Muscat: The company confirmed that work on the strategic Rabt Project (Phase II) has surpassed 60 per cent completion, representing an investment of RO 295 million. Expansion projects in the Dhofar Governorate have advanced even further, exceeding 90 per cent completion at a cost of nearly RO 65 million. Meanwhile, more than 50 per cent progress has been achieved on the landmark Masirah Island grid connection project, valued at RO 70 million, marking the first initiative of its kind in Oman using advanced and complex transmission technologies.

Additional milestones include the launch of a fault current limiting system on the 132 kV network, aimed at reducing technical faults, protecting transformers and enhancing grid reliability. The system also supports the operation of the main transmission station serving the polysilicon factory project in Sohar.

The company’s broader expansion strategy will see investments exceeding RO 1 billion by 2030, aligning with national development plans and rising electricity demand across sectors. Since its establishment, Oman Electricity Transmission Company has significantly expanded the national grid, increasing the number of transmission stations from 29 in 2005 to 116 today, a rise of 300 per cent, while transmission line lengths have grown by 288 per cent to more than 10,400 kilometres.

In 2025 alone, the company launched nine new projects worth over RO 250 million, expected to reduce carbon emissions by more than 1,914 tonnes annually. These include efforts to connect three wind power stations with a combined capacity of 1,220 megawatts and a 500-megawatt solar power project, supporting Oman’s net-zero neutrality target by 2050, reducing gas consumption and strengthening renewable-linked industries.

Operational reliability has reached 99.9999 per cent by the end of November 2025, despite record demand. Peak loads on the main grid rose to 8,059 megawatts, up from 2,495 megawatts in 2005, while Dhofar’s peak load climbed to 881 megawatts and Musandam recorded 99 megawatts this year.

Renewable energy contributions to the grid increased to 9.46 per cent, delivering more than 4.26 million megawatt-hours by November 2025 from projects including Ibri Solar, Manah 1, Manah 2, and the Dhofar Wind Power Station, compared to just 0.71 per cent in 2019.

On the financial front, the company maintained strong credit ratings, Ba1 (stable) from Moody’s and BB+ (stable) from Fitch, while successfully repaying US$1 billion in Lamar bonds and issuing the Sultanate’s first five-year green bonds worth US$750 million. Asset values have surged by over 870 per cent since 2005 to reach RO 1.8 billion in 2025.

During the year, the company received 38 new grid connection requests, bringing the total since 2017 to 125, while localisation levels reached 97 per cent through continuous investment in training and national talent development. Tenders awarded to local firms in 2025 exceeded RO 259 million, including 33 contracts to SMEs holding the Riyada card.

Engineer Hisham bin Abdullah Al-Riyami, Acting CEO, said the achievements reflect accumulated expertise, advanced technologies and global collaboration aimed at enhancing reliability and sustainability. He reaffirmed that the company remains responsible for electricity transmission and control across all governorates, including managing the 220 kV interconnection with the Gulf Interconnection Network, ensuring Oman remains firmly powered for future growth.
