Since the founding of the state of Timor Leste, on the 20th of May 2002, the Timor-Leste government has begun to reform society to participate in developing the people’s mentality from the worst of colonialism and prolonged war. One very important aspect in mental development is unconditional peace between society and its invaders and war enemies. So that society can improve itself, in participating in physical development, with a focus on economic cooperation in all fields, to increase the people’s economic growth. One of the physical aspects that the community is looking forward toisa source of electrical energy, which the community needs to utilize, in order to boost the family economy. So the Timor-Leste Government built high voltage network infrastructure, traveling throughout the territory of Timor-Leste. In this way, it will be easier to distribute electrical energy to the community to be used for lighting and to stimulate the family economy with various home industry activities. So two central electrical energy generators were established in Hera and Betano, known as Electricidade de Diesel de Timor-Leste, which is shortened to EDTL. So two EDTL centers were built, in Hera with 7 units of diesel engines, for generating electrical energy with a total capacity of 119 MW, and began operating in December 2011. Then the EDTL center in Betano with 8 units of diesel engines with a total capacity of 136 MW, and began operating in February 2012. Each diesel engine unit generating electrical energy at the two EDTL centers in Hera and Betano has a capacity of 17 MW perengine unit. With the construction of these two EDTL centers, the State of Timor-Leste and its people will not lack electrical energy. So that in the current era electrical energy has enormous benefits, to boost the people’s economy, through family household industrial activities, and for the nation and state, to move the wheels of the economy, through offices, hospitals, banks, ports, aeroports, hotels, figures, and also for planning small industry and industrial mega projects that are being planned in the southern part of Timor-Leste, namely 3 pillars, consisting of Supply Base, Oil Refinery and LNG, for community prosperity.
