Enarsa has recently launched bidding for eleven small and transportable generation units (15-30 MW each) and for other three larger generation units (50-100 MW) to be installed on barges. These new units, whose base price is still unknown, will add between 400 and 500 MW of new generation capacity. [ [http://www.electroindustria.com/nuevo/noticia.asp?inf_id=5997 Electroindustria] ]

Nuclear power

In 2006, the Argentine government launched a plan to boost nuclear energy. The Atucha II nuclear power plant, whose construction started in 1981, will be completed and will add 750 MW of generation capacity by 2010. In addition, the Embalse nuclear power plant, with 648 MW of generation capacity, will be refurbished to extend its operational life beyond 2011. [ [http://www.cnea.gov.ar/xxi/noticias/2007/ago07/atuchaII.asp National Atomic Commission] ]


On the hydropower side, the Yacyretá dam is being elevated by 7 m to the height of 83 m contemplated in its original design, which will increase its capacity from 1,700 to 3,100 MW. This will lead to a 60% increase in its electricity output (from 11,450 GW·h to 18,500 GW·h). Cámara Argentina de la Construcción 2006] The works are to be finalized in 2008 [ [http://www.eby.org.ar/ Entidad Nacional Yacyretá] ] , although the serious controversy regarding the resettlement of people from the new areas to be inundated in the Paraguayan side is likely to delay completion of the project. Finally, in 2006, bidding for the expansion of Yacyretá with the construction of a new 3-turbine plant in the Añá Cuá arm of the Paraná River was announced by the Government. This expansion, to be finalized in 2010, would add 300 MW of new generation capacity. [ [http://www.lanacion.com.ar/archivo/Nota.asp?nota_id=774875 Na Nación] ]


In regard to transmission, the Plan Federal de Transporte de Energía Eléctrica en 500 kV is under implementation under the umbrella of the FFTEF (Fondo Fiduciariopara el Transporte Eléctrico Federal) Cámara Argentina de la Construcción 2006] . The main lines in the plan (Línea Patagónica, Línea Minera, Yacyretá, Puerto Madryn – Pico Truncado, NEA-NOA, Comahue – Cuyo, Pico Truncado – Río Turbio –Río Gallegos) are already built or currently under construction. The lines built between 2007 and 2009 will add 4,813 new kilometers of high voltage transmission capacity.

In addition, the Plan Federal de Transporte de Energía Eléctrica II, defined in 2003 and updated in 2006, has the objective of addressing the constraints faced by the regional transmission networks in the period up to 2010. This complementary plan has prioritized the necessary works according to their ability to address short-term demand issues. 109 of the 240 works identified in 2003 were considered of high priority and have already been completed or are under execution. Initially, investment for high priority works was estimated at US$376 million while estimated investment for the rest of the works totaled US$882.2 million. However, this budget is under revision due to the increasing costs of materials such as steel and aluminum and of labor.Cámara Argentina de la Construcción 2006]

ummary of private participation in the electricity sector

Prior to 1991, the electricity sector in Argentina was vertically integrated. The new legal framework for the electricity sector included: vertical and horizontal unbundling of generation, transmission and distribution; opening up of all segments to the private sector; and separation of the regulatory function from policy setting.

Currently, private and state-owned companies carry out generation in a completive, mostly-liberalized electricity market, with 75 % of total installed capacity in private hands. The share in public hands corresponds to nuclear generation and to the two bi-national hydropower plants: Yacyretá (Argentina-Paraguay) and Salto Grande (Argentina-Uruguay). On the other hand, the transmission and distribution sectors are highly regulated and less competitive than generation. In transmission, the Compañía Nacional de Transporte Energético en Alta Tension (Transener) operates the national electricity transmission grid, while in the distribution sector, three private companies, Edenor (Empresa Distribuidora y Comercializadora Norte), Edesur (Electricidad Distribuidora Sur) and Edelap (Empresa de Electricidad de la Plata), dominate a market with 75% control by private firms.

Electricity and the Environment

Responsibility for the environment

The [http://www.ambiente.gov.ar/ Secretariat of Environment and Sustainable Development] holds the responsibility for the environment in Argentina.

Greenhouse gas emissions

[http://www.olade.org OLADE] (Organización Latinoamericana de Energía) estimated that CO2 emissions from electricity production in 2003 were 20.5 million tons of CO2, which represents 17 % of total emissions for the energy sector [ [http://www.olade.org/informe.html OLADE] ] .

CDM projects in electricity

Currently (August 2007), there are only three energy-related registered CDM projects in Argentina, with expected total emissions reductions of 673,650 tons of CO2e per year [ [http://cdm.unfccc.int/Projects/projsearch.html UNFCCC] ] . Out of the three projects, there is just one large scale one, the 10.56 MW [http://cdm.unfccc.int/Projects/DB/DNV-CUK1132045363.5/view.html Antonio Morán wind power plant] in the Patagonia region.

This project has the objective of guaranteeing access to electricity to 1.8 million people (314,000 households) and to 6,000 public services (schools, hospitals, etc.) located far from electricity distribution centers. Electrification of this dispersed market will be mostly carried out through the installation of solar PV systems, but also through other technologies such as micro-hydraulic turbines, wind and, eventually, diesel generators. [ [http://energia.mecon.gov.ar/permer/PERMER.html PERMER] ] The project, which started in 1999 and is expected to end in December 2008, has received a US$10 million grant from GEF and a US$30 million loan from the World Bank.
