Indonesia's Largest and Most Efficient Coal-fired Power Plant Inauguration
-- Supercritical Pressure Plant for Paiton Thermal Power Station --

The inauguration ceremony of the plant took place today at the plant site. The ceremony was attended by Jero Wacik, Energy and Mineral Resources Minister of Indonesia; Shigeru Ushio, Minister, Embassy of Japan in Indonesia; Low Kian Min, President of Paiton Energy; and by many people concerned, including Koji Hiramoto, Deputy Head of Power Systems, MHI.

The project to expand the existing 1,220 MW Paiton Power Station, which Paiton Energy has been operating since 1999, began in 2008. The new 815 MW power plant was constructed at a site adjacent to two existing coal-fired power plants (units 7 and 8) within the Paiton complex, which is located some 150 kilometers southeast of Surabaya, the provincial capital of East Java. The new plant mainly consists of a steam turbine and supercritical pressure boiler. MHI manufactured and supplied the steam turbine and boiler, while installation and construction work was undertaken jointly by TOA Corporation and Mitsui & Co., Ltd. of Japan.

PT Paiton Energy is an IPP established in Indonesia in 1995. Equity is owned by Mitsui & Co., Ltd.; International Power of the UK; The Tokyo Electric Power Company, Incorporated (TEPCO); and PT Batu Hitam Perkasa of Indonesia.

Supercritical pressure coal-fired power generation provides higher generation efficiency than subcritical pressure generation and is capable of reducing coal consumption relative to power output, which results in lower carbon dioxide (CO2) emissions. Going forward MHI will continue to conduct aggressive marketing activities for high-efficiency and environmentally friendly supercritical and ultra-supercritical pressure power generation systems in Japan and abroad.
