The SCR system installed on Ninghai Power Plant Unit 4 of the Beijing Guohua Electric Power Corporation — one of China's most influential power utilities — is the first NOx removal system implemented on the Chinese mainland through Chinese capital investment. This SCR system was implemented as a project set up between Babcock-Hitachi K.K. with Hitachi, Ltd. as the main contractor and Zhejiang University Energy Technology Co., Ltd. as a local partner. An order for the SCR system was accepted in January 2005, all items in the contract specifications (including DeNOx performance) were satisfied, and trial operation was completed in November 2006. In response to growth in the Chinese SCR business, Babcock-Hitachi has transferred SCR technology to three Chinese manufacturers. At the end of September 2008, the Hitachi Group took the lead in the Chinese SCR market with orders received for SCR system — based on that installed at Ninghai Power Plant Unit 4 — for 38 power plants (with a total capacity of about 23,000 MW) combining SCR system and catalysts.
