Abstract
Geothermal energy is one of the environmental friendly energy to generate electricity. Heat energy in the form of steam and hot water that existed inside the earth is flowed to the surface and goes into production and generator facilities to generate electrical energy. Currently, there are many types of electricity generation for geothermal, such as separated cycle, single flash, binary cycle and combined cycle. These types of generators are power plants with a capacity of 65-110 MWe and require a large area, many wells, large facilities and of course large capital. However, there are types of power plants that can be developed in a fast time, namely Wellhead Generating Unit. In the manufacture of a Wellhead Generating Unit, steam is extracted from the well and converted to electricity at the wellhead. This type of generator can produce electricity in relatively short time and simpler equipment. Indonesia has only one example of developing a Wellhead Generating Unit (Small Scale) in the PLTP PT. Geo Dipa Energi Dieng with a capacity of 10 MWe. In addition, the following are some of the regulations governing geothermal energy in Indonesia, namely Law No. 21 of 2014 concerning Geothermal Energy, Presidential Regulation No. 3 of 2016 concerning the Acceleration of the Implementation of National Strategic Projects, Government Regulation No. 7/2017 concerning Geothermal Energy for Indirect Use, the aspect of land clearing is regulated in Law number 4/2009 concerning Minerba. The sale and purchase agreement is regulated in the Minister of Energy and Mineral Resources Regulation Number 10 of 2017 and environmental impact is regulated in the Government Regulation of the Republic of Indonesia Number 27 of 1999 concerning Environmental Impact Analysis. Enacted on May 7, 1999. From the above legislation, the Wellhead Generating Unit (Small Scale) is the same as an ordinary conventional generator, but what distinguishes only the capacity generated by this generator.
