Battery energy storage systems

Flexible, scalable design for efficient energy storage.

Energy storage is critical to decarbonizing the power system and reducing greenhouse gas emissions. It's also essential to build resilient, reliable, and affordable electricity grids that can handle the variable nature of renewable energy sources like wind and solar.

Battery Energy Storage Systems, or BESS, are rechargeable batteries that can store energy from different sources and discharge it when needed. BESS consist of one or more batteries and can be used to balance the electric grid, provide backup power and improve grid stability.

Stay ahead with Siemens Energy long-term, flexible and sustainable Qstor™ innovations based on proven power electronics to shape future grids.

Qstor™ is Siemens Energy's end-to-end solution for BESS, including Plant Controls, Enclosure (Core), Battery Management System, Digital Solutions and Services. From renewable energy producers, conventional thermal power plant operators and grid operators to industrial electricity consumers, and offshore drilling platforms or vessels, Qstor offers highly efficient and cost-effective energy storage solutions.
With Qstor, you can even generate new revenue streams as it allows energy arbitrage or directly reduce your electricity bill via peak shaving.
