Chinese firm signs deal for 4GW Saudi solar project

24 November 2025

Chinese firm Arctech has announced a cooperation agreement with PowerChina Huadong Engineering for the 4.2GW Afif solar photovoltaic (PV) project in Saudi Arabia.

The partnership will involve Arctech supplying its SkyLine 2 single-axis tracking system, designed to follow the sun in high-wind and desert environments.

Located near Riyadh, the Afif solar complex forms part of the Public Investment Fund’s (PIF) 15GW renewables programme announced earlier this year.

It comprises two independent power projects (IPPs): Afif 1 (1.8GW) and Afif 2 (2.4GW). PowerChina Huadong is the engineering, procurement and construction (EPC) contractor for both schemes.

In October, a consortium of Acwa Power, Water & Electricity Holding Company (Badeel) and Saudi Aramco Power Company (Sapco) reached financial close on five solar IPPs under the PIF programme, including Afif 1 and Afif 2.

The deals were signed at the ninth Future Investment Initiative (FII) conference in Riyadh.

The five projects have a combined value of about $6.4bn and a total capacity of more than 12GW. They include the 3GW Bisha solar IPP, the 3GW Humaij solar IPP and the 2GW Khulis solar IPP.

India’s Larsen & Toubro is the EPC contractor for the Bisha and Humaij solar projects.

China Energy Engineering Corporation (CEEC) recently signed the EPC contract for the 2GW Khulis solar PV project. 

The firm also signed EPC contracts for the two remaining projects in the renewables package, the 1GW Shaqra wind project and the 2GW Starah wind project, reaching $2.75bn in contracts across the three projects.

All schemes under the 15GW PIF renewables package are scheduled to begin operating between the second half of 2027 and the first half of 2028.
