The Oman Electricity Transmission Company (OETC) has outlined the planned grid connection schedule for four 1GW solar independent power projects (IPPs) that will support the sultanate's renewable energy expansion through 2030.

The projects are detailed in OETC's Five-Year Annual Transmission Capability Statement (2026-30), which sets out the transmission infrastructure required to integrate new generation capacity into the national grid.

According to the report, the first of the four gigawatt-scale projects, the Adam solar IPP, is scheduled for integration in 2028.

Oman’s Nama Power & Water Procurement Company (Nama PWP) issued a request for qualification for the development of the Adam solar IPP in June.

OETC said it expects the 1GW Al-Kamil 2 solar project to be integrated in 2030 through the planned Sadaf 400kV grid station. The 1GW Dhofar solar IPP and 1GW Mahadha solar IPP are also scheduled for integration in 2030.

Before the gigawatt-scale projects are connected, several smaller utility-scale solar schemes are expected to enter service.

The first is the 500MW Ibri 3 solar project, supported by the Al-Sebkha 400kV switching station. Construction began on Ibri 3 in January.

The report says this will be followed by the Al-Kamil 1, Sinaw and Marsa solar IPPs.

The power purchase agreement for the 500MW Al-Kamil IPP was recently signed by a separate consortium comprising France's EDF Power Solutions, Oman National Engineering & Investment Company and the local OQ Alternative Energy.

Nama PWP has issued a supervisory consultancy tender for the 280MW Marsa IPP in North Al-Batinah Governorate, with a bid submission deadline of 26 July.

The transmission statement says about 70 transmission projects are expected to enter service between 2026 and 2030.

The programme is intended to increase transmission capacity, connect new renewable generation, strengthen grid reliability and support electricity demand growth across the sultanate.
