Name and Location
Hussein thermal power station (HTPS) – power generation project, Zarqa, Jordan.

Client
ACWA Power.
The proposed project will be operated and maintained by the Central Electricity Generating Company (Cegco), with the output energy being supplied to the National Electricity Power Company (Nepco), of Jordan, under a 25-year power purchase agreement.

Project Description
The proposed project involves the development of a new 485 MW gas-fired power plant within the existing landholding of the HTPS, in Zarqa, Jordan.

The original HTPS heavy fuel oil plant, stopped operating in December 2015 and will be decommissioned gradually between December 2016 and March 2019, under a separate contract.

This period of decommissioning will coincide with the construction and operational phases of the proposed project.

Owing to the available space in the HTPS landholding, the proposed plant will be built entirely on undeveloped land within the existing boundary, but will operate as a standalone facility. The project will comprise one power block, consisting of three gas-turbine generators, three heat recovery steam generators and one steam turbine generator.

Natural gas will be used to operate the HTPS and light distillate oil will be used as backup.
The HTPS will be equipped with six stacks, one for each gas turbine generator and one for each heat recovery steam generator. The proposed stack height for the heat recovery steam generator will be 60 m, while the height of the bypass stack will be 45 m.

Dry air-cooled condensers will be used for condensation of the steam from the steam turbine generator, considerably reducing the power station’s demand for raw water. The air-cooled condensers operate on direct cooling by air only, which does not result in water losses because of evaporation or drift.

Raw water supply to the plant will be sourced from a pipeline that will be built by the Water Authority of Jordan (WAJ), based on a water supply agreement. The project will also install three new deep-water wells (450 m to 500 m deep) on site, in case of an emergency.
The plant will operate on a zero liquid discharge basis and will, therefore, not discharge any treated or untreated wastewater effluents off-site. All treated wastewater effluent will either be reused, irrigated or evaporated.

Natural gas will be supplied by Nepco through a new subsurface gas pipeline connection to Jordan’s main gas pipeline, which is about 600 m to the south-east of the project boundary. No land acquisition will be required.

Backup will be delivered using an existing fuel oil pipeline from the adjacent petrochemical refinery.
The WAJ will install a new water pipeline from the local main line. Construction will be undertaken beneath existing roads and no land acquisition will be required.
The evacuation of electric power generated by the facility will be through the existing 132 kV substation, owned and operated by Nepco and located within the existing HTPS landholding.

A new 40 m access road will be built from the plant to the existing local road to the north of the project.
