The surface waters generated in our territory represent about 50% of the total resources in South America and 11% of the world resources.<\/p>\n\n\n\n<p>Here at Cemig, we make use of water resources to generate electricity through our hydroelectric power plants, whose raw material is 100% water. This water used to generate energy is not consumed: it passes through the turbines and returns immediately to the river, following its natural course.<\/p>\n\n\n\n<p>The&nbsp;<strong>reservoirs<\/strong>&nbsp;built to accumulate water to generate&nbsp;<strong>electricity<\/strong>&nbsp;help to regulate water availability in the river basin. They provide higher flows during periods of drought or water crisis and minimize flooding during the rainy season.<\/p>\n\n\n\n<p>Weather forecasting and constant&nbsp;<strong>monitoring<\/strong>&nbsp;of rain and water level in reservoirs and rivers are fundamental for managing the storage volume of hydroelectric power plants. To assist us, we have a wide network of automatic measuring stations, which send data in real time so that the planning of the gates operation and power generation is optimized.<\/p>\n\n\n\n<p>Apart from the advantages of regularization, the water stored in the reservoir can also be used for other purposes such as:<\/p>\n\n\n<ul>\n<li>Human and Industrial Supply;<\/li>\n<li>Irrigation;<\/li>\n<li>Navigation;<\/li>\n<li>Fishing and Aquaculture (rearing fish in net-tanks);<\/li>\n<li>Tourism and Leisure, offering benefits to the river basin.<\/li>\n<\/ul>\n\n\n<p>To promote the&nbsp;<strong>sustainable use<\/strong>&nbsp;of water, our technical team is constantly seeking improvement through specializations, master\u2019s and doctorate degrees, training, participation in national and international seminars and in Research and Development \u2013 R&amp;D projects with ANEEL.<\/p>\n\n\n\n<div style=\"height:48px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Water Resources Management: How is it Done?<\/h2>\n\n\n\n<p>In Brazil, since the establishment of the National Water Resources Policy and the National Water Resources Management System with the publication of Law No. 9,433 in 1997, water use has been discussed in collegiate Water Resources Management Bodies with the participation of public authorities, civil society and users.<\/p>\n\n\n\n<p>The&nbsp;<strong>water resources<\/strong>&nbsp;<strong>management&nbsp;<\/strong>involves a set of actions aimed at regulating its use, control and protection, in accordance with the relevant legislation and regulations. This legislation is elaborated by the legislative and executive powers, and by collegiate and deliberative bodies that make up the National and State Water Resources Management Systems.<\/p>\n\n\n\n<p>Due to its use of water, Cemig participates in an active and strategic way in the formulation of laws and norms of the Water Resources Management Policy and System. The company is present in the technical discussions of the main collegiate bodies for the formulation of rules and the establishment of guidelines, such as:<\/p>\n\n\n<ul>\n<li>the National Water Resources Council (CNRH);<\/li>\n<li>the State Water Resources Council (CERH);<\/li>\n<li>the Federal and State River Basin Committees;<\/li>\n<li>the Technical Chambers;<\/li>\n<li>the Working Groups, especially those dealing with the preparation of master plans for water resources, the regulations on Granting and Collection for the Use of Water Resources.<\/li>\n<\/ul>\n\n\n<p>Therefore, we represent the users of&nbsp;<strong>water resources<\/strong>&nbsp;for hydroelectric power generation in the State Water Resources Council in the State of Minas Gerais (CERH\/MG), in 04 river basin committees of the Federal Government and 20 river basin committees of the State Government.&nbsp;&nbsp;<\/p>\n\n\n\n<p>In our\u00a0<a href=\"https:\/\/www.cemig.com.br\/en\/wp-content\/uploads\/sites\/2\/2026\/04\/poicy-of-water-resources-of-cemig-1.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Water Resources Policies<\/a>, learn more about how water is managed and conserved in our energy generation processes.<\/p>\n\n\n\n<div style=\"height:48px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">River Basin Committees<\/h2>\n\n\n\n<p>The River Basin Committees are management groups composed of representatives of the three levels of government (federal, state and municipal), water users and civil society. It is through democratic discussions and negotiations that these committees assess the real and different interests in river basin water uses.