Indonesia is one of Asia’s fastest growing economies in terms of energy consumption. With a steadily growing population of nearly 270 million and an increasing rate of urbanization, there is significant need for a reliable and guaranteed supply of power throughout the archipelago. In recent years, the country has been successful in increasing installed capacity and investments in infrastructure to both improve the reliability and efficiency of the main grids such as the Java-Grid and increase electrification of the small grids. In this specific case, Wärtsilä’s flexible baseload power plant with superior internal combustion engine technology and flexibility provides the efficiency and reliability required for supporting this portion of the Java-Bali grid. Its low emission capability and reduced carbon footprint as compared to inflexible generation also supports Indonesia’s path to a cleaner future.
