Maximum renewable integration

Saft, a subsidiary of TotalEnergies, has developed a new high-energy density storage system (ESS) optimized for time-shifting applications. Modular Intensium Shift (I-Shift) 3MWh containers are scalable building blocks and can be installed in line-ups with power conversion equipment with a 50% smaller system footprint, while reducing 50% of site-related activities, allowing fast deployment of utility-scale storage plants. Four groups of twin line-ups with 48 I-Shift containers can provide a reliable 32MW/128MWh four-hour energy storage system with low land requirements and civil works’ needs. Available from mid-2023, I-Shift is based on lithium iron phosphate (LFP) technology. It is suited to energy time-shifting, peaking, and capacity support applications on transmission and distribution grids. Customers can use these individual 20ft containers with 3MWh storage capacity to handle the output of multi-megawatt sites for between two and eight hours, either co-located on renewable farms, or as standalone sites. I-Shift containers are fully populated in Saft’s factories and use a modular approach embedding batteries, thermal systems, and digital control interfaces connecting to Saft’s cloud-based data platform I-Sight. They include Saft’s fire suppression systems or blast panels. Saft provides 360° support from project inception and commissioning to end-of-life, dismantling and recycling of containers. Intensium Shift systems will be delivered from its three strategic manufacturing hubs for energy storage in France, US, and China.
