Marchegiani, Universidad Nacional del Comahue, Argentina Key facts Population 42,192,494 1 Area 2,780,400 km 2 Climate Mostly temperate; arid in southeast; sub-antarctic in southwest 1 Topography Rich plains of the Pampas in northern half, flat to rolling plateau of Patagonia in south, rugged Andes along western border 1 (highest point: Aconcagua, 6,960 m) Rain pattern Variable, depending on location and elevation Electricity sector overview The state's role in Argentina's energy sector has experienced profound changes since 1992, when the restructuring of the sector began. The generation, transmission and distribution of electricity were opened to the private sector, but restricted to the ownership of no more than one property in the sector. The approved legal framework guaranteed access to the grid, creating a competitive environment and allowing the installation of generators to serve customers anywhere in the country. Argentina has a high rate of electrification (95 per cent), but much of its rural population lacks electricity. Electricity is generated mainly through combustion (thermal plants), 30 per cent by large hydropower plants, 6 per cent by nuclear and less than 2 per cent from renewable energy sources, according to the Energy Department (figure 1). Electricity imported from Brazil, Paraguay or Uruguay is not uncommon in the winter months. According to the Argentine Association for Renewable Energy and Environment, the electricity from renewable energy is generated from 553 MW of installed capacity, of which 427 MW are small hydropower plants, 65 MW wind farms, 58 MW biomass (wood) plants and only 1.2 MW are solar panels.

4 The upper limit of 15 MW is only a convention proposed by Law /06 according to the rules and context of the United Nations Framework Convention on Climate Change (UNFCCC). If so, and assuming a conservative 115,000 GWh/year of electricity consumption by 2013 (and counting the existing 180 MW), small hydropower could supply 22.7 per cent of the minimum contribution proposal, or about 1.81 per cent of the total. The convention adopted by the National Directorate of Promotion (Dirección Nacional de Promoción) for small hydropower classifies small hydropower plants by recognizing nominal installed capacity. There are three intervals: Micro (5-50 kw), Mini ( kw), and Small (500 kw-15 MW). The total small hydropower potential per region of the Argentinean Electricity Interconnection System (Sistema Argentino de Interconexión Eléctrica) is given the table below. Small hydropower potential in Argentina (Megawatts) Potential category 5-50 kw kw 500 kw kw Total of region Central Comahue Cuyo Northeast Argentina Northwest Argentina Patagonia Total In terms of renewable energy sources, the Government strategy first considers the development of small hydropower plants (up to 15 MW), because these projects represent an opportunity for Argentina s sustainable development in multiple geographic regions. The Energy Department has a national inventory of 116 small hydropower projects, with capacities lower than 15 MW and which represent an additional power supply of nearly 430 MW (figure 3). 5 While the main small hydropower potential has been estimated to be over 400 MW, a new installed capacity of 100 MW may be incorporated within 10 years time in different regions of the country. Small hydropower projects with a total capacity of 30 MW are currently under development. Argentina has turbine manufacturers who are part of the clean energy value chain of small hydropower within the country. 3 The results of the mentioned study favor, among others, the small hydropower in the southern region and, in general, isolated projects, thus, improving economic performance. However, the level of development of the studies is low. Of the 116 projects reviewed, only four have reached implementation stage and only 20 have reached the feasibility stage. The need to carry out a small hydropower development plan has been proposed, which will make further hydrological, geological, geotechnical and environmental impact studies necessary (done for only 12 small hydropower sites). It is also suggested to evaluate the additional environmental benefits, social cost of externalities, as well as the capability to supply potable drinking water.

