Battery energy storage

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. There are different energy storage solutions available today, but lithium-ion batteries are currently the technology of choice due to their cost-effectiveness and high efficiency.

What are BESS?

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.

What are the benefits of BESS?

Battery storage systems offer many benefits over traditional grid storage solutions, such as:

From renewable energy producers, conventional thermal power plant operators and grid operators to industrial electricity consumers, and offshore drilling platforms or vessels, BESS offer highly efficient and cost-effective energy storage solutions.

With BESS, you can even generate new revenue streams as it allows energy arbitrage or directly reduce your electricity bill via peak shaving.

Currently, Siemens Energy offers BlueVault™ Storage solution for the marine and offshore market and SIESTART for utilities and T&D network operators. For industrial deployment, we offer a customized battery storage solution to meet your unique business need.

Conventional power generation

As well as providing a sustainable alternative to black start capabilities, BESS also helps you generate additional revenues through energy arbitrage. In addition, it can also reduce your costs by charging or discharging energy at optimal loads.

BlueVault Battery System

Marine & Offshore

BESS ensures continuity of power and minimizes emissions in marine and offshore businesses. 

It also creates new revenue streams by lowering peak levels or stabilizing grids.

Transmission & Distribution

Through frequency responses and ancillary services, BESS stabilize grid conditions and balances loads. By storing energy close to its use, they also reduce grid extension pressure.

BESS with wind and solar parks


By avoiding curtailments and shifting the energy to when it is exactly needed, BESS actively promotes decarbonization. 

BESS for industry parks and industrial applications


With BESS you can enjoy flexible access to power regardless of your location while simultaneously achieving a high level of security of supply. By reducing energy consumption during peak periods (peak shaving), you can also optimize operational costs.

Our team of professionals supports you from the beginning of the project by analyzing your business case, designing, and engineering the systems, and helping you throughout the commercial operations and beyond.
