Combined cycle power plant (PLTGU) is the combination of both gas power plant (PLTG) and steam-electric power plant (PLTU). PLTGU works by using the heat from flue gas produced by PLTG to create steam which is then transformed into a working fluid in PLTU. One of Indonesia Power''s PLTGU is located right in Semarang,
Binary cycle power plants are a type of geothermal power plant that generates electricity by utilizing low-temperature geothermal resources. Unlike traditional geothermal power plants, which require high-temperature resources of around 300°C or more, binary cycle power plants can operate at temperatures as low as 50°C.
Suoh Geothermal Power Plant is a 500MW geothermal power project. It is planned in Lampung, Indonesia. According to GlobalData, who tracks and profiles over 170,000 power plants worldwide, the project is currently at the announced stage. It will be developed in a single phase.
In a study of a stand-alone STE power plant (i.e. not SGHEPP) that is relevant to the present research due to its use of a combined cycle, Al-Sulaiman et al. [15] analyzed a solar power plant that used a steam Rankine topping cycle and a binary bottoming cycle.
Abstract. This chapter discusses integrated power plant systems that consist of either different types of geothermal energy conversion systems or some type of geothermal plant combined with at least one other different source of energy. The former are called "combined systems," and the latter are called "hybrid systems.".
