South Helwan supercritical power plant is a 1.95GW gas and oil-fuelled power plant being constructed in Helwan, a city situated along the Nile River, south of Cairo, Egypt.

Egyptian Electricity Holding Company (EEHC) is developing the project through its subsidiary, Upper Egypt Electricity Production Company (UEEPC). The estimated investment in the South Helwan supercritical power plant is $2.4bn.

The project is expected to become one of the biggest thermal power plants (TPP) in Egypt upon completion and is anticipated to create approximately 4,000 jobs, including 75% in construction.

Construction of the thermal power plant started in 2016 and was 93% complete as of April 2018. The plant is expected to come on-line in 2019, following the completion of reliability tests proposed to be carried out by the end of May 2019.

South Helwan supercritical power plant make-up

The South Helwan supercritical power plant is being developed in an area of approximately 276,000m2. It will be the second TPP in Egypt to generate power using supercritical boiler technology.

The plant will be equipped with three supercritical pressure steam turbine units having a capacity 650MW each, and three supercritical steam generation boilers. It will use natural gas as primary fuel and heavy fuel oil as a backup to achieve the rated capacity.

“It will be the second TPP in Egypt to generate power using supercritical boiler technology.”

The power plant will include a direct, once-through cooling system, which will use water abstracted from the Nile River. The abstracted water will also be used as process water make-up in the boiler system, following pre-treatment.

The project also comprises an open boiler building, a common control room, and other associated structures and facilities.

Emergency generators will be installed for the safe shut down of the plant in the event of a power supply failure. The generators will operate on solar oil (light fuel oil), which can also be used to operate the auxiliary boiler during start-up, if required.

Power transmission from South Helwan thermal power plant

Power generated by the South Helwan power plant will be transmitted to the Egyptian Unified Power System (UPS) through interconnected overhead transmission lines (OTL).

The project will require the construction of a 200km-long, 500kV double-circuit OTL to transmit power from the plant through the proposed Minya East 500 route, and a 150km-long, 500kV double circuit OTL to transmit power through the Bader 500 route.

Natural gas supply for South Helwan supercritical plant

A new gas pipeline will be constructed with an estimated investment of $235.5m to extend the existing gas network joint at Dahshour to the power plant. It will run along the western bank of the Nile to reach the South Helwan site.

Financing

The World Bank’s lending arm International Bank for Reconstruction and Development (IBRD) is providing a loan of $585m for the project.

The project has also received funding from a number of financial institutions, including Arab Fund for Economic and Social Development ($193.5m), Islamic Development Bank ($450m), Kuwait Fund for Arab Economic Development ($213.8m), and OPEC Fund for International Development ($40m).

Contractors involved

Techint Engineering and Construction was awarded the engineering, procurement and construction contract for the mechanical balance-of-plant of the South Helwan power project.

Power Generation Engineering and Services (PGESCO) was contracted for the detailed design of the plant systems in October 2011.

PGESCO sub-contracted Hassan Allam for conducting the civil works and SIAC Industrial Construction & Engineering for site services, while Tubi Acciaio Lombarda was sub-contracted by Techint for the supply of steel pipes, fittings and flanges.

UEEPC awarded a joint contract to Mitsubishi Heavy Industries and Toyota Tsusho Corporation for the supply of steam turbines, generators, condensers, and other auxiliary equipment.

EEHC contracted AC Boilers for the supply of three supercritical gas/oil-fired boilers. AC Boilers sub-contracted Pompe Garbarino (La Garbarino) for the supply of chemical pumps, vertical in-line pumps, and lateral channels.

KSB Group was awarded the contract for the supply of 27 power station pumps in November 2015, while Cimtas Pipe is the supplier of critical piping and valves package, as well as 1,670t of pipe spools.

Arcons was engaged for the erection of steel structures and cladding works, while Acrow Integrated Construction Services was contracted for the civil engineering works.
