Providing flexibility for the Belgian grid

Maintaining energy frequency and reliability

The Ruien Energy Storage project is Wärtsilä’s first in Belgium and one of the largest systems in the country to-date. The 25 MW / 100 MWh energy storage system helps the customer to regulate fluctuations and supply peak power with stored renewable energy in the grid. With improved reliability, the system also improves revenues.

Reliable and optimised electricity supply

The project utilises Wärtsilä’s Quantum energy storage system and sophisticated energy management software, the GEMS Digital Energy Platform. GEMS ensures optimal performance for the energy supply across a range of specified use-cases, including reserve power, frequency control response, capacity dispatch, and voltage support.

The system also has comprehensive system maintenance with performance guarantees across 15 years with Wärtsilä’s Service+ GAP solution.

Ruien Energy Storage is primarily designed and owned by Nippon Koei Energy Europe B.V. and Aquila Clean Energy, who developed the joint venture project.

MWh of energy storage capacity

This project is notable for Wärtsilä as our first project in Belgium, and another important milestone on adding state-of-the-art flexibility to the power system. We see a major opportunity and paramount need to increase deployment of energy storage in Europe, allowing to harness the full benefit of intermittent renewable energy across the continent.
