The 4GW Luoyuanwan coal-fired project, located near Fuzhou in Fujian province, is one of the largest coal-fired power plants under construction in China.

Guoneng (Lianjiang) Port Power Company, a wholly-owned subsidiary of Chinese state-owned Shenhua (Fujian) Energy, is developing the project in two phases of 2GW capacity each with a total estimated investment of £2.19bn ($3.08bn).

China’s National Energy Administration (NEA) approved the start of preliminary works of the Luoyanwan coal-fired power project in September 2012.

Construction on the £1.21bn ($1.7bn) phase one of the project commenced in March 2015. The first 1,000MW unit of the plant was put into commercial production in December 2021, while the second unit is expected to be operational by May 2022.

The Luoyuanwan coal-fired power plant is estimated to generate approximately eight billion kilowatt-hours (kWh) of electricity a year, after the completion of phase one.

Location and site details

The Luoyuanwan coal-fired power project is located in the Xiangong town of Lianjiang county, Fuzhou city, Fujian province, China.

The project site occupies 140ha on the south bank of Luoyuan Bay in the Kemen Port zone.

Luoyuanwan coal-fired power project details

The Luoyuanwan power plant will comprise four ultra-supercritical coal-fired units of 1,000MW capacity each.

Each unit will be equipped with a one-time intermediate reheat, single shaft, four-cylinders and four-exhaust condensing steam turbine, and a 3,100 tonnes per hour pulverised coal boiler.

Other components of the plant will include a distributed control system, a coal conveying system, as well as flue gas desulphurisation and denitrification systems.

The Luoyuanwan project also involves a 20 million tonnes per annum (Mtpa) coal storage base in phase one, which will be expanded to 30Mtpa in phase two.

Coal and water supply

The power plant receives coal from the Luoyuan Bay coal emergency reserve base through a conveyor belt system from the Port of Kemen to the plant site.

The process water for the plant is sourced from the Tangban Reservoir on the Aojiang River.

Infrastructure facilities

Other infrastructure facilities for the Luoyuanwan coal-fired power plant include 300,000t and 400,000t wharves at berths 1-3 of the Kemen Port.

The project also utilises an enclosed coal yard with a storage capacity of 100,000t at the port, along with coal conveyor belt, iron separators, and coal crushers.

Power evacuation

The electricity generated by the Luoyuanwan coal-fired thermal power plant is evacuated into the Fujian Power Grid through a 500kV power transmission line.

Contractors involved

Shanghai Power Construction won the bid for the main construction works of the Luoyuanwan coal-fired power plant in October 2014.

Harbin Electric was contracted to manufacture and supply N1000-28/600/620 model steam turbines and generators for the project.

HollySys Automation Technology was awarded a contract to manufacture and deliver a distributed control system for the coal power project in August 2016.

Strok Thermeq was contracted to supply two deaerators and accessories, while Beijing Power Equipment Group provided 35kV voltage separate phase common box equipment for the Luoyuanwan coal-fired power plant.

North China Electric Power Design Institute Engineering Company carried out the environmental impact assessment (EIA) for the project.

Qingxin Environmental Technology was engaged to deliver the flue gas desulphurisation (FGD) equipment for the project.
