Programa de eficiência energética e sustentabilidade no Metrô-DF

Abstract

The purpose of the Application Project was to propose a Program to increase energy efficiency and promote the sustainability of the Metropolitan Company of the Federal District (METRÔ-DF), composed of actions to be adopted, chosen through viability analysis, according to Process Map defined by group and the use of the 5W2H tool, wich aimed to reduce energy consumption from the electric energy concessionaire - Companhia Energética de Brasília – CEB. Following analysis of the sector sixteen actions were identified, of which ten were considered applicable, representing an eleven-million saving (R$ 11,764,827.13 – eleven million seven hundred and sixty-four thousand, eight hundred and twenty-seven reais and thirteen cents), 25.31% of the annual electricity cost. The actions are: lamp replacement in trains; signal lamp replacement; rectifier transformer in traction substations switch off; auxiliary transformer in traction substations switch off; power plant implementation at the Operational Administrative Complex; automatic escalator system implementation; lamp replacement in the passenger stations; tile replacement of the Maintenance Complex; innovation activities promotion in the Metro Innovation Lab; obtaining exemption or reduction of taxes and fees charged on electric bills. For the viability calculation, sustainable technological solutions, deployment cost variables, maintenance and operation cost, expected energy savings and the time required to recoup the funds expended were considered. These actions will make the high expenses of METRÔ-DF possible to reduce, which is a public company dependent on the local government.
