Saudi Arabia to expand grid by 60% by 2030
21 March 2025
State utility Saudi Electricity Company (SEC) aims to expand its power transmission network to approximately 160,000 kilometres (km) by 2030, up 60% over its existing network of about 99,800km.
An increased subscriber base and higher electricity consumption, as well as the integration of renewables, underpin plans to expand the SEC network over the next five years.
"By 2030, SEC aims to expand its transmission network to encompass approximately 160,000km of transmission lines, [and] install nine new high-voltage, direct current lines between regions and neighbouring countries," SEC said in its 2024 earnings report.
"These targets are underscoring our commitment to building a robust and future-ready grid infrastructure."
MEED understands that SEC energised 26 new transmission substations, increasing the kingdom's transmission network to 1,260, a 2.1% increase over 2023.
These new substations increased the cumulative substation capacity to 497,902 megavolt-amperes, a 2% growth over the previous year.
Of the total, SEC installed and energised 10 substations and added 148.5km of transmission lines, integrating 6.6GW of renewables in 2024.
An additional 24 substations and 4,327km of transmission lines are under construction to integrate about 34.4GW of renewable energy capacity into the grid by 2027.
Generation
SEC said generation capacity connected to the grid reached 92.15GW in 2024, up 6.9% over 2023, when installed capacity stood at 86.23GW.
The firm said its directly owned capacity of the total now stands at 56.4GW, representing 61% of the kingdom's total capacity.
Electricity production at SEC's plants surged 7.5% to 236.4 terawatt-hours in 2024.
The firm said that 1,580MW of generation capacity was added or restored to SEC's power plant fleet in 2024, while the liquid-to-gas conversion of the Riyadh power plant 10 (PP10) and phase one is expected to be completed this year.
SEC is working with local contracting company Alfanar, in addition to US-based original equipment manufacturer GE Vernova, to convert the plant's fuel feedstock to natural gas, a lower carbon intensity fuel compared to the crude oil and distillate that currently power the plant.
According to the Energy Institute, Saudi Arabia's total electricity generation in 2023 reached 422.9 terawatt-hours (TWh). Oil accounted for 152.1TWh, or about 36% of the total, while natural gas accounted for 265TWh, or 63%, and renewables made up 5.8TWh or 1%.
"Eight projects with a total capacity of 22.3GW are under transition by 2030," SEC said in its report.
It added: "SEC is currently developing 11 generation projects with an aggregate 23.4GW of capacity. These will be across directly owned capacity projects (10.476 GW), expansion and partnerships (5.324GW) and joint venture projects (7.610GW)."
Battery storage
SEC has been procuring battery energy storage system (bess) plants, with the aim of boosting the reliability and flexibility of the kingdom's electricity grid.
The first 500MW bess project in Bisha has been completed, while work is under way for 22 gigawatt-hours of bess capacity across five projects that are under development.
SEC is also prequalified to bid for the first round of independent bess projects in the kingdom, which is being produced by Saudi Power Procurement Company.

Saur and Nesma sign water infrastructure deal26 August 2026
French firm Saur and local contractor Nesma & Partners have signed a deal to jointly "pursue the design and construction" of two recycled water plants in Riyadh.
The memorandum of understanding (MoU) was signed during the French-Saudi Investment Roundtable Meeting in Paris on 24 August.
It builds on an earlier agreement by the companies last September focusing on developing desalination and sewage treatment plants aceross the kingdom including project development, engineering, procurement, construction (EPC) and long-term operations and maintenance (O&M).
At the time, the companies agreed to "target industrial water treatment through concession and operations contracts," extending the agreement beyond municipal water infrastructure.
The latest agreement appears to mark a move from the broader partnership towards specific project opportunies in the Riyadh market. Details of the projects were not disclosed.
In May, MEED exclusively reported that a consortium including Saur, Nesma and another local firm Al-Bawani was preparing to bid for the Riyadh East Independent Sewage Treatment Plant (ISTP) project, of which, the submission deadline was recently extended to 29 September.
There are almost $2.5bn worth of water treatment projects at the pre-execution stage in Saudi Arabia, according to regional tracker MEED Projects.
The French-Saudi Investment roundtable meeting was organised as part of Saudi Crown Prince and Prime Minister Mohammed Bin Salman’s state visit to France.
Saudi Aramco also announced agreements and a memorandum of understanding (MoU) with French companies, worth a potential combined value of more than $3.7bn.
Among the other agreements signed during the conference was a cooperation agreement between Saudi Energy and French public investment bank Bpifrance, valued at up to $3bn, to support financing for projects to develop and expand Saudi Arabia’s power grid.

