Rumah and Nairiyah tariffs set precedent

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 selects contractors for well tie-ins project27 October 2026

Abu Dhabi National Oil Company’s onshore operating arm (Adnoc Onshore) has selected contractors for a major project to tie in wells across the Bab and North East Bab oil field developments in Abu Dhabi.
Located 84 kilometres southwest of Abu Dhabi city, the Bab field has been in production since 1960 and is the emirate’s first oil-producing asset. The North East Bab cluster comprises the Al-Nouf, Rumaitha and Shanayel fields.
The Bab and North East Bab One Tie-In project is central to Adnoc Onshore’s contribution to Adnoc Group’s target of expanding crude oil production capacity to 5 million barrels a day (b/d) by 2027, an initiative known as the Accelerated Integrated Programme 5. The state energy company’s total production capacity currently stands at approximately 4.85 million b/d.
According to industry sources, Adnoc Onshore has selected local contractor Robt Stone Middle East and China’s Jereh Group to carry out engineering, procurement and construction (EPC) works on the project. While both firms have been notified of their selection, a formal project kick-off meeting has yet to take place.
Adnoc Onshore is understood to have started the tendering process for the Bab and North East Bab One Tie-In project last year, with contractors submitting technical and commercial bids earlier this year.
Following the evaluation of bids, Adnoc Onshore sought best commercial offers from the bidders, which contractors submitted in May, MEED previously reported.
The project budget is estimated at $1.2bn.
Bidders for the contract are understood to have included:
- Galfar Emirates (UAE branch of Oman’s Galfar Engineering & Construction)
- Jereh (China)
- Kalpataru Projects International (India)
- Matrix Construction (UAE)
- Robt Stone Middle East (UAE)
- Target Engineering Construction Company (UAE)
The project scope covers residual engineering, procurement of materials not supplied as free-issue items, site surveys, construction, installation, inspection, testing, and pre-commissioning and commissioning support. The works will deliver new wellsite facilities, including a new mini-pad, well bays and clusters across the Bab and North East Bab developments.
Adnoc Onshore is Adnoc Group’s largest production subsidiary, accounting for roughly 2 million b/d of crude and about 7 billion cubic feet a day of associated gas from four primary onshore asset clusters: Bab, Bu Hasa, North East Bab and South East.

Ashghal tenders Al-Udeid air base access road works27 October 2026

Qatar’s Public Works Authority (Ashghal) has invited contractors to bid on a contract to build roads and related infrastructure around Al-Udeid Air Base.
The project is located in Zone 95 of Al-Wakra Municipality, adjacent to Al-Majd Road.
The tender was issued on 22 October, with a submission deadline of 22 November.
The scope includes the construction of a dual-lane carriageway to improve access to the air base, together with three roundabouts. The alignment will connect to Al-Majd Road to the east and tie into Street 203 in Zone 95 to the west. The contractor will also resurface and maintain connections to the existing road network.
Associated works include street lighting, intelligent transport systems, directional signage and a surface-water drainage collection system.
The contractor will provide crossing ducts, protect and relocate conflicting existing utilities, and complete detailed utility designs as required by relevant stakeholders through the Qatar Design Review System.
The project also includes the design and construction of two electrical substations. The contractor must secure the necessary stakeholder and authority approvals before starting these works.
The scheme will be delivered on a remeasurable, build-only basis using designs approved by others. It will also include designated contractor-designed elements and design-and-build packages for the substations.
Bidders must submit two commercial pricing options: a base offer subject to material price-fluctuation provisions, and an alternative authority option without such provisions.
The contract has a 550-day completion period from the commencement date, including mobilisation, followed by a 400-day maintenance period after the completion certificate is issued.
Participation is restricted to local and international contractors registered under the Ministry of Finance classification system in Grade A or Grade B for road specialisation.
Unclassified foreign firms may submit equivalent certified documentation from their country of origin, attested by Qatari diplomatic missions. They must obtain Ministry of Finance registration before contract award.
For joint-venture bids, the lead partner must hold the required classification grade.

Saudi Arabia gauges interest for Al-Ula wastewater expansion27 October 2026

Saudi Arabia’s Royal Commission for Al-Ula (RCU) is conducting market sounding for the first phase of the Mughayra wastewater treatment plant (WWTP) expansion before formally starting its tendering process, according to industry sources.
The project is valued at SR400m ($107m) and is intended to increase the Mughayra plant’s wastewater treatment capacity to 62,000 cubic metres a day.
RCU is gauging interest from potential contractors and has not yet issued a prequalification questionnaire, a source said.
The scheme forms part of Saudi Arabia’s broader investment drive to develop its cultural and tourism offering across Al-Ula.
The commission launched its Journey Through Time Masterplan in April 2021, with implementation scheduled in three phases through 2035. The masterplan covers infrastructure development, water management and irrigation, alongside the regeneration of a 9-kilometre cultural oasis.
French engineering firm Artelia previously noted in its 2025 annual corporate report that it is involved in the design phase of the Mughayra WWTP.
RCU is also developing strategic potable-water storage infrastructure in Al-Ula, including a design-and-build project covering a 50,000-cubic-metre reservoir at Hub 06 and a 15,000-cubic-metre reservoir at Hub 08.
Local contractor Bin Omairah previously confirmed that it is serving as the engineering, procurement and construction contractor for the storage facilities.

