Reducing emissions in Chile by promoting the use of combined heat and power plants in industry and commerce
Title: Reducing emissions in Chile by promoting the use of combined heat and power plants in industry and commerce
Commissioned by: German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB) as part of the International Climate Initiative (IKI)
Lead executing agency: Chilean Ministry of Energy, Chilean Agency for Energy Efficiency (AChEE)
Overall term: 2015 to 2019
Fossil fuels, mainly imported coal, are used to generate over 65% of Chile’s electricity. Not only does this result in the release of significant volumes of harmful greenhouse gases, it also means Chile is dependent on imports of these fossil energies.
There are currently only a few examples of efficient cogeneration in Chile. A pilot project implemented in three public hospitals showcased the technical and economic feasibility of combined heat and power (CHP). However, widespread use of CHP, particularly in attractive fields of application in industry and commerce, has not yet taken off. According to a preliminary analysis of potential carried out by the Chilean Agency for Energy Efficiency (AChEE), the introduction of CHP plants in industry could potentially generate 18 million megawatt hours of energy per year (electricity and heat) and make annual savings of 4.2 million tonnes of CO2 emissions.
Small and medium-sized CHP plants are increasingly used in Chilean industry and commerce. The standardisation and regulatory framework for CHP plants is improved and the technical competence of Chilean specialist institutions is broadened.
The project will be implemented in close cooperation with the Chilean Ministry of Energy and the National Agency for Energy Efficiency (AChEE). It analyses the market potential of new CHP solutions, introduces new technologies and trains local skilled workers in quality assurance for CHP plants installed in Chile. Experience gained in Chile will be shared with neighbouring countries, including Argentina, Bolivia, Peru, Colombia and Ecuador, in order to incentivise similar cogeneration projects and in so doing help further reduce greenhouse gas emissions.
Experience from the operation of existing CHP plants in Chile, including the results of the aforementioned pilot project in three public hospitals, is to undergo in-depth evaluation by the institutions involved in the project (Ministry of Energy, Ministry of Health, Agency for Energy Efficiency and the Superintendence for Electricity and Fuel) during the first year of the project term before being incorporated into updates of legal texts, regulations and building codes. National and international advisors provide support with preparing and adapting international regulations to the Chilean context.
The Chilean Ministry of Energy and downstream institutions are provided with continuous advisory services on ongoing development of the underlying legal framework in the field of cogeneration. This also includes targeted assistance with the development of a potential support framework.
The economic potential of cogeneration in industry and commerce is analysed in order to establish a precise picture of marketable applications. During the first year of the project term, an existing study of CHP potential dating from 2010 is to be updated and expanded in collaboration with the Ministry of Energy, the Ministry of the Environment, the Centre for Innovation and Promotion of Sustainable Energy (CIFES) and the Agency for Energy Efficiency (AChEE). Based on this analysis, more detailed studies covering a range of different sectors will be drawn up, including the chemical and food processing industries, hotels, shopping centres and supermarkets, as well as public facilities.
The analysis also includes examination of the potential for using innovative cogeneration technologies to supply heat in the south of the country. In particular, this will involve exploring and promoting the potential of biogas for local heating networks and biomass cogeneration for district heating systems from the point of view of climate and air pollution.
