China-headquartered Shandong Electric Power Construction No. 3 Company (Sepco 3) and South Korea’s Doosan Enerbility have confirmed their involvement as contractors on the 1,700MW Misfah combined-cycle gas turbine (CCGT) project in Oman.

In a statement, Sepco 3 said it signed the contract on 20 August. On 21 August, Doosan disclosed a KRW930bn ($683m) contract with Jabel Power, the project company for the Misfah plant. The contract runs from 20 August 2026 to 1 April 2029.

The same consortium signed the engineering, procurement and construction (EPC) contract for the 890MW Duqm CCGT power plant in June. At the time, Doosan disclosed a contract worth about $350m.

In May, MEED exclusively reported that the group had been appointed as the main contractor for the two power plants, subject to the official signing.

State offtaker Nama Power & Water Procurement (Nama PWP) had previously signed power-purchase agreements (PPAs) for the development and operation of the plants.

The developer’s contract was awarded to a consortium comprising Korea Western Power (Kowepo), Qatar’s Nebras Power, the UAE’s Etihad Water & Electricity (EtihadWE) and Oman’s Bhawan Infrastructure Services.

As MEED understands, construction works have already commenced on the power plant projects. A China-based procurement listing in June shows that civil works procurement was under way for the Misfah independent power producer (IPP).

The civil package F tender covered piling, reinforcement cages, concrete works and pile testing, with work scheduled to start in July and finish by November

As reported in July, Germany’s Siemens Energy will supply power generation technology and long-term service agreements for the Misfah and Duqm IPP projects.

This includes the supply of six F-class gas turbines, six generators and 20-year long-term service agreements for the equipment.

The Misfah IPP will be led by Nebras Power and located in Wilayat Bousher in Muscat Governorate. The Duqm IPP will be led by Kowepo and located in Wilayat Duqm in Al-Wusta Governorate.

According to Nama PWP, the total investment for the two projects is estimated at approximately RO1bn ($2.6bn).

Synergy Consulting is the financial adviser and lead adviser to Nama PWP for these projects.

In November, Oman’s OQ Gas Networks received final investment approval to proceed with gas supply connections for the facilities.

The Misfah IPP will receive 8.5 million cubic metres a day (cm/d) of natural gas. The Duqm IPP will be supplied with 4.5 million cm/d of natural gas.

In March 2025, the same Sepco 3 and Doosan Enerbility consortium signed an EPC contract with Saudi Electricity Company to expand Riyadh Power Plant 12 (PP12). Located about 150 kilometres northwest of Riyadh, the 1,863MW power plant is expected to be completed in 2028.
