Abstract
Wayang Windu geothermal power station, owned and operated by Star Energy Geothermal (Wayang Windu) Limited, has been operating its first unit (Unit 1) from 1999. Although construction of the second unit (Unit 2) was also scheduled at the same time as Unit 1, it was suspended due to the economy crisis. At that moment, the civil and architectural works including all equipment foundations were completed.
After a decade, the Unit 2 construction was resumed. It was not just a recommencement of the suspended works; it also involved some design improvements on the performance and operability under the restrictions of the existing constructs and materials. This paper introduces representative items of those improvements.
The construction of Unit 2 was completed ahead of the original schedule and the commercial operation started from February 2009 with producing more than the target gross output of 117MW.
