Samawa 750 MW Combined Cycle Power Plant

ENKA and its partner General Electric (GE) are to design and build the Samawa Combined Cycle Power Plants, which will add 750 MW to the Iraqi grid. The Samawa project is located near Samawa City, 293 km northwest of Basra.

The gas turbines for the projects have been purchased by the Ministry of Electricity of Iraq as part of the Mega-Deal between the Government of Iraq and GE. They are to be handed over to GE-ENKA for installation and commissioning. These units are the last gas turbines to be installed under the Mega-Deal. All other materials and equipment are to be purchased and shipped to Iraq by GE-ENKA.

The project consists of a single power block producing 750 MW of power at transmission levels of 132 kV and 400 kV. The configuration of the combined cycle will be 4x4x1. Four GE 9E series combustion turbine generators capable of operating on three types of fuel are to be installed at the plant. Each Gas Turbine will be coupled with a Heat Recovery Steam Generator to convert the exhaust energy of Gas Turbine to steam. The steam then will be diverted to a 250 MW capacity Steam Turbine Generator to produce additional power. The cooling of the plant will be performed by Air Cooled Condenser. The main fuel to be used at the Samawa plant is heavy fuel oil. The back-up fuels for the plant are light distillate oil and natural gas. The equipment is designed to operate for 24 hours a day, 7 days a week, with a useful life span of 25 years.

The plant will be the first combined cycle facilities to be owned and operated by the Ministry of Electricity. The thermal efficiency is to be in excess of 50%, which will help Iraq to save a total of 14 billion cubic meters of natural gas and 32 million tons of carbon dioxide over the 25-year operating period.

The project financing is being arranged by the Overseas Private Investment Corporation (OPIC) and the Export Credits Guarantee Department of the Government of the United Kingdom (UKEF).

Among the partners, ENKA is responsible for engineering, procurement of balance-of-plant, construction, erection, commissioning and start-up, while GE is to provide the power island equipment (i.e. steam turbine generator, heat recovery steam generator, air cooled condenser and main transformers) and the distributed control system and switchyard. The plant’s performance tests are also under the responsibility of GE.

The contract was signed in January 2017 and the project is scheduled to be completed within 34 months of commencement.

In order overcome financing and budget challenges, Employer requested to execute the project in two phases: Phase 1 and Phase 2 and the Contract Amendment was signed on 28 November 2018 accordingly. The project scope of work is diveded into two (2) phases.

Phase 1 scope is broadly reflecting the completion of the simple cycle plant, including the 132 kV AIS and 400kV GIS and common balance of plant in the size and capacity to accommodate the combined cycle operation.

Phase 2 scope is broadly reflecting the completion of the combined cycle plant (adding on equipment to make the plant a combined cycle plant)

Although the Commencement Date for the projects was 20.01.2018, in July 2018 project was suspended.
