The levelised costs of electricity (LCOEs) for the four combined-cycle gas turbine independent power projects (IPPs) recently awarded in Saudi Arabia are expected to set a precedent for tariffs in upcoming thermal IPPs procured in the GCC region.

Two separate developer consortiums bid for and won the contracts to develop the Rumah 1 and 2 and Nairiyah 1 and 2 IPPs, which are located in Riyadh and the Eastern Province, respectively.

A consortium comprising Saudi Electricity Company (SEC), Riyadh-based utility developer Acwa Power and South Korea’s Korea Electric Power Corporation (Kepco) won the contract to develop the Rumah 1 and Nairiyah 1 IPPs, each with a capacity of 1,800MW.

The team offered an LCOE of $cents 4.5859 a kilowatt-hour ($c/kWh) for Rumah 1, and $c4.6114/kWh for Nairiyah 1.

A consortium comprising the UAE-based Abu Dhabi National Energy Company (Taqa), Japan’s Jera Company and the local Albawani Company won the contract to develop and operate the Rumah 2 and Nairyiah 2 IPPs. 

The Taqa-Jera-Albawani consortium offered an LCOE of $c4.5613/kWh for Rumah 2, and $c4.4960/kWh for Nairiyah 2.

LCOEs represent an all-in tariff including capital and operating expenditures during the power-purchase agreement (PPA) period. In this case, the principal buyer, Saudi Power Procurement Company, agreed to buy the electricity from the project companies for 25 years.

The last comparable IPP procured by SEC in Saudi Arabia was Rabigh 2, for which Acwa Power proposed a tariff of $c1.9/kWh in 2012-13. Rabigh 2 is older than the Fadhili IPP, which was awarded in 2016, but the latter is a cogeneration plant, which was won by France's Engie.

Engineering, procurement and construction (EPC) contractors and original equipment manufacturers say that capital expenditure (capex) for building thermal plants has significantly increased compared to before the Covid-19 pandemic.

Estimates indicate that EPC costs have increased from about $500/kWh to $700-$800/kWh since around 2020.

Despite this, the latest thermal IPP tariffs in Saudi Arabia do not appear significantly higher compared to the tariff for the Fujairah F3 IPP in the UAE, which was procured in 2020.

Several factors underpin tariff trends, according to experts. LCOEs cover fuel capex recovery and operating expenses, where fuel can represent 70%-80%, depending on the prevailing fuel price during the proposals stage.

It should also be noted that the fuel prices and project ownership structures vary depending on jurisdiction, which directly affects the LCOE.

Scale, with the four Saudi plants being awarded together, is also an important factor, as is the technology, because more energy-efficient gas turbines could have contributed to keeping the Saudi tariffs lower than initially expected.

A transaction adviser also notes that the 2024 cost of debt outlook is lower, so swap rates are lower.

Crucially, MEED understands that the tariffs submitted for Rumah and Nairiyah do not yet include potential exit costs, assuming a carbon capture, utilisation and storage (CCUS) solution is not reached while the PPAs are in force.

According to an industry source, CCUS discussions for the Rumah and Nairyah IPPs are set to begin in the 2030s, and the tariffs agreed today will be adjusted based on the outcome of those discussions. 

All this suggests that interesting comparisons will be soon drawn between the Rumah and Nairiyah tariffs in Saudi Arabia and the tariffs that bidders plan to propose for the Taweelah C and Madinat Zayed schemes in Abu Dhabi.

  • Adnoc Onshore seeks bids for Bu Hasa field EOR project

    16 October 2026

     

    Register for MEED’s 14-day trial access 

    The onshore oil and gas business of Abu Dhabi National Oil Company (Adnoc Onshore) has sought bids from contractors for a key project to increase the oil production capacity of the Bu Hasa oil field, primarily through enhanced oil recovery (EOR) techniques.

    The main objective of the Bu Hasa-Shuaiba EOR Unit 1 (Phase 1) project is to achieve a targeted 70% increase in oil production, extend the Bu Hasa field development’s production plateau and maximise the field’s potential in an economical manner.

    The project aims to confirm and validate the optimum EOR technology for the top-ranked reservoirs/units; assess incremental recovery on top of the improved oil recovery (IOR) wedge; extend the field plateau for as long as is economically feasible; and achieve an ultimate recovery factor of 70% from the Shuaiba reservoir. It will evaluate and execute the recommended EOR option through pattern phasing for any technology proven by Adnoc.

    Adnoc Onshore is understood to have issued the tender for the project on 20 September, with an initial technical bid submission deadline of 8 October, according to sources. The client later extended the technical bid submission deadline to 17 October, sources told MEED.

