Job description

ACWA Operations

At Acwa Operations, we make essential services dependable and efficient for the millions of people who rely on them every day. Formerly NOMAC (The First National Operations & Maintenance Company), we are the operations and maintenance arm of Acwa, focused on keeping power generation and water desalination assets running safely, reliably and cost-effectively across their full lifecycle. Since 2005, we have partnered with clients across the Middle East, Africa and Asia to support complex infrastructure that powers communities and sustains economies.

Marafiq Red Sea Project

The Red Sea Utilities Multi-Utilities Project is a landmark greenfield initiative developed by ACWA Power in partnership with Red Sea Global, supporting Saudi Arabia's premier tourism destination along the Red Sea coast. Under a 25-year Utilities Concession Agreement, ACWA Power is responsible for the development, construction, operation, and eventual transfer of a fully integrated, off-grid utilities infrastructure. The project includes a 340 MWac solar PV plant combined with one of the world's largest captive-scale battery energy storage systems (1,000-1,200 MWh), enabling 24/7 clean energy supply. In addition to renewable power, the scope covers seawater desalination (up to 32,500 m³/day), wetlands-based sewage treatment (16,000 m³/day), district cooling (32,500 RT), and zero-landfill waste management (~11,775 t/year). With financial close reached in early 2022, backed by international and local lenders and supported by the Public Investment Fund (PIF), the project represents a pioneering model of sustainable infrastructure aligned with Saudi Arabia's Vision 2030 and the Red Sea destination masterplan.
