Hassyan coal-fired power plant is a 2.4GW ultra-supercritical (USC) power plant under construction in Saih Shuaib, Dubai, United Arab Emirates (UAE). It is the first coal-fired power project in the Gulf Cooperation Council (GCC) region.

The $3.4bn independent power producer (IPP) project broke ground in November 2016. It is being developed with four 600MW ultra-supercritical coal power units in the first phase.

The four units are expected to come online in 2020, 2021, 2022, and 2023, respectively.

The power plant will be owned and operated by Hassyan Energy Company, a joint venture between Dubai Electricity and Water Authority (DEWA, 51%) and the consortium of ACWA Power, Harbin Electric, and the Silk Road Fund (jointly 49%).

Saudi Arabia-based ACWA Power holds 26.95% stake in the project, while China’s Harbin Electric and Silk Road Fund own 14.7% and 7.35% interests, respectively.

The Hassyan coal power project is in line with UAE Clean Energy Strategy 2050 to diversify its energy mix to include 44% renewable energy production, 38% gas power generation, 12% coal power generation, and 6% nuclear power generation capacity by 2050.

The 2.4GW power plant is expected to generate enough electricity to power approximately 250,000 households and expand Dubai’s current grid capacity by 25%.

Hassyan coal power plant make-up

The Hassyan power plant will comprise four ultra-supercritical coal-fired generating units of 600MW capacity each.

Each unit will be equipped with an ultra-supercritical boiler, steam turbine, and a generator from GE.

The USC technology will enable power generation at a higher steam temperature and pressure compared to conventional coal-fired plants, resulting in lower operating costs and stack-emissions.

The plant will be equipped with advanced electrostatic precipitators (ESP) and seawater flue gas desulphurization (SWFGD) system to reduce the NOx, SOx, and particulate emissions.

Further, the plant is designed to accommodate carbon capture installations in the future.

The electricity generated by the power plant will be fed into the existing 400kV electricity transmission network from an on-site 400kV new substation.

Coal supply and handling

The Hassyan power plant will use imported coal from EDF Trading, under a long-term supply agreement.

The project includes an offshore floating coal handling facility along with barges for coal transshipment, an onshore jetty for both coal and ash, and an onshore coal bulk handling facility along with a coal storage facility for 45 days.

Louis Dreyfus Ports and Logistics will manage the coal handling and transshipment facilities for the power plant under a contract awarded in October 2015.

Power purchase agreement

DEWA will off-take the entire electricity output of the plant under a 25-year power purchase agreement (PPA) signed in June 2015.

Financing for the Hassyan coal-fired power plant

The financiers for the $3.4bn coal-fired power project include the Industrial and Commercial Bank of China (ICBC), Bank of China, Agricultural Bank of China (ABC), China Construction Bank (CCB), Silk Road Fund, First Gulf Bank, Union National Bank, and the Standard Chartered Bank.

Contractors involved in the Hassyan clean coal power project

Harbin Electric International and General Electric (GE) were awarded the engineering, procurement, and construction (EPC) contract for the Hassyan thermal power project in June 2016.

GE is responsible for the design, supply, and installation of boilers, steam turbine generators, and advanced emissions control systems for the project.

Huaye Steel Structure (HYSS) was subcontracted by GE for the steel fabrication of the boiler support system for the four generating units of the plant in August 2016.

NOMAC, a wholly-owned subsidiary of ACWA Power, is the operations and maintenance (O&M) contractor for the project.

ACES-Dubai carried out geotechnical investigation for the Hassyan coal power project under a contract awarded by Consolidated Contractors Company (CCC) and Nepti in October 2016.