Technip Energies secures role in Umm Shaif Gas Cap project26 August 2026
France-based Technip Energies has secured a contract to provide detailed engineering services on a key offshore package part of the Umm Shaif integrated gas cap and surface pressure boosting project of Adnoc Offshore.
The detailed engineering services deal was awarded as a sub-contract to Technip Energies by India’s Larsen & Toubro Energy Hydrocarbon (L&TEH), in its capacity as the main contractor on the package 1 of the Umm Shaif gas cap project.
MEED previously reported about the offshore business of Abu Dhabi National Oil Company (Adnoc Offshore) awarding the main EPC contract for package 1 to a consortium of L&TEH and Saudi Arabia/UAE-based Lamprell.
Both L&TEH and Lamprell have confirmed their respective contract awards.
Under the detailed engineering contract, Technip Energies, in its statement on 26 August, said it “will draw on its strong local engineering capabilities and extensive experience with complex, large-scale offshore projects in the Middle East.”
In July, Adnoc and its foreign partners announced a $6.2bn final investment decision (FID) for their project to produce up to 600 million cubic feet a day (cf/d) of natural gas by developing the Umm Shaif Gas Cap in Abu Dhabi.
The Umm Shaif Gas Cap reserve is located within the offshore Umm Shaif and Nasr hydrocarbons concession, which is operated by Adnoc as the majority stakeholder. The other stakeholders in the concession are Italy’s Eni, France’s TotalEnergies and China National Petroleum Corporation (CNPC).
Adnoc said the FID includes three EPC packages totalling $5.1bn for large-scale offshore infrastructure, awarded to consortiums comprising major UAE and international contractors. The company did not disclose the contractors or the scope of work.
MEED reported in May that the following contractors had emerged as frontrunners for the two offshore packages and one onshore package of the Umm Shaif gas cap and surface pressure boosting project:
- First offshore package – fabrication of a 30,000-tonne gas compression system: Larsen & Toubro Energy Hydrocarbon (India) / Lamprell (Saudi Arabia/UAE)
- Second offshore package – fabrication of another 30,000-tonne gas compression system: McDermott (US)
- Onshore package – EPC of gas inlet and processing systems on Das Island: China Petroleum Engineering & Construction Company (CPECC)
McDermott recently confirmed its contract award for package 2, describing the order as “mega”, a term the company uses for jobs valued above $1bn.
In its 21 July statement, Adnoc added that, as part of the FID, it has also awarded a $365m contract to its subsidiary Adnoc Drilling for a 14-well drilling and integrated drilling services scope, to be delivered over 18 months using three existing rigs.
“The FID for Umm Shaif Gas Cap is the latest milestone in the company’s gas growth strategy and will unlock more than 600 million standard cubic feet per day of natural gas and associated gas liquids, equivalent to almost 10% of the UAE’s current daily gas consumption. The investment will reinforce the UAE’s energy security and its role as a reliable global energy supplier,” Adnoc said.
Production from the development is expected by 2030, the Abu Dhabi energy giant said.
“The UAE holds the seventh-largest gas reserves in the world. As global demand for reliable, lower-carbon energy continues to grow, Adnoc is unlocking more of the nation’s gas resources and expanding its liquefied natural gas (LNG) portfolio to meet the needs of its domestic and international customers and power industrial and artificial intelligence (AI) infrastructure growth,” it added.
Umm Shaif Gas Cap project
Adnoc Offshore, the offshore oil and gas business of Adnoc Group, is the operator of the Umm Shaif gas cap and surface pressure boosting project, MEED has reported.
The primary objective is to increase gas production by 550 million cubic feet a day (cf/d) and raise associated condensate output by 50,000 barrels a day (b/d).
Adnoc Offshore intends to feed about 520 million cf/d of the additional produced gas into Adnoc Group’s sales gas grid.
Adnoc Offshore is understood to have issued the main EPC tender for the Umm Shaif gas cap and surface pressure boosting project in the first quarter of 2025.
Contractors submitted technical bids for the three EPC packages by the 30 October deadline last year, while commercial bids were submitted by the 2 February deadline.
The following contractors are among those understood to be bidding for the three EPC packages, according to sources:
Offshore package 1:
- Saipem (Italy) / Seatrium (Singapore)
- Larsen & Toubro Energy Hydrocarbon (India) / Lamprell (Saudi Arabia/UAE)
- NMDC Energy (UAE) / Hyundai Heavy Industries (South Korea)
Offshore package 2:
- China Offshore Oil Engineering Company (COOEC)
- McDermott (US)
- Larsen & Toubro Energy Hydrocarbon (India) / Lamprell (Saudi Arabia/UAE)
- NMDC Energy (UAE) / Hyundai Heavy Industries (South Korea)
Onshore package:
- Archirodon (Greece)
- China Petroleum Engineering & Construction Company (CPECC)
- Engineering for the Petroleum & Process Industries (Enppi; Egypt)
- Galfar Emirates (UAE branch of Oman’s Galfar Engineering & Construction)
- Target Engineering Construction Company (UAE)
Australian firm Worley has performed front-end engineering and design (feed) work on the project.
