OETC completes fault current limiter project
MUSCAT: Oman Electricity Transmission Company (OETC) announced the successful completion of all construction and commissioning works for the Fault Current Limiter (FCLR) project on the 132kV transmission network in Muscat. The project has a total investment value exceeding RO 4 million. The Fault Current Limiters (FCLs) are installed to limit fault current to a safe level without interrupting the circuit, thereby protecting transformers, circuit breakers, cables, and other infrastructure from excessive thermal and mechanical stress.
They also help avoid costly equipment upgrades when fault levels exceed design ratings due to system growth or new network interconnections, and ensure the overall stability, safety, and reliability of the electricity network while maintaining uninterrupted power supply to other parts of the grid.
This project is part of OETC's ongoing efforts to enhance the sustainability and resilience of the national transmission network, in line with the company's strategic objectives to improve efficiency, reduce system failures, and ensure swift emergency response using modern smart technologies and global best practices.
Commenting on the achievement, Eng Masoud bin Salam al Riyami, Chief Operations Officer at OETC, stated: "This project marks a significant milestone in improving operational efficiency and the quality of power supply. It reflects our commitment to investing in smart infrastructure that ensures optimal grid performance and meets national energy development goals."
He further highlighted the company's strategic five-year plans to assess network conditions and implement both current and future projects aimed at building a world-class smart grid capable of adapting to growing demand and sectoral transformation. "OETC is fully committed to continuous development, cost-effective investments, and adopting high-standard systems to maintain a reliable and sustainable power transmission network. The FCLR system is a key step in that journey," Al Riyami added.
OETC, a member of Nama Group, is the only company responsible for the transmission and control of electricity across the Sultanate of Oman's network. The electricity is transmitted from production stations to distributed load centers in the governorates. The transmission network operates at a voltage of 132kV and above to cover All of the governorates in the Sultanate of Oman. Furthermore, OETC manages the interconnections between Oman and the GCC interconnection network, which operates at a voltage of 220kV.

The projects span industrial, logistics, and service sectors.

Al Abroui noted ongoing key projects, including the infrastructure works for the Madayn Pioneering Complex, developed in partnership with the Authority for SME Development, across more than 60,000 square metres. This initiative aims to create a fully serviced SME zone, with subdivided workshops of 500 square metres each. Additionally, a consultancy project is underway to address stormwater drainage challenges, including new roadworks to improve access to leased plots and other urban enhancements. Further initiatives include the redesign of the commercial area to house more retail units catering to investors and visitors. Among the upcoming projects is the establishment of an integrated facility to support food security, in coordination with the Ministry of Agriculture, Fisheries and Water Resources. Another planned project will focus on reusing treated wastewater for cooling and industrial purposes. Al Abroui also confirmed that beautification work on the city's main entrance will be completed by year-end. Since its inception in 1983, Rusayl Industrial City has served as a key enabler of Oman's economic diversification strategy. Its 'Masar' one-stop service centre simplifies investor procedures by streamlining approvals, permits, and licences — creating an integrated, investor-friendly environment aligned with Oman Vision 2040. — ONA
