Overview
COO is a 1,164 MW hydroelectric power plant in Belgium, operational as a pumped-storage facility. It plays a key role in grid stability and renewable energy integration.
COO is a hydroelectric power plant located in Belgium, with a capacity of 1,164 MW. It is a pumped-storage facility, which allows it to store energy by pumping water to an upper reservoir and generate electricity during peak demand. The plant is operational and contributes significantly to Belgium's renewable energy capacity. As a pumped-storage hydroelectric plant, COO uses reversible turbines to both pump and generate electricity. This technology provides grid flexibility and supports the integration of variable renewable sources like wind and solar. The plant operates under Belgian and EU energy regulations, including the EU Renewable Energy Directive and the Industrial Emissions Directive, ensuring environmental compliance. The facility is strategically important for balancing the grid and providing ancillary services. Its large capacity makes it one of the largest pumped-storage plants in Europe. COO helps reduce reliance on fossil fuels during peak hours and supports Belgium's transition to a low-carbon energy system.
Environmental context
Hydroelectric pumped-storage plants like COO have a low direct carbon footprint but can affect local aquatic ecosystems due to water level fluctuations and barriers to fish migration. The facility is located in the Ardennes region, a forested area with significant biodiversity. Operations are regulated under EU water framework directives to minimize ecological impact.
Frequently asked questions
The COO hydroelectric power plant is located in Belgium, near the town of Trois-Ponts in the Ardennes region. Its coordinates are 50.3849 N, 5.8618 E.
The COO power plant has a capacity of 1,164 megawatts (MW), making it one of the largest pumped-storage hydroelectric facilities in Europe.
A pumped-storage hydroelectric plant uses two reservoirs at different elevations. During low demand, excess electricity pumps water to the upper reservoir. During peak demand, water is released to generate electricity. This provides grid stability and energy storage.
Hydroelectric plants in Belgium must comply with EU directives such as the Water Framework Directive (2000/60/EC) and the Environmental Impact Assessment Directive. These regulate water use, ecological flow, and fish passage to minimize environmental impact.
COO provides critical grid balancing services, storing excess energy from renewable sources and supplying power during peak demand. It enhances grid reliability and supports Belgium's renewable energy targets.
