The Oman Electricity Transmission Company (OETC), a member of Nama Group, has signed a number of agreements, worth over $475 million, for the implementation of the first phase of the “Rabt” project that aims to connect the country’s northern and southern grids.

The signing of these agreements aims to connect the national grid in the north with (PDO) electricity transmission network and Tanweer network in Al Wusta region in addition to SEZAD electricity network in the Willayat of Duqm.

This phase of the project will pave the way for connecting the national grid in the north of Oman with Dhofar electricity transmission network which will be implemented in the second phase of Rabt project. The project is expected to enhance the efficiency and integration of the national electricity transmission networks.

The project will also play a key role in securing the electricity network and opening up new horizons for the use of renewable energy sources such as wind and solar which are abundant in Al Wusta region. The project will connect isolated areas from the main system such as Haima, Duqm and Mahoot with the national grid.

It will also connect the national grid with PDO network thus enhancing the reliability of PDO network as it is currently based on 132 kV voltage. The project will help minimizing the use of gas in electricity generation in PDO electricity network as the electricity generation stations in the National Grid are relatively new and highly efficient. Moreover, the project will help in reducing the cost of energy produced in Duqm and Mahoot using diesel due to its high cost and its negative impact on the environment.

In-line with the Government drive to switch to renewable energy, this project will play a key role in achieving the government ambitions of producing 15% of the total energy from renewable energy sources by 2025 by connecting the future solar energy stations and wind farms in theAl Wusta region.

The Rabt project will also provide secure, stable and reliable electricity to Special Economic Zone in Duqm as it will connect the Duqm Electricity network with the 400 kV National Grid, ensuring that the factories and large companies in Duqm are provided with their needs of electricity which will further help attracting more investors to the Area, provide more employment opportunities and help growing the national economy.

The first phase of the project consists of 660 km 400 kV overhead lines, five main grid stations in Nuhaida, Barik, Suwaihat, Duqum and Mahoot. The total cost of this phase is over $475 million and divided into five projects.

The first project entails the construction of 400 kV grid stations at Barik and Suwaihat and linking them to Petroleum Development Oman (PDO) network. Barik station consists of twelve 400 kV gas insulated switchgear bays, two 132/400 transformers with a capacity of 500 Megavolt Ampere for each of them.

This project also involves the installation of ten 132 kV gas insulated switchgear bays, four shunt reactors, Control and relay panels and communication instrument in addition to associated construction works. Suwaihat Station on the other hand consists of twelve 400 gas insulated switchgear bays, two 132/400 kV transformers with a capacity of 500 Megavolt Ampere for each of them in addition to twelve 132 kV gas insulated switchgear bays, six shunt reactors, control and relay panels and communication instrument in addition to associated construction works.