<\/p>\n\n\n\n<p>The main decisions made by the committee are:<\/p>\n\n\n<ul>\n<li>Approve and monitor the development of the Basin Water Resources Master Plan, which gathers strategic information for water management in each basin;<\/li>\n<li>Mediate conflicts for the use of water (in the first administrative instance);<\/li>\n<li>Establish mechanisms and suggest charging amounts for the use of water.<\/li>\n<\/ul>\n\n\n<div style=\"height:48px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Monitoring<\/h2>\n\n\n\n<p>In addition to water resources management, we promote information campaigns on aspects that may interfere with\u00a0<strong>water quality<\/strong>\u00a0and\u00a0<strong>energy generation<\/strong>, such as\u00a0<a href=\"https:\/\/www.cemig.com.br\/en\/news\/the-golden-mussel-understand-why-this-invading-species-is-dangerous-to-nature\/\">golden mussels<\/a>, cyanobacteria, aquatic macrophytes, reservoir siltation, iron-bacteria, among others.<\/p>\n\n\n\n<p>In all our plants, we also carry out the control of inorganic and organic effluents and the drinking water used by employees. We currently have a&nbsp;<strong>Water Quality Management Center<\/strong>&nbsp;<strong>\u2013 NGQA<\/strong>, which has worked to make the monitoring suitable and uniform, so that the data obtained can be used by the Company itself in all its units and also by our partners, with the purpose of making a spatial and temporal assessment of the water in the reservoirs.<\/p>\n\n\n\n<div style=\"height:48px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Sedimentary Monitoring<\/h2>\n\n\n\n<p>We operate fluviosedimentometric stations with the purpose of monitoring the intake and deposition of sediments in the reservoirs, aiming at:<\/p>\n\n\n<ul>\n<li>Quantify and characterize sediments brought by rivers in some places of interest;<\/li>\n<li>Estimate useful life of existing reservoirs and future developments;<\/li>\n<li>Meet the environmental requirements for the release of Operating License \u2013 OL;<\/li>\n<li>Alert the competent bodies about the degradation of the river basin;<\/li>\n<li>Subsidize the actions of the Hydrographic Basin Committees and simultaneously comply with ANA\/ANEEL Joint Resolution No. 3, from August 10, 2010.<\/li>\n<\/ul>\n\n\n<p>This monitoring currently has stations located in different river basins, which operate in a detailed regime from where solid discharge measurements are often performed, by means of sampling techniques that allow, through their analysis, the calculation of the transported volume.<\/p>\n\n\n\n<p>This sediment monitoring is currently carried out in 86 stations located in the vicinity of each of our Hydroelectric Power Plants (HPPs) and Small Hydroelectric Plants (SHPs).<\/p>\n\n\n\n<div style=\"height:48px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Hydrometeorological Monitoring<\/h2>\n\n\n\n<p>We have started the operation of the hydro-meteorological network with the purpose of assessing the hydroelectric potential of Minas Gerais. Due to the growing development of the electrical sector, it was necessary to guarantee the operation of the network to ensure the generation of reliable hydrologic series, improving the planning of the expansion of the sector, in addition to ensuring steady energy.&nbsp;&nbsp;<\/p>\n\n\n\n<p>Currently, Cemig operates a hydro-meteorological network with 583 monitoring points, of which 232 are rainfall, 224 are waterways, 74 are reservoir and river levels, and 53 are weather stations, which monitor rainfall, temperature, air humidity, wind speed and direction, solar radiation and atmospheric pressure. These stations are distributed in strategic locations in the states of Minas Gerais, Goi\u00e1s, Rio de Janeiro, Esp\u00edrito Santo and Santa Catarina, and their data is received in real time at the Company\u2019s headquarters in Belo Horizonte.<\/p>\n\n\n\n<p>To promote the sustainable use of water, our technical team is constantly seeking improvement through specializations, master\u2019s and doctorate degrees, training, participation in national and international seminars and in Research and Development \u2013 R&amp;D projects with ANEEL.