The Challenge
Increase the storage and power performance of the existing Coo pumped‑storage plant by 7.5% while safeguarding reliable operations for the next 40 years. The upgrade had to be conceived and delivered on a live, grid‑critical asset, balancing stringent technical, scheduling and regulatory requirements.
The Solution
Modification and expansion of the spillway and flood release facilities.
The Impact
Extended lifetime and increased capacity, reinforcing Belgium’s grid flexibility.
