Abstract
The Integrated coal Gasification Combined Cycle (IGCC) is a highly effective power generation system where a gas turbine is operated with gasified coal in a gasifier. The NAKOSO IGCC Demonstration Plant was constructed by Clean Coal Power R&D Co., Ltd. (CCP) and CCP had been conducting the various tests for commercialization since September 2007. The Demonstration Project finished in March 2013. CCP was absorbed by Joban Joint Power Co., Ltd. on April 1st 2013. The IGCC plant has been called Nakoso Power Station unit No.10 and has been operated as a commercial plant. In 2013, the consecutive operation hours recorded 3,917 hours which was much longer than the previous record and was considered to be the world record as the IGCC at the moment. The 2013 fiscal year's capacity factor was about 50%. In 2014, it was begun to use coal other than plant-designed coal. Tokyo Electric Power Company (TEPCO) has been advancing the plan to construct two 500MW-class IGCC plants in Fukushima prefecture. The one will be located at TEPCO's Hirono Power Station and another will be located at Nakoso Power Station. Joban Joint Power has been cooperating in the Nakoso project. The technologies acquired by the commercial operation will be provided for the project. Joban Joint Power will keep supporting the project positively as much as possible. This report describes the commercial operation condition etc. of Nakoso Power Station unit No.10 of Joban Joint Power Co., Ltd. from 2013FY to 2014FY.