Umm Shaif gas production
Adnoc Offshore operates the Umm Shaif hydrocarbons development, which is located 150 kilometres (km) northwest of the city of Abu Dhabi. The field is located in Abu Dhabi’s offshore Umm Shaif and Nasr hydrocarbons concession, previously operated by former Adnoc Group companies Adma-Opco and Zadco.
In March and April 2018, Abu Dhabi’s Supreme Council for Financial and Economic Affairs (SCFEA) awarded a 10% stake in the Umm Shaif and Nasr offshore block to Eni, 20% to TotalEnergies and 10% to CNPC. Adnoc Group retained the majority 60% interest. The operators produce a total of about 460,000 b/d of oil from the Umm Shaif and Nasr block.
Gas is produced from the Umm Shaif Khuff and Uweinat reservoirs, as well as from the Arab C and Arab D Early Production Scheme 2. The Umm Shaif Khuff reservoir is a formation that consists of dry gas volumetric reservoirs located in the Umm Shaif field.
Khuff reservoirs have been in production in Abu Dhabi since August 1989. Umm Shaif Khuff gas is currently produced from 28 active wells within the Umm Shaif field. A majority of these wells supply gas to Adnoc Group subsidiaries Adnoc LNG and Adnoc Gas Processing, with the rest supporting oil reservoirs at the Umm Shaif field through gas injection.
The Umm Shaif Super Complex (USSC) processes and transports oil, condensates and natural gas in separate pipelines to Das Island for further processing and export. The condensates collected from the USSC are transported to Das Island through an 18-inch pipeline stretching 34.4km, or are spiked into the 36-inch Adnoc main oil line.
The gas collected from the USSC is transported to Das Island through two 46-inch pipelines, which also run 34.4km.
Pressure at the Umm Shaif Khuff gas reservoirs will start to decline by the end of 2028. The flowing wellhead pressures at some of the Khuff gas wellhead towers are likely to reduce, so boosting well deliverability and increasing the flowrates is necessary.
Therefore, new Khuff surface pressure boosting facilities are required to maintain the plateau – with a goal of achieving a 90% gas recovery factor – and increase production beyond the end of the plateau by lowering pressure at the Khuff reservoirs.

Wabag confirms $372m Kuwait desalination contract26 August 2026
India's VA Tech Wabag has confirmed it has signed a contract to supply, install, operate and maintain the second phase of the Doha seawater reverse osmosis (SWRO) desalination plant.
Wabag confirmed the signing in a Regulation 30 filing on 25 August to the National Stock Exchange of India and BSE Limited.
The contract is valued at KD114.28m ($372m) and will be delivered by a Wabag-led unincorporated joint venture with Kuwait’s Heavy Engineering Industries & Shipbuilding Company (Heisco).
In April, MEED reported that Kuwait’s Central Agency for Public Tenders had approved the recommendation of the Ministry of Electricity & Water to award the contract to the joint venture.
It is understood that the decision then had to go through final approval from the Audit Bureau
The project will deliver a production capacity of about 60 million imperial gallons a day (MIGD) equivalent to about 272 million litres a day.
It will include the desalination plant with full reverse osmosis trains, pre- and post-treatment systems, recarbonation equipment, booster pumps, and safety and filtration systems. On-site solar photovoltaic systems will also provide part of the plant’s energy requirements.
According to the filing, construction is scheduled to take 36 months, followed by a five-year operation and maintenance period.
The Doha SWRO desalination plant is part of Kuwait’s broader programme to expand water production capacity and reduce reliance on thermal desalination methods.
As reported by MEED, the Heisco/Wabag joint venture submitted the lowest of three bids for the project in August 2025.
In April 2025, MEED reported that Kuwait had retendered the contract for the facility after the ministry cancelled the initial tender in June 2024.
The Ministry of Electricity & Water awarded South Korea’s Doosan Heavy Industries & Construction – now known as Doosan Enerbility – a $422m contract in May 2016 to build the 60 MIGD Doha 1 SWRO plant.
The contract marks Wabag's first project in Kuwait. In June, the contractor also won its first major contract in the UAE for the Ajman sewage biorefinery plant phase 3 project.
