Control in geothermal station!

Yokogawa is to supply the control system for unit 5 of the Kamojang geothermal power station in Indonesia. The order for this project was received through Tokyo Denki Sangyo Co., Ltd., a Yokogawa sales agent, and was placed by Fuji Electric Co., Ltd., which is responsible for manufacturing and delivering the unit's steam turbine and generator.

This geothermal plant is owned and operated by PT. Pertamina Geothermal Energy (PGE), the geothermal arm of the state-run oil and gas company, Pertamina, and is located in Garut, a city situated approximately 40 km from Bandung City, West Java, Indonesia. Unit 5 will have a 35 MW power generation capacity, and its construction is scheduled to be completed by July 2015, whereupon it will be commissioned and enter service.

For the monitoring and control of unit 5's steam turbine and auxiliary facilities, Yokogawa's subsidiaries Yokogawa Engineering Asia and Yokogawa Indonesia will supply the CENTUM(R) VP integrated production control system, InsightSuite(R) AE plant asset effectiveness optimisation services, PRM(R) plant resource manager, Exaquantum(tm) plant information management system (PIMS), and a plant operation training simulator. In addition to being responsible for the delivery of these systems, these companies will provide support during the engineering and commissioning phases.

Unit 4 at this plant also uses a Yokogawa integrated production control system, CENTUM(R) CS 3000. Completion of the current project will bring to 11 the number of control systems that Yokogawa has provided for geothermal power plants in Indonesia.

Geothermal energy can generate a stable supply of electricity day and night, and in all weather conditions. Since no carbon dioxide is emitted, it is regarded as an attractive alternative to fossil fuels. Indonesia has the world's largest geothermal energy resources and is planning many additional projects to exploit these resources.

To grow its industrial automation and control business and contribute to the realisation of a sustainable society, Yokogawa is targeting renewable energy fields such as geothermal power. As such, the company will be seeking to expand the provision of its solutions in Indonesia and other geothermal resource-rich countries.
