GIGA Storage, a leader in battery energy storage, and Dutch grid operator TenneT have achieved a significant milestone by signing the first-ever time-based grid connection contract. This innovative agreement allows GIGA Storage to connect its GIGA Leopard battery project, boasting a capacity of 300 MW and up to 1,200 MWh of storage, to the electricity grid, utilising available capacity more efficiently.
This groundbreaking contract, part of the national initiative to combat grid congestion, grants GIGA Storage the right to draw electricity from the grid or feed it back into the system at least 85 per cent of the time.
This flexible approach addresses the growing challenge of grid congestion and offers a more economical solution for large energy consumers by providing up to a 65 per cent discount on transmission tariffs. The contract enables better use of grid capacity during off-peak hours, supporting the integration of renewable energy sources when sunlight and wind are limited.
TenneT CEO Manon van Beek highlighted the importance of this agreement in enhancing the electricity grid’s efficiency and reliability. By leveraging large-scale batteries like GIGA Leopard, the grid can maintain stability and balance, reducing reliance on traditional fossil fuel power plants.
Also, GIGA Storage CEO Ruud Nijs echoed these sentiments, noting that the collaboration demonstrates how innovative contracts can drive the energy transition forward, contributing to a more sustainable and stable energy supply.
Starting on October 1, 2025, this contract marks a new era in grid management, offering a viable alternative to traditional fixed transmission agreements. The Dutch Authority for Consumers and Markets (ACM) approved these time-based contracts in July 2024, providing a flexible option for large business customers like GIGA Storage while optimising grid capacity for future needs.
