Muscat – Oman Electricity Transmission Company (OETC) has made significant progress this year in implementing a package of vital projects aimed at expanding and developing the electricity transmission network. A total of 35 projects are currently underway at an approximate cost of RO250.2mn.
According to a report by Oman News Agency, OETC confirmed that these projects have achieved a completion rate exceeding 60% in the second phase of the strategic Rabt Project, valued at RO295mn.
Completion rates have surpassed 90% in the Dhofar Governorate’s network expansion projects, with a total cost of around RO65mn. Additionally, over 50% of the strategic project – the first of its kind in the sultanate to connect Masirah Island to the main transmission network using advanced technologies – has been completed, at an estimated cost of RO70mn.
Furthermore, the installation of a fault current rationing system on the 132kV network has been initiated to reduce outages, protect transformers and network components, and ensure the reliability and security of electricity supply. The main transmission station for the polysilicon factory project in Sohar has also been commissioned.
OETC’s strategic projects to expand the national grid continue in phases, in line with plans and directives, with a total investment expected to exceed RO1bn by 2030. This expansion aims to support national development across all sectors and realise the country’s long-term visions.
These initiatives respond to the sector’s growth and aim to meet the needs of comprehensive development. The number of electricity transmission stations has reached 116, compared to 29 in 2005, representing a 300% increase over 20 years. Similarly, the electricity transmission network now extends over 10,400 kilometres, up more than 288% from 2,680 kilometres in 2005.
This year, OETC also awarded nine new projects at a total cost exceeding RO250mn. These projects are expected to reduce carbon emissions by more than 1.914mn tonnes annually. They include connecting three wind power plants with a combined capacity of 1,220 megawatts and a 500-megawatt solar power project, contributing to net-zero ambitions by 2050, optimising gas consumption, and supporting industrial localisation in these key sectors.
In addition, OETC continues to support innovation and the adoption of modern technologies in network management and control. Its commitment to international standards, alongside the highest levels of workplace quality, health, and safety, has resulted in over 67mn safe work hours since the last lost-time injury.
These efforts have also increased the reliability of the electricity transmission network to 99.9999% by the end of November 2025, despite rising network loads. Peak loads on the main network reached 8,059 megawatts, compared with 2,495 megawatts in 2005, an increase of over 223%. Peak loads on the Dhofar network rose to 881 megawatts in 2025, up from 199 megawatts in 2005, while the Musandam network reached a peak of 99 megawatts this year. Renewable energy sources now contribute 9.46% to the electricity grid.
Regarding financial performance, OETC maintained high credit ratings, holding a Ba1 rating with a stable outlook from Moody’s and a BB+ rating with a stable outlook from Fitch. The company launched its green financing framework, successfully repaid its Lamar bonds totalling $1bn, and became the first Omani institution to issue green sukuk, with its inaugural five-year sukuk issuance valued at $750mn.
OETC continues to invest in human capital through specialised training programmes in technical, administrative, health, safety, and environmental fields, while fostering innovation and knowledge transfer. The company has achieved an Omanisation rate of 97%.
The total value of tenders awarded to local companies in 2025 exceeded RO259mn, comprising 85 tenders, 33 of which were awarded to small and medium enterprises (SMEs) holding Riyada cards. OETC has also increased its use of local products and supported Omani factories and SMEs in various projects, at an estimated cost of RO120mn from its existing project budget.
