Power Plant Equipment in Iraq: Selection & Procurement Guide

Iraq's power sector is the country's single largest infrastructure investment programme. Federal targets call for adding over 10,000 MW of capacity by 2030, alongside continuous spare-parts renewal across an installed base that mixes gas turbines, steam turbines and combined-cycle units commissioned over the past 20 years. This guide covers equipment selection and procurement for new builds, major-equipment replacement, and high-volume spares programmes in the Iraqi power generation context.

Generation technology choices

Three dominant configurations in Iraq:

• Simple-cycle gas turbines for peaking and load-following. Fast to deploy, lower capital, lower efficiency.
• Combined-cycle gas turbines for baseload. Higher efficiency, longer build time, requires reliable fuel-gas supply.
• Steam turbines (heavy fuel oil or natural gas fired) for legacy baseload assets and some new builds.

Major equipment categories

Gas turbines and ancillaries

Original gas turbines are typically sourced from the major OEMs at the time of plant build. Replacement parts, however, are subject to a more open spares market — combustion components, IGV actuators, fuel-system parts, governor electronics, generator AVRs and exciter assemblies all flow through a robust independent-supplier channel.

Steam turbines

Iraq operates a meaningful fleet of steam turbines, particularly at northern and central thermal power plants. Spares demand is concentrated in seal-gas systems, lube-oil systems, governor electronics, and the casings/rotor consumables that accompany scheduled outages.

Generators

Generator service typically focuses on the AVR, exciter, brushless modules, and the supporting protection electronics. Rotor and stator rewinds are a separate specialist service market — our team coordinates with certified rewinder partners for these scopes.

Transformers and switchgear

Step-up transformers (generator-to-transmission), auxiliary transformers, and the MV/HV switchgear at the plant fence are the major electrical balance items. Iraqi transmission operates at 132, 220 and 400 kV; plant-side voltages are typically 11 or 33 kV.

Auxiliary systems

Boiler feed pumps, condensate pumps, cooling-water pumps, fans, and the supporting motors and drives. Lube oil systems, instrument-air systems, and water-treatment plant equipment all consume spares continuously.

Selecting equipment for the Iraqi environment

Plant-specific selection should account for:

• Ambient temperature — derating curves for gas turbines, motor windings, and electronics are not optional. Specifying for 50 °C ambient (45 °C in northern plants) is mandatory.
• Air quality — sand, dust, and humidity at southern plants require filtration upgrades on gas turbines and IP55+ enclosures on outdoor electrical equipment.
• Fuel quality — natural gas supply can be intermittent at some plants. Heavy fuel oil firing remains common and the equipment must be specified for it.
• Water availability — cooling-water source quality varies. Plants near Basra often run on brackish water; air-cooled condensers are increasingly common.

Procurement workflow on a new build

1. 01Conceptual selection during FEED — gas turbine class, cycle configuration, plant capacity.
2. 02Detailed engineering with specific BoM. Major-equipment specifications are typically called out by manufacturer and part number.
3. 03Vendor pre-qualification for each major package, where buyer is a federal generation company.
4. 04Factory acceptance testing in the manufacturer's facility, with buyer or its consultant as witness.
5. 05Sea freight to Umm Qasr for heavy items; air freight for accelerated electronics.
6. 06Site delivery, installation, pre-commissioning.
7. 07Performance acceptance testing at site under load.

Spare parts programmes

For operating plants, spare-parts programmes typically follow three tracks:

• Major outage spares — held centrally, consumed during scheduled major maintenance.
• Operational spares — held at site, consumed against plant operational events.
• Critical / single-point-of-failure spares — held against component classes that, if failed, would force an extended outage.

A managed spare-parts programme typically involves an annual critical-spares review, vendor-managed inventory at site, and clear replenishment triggers.

Why The Power Contractor

We are independent. We supply genuine new OEM equipment from authorised channels, ship with full documentation, and do not deal in refurbished or counterfeit parts. Our regional Iraq team is reachable on iraq@thepowercontractor.com and on WhatsApp; standard response on a quote is within 24 hours.
