Contractors to start Rumah 1 and Nairiyah 1 work

29 January 2025

 

The engineering, procurement and construction (EPC) contractors for the  Rumah 1 and Nairiyah 1 combined-cycle gas turbine (CCGT) projects in Saudi Arabia are preparing to start construction work.

The start of construction will follow the issuance of a limited notice to proceed by the developer team to the EPC contractors, comprising a team of China’s Sepco 3 and South Korea’s Doosan Enerbility.

The Rumah 1 and Nairiyah 1 independent power projects (IPPs) will each have a capacity of 1,800MW.

A consortium comprising Saudi Electricity Company (SEC), Riyadh-based utility developer Acwa Power and South Korea’s Korea Electric Power Corporation (Kepco) won the contract to develop the two CCGT IPPs.

The developer consortium signed the power-purchase agreements (PPAs) for the two projects with the principal buyer, Saudi Power Procurement Company (SPPC), in November last year. 

According to a local media report, the SEC, Acwa Power and Kepco team offered a levelised electricity cost (LCOE) of $cents 4.5859 a kilowatt-hour (kWh) for Rumah 1, and $cents 4.6114/kWh for Nairiyah 1.

Acwa Power said in a statement that the two IPP facilities will require a combined investment of approximately SR15bn ($4bn).

The IPPs are expected to reach commercial operations in Q2 2008. 

Tokyo-headquartered Mitsubishi Power will supply the gas turbines to power the two plants.

Rumah 1 is located in the Central Region in Riyadh and is part of the previously planned Riyadh Power Plant 15 (PP15). Nairiyah 1 is located in the Eastern Region.

SPPC received bids for the contracts for four thermal IPPs – the other two being the similarly configured Rumah 2 and Nairiyah 2 – in August last year.

SPPC previously indicated that the four power plants would operate using natural gas combined-cycle technology with a carbon-capture unit readiness provision.

The four power generation facilities will be developed using a build-own-operate (BOO) model over 25 years. 

SPPC’s transaction advisory team for the Rumah 1 and 2 and Al-Nairiyah 1 and 2 IPP projects comprises US/India-based Synergy Consulting, Germany’s Fichtner and US-headquartered Baker McKenzie.
