Saudi Arabia prepares to tender 9GW of thermal capacity

15 May 2025

 

Saudi Arabia’s main utility firm, Saudi Electricity Company (SEC), and the principal buyer, Saudi Power Procurement Company (SPPC), plan to tender the contracts to build and develop, respectively, combined-cycle gas turbine (CCGT) power generation plants before the end of the year.

According to industry sources, SEC is expected to invite engineering, procurement and construction (EPC) contractors to bid for a CCGT power generation plant in Shoaibah, while SPPC could start prequalifying bidders for a gas-fired independent power plant (IPP) located in Shuqaiq or Dawadmi.

One of the sources said the total capacity being considered is 9GW.

It is unclear if the SPPC will split the Dawadmi IPP into two contracts, similar to the four IPP schemes it awarded in 2023 and 2024, where each scheme was divided into two packages.

The project is part of the massive capacity buildout in Saudi Arabia as the kingdom implements its liquid fuel displacement programme by 2030 and aims for renewable energy to account for 50% of its total installed generation capacity by the end of the decade.

The SPPC awarded eight gas-fired IPP contracts with a total capacity of 14.4GW between 2023 and 2024.

SEC last year and during the first several months of this year awarded the contracts or issued the limited notices to proceed for six CCGT projects with a total combined capacity of nearly 14GW, exclusive of the 1.2GW Rabigh power plant project awarded in 2023 to a team led by Saudi utility developer Acwa Power.

These contracts bring the total capacity of under-construction gas-fired power generation plants in Saudi Arabia to roughly 30GW, including the 475MW cogeneration plant in Marjan. 

Solar and wind projects with a total capacity of around 16.4GW are also under construction in the kingdom.

In its 2024 earnings report, SEC said the kingdom’s generation capacity connected to the grid reached 92.15GW in 2024, up 6.9% over 2023, when installed capacity stood at 86.23GW.

The firm also said it aims to expand its power transmission network to approximately 160,000 kilometres by 2030, up 60% over its existing network of about 99,800km.
