Rabigh 2 power plant

The 2,100MW combined-cycle Rabigh-2 independent power project (IPP) located next to the existing Rabigh-1 power plant, 130km north of Jeddah, Saudi Arabia, is being developed by Saudi Arabia’s state-owned utility Saudi Electric Company (SEC).

The gas-fired thermal power plant is being built on a build, own, and operate (BOO) basis and is expected to commence operations in 2017.

The SAR 5.973bn ($1.6bn) Rabigh-2 power project is an extension to the existing 1,024MW Rabigh power plant, which was inaugurated in June this year.

Al-Mourjan for Electricity Production Company has been established to develop, own and operate the power plant, as part of a 50:50 joint venture between SEC, and a consortium comprised of ACWA Power, Samsung C&T and MENA Infrastructure Fund.

Siemens supply gas turbines for Saudi Arabian Rabigh 2 CCPP

Siemens Energy received an order from Samsung CT to supply six gas turbines, three steam turbines and nine generators for the Rabigh-2 combined-cycle power plant (CCPP).


Rabigh-2 will comprise three 686.5MW combined-cycle power blocks designed as multi-shaft configurations. Each block will feature two SGT6-5000F series gas turbines, three SGen6-1000A-series electrical generators, and a SST6-5000 series HI-L steam turbine.

SGT6-5000F is a four-stage gas turbine featuring a 13-stage axial compressor with advanced 3D design technology, three rows of variable inlet guide vanes, advanced cooling technology, and a syngas combustion system (IGCC). It has a base power output of 232MW and will operate at a gross efficiency rate of 38.8%.

Rabigh-2 will be the first IPP in Saudi Arabia to utilise the combined-cycle technology with a thermal efficiency of 58.8%. It will use natural gas as the main fuel and super-light Arabian crude oil as back-up fuel.

The gas-fired, combined cycle power project will operate in accordance with the environmental laws, regulations and standards of World Bank, IFC and the Saudi Presidency of Meteorology and Environment.

Financing the combined-cycle power plant project

“Rabigh-2 will utilise combined-cycle technology with a thermal efficiency of 58.8%.”

About 74% of the Rabigh-2 project cost is being met through a senior debt facility, provided by a group of international and local banks, including Standard Chartered, KfW-IPEX Bank, Mizuho Bank, Banque Saudi Fransi, Al Rajhi Bank, National Commercial Bank, Samba Financial Group and Al-Inma Bank. The remaining 26% will be financed through equity bridge loans.

Rabigh-2 power off-take

The entire electricity produced from Rabigh-2 will be purchased by SEC for a period of 20 years under a power purchase agreement (PPA) signed in November 2013. SEC, in return, will provide fuel, seawater intake and associated facilities and infrastructure.

Contractors involved in Rabigh-2

Samsung C&T was awarded the $1.2bn engineering, procurement and construction (EPC) contract for the Rabigh-2 power project in December 2012.

Siemens was awarded the contract to supply six gas turbines, three steam turbines and nine generators for the plant in April. The contractual scope also includes support services for erection and commissioning of the plant as well as long-term maintenance service for the turbines.

BHI, a licensee of Foster Wheeler’s Global Power Group, was awarded the contract to supply six heat recovery steam generators (HRSG) for the project. BHI will also supply pulverised coal (PC) boilers, circulating fluidised bed (CFB) boilers and oil and gas boilers for the Rabigh-2 plant.

First National Operation and Maintenance Company (NOMAC), a subsidiary of ACWA Power, will operate and maintain the plant under a long-term operation and maintenance (O&M) contract.
