Utility-scale BESS
Utility-Scale Battery Energy Storage for Grid-Scale Projects in Europe
SAKETE utility-scale BESS uses standardized 5 MWh containers and 10 MWh / 5 MW integrated blocks that scale into 20 MWh AC blocks and 80 MW / 160 MWh grid-connected plants, delivered turnkey with central PCS, medium-voltage step-up and EMS.
SAKETE utility-scale BESS scales from a single 5 MWh container and 10 MWh integrated block up to multi-unit 20 MWh AC blocks and 80 MW / 160 MWh grid-connected plants, delivered turnkey with central PCS and medium-voltage step-up. Optional grid-forming control supports weak-grid and standalone applications.

Product FAQ
How large can a SAKETE utility-scale system be?
Systems scale from a single 5 MWh container and 10 MWh / 5 MW block up to multi-unit 20 MWh AC blocks and 80 MW / 160 MWh grid-connected plants.
Is the PCS and step-up transformer included?
Yes. Utility-scale projects are delivered turnkey with central PCS, prefabricated inverter substations (SKTESS2500K / 5000K / 10000K class) and medium-voltage step-up.
Does it support grid-forming operation?
Grid-forming control is available as an option for weak-grid, standalone and stability-service applications.
Which grid codes are supported?
PCS options are grid-code compliant for European connection, including EN 50549, VDE-AR-N 4105, G99 and IEC 62116 anti-islanding, confirmed per project and country.
