TeraStor Energy is an American energy storage company that designs and delivers battery energy storage systems (BESS) for the world’s most demanding energy infrastructure. Its system design, battery controls and software are US-owned, and it works with global manufacturing partners. US production, including through a collaboration with Foxconn, is planned for late 2027.

TeraStor offers two product architectures. Product Line S (Series-before-Parallel) delivers cost-effective, right-sized storage for commercial and industrial sites, campuses and microgrids, ranging from the 261 kWh S300 to the utility-scale S4000 and S5000-US. Product Line P (Parallel-before-Series) is built for data centers, grid-scale and mission-critical applications where downtime is not an option. Its flagship P8000 provides 8.2 MWh of capacity and can be ready for commissioning in under six hours.

Every system runs on StorOS™, TeraStor’s proprietary software stack, which spans from the cell to the cloud. StorCore™ BMS handles cell-level monitoring and protection, StorView™ EMS manages site-level dispatch, and StorCloud™ provides remote fleet monitoring. TeraStor is also developing StorAIQ™ for forecasting, dispatch optimization and predictive health.

The result is one accountable partner across the full lifecycle, from system design and manufacturing through commissioning, monitoring and long-term support. Every system is engineered for safety, performance and long service life.