Qatari firm wins $147m Syria road deal27 October 2026
Qatari contractor Al-Mohannadi for Roads, Trading & Contracting has signed a $147m contract with Syria’s General Directorate of Roads to rehabilitate and expand a 215-kilometre (km) highway corridor connecting to the Iraqi border.
The project covers the rehabilitation and dualisation of a 170km section linking the Al-Busairi junction to the Al-Tanf border crossing, alongside the construction of a 45km link between the Al-Sabaa Biyar junction and Al-Busairi. Work is scheduled for completion within 900 days.
The agreement was signed in Damascus by Moaz Najjar, director-general of the General Directorate of Roads, and Abdullah Adnan Al-Zattam, chief executive of Al-Mohannadi, in the presence of Syrian Transport Minister Yarob Badr and Finance Minister Mohammad Yusr Barnieh.
The upgrade is intended to restore and expand one of Syria’s primary overland arteries to Iraq, which has suffered significant deterioration and capacity bottlenecks following years of conflict. The Al-Tanf corridor represents the most direct overland link between Damascus, central Syrian industrial centres and Baghdad.
The project is designed to accommodate heavier commercial freight vehicles and reduce transit times between the two countries.
The investment also forms part of broader efforts to re-establish Syria’s role as a regional transit corridor connecting Mediterranean ports with landlocked trade routes into Iraq and the wider region.

Adnoc showcases $16.3bn local manufacturing potential27 October 2026
Abu Dhabi National Oil Company (Adnoc Group) has identified more than AED60bn ($16.3bn) in local manufacturing opportunities through 2030.
The Abu Dhabi energy company also announced changes to its procurement, supplier registration and In-Country Value (ICV) localisation frameworks.
The measures were announced at the second Make it with Adnoc Forum, held in Abu Dhabi on October 25. They are intended to give manufacturers, suppliers and investors greater visibility of future demand and a faster, clearer route to compete for Adnoc contracts, the company said.
The more than 200 manufacturing opportunities cover products required for Adnoc’s projects and operations, including:
- Rotating equipment and power
- Electrical, control and automation systems
- Drilling and completion equipment
- Chemicals and catalysts
- Piping, fabrication and heavy equipment
- Spare parts and advanced manufacturing
Many of the identified products are currently imported, Adnoc said. “Manufacturing them in the UAE shortens lead times, reduces exposure to global supply disruptions and strengthens the resilience of Adnoc’s operations,” it said in its statement.
Adnoc, the UAE Ministry of Industry & Advanced Technology and the Abu Dhabi Investment Office (Adio) will work together to connect manufacturers with these opportunities. The collaboration will combine visibility of Adnoc’s demand, access to the national industrial database and financing through the National Industrial Resilience Fund, the company said.
Adnoc also signed two memorandums of understanding on the sidelines of the forum with Adio and Kezad Group.
ICV scheme expansion
Adnoc announced the expansion of its Local+ programme, part of its ICV framework, to more than 100 UAE manufacturers, compared with 70 at its launch in May. The programme gives UAE-made products priority in Adnoc projects by requiring engineering, procurement and construction (EPC) contractors bidding for new tenders to source relevant products from manufacturers approved under the programme.
Separately, Adnoc announced a redesign of its supplier registration and prequalification process. The company is targeting a reduction of up to 80% in the time required for suppliers to complete the process and become eligible to compete for Adnoc opportunities.
The new model halves the number of required documents and removes prequalification requirements for 60% of service categories.
A single window brings together registration, qualification and compliance, with requirements tailored to the nature of the work and its level of risk. Artificial intelligence will support document verification and the reuse of existing data, reducing repetitive submissions and administrative processing.

“Adnoc’s enhanced ICV model will more closely connect procurement decisions with commercial value and suppliers’ contribution to the UAE economy. Under the new model, commercial and ICV offers will be integrated into a single evaluation model,” the company said.
“The previous bid-matching approach will be retired, encouraging suppliers to submit their most competitive commercial and ICV offers from the outset. Requirements will be proportionate to contract size and scope.
“The model also enhances the administration of ICV-related retention payments. Where retention applies, automated calculation and release processes through the Adnoc Supplier Hub will improve transparency, reduce manual follow-up and support suppliers’ cash flow as obligations are met.”
Alongside the ICV and registration enhancements, Adnoc outlined a new commercial approach built around four strategic shifts: agile, competitive, strategic and forward-looking.
“The approach will advance simpler procurement and faster decision-making, contracting models aligned with project and market dynamics, targeted commercial negotiations and earlier visibility of Adnoc’s future demand.”
Since its launch in 2018, Adnoc’s ICV programme has directed more than AED307bn ($83.6bn) into the UAE economy, the company said. By the end of 2025, it had also supported the localisation of more than 130 products, the development of 95 UAE factories, and employment opportunities for more than 27,500 Emiratis at participating private sector companies.
