Análisis de la influencia del ingreso del proyecto ciclo combinado 318 MW dentro de la matriz eléctrica del Ecuador

Abstract

Currently the electric Ecuadorian system to meet the national demand has mainly used generation hydroelectric and thermoelectric, the latter made up of units with gas and steam turbines among the cheapest on the type of fuel they use. Both technologies are used to generate separate electricity. There is the possibility to be exploited more efficiently, using the heat contained in the turbine exhaust gas to produce steam in heat recovery boilers and driving this product at high pressure into a steam turbine, thus producing additional power without incurring consumption of fuel, forming in this way a combined cycle plant. Thanks to the interest of the national Government to increase the national energy supply and that it is of low production costs, combined cycle power project is underway in the central Termogas Machala, located in the sector of Bajo Alto in the province of El Oro. In this plant are currently operating two gas turbine in open cycle to which will be added a third gas turbine of similar characteristics and cycle will close with three heat recovery boilers and their respective steam turbine. With the implementation of this type of power plant, pioneer in the country, will be to increase energy supply in additional 187 MW, completing 318 MW which will produce all the combined cycle. In addition to the above, will reduce production costs of the new plant at 36%, as well as to contribute positively to the improvement of the energy matrix of Ecuador to move with their generation at low cost, more expensive generation technologies manner saving the country 1,070,000.00 US dollars for the operation of the third gas turbine plus steam turbine.
