Let's discuss your project
Grids need to cope with increasing amounts of distributed, variable renewable energy generation.
When the grid cannot absorb all the electricity generated, for example from renewable sources, the challenge is to store the energy for later use.
Saft’s battery energy storage solutions are capable of stacking multiple grid services, including:
- Frequency regulation
- Inertia support
- Voltage support
- Congestion avoidance
- Optimized dispatch management
We assist customers from inception to implementation and operation of their energy storage system.
Saft designs the optimal system solution in terms of installed power (MW) and energy (MWh) to enable stacking of multiple services with high daily energy turnover.
A deep understanding of aging mechanisms enables Saft to model, predict and control battery health, even under complex and evolving operating patterns. In this way, Saft ensures and guarantees effective operation over the lifetime of the system to secure long-term project returns for customers.
Saft provides turnkey solutions up to hundreds of MW, integrating a Saft lithium-ion battery system with power conversion devices, power control and energy management functions.
Saft's developments comprise two main product lines: Intensium® Shift for 2 to 8 hour energy shifting applications and Intensium® Max for 1 to 2 hour dynamic grid services.
A world record for Saft's grid batteries, registered by the Guinness Book of Records in 2003.
47MW is the Guinness World Record for Saft's first grid-supported BESS installed in Alaska in 2003. The system is still in operation today and has prevented thousands of power outages in the harshest Arctic conditions.

Transmission and distribution grids are crucial to transit large amounts of wind and solar energy. Our battery energy storage solutions seamlessly integrate multiple and innovative grid services, offering operators the flexibility to ensure stable and resilient grid operation.
