Permit final for GES BESS project Sequoia (200 MW / 800 MWh)

Permit final for GES BESS project Sequoia (200 MW / 800 MWh)

Green Energy Storage (GES) has reached an important milestone in the development of large-scale energy storage in the Netherlands. The permit for battery storage project Sequoia has become final and irrevocable. This means the project is fully licensed and ready for the realization phase.

Sequoia involves a large-scale Battery Energy Storage System (BESS) with a capacity of 200 MW and a storage capacity of 800 MWh. The project will be located in the municipality of Oosterhout and will be connected to TenneT's 150 kV substation in Geertruidenberg. Sequoia is designed as a long-term energy infrastructure and was specifically developed as a congestion reliever.

By absorbing and returning power at strategic moments, Sequoia actively contributes to relieving the burden on the electricity grid. As such, the project plays an essential role in increasing the flexibility, reliability and stability of the Dutch electricity system.

Crucial link in the energy system

The rapid growth of renewable energy is greatly increasing the need for flexibility and balance in the electricity grid. Sequoia is designed to meet this need by providing FCR and aFRR services as well as actively contributing to congestion relief.

By taking in and delivering power at strategic times, Sequoia helps to relieve the grid and use renewable generation more efficiently.

With this project, GES is contributing to a robust and reliable energy system in which large-scale energy storage plays a structural role.

The new giant of the energy system

With Sequoia, GES deliberately chose a name that goes beyond a project label. The name refers to the redwood tree: one of the oldest and most powerful trees in the world, known for its ability to withstand extreme conditions and keep ecosystems in balance.

Those characteristics are at the heart of how GES approaches battery energy storage: as quiet, robust infrastructure that supports and strengthens the energy system. Not as a temporary solution, but as a long-term structural foundation.

Project Features Sequoia

• Power: 200 MW

• Capacity: 800 MWh

• Grid connection: 150 kV TenneT-station Geertruidenberg

Installation layout

• 224 battery containers

• 53 medium voltage transformers

• 1 high-voltage transformer (150 kV / 33 kV)

Built for the long term

Sequoia represents strength, stability and durability. Designed as long-term infrastructure, the project is the first within a broader portfolio of GES developments inspired by timeless forces of nature.

With this line, GES is building a recognizable family of projects: the new giants of the energy system.

Next step: realization

With the permitting process completed, the focus now shifts to the realization phase. GES is thus taking another step in its mission to develop large-scale energy storage as a foundation for energy transition.
