Gas Trapan Central

Description: The Project consists in the construction and operation of a Gas Power Plant that seeks to operate as a complement to the variability and intermittency generated by the Unconventional Renewable Energy Power Plants (NCRE). This plant will be located on land belonging to the company Enlasa Generación Chile SA, subsidiary of the Owner, adjacent to the facilities of the project "90 MW Trapan Power Generation Plant". It should be noted that this Project will not introduce modifications to the existing Plant. The Project considers two main sectors, (i) the motor sector and (ii) the storage of Liquefied Petroleum Gas (hereinafter LPG). The motor sector will consist of 12 generating units that operate with LPG, each unit will have a power of 1.72 MW, so the plant will have a total capacity of maximum generation of 21 MW, plus it is considered an elevator transformer each 2 engines (completing a total of 6 transformers) of 4.5 MVA each, 12 external radiators, 1 for each engine and 2 electrical rooms (container). Each generating unit has its own exhaust system, independent for its final evacuation. In total, 12 exhaust gases located at 8 meters each are considered. In order to store and supply the fuel required for the operation of the engines, the Project considers as a second sector an LPG storage system that includes 4 mounds of 114 m 3 each (50Ton), which will be connected to generating units using a surface gas matrix of approximately 450 meters. Additionally, a vaporizing sector is considered, whose objective is to transform from gas to gaseous state the fuel that will finally be used by the engines and 2 LPG discharge stations. This area will have pavement and sufficient turning radius so that the trucks can transit and connect to the pumping station to the LPG tanks. The fuel (LPG) will be acquired according to the generation needs of the Project, and will be provided by companies that have corresponding authorization for the transportation of this type of fuel. On the other hand, the power generated by the Power Plant will be evacuated through a Medium Voltage Line (LMT) of 23 kV through an aerial ladder channeling of only 20 meters in length, which will reach the existing Los Molinos substation, located at Inside the current Power Generation Plant 90 MW Trapén, for later delivery to the National Electric System (SEN). For the operation of the new Central, the existing and specialized labor force currently operating the 90MW Trapan Power Generation Plant is considered, therefore, no new workers will be required for this stage of the Project. On the other hand, given this operational synergy, it is contemplated to use part of the existing buildings of the Power Generation Power Plant 90 MW Trapan, for which a service contract will be established between both Owners. These facilities include: offices, hygienic services, control room, warehouses and workshops. It should be noted that the use of these buildings will not generate changes or modifications in the operation of the existing Plant, they will be maintained as they are authorized and there will not be an increase in the permitted capacities. During the development of this Environmental Impact Statement, a more detailed description of the parts, works and actions that make up the Project is provided. Next, in the following figure a referential image of the future Central Gas Trapan is presented. Objective The objective of the Project corresponds to the generation of electric power through the operation of liquefied gas (LPG) engines, as a complement to the variability and intermittency generated by the Unconventional Renewable Energy Plants. Based on this objective, the following specific objectives are derived: To build and operate a power generation plant through 12 engines in
