35 projects worth RO 250 million power Oman’s grid expansion

MUSCAT: The Oman Electricity Transmission Company has made strong progress in expanding and upgrading the national electricity transmission network, with 35 major projects currently under implementation at a total cost of around RO 250.2 million. These projects form part of a wider long-term strategy to strengthen grid capacity, reliability and readiness for future demand.
OETC reported that more than 60 per cent of the second phase of the strategic Rabt project has been completed, while network expansion projects in the Dhofar Governorate have surpassed 90 per cent completion. Significant progress has also been made on the landmark project to connect Masirah Island to the main transmission network, with more than half of the work completed using advanced and complex technologies. In addition, a fault current limiting system has been introduced on the 132 kV network to reduce outages, protect equipment and enhance supply security, while the main transmission station for the polysilicon factory project in Suhar has been commissioned.
The company’s phased expansion of the national grid is expected to continue through to 2030, with total investments exceeding RO 1 billion. These efforts are designed to support national development priorities and meet rising electricity demand across all sectors. Since its establishment, OETC has steadily expanded the network, increasing the number of transmission stations to 116 from just 29 in 2005, while network length has grown to more than 10,400 kilometres.

During 2025, OETC awarded nine new projects valued at over RO 250 million, many of which support the integration of renewable energy. These projects are expected to cut carbon emissions by more than 1.9 million tonnes annually and include the connection of three wind power plants with a combined capacity of 1,220 megawatts, alongside a 500-megawatt solar project. These initiatives contribute directly to Oman’s net-zero ambitions, optimise gas consumption and support the localisation of clean energy industries.
The reliability of the transmission network reached 99.9999 per cent by the end of November 2025, despite record demand. Peak load on the main grid rose to 8,059 megawatts, while renewable energy contributions climbed to 9.46 per cent of total electricity supplied, driven by solar and wind projects across Ibri, Manah and Dhofar.
Financially, OETC maintained strong credit ratings and advanced its green finance agenda by issuing the country’s first green sukuk. The company also repaid $1 billion in bonds and saw its asset base grow significantly. Alongside infrastructure development, OETC continued to invest in human capital, achieving an Omanisation rate of 97 per cent, while awarding over RO 259 million in tenders to local firms, including a significant share to SMEs.
Engineer Hisham bin Abdullah al Riyami, Acting CEO of OETC, said the achievements reflect years of accumulated experience, technological adoption and strong engagement with global industry leaders. He affirmed that the company remains committed to ensuring a reliable, secure and sustainable electricity transmission system that supports Oman’s national development goals and long-term energy transition. — ONA