<\/p>\n\n\n\r\n    <section\r\n    class=\"bloco-tabela\"\r\n    id=\"tabela_69f4ea60252ae-wrapper\"\r\n    data-table-id=\"tabela_69f4ea60252ae\"\r\n    data-page-length=\"20\"\r\n    data-paging=\"false\"\r\n    data-translate=\"https:\/\/www.cemig.com.br\/en\/wp-content\/themes\/cemig-theme\/assets\/plugins\/dataTables\/pt-BR.json\"\r\n    data-mobile-max-width=\"569\"\r\n  >\r\n    <div class=\"container\">\r\n      <div class=\"row\">\r\n        <div class=\"col-12 mx-auto\">\r\n          <div class=\"tabela-wrapper\">\r\n            <table id=\"tabela_69f4ea60252ae\" class=\"table \">\r\n                              <thead>\r\n                  <tr>\r\n                                          <th scope=\"col\">N\u00ba<\/th>\r\n                                          <th scope=\"col\">Title<\/th>\r\n                                          <th scope=\"col\">Main goal<\/th>\r\n                                          <th scope=\"col\">Institutionsninvolved<\/th>\r\n                                          <th scope=\"col\">Cordinator<\/th>\r\n                                          <th scope=\"col\">Period<\/th>\r\n                                      <\/tr>\r\n                <\/thead>\r\n              \r\n              <tbody>\r\n                                                      <tr>\r\n                                              <td data-label=\"N\u00ba\">\r\n                          Ru0026amp;D 599                        <\/td>\r\n                                              <td data-label=\"Title\">\r\n                          Ecological Processes: Development of New Ecotechnologies for Diagnosis and Environmental Processes (PROECOS)                        <\/td>\r\n                                              <td data-label=\"Main goal\">\r\n                          Evaluate ecological processes to develop new ecotechnologies for assessing environmental quality, based on knowledge of key ecosystem processes linked to the functional integrity of hydrographic basins and hydroelectric reservoirs.

The surface waters generated in our territory represent about 50% of the total resources in South America and 11% of the world resources. Here at Cemig, we make use of water resources to generate electricity through our hydroelectric power plants, whose raw material is 100% water. This water used to generate energy is not consumed: it passes through the turbines and returns immediately to the river, following its natural course. The&nbsp;reservoirs&nbsp;built to accumulate water to generate&nbsp;electricity&nbsp;help to regulate water availability in the river basin. They provide higher flows during periods of drought or water crisis and minimize flooding during the rainy season. Weather forecasting and constant&nbsp;monitoring&nbsp;of rain and water level in reservoirs and rivers are fundamental for managing the storage volume of hydroelectric power plants. To assist us, we have a wide network of automatic measuring stations, which send data in real time so that the planning of the gates operation and power generation is optimized. Apart from the advantages of regularization, the water stored in the reservoir can also be used for other purposes such as: Human and Industrial Supply; Irrigation; Navigation; Fishing and Aquaculture (rearing fish in net-tanks); Tourism and Leisure, offering benefits to the river basin. To promote the&nbsp;sustainable use&nbsp;of water, our technical team is constantly seeking improvement through specializations, master\u2019s and doctorate degrees, training, participation in national and international seminars and in Research and Development \u2013 R&amp;D projects with ANEEL. Water Resources Management: How is it Done? In Brazil, since the establishment of the National Water Resources Policy and the National Water Resources Management System with the publication of Law No. 9,433 in 1997, water use has been discussed in collegiate Water Resources Management Bodies with the participation of public authorities, civil society and users. The&nbsp;water resources&nbsp;management&nbsp;involves a set of actions aimed at regulating its use, control and protection, in accordance with the relevant legislation and regulations. This legislation is elaborated by the legislative and executive powers, and by collegiate and deliberative bodies that make up the National and State Water Resources Management Systems. Due to its use of water, Cemig participates in an active and strategic way in the formulation of laws and norms of the Water Resources Management Policy and System. The company is present in the technical discussions of the main collegiate bodies for the formulation of rules and the establishment of guidelines, such as: the National Water Resources Council (CNRH); the State Water Resources Council (CERH); the Federal and State River Basin Committees; the Technical Chambers; the Working Groups, especially those dealing with the preparation of master plans for water resources, the regulations on Granting and Collection for the Use of Water Resources.
