Outline:
Gresik Steam Power Plant Units 3 and 4 are steam power generating facilities with each possessing rated output of 200 MW. Construction of these units was financed by yen loan and Unit 3 started its commercial operation in August 1988 and Unit 4 in October in the same year. This power plant also has output from Units 1 and 2, which were also constructed by yen loan, and three combined cycle units. This plant reaches 2,178 MW, and plays a key role in Java-Bali power system.

However, approximately 16 years have passed since the construction of Units 3 and 4 and some of the facilities have been deteriorated over time. In particular, the turbines have deteriorated faster than usual due to the salt carried in by steam. In September 2003, maximum available operating output declined to 162 MW in Unit 3 and 172 MW in Unit 4.

This project is to recover output and improve plant's thermal efficiency of the existing de-rated power units. It is also expected that increase of reliability of power units operation will contribute to stable operation of Java-Bali power system.
