Abstract
The life cycle inventory (LCI) of the electric power generation plays a vital role on LCIs of the industrial products. The objective of this study is to introduce life cycle assessment (LCA) method for Indonesian's electric power generation systems and to establish LCI for electricity grid mix of Indonesia, which would be databases for further LCA study. In this study, the main data are obtained from the Electricity Generating Authority of Indonesia (Perusahaan Listrik Negara, PLN), and the Independent Power Producers (IPPs) during fiscal year 1999 from April 1999 to March 2000. The result of this study could be useful for further LCA research on Indonesia.
