Diesel Plant Retrofitting Options to Enhance Decentralized Electricity Supply in Indonesia

Research output: Contribution to conferencePaper


Over the last 20 years, the government of Indonesia has undertaken an extensive program to provide electricity to the population of that country. The electrification of rural areas has been partially achieved through the use of isolated diesel systems, which account for about 20% of the country's generated electricity. Due to many factors related to inefficient power production with diesels, theNational Renewable Energy Laboratory, in conjunction with PLN, the Indonesian national utility, Community Power Corporation, and Idaho Power Company, analyzed options for retrofitting existing diesel power systems. This study considered the use of different combinations of advanced diesel control, the addition of wind generators, photovoltaics and batteries to reduce the systems' overall costand fuel consumption. This analysis resulted in a general methodology for retrofitting diesel power systems. This paper discusses five different retrofitting options to improve the performance of diesel power systems. The systems considered in the Indonesian analysis are cited as examples for the options discussed.
