Modular utility-scale energy storage with fast response supports peak shaving, load shifting, frequency regulation, voltage control and a broad range of grid-service revenue opportunities.
Across the range, SunTera provides fast active and reactive power response for frequency regulation, voltage control, capacity support and other grid services. G2 (5.01 MWh) is designed for high reliability, with AI-powered real-time diagnostics and system-level control strategies that significantly reduce auxiliary power consumption. G3 (6.25 MWh) is engineered to maximise project returns, combining higher system efficiency and usable capacity with five layers of active protection and dual-redundant gas and water fire suppression. G4 (7.76 MWh) features stacked-cell technology and end-to-end monitoring across early warning, incident response and post-event traceability; its grid-forming capability provides inertia response and short-duration power support. For standalone and grid-side projects, the full range supports modular expansion and rapid response to dispatch instructions, improving regional grid flexibility and balancing capability.

Customised BESS configurations based on required capacity, storage duration and grid-connection conditions.
Fast active and reactive power response enables energy shifting, frequency regulation, voltage support and capacity support.
Supports integration with a broad range of PCS and EMS solutions to meet regional grid codes and interconnection requirements, with proven grid-forming PCS options available.
SunTera provides short-duration power support of up to 3x for 10 seconds. Combined with proven grid-forming PCS solutions from selected partners, it delivers voltage and frequency support, synthetic inertia and short-duration power support, strengthening system stability in weak grids and networks with high renewable penetration.