    The chosen contractor will execute the project under a hybrid contracting strategy comprising:

    • A lump sum (turnkey) EPC scope covering the complete pipeline system from East Hub to the separation plant
    • A call-out-based scope for execution of all WAG injector and WSW tie-in works

    Unless otherwise specified, all activities defined under the contractor’s scope will be deemed included within the lump-sum contract price. This will cover engineering, procurement, construction, testing, pre-commissioning and support to commissioning for a complete and operable system.

    At the Bu Hasa field development, three remote degassing stations (RDS-1/2/3) and two satellite stations, Bida Al-Qemzan and Huwaila, are currently in operation. Production from oil wells completed in Shuaiba, Thamama B, Thamama F, Bida Al-Qemzan and Huwaila is routed via individual flowlines to the three remote degassing stations and the Bida Al-Qemzan and Huwaila stations across different parts of the field.

    Combined production from the wells at each of these stations is routed to the central degassing stations (CDS) via transfer lines ranging from 16 inches to 24 inches in diameter. In addition, some wells in the central part of the field are connected directly to the CDS.

    Previous studies have identified carbon dioxide (CO2) flooding as a promising tertiary recovery mechanism in the Shuaiba reservoir, delivering incremental recovery on top of the IOR wedge (P5 project), extending the field plateau as long as economically feasible, and achieving an ultimate recovery factor of 70% from the Bu Hasa Shuaiba units.

    Located 200 kilometres south of Abu Dhabi city, Bu Hasa is Adnoc Onshore’s westernmost producing field. It is one of Abu Dhabi's biggest onshore assets, with crude oil production capacity of 650,000 b/d. It is also one of the Adnoc Group’s oldest oil fields, having been discovered in 1962 and in production since May 1965.

    As part of the ongoing Bu Hasa Integrated Field Development Project (BUIFDP), 13 new well pads and two pad hubs have been added to the field. Oil, gas and water produced at these sites will be collected at a central gathering facility, then sent through production headers and transfer lines to the CDS for processing.

    Adnoc Onshore is the Adnoc Group’s largest oil-producing subsidiary, accounting for 2 million b/d of oil and about 7 billion cubic feet a day of associated gas production from four main onshore field developments in Abu Dhabi: Bab, Bu Hasa, North East Bab and South East.

  • OTTCO issues tender for Oman oil storage park expansion

    16 October 2026

     

    Register for MEED’s 14-day trial access 

    Oman Tank Terminal Company (OTTCO) has issued the main tender for a major project related to the expansion of the Ras Markaz crude oil storage complex at Duqm, on the sultanate’s Arabian Sea coast.

    The project, titled Trade Bridge, involves the engineering, procurement and construction (EPC) of eight large storage tanks, each with a capacity of 650,000 barrels. This will increase the Ras Markaz terminal’s total storage capacity by 5.2 million barrels.

    The project represents the next expansion phase (phase 1.4) of the Ras Markaz oil storage terminal within the Special Economic Zone at Duqm (Sezad).

    State-owned OTTCO issued the prequalification notice for the project on 28 July, with contractors submitting initial responses by 4 August and final responses by 19 August, MEED previously reported.

    According to sources, OTTCO issued the main tender for EPC works on Project Trade Bridge in the weeks following completion of the prequalification exercise.

    The following contractors, among others, are understood to have been prequalified by OTTCO to bid for Project Trade Bridge:

    • China Petroleum Pipeline Engineering Company (China)
    • China Tianchen Engineering Corporation (China)
    • Daqing Oilfield Construction Group Company (China)
    • Enppi Muscat (local branch of Egypt-based Enppi)
    • Gulf Petrochemical Services & Trading (Oman)
    • Hualu Engineering & Technology Company (China)
    • Rotary Engineering (Singapore)
    • Sinopec Ningbo Engineering Company (China)

    OTTCO commissioned the first phase of the Ras Markaz crude oil storage park, covering 10 square kilometres and with a capacity of 26.7 million barrels, in December 2022.

    The storage facility has two parts. The first is a marine services area, which includes a floating station for crude imports and exports. This zone is about 7 kilometres offshore and is connected via two 42-inch pipelines and associated facilities.

    In water depths of up to 42 metres, the floating station can accommodate very large crude carriers. It is linked to four main pumps that transfer crude oil to the storage area, which is located more than 120 metres above sea level. OTTCO could add pumps at a later stage to keep pace with future demand for oil storage.

    The second part of the storage facility features oil pumping systems, water treatment facilities, reservoirs, power station networks and other associated systems.

    Region’s largest oil storage park

    OTTCO will build the Ras Markaz oil storage facility in five phases over several years across an area of about 40 square kilometres, for which it signed a land agreement with Sezad in July 2017.

    It will be able to hold 200 million barrels of crude a year. Total investment in the scheme is understood to be $5.2bn.

    The storage terminal in the first phase of the Ras Markaz facility is connected to the estimated $7bn Duqm refinery and other oil-derivatives production plants at Sezad via a pipeline that will supply crude feedstock to the refinery when required.
