OETC earmarks $2.2 billion for Oman's grid infra expansion by 2028
Majority state-owned Oman Electricity Transmission Company (OETC), the operator of the country's national grid, says it has budgeted an expenditure of $2.2 billion towards the execution of as many as 32 key projects over the 2024 – 2028 timeframe – projects that are necessary to integrate, expand and modernise Oman's critical power transmission and dispatch infrastructure.
The investment is also key to enabling the evacuation of renewable power from a host of new solar and wind energy projects planned for development across the country. This sizable allocation comes on top of a capex of $1.2 billion already made by OETC towards a slate of grid expansion projects implemented over the 2019-2023 timeframe, the company stated in a new report.
Both sets of projects are 'designed for the evacuation of new generation capacity and support load growth and system security standards,' said OETC. It cited in this regard its central role in managing the intermittent nature of renewable energy as Oman prepares to ramp up the share of clean energy generation from 5.9 per cent of total capacity as of 2024, to 32.7 per cent by 2028. Renewable energy's component is projected to further rise to 70 per cent by 2040.
To achieve this target, Nama Power and Water Procurement Company (PWP) – the sole procurer of new capacity and offtaker of output – aims to procure more than 4 GW of solar and wind-based Independent Power Projects (IPP) across the country by 2029.
OETC also noted that its North-South Interconnect Project (Rabt) will increase access to vast areas of the country with renewable energy potential, once the Main Interconnected System (MIS) in the north and Dhofar System in the south are integrated. Rabt will also play a vital role in conserving the environment and achieving Oman's Net Zero Emissions (NZE) target by 2050, in line with the Omani government's drive to switch to renewable energy.
'The Rabt Project aims to increase efficiency, integration, and security of the national electricity transmission network while reducing carbon emissions. The project's estimated reduction in carbon emissions is expected to exceed 474,000 tonnes per annum following the closure of 14 diesel operated plant, which will also save more than 175mn litres of diesel on an annual basis, thus reducing costs by more than $170 million,' the grid operator added.
OETC is 51 per cent owned by state-run Nama Holding, and 49 per cent by State Grid International Development Ltd (SGID), which is part of the wholly Chinese-owned State Grid Corporation of China, the world's largest transmission network operator.
OETC's grid infrastructure consists of an Extra High Voltage (EHV) transmission network covering over 95 per cent of Oman's electricity market. Its 113 grid stations are interconnected by 132kV, 220kV and 400kV overhead lines and underground cables. The transmission network has expanded from 3,806 km of power lines at the end of 2010 to over 10,066 km at the end of 2023.

Workshop held to highlight Oman's circular economy gap calculation project
Muscat: The Ministry of Economy on Monday organised the second workshop on the "Circularity Gap Report - Oman." This initiative aims to develop a national roadmap for the circular economy. Dr. Nasser Rashid Al Maawali, Undersecretary of the Ministry of Economy, clarified that the project to calculate the circular economy gap in Oman is the first of its kind in the Middle East and North Africa. This underscores Oman's commitment to achieving net-zero emissions by 2050. In a press statement, the Minister explained that this crucial national project has three main objectives: establishing a national baseline to measure the circular economy gap and compare it with other countries, designing a circular economy roadmap for Oman, and empowering and enhancing national capabilities in the circular economy sector for both public and private entities. Al Maawali affirmed that the project will foster sustainable, low-carbon economic development and create new investment opportunities in renewable areas related to alternative energy and the green economy. Earlier in the workshop, Ahmed Said Al Siyabi, Director General of Economic Policies and Programs at the Ministry of Economy, delivered a speech. He emphasised that the workshop aimed to review and discuss the preliminary results of calculating the baseline for the circular economy gap across various sectors. He added that the workshop also introduced accompanying initiatives, such as training programs and a proposed interactive platform to showcase project results and outputs. Furthermore, the workshop presented preliminary models illustrating the impact of applying circular economy policies on environmental and economic indicators, including employment opportunities. During the workshop, visual presentations showcased developments in the study to calculate the circular economy gap in Oman, along with a presentation and discussion of the project's preliminary results. Attendees also participated in group discussions to present and analyse models and scenarios for measuring the impact of implementing circular economy strategies and policies on environmental impact and job opportunities. The significance of the circular economy lies in its pivotal role in promoting sustainability, efficient resource utilisation, waste reduction, and recycling as a sustainable model, moving away from the traditional resource-depleting model.

Renewables share of Oman's total power output climbs to 11.5%
MUSCAT: The contribution of solar and wind capacity to Oman's total electricity generation more than doubled to approximately 11.5 per cent during the first five months of this year (January–May), up from around 4.88 per cent at the end of December 2024. According to Nama Power and Water Procurement Company (PWP), the sole procurer of electricity and water capacity in the Sultanate of Oman, renewable energy—predominantly from solar sources—accounted for 1.88 terawatt-hours (TWh) during the January–May 2025 period. This compares with total renewable output of 2.4 TWh for the whole of 2024. Furthermore, around 89,840 households were supplied with clean electricity during the five-month period, resulting in annualised emissions reductions of approximately 617,300 tonnes, Nama PWP added. This rapid increase in renewable generation supports the Omani government's strategy to achieve a clean energy share of around 30–40 per cent of total generation capacity by 2030, rising to 60–70 per cent by 2040. The target is for 100 per cent clean energy generation capacity by 2050. Currently connected to the national grid are the following utility-scale renewable energy projects: Dhofar I Wind Farm (50 MW), Ibri II Solar IPP (500 MW), and the Manah 1 and Manah 2 Solar IPPs (1,000 MW combined). Next to join the grid is the Ibri III Solar IPP (500 MW), which is currently in early development. In the next phase of renewable energy development, Oman is shifting its focus to wind power, with five wind farms—together representing over 1 gigawatt (GW) of capacity—currently under competitive tendering, overseen by Nama PWP. These projects are planned for Jaalan Bani Bu Ali, Duqm, Mahoot, Dhofar, and Sadah. The total investment in these Independent Power Projects (IPPs) is estimated at around RO 450 million (approximately $1.2 billion). Also in the pipeline is a series of new solar IPPs, aggregating around 4,500 megawatts (MW) in capacity and requiring an estimated investment of $2.8 billion. At least four new solar projects are envisioned for implementation over the next six years. The largest of these is the so-called 'Solar PV IPPs 2030'—a mega-project comprising one or more developments with a combined capacity of 3 GW. A Request for Proposals (RfP) for this groundbreaking scheme—estimated to cost between $1 billion and $1.5 billion—is expected to be issued in Q1 2027, with commercial operations anticipated by Q1 2030. Preceding this is the 'Solar PV IPPs 2029' initiative, centred on the development of a 1 GW capacity PV project, with a projected investment of $600–800 million. It is slated to begin operations in Q1 2029. Additionally, Sinaw in the North Al Sharqiyah Governorate is expected to host a 250–300 MW solar PV project, valued at around $200–250 million. The plant is scheduled to come online by Q2 2028. Recently, Nama PWP launched a competitive tender for a 280 MW solar IPP at Al Kamil in South Al Sharqiyah Governorate. Estimated at $200–250 million, this project is expected to be operational by Q1 2028.
