Kais Combined-Cycle Power Plant

The Kais power project, also known as the Khenchela power project, is a 1,266MW combined-cycle gas-fired power station under construction in the Khenchela province of Algeria.

Societe Algerienne de Production d’Electricite (SPE), a subsidiary of Algeria’s state-owned electricity and gas utility Sonelgaz, is the owner and developer of the project.

Kais and Mostaganem are two of the six new combined-cycle power projects that Sonelgaz had decided to build with a total investment of £2.4bn ($4bn) in 2013, in order to meet the rising demand for electricity in the North African country.

While the key contracts were awarded in 2013, the main construction works on the Kais power project were started in February 2017.

The boiler module for the facility was installed in August 2021, with commissioning expected by December 2022.

Kais power project location

The Kais gas-fired combined-cycle power plant is located 22km away from the Khenchela city, in the Khenchela province in north-eastern Algeria.

Kais combined-cycle-power plant make-up

The Kais gas-fired power station will comprise two combined-cycle power blocks, each equipped with two General Electric (GE) 9F series gas turbines, two heat recovery steam generators (HRSG), and two steam turbine generators along with air coolers and other associated facilities.

Construction equipment for the Kais power project

The major construction equipment deployed at the project site included Demag CC2800-1 and 2400-1 tailing cranes, a Demag AC259 support crane for lifting and installation activities, as well as  Demag CC2800 and CC1800 crawler cranes.

Power evacuation

The electricity generated by the Kais gas-fired combined-cycle power plant will be evacuated to the national electricity transmission network via a 400/200kV substation.

Contractors involved

GE received a contract to supply gas and steam turbines along with generators for Algeria’s six new combined-cycle power plants including Kais in September 2013.

A joint venture of South Korean companies GS Engineering and Construction and Daelim Industrial was awarded the engineering, procurement and construction (EPC) contract for the Kais combined-cycle power plant in February 2014.

Inerga, a subsidiary of Sonelgaz, was engaged in civil engineering works, while  Sinoconst Group (formerly Chinese CMIIC Engineering and Construction Corporation) won the bid for the construction of the project in October 2016.
