The Gas and Power Group of China’s oil giant CNOOC has reportedly commissioned a 460 MW gas-fired combined cycle cogeneration plant at the Zhongshan Jiaming Hengmen Power Plant (pictuerd) as part of its phase II expansion.

Commercial operations began after a 168-hour full-load trial, contractor Power Construction Corporation of China reportedly announced. The unit is the third to be commissioned under the expansion plan, while a fourth is due to commence commercial operations this month. The turbines are understood to be GE 9F-type.

Once the second-phase of the project is fully commissioned the total installed capacity is expected to top 1 GW with annual generation exceeding 5 TWh.

Mayor Li Qihong has apparently called for new development of a third-phase project, as part of a plan that will make Zhongshan a power centre in western China’s Guangdong province.