Renewable energy policy The importance of renewable resources (i.e. photovoltaic, wind, biomass and small hydropower plants) as alternative sources for generating electricity in rural areas has increased through various programmes that are being conducted by the Ministry of Public Works and Services at the National Bureau of Promotion, in order to achieve basic power provision and lighting and communications, although the main authority on energy is the Ministry of Planning. 3 Argentina has a national law on the promotion of renewable energy sources for the production of electricity (Law /06). It grants renewables the status of national interest and via a tax based incentive a non-binding renewable target of 8 per cent is set to be achieved by 2016, in addition to a 7 per cent biodiesel and a 5 per cent ethanol blending mandate. 3 Studies and maps have been made to determine the renewable energy potential in each province and in 2009, the law was regulated by presidential decree. That same year, the national Government, together with Energía Argentina Sociedad Anónima, the public power company, launched the GENREN programme, which offers to buy 1,000 MW of renewable energy 2

5 through fixed contracts for 15 years. The Undersecretary of Electricity under the Ministry of Energy's Office has established a programme to supply the dispersed rural population with power (Programa de Abastecimiento Eléctrico a la Población Rural dispersa de Argentina). It aims to collaborate with the provinces through provincial energy programmes to electrify rural areas, primarily using photovoltaic, wind, micro hydro turbines and diesel generators. The national context is important to highlight the development and implementation of a project funded by the Global Environment Facility and the World Bank. The project, El Proyecto de Energías Renovables en Mercados Rurales (PERMER, renewable energy in dispersed rural markets), aims, among other objectives, to provide power to isolated rural areas in a sustainable manner, using renewable sources. The most recent policy on renewable energy was established at the beginning of 2010, where Argentina had implemented feed-in tariffs granting power purchase agreements (PPA) for renewable energy. PPA s are obtainable from government-sponsored auctions. 3 Legislation on small hydropower The small hydropower action plan outlined by the National Directorate for Promotion (DNPROM) of the Ministry of Energy basically comprises: A survey of the facilities in operation and out of service, as well as those possible to be refurbished, and of public irrigation works that can be equipped with generating units. A search for new sites and to select a methodology for estimating total theoretical potential of regions and basins. Compilation, review, and proposal of a reformulation of the provincial legal regimes of water, environment and energy, in agreement and collaboration with governments and provincial agencies. An analysis of the profitability of small hydropower in isolated markets, the development of case studies and a roadmap of projects related (or not) to the Clean Development Mechanism (CDM). Identification and management of public and private financing lines for the execution of the technical and economically feasible works. The Energy Department's Office is currently bound to encourage the construction of the 116 micro-hydro plants mentioned above. The Government considers several possibilities to avoid an energy crisis to impact the economic growth. One strategy is designed to further develop the country's water resources through micro-hydro facilities, which individually have a generating capacity of up to 30 MW. Financial capacity is a key element to consider, particularly in the case of private investors looking for commercial opportunities in the small hydropower sector. Studies show that in order to encourage private initiatives, financial mechanisms are essential as they allow the collection of long-term loans at rates appropriate to the realities of such projects. Furthermore, it will be necessary to implement a system of guarantees that awards credits to private investors so that they are not inhibited by other commercial arrangements. At this point, the intervention of the federal, provincial and/or municipal state to facilitate and manage credit is needed. Complementary to this point, there is a need of an adequate remuneration system for the energy sold by small hydropower. When deciding the tariff structure of small hydropower, it will be convenient to take into account the environmental benefits and the social cost of externalities, both affecting the company but which are not incorporated yet by the generators. 6 Argentina, which has a weak penetration of renewables in the national electricity supply, opted for the regulatory mechanism of quotas for grid access. This system is advantageous for states with funding problems but does not ensure private investment. Barriers to small hydropower development Argentina has great small hydropower potential, however, a number of very diverse barriers hinder its realization, as in other countries. Hydropower is considered the most promising technology for national development, followed by wind, then solar and biomass. There are political constraints and structural limitations within the governmental agencies which are responsible for establishing policies that provide solutions to these problems. It is necessary to apply instruments that help formulate and implement an energy policy that includes renewable energy. At the moment the regulatory framework remains insufficient. Foreign investors perceive high risks and a lack of incentive based on the limited availability of local finance. Local finance is hindered by the limited number of local banks and the lack of liquidity experienced in commercial banks. Furthermore, the difficulty in securing capital at reasonable costs in the short term strongly hinders the volume of investment, despite the countries resource potential. 3 It is necessary to acknowledge that programmes like GENREN are being implemented, in which the generator is not paid a premium but a guaranteed price for the energy generated in order to provide a more reasonable rate of profit. There is a specific need to update the incentives posed by Law It is not easy to meet the target to 3
