Giga Buffalo
GIGA Storage BV + Wärtsilä

Reference case

Optimising the Dutch power system with energy storage

Wärtsilä has supplied GIGA Storage BV with a 25 MW / 48 MWh energy storage system, the largest energy storage system in the Netherlands to date, that optimises the power system, regulates energy frequency and reliability on the grid, and improves revenues.

The GIGA Buffalo battery stores the equivalent of the annual energy consumption of more than 9,000 households each year and saves up to 11,000 tonnes of carbon dioxide emissions per year (compared to a coal plant).

The system employs Wärtsilä’s GridSolv Quantum, a fully integrated, modular, and compact energy storage system. Wärtsilä’s GEMS Digital Energy Platform, a smart energy management system, uses machine learning and historic and real-time data analytics to optimise the complete system. GEMS software enables GIGA Storage BV to remotely monitor, operate, identify, and diagnose equipment with unrivaled safety, reliability, and flexibility. Finally, the system is optimised by Wärtsilä’s Service+ GAP solution, which provides comprehensive system maintenance with performance guarantees.
