12 February 2026

 

India’s Larsen & Toubro has won a contract to build the Majan 400/220/132kV grid station in Oman.

Estimated to cost $100m, the project includes an associated 400kV line-in line-out underground cable from Sohar Free Zone to the Sohar Interconnector Station.

The contract was awarded by Oman Electricity Transmission Company (OETC), part of the government-owned Nama Group.

The grid station will comprise eight 400kV gas-insulated switchgear (GIS) bays, eight 220kV GIS bays and 10 132kV GIS bays at the new Sohar Free Zone substation.

The scope includes the installation of two 500MVA, 400/220kV transformers and two 500MVA, 220/132kV transformers.

Local firm Monenco Consulting Engineers was appointed in April last year to provide design and supervision services for the project.

As MEED exclusively revealed, the main contract was tendered in June, as part of three significant contracts to build new substations in the sultanate.

The second contract, worth about $35m, covers the construction of the Sultan Haitham City 132/33kV grid station and associated 132kV line-in line-out underground cables running 4 kilometres from Mabella to Mabella Industrial Zone.

The third contract, valued at about $100m, covers the construction of the Surab 400/33kV grid station and an associated 400kV line-in line-out cable from the Duqm grid station to the Mahout grid station. 

Local firms Muscat Engineering Consulting and Hamed Engineering Services are consultants for the Sultan Haitham City and Surab projects, respectively.

The two remaining contracts are currently under bid evaluation, with awards expected this quarter.
