Context and challenges

This major industrial city was born from the ambition of Saudi Arabia to see the country develop into a pioneering and thriving model of excellence in various and important sectors. This project deals with a leading global hub through value chains of industry and technology.

The industrial city will cover hundreds of km² of land.

In this context, this client, the company set up for the construction of this industrial city, has appointed Assystem to perform area assessment, site screening and Site Characterization services for the construction of a PhotoVoltaic (PV) Power Plant.
