Battery Energy Storage Solutions (BESS)

Storage for a successful Energy Transition and stable Electricity Grids

Battery storage systems are true all-rounders when it comes to grid stability

Storage Solutions for Energy Transition

Renewable energy’s market share is growing fast worldwide, with the goal of outgrowing fossil fuels and embracing CO2-neutral energy supplies. In the EU alone, renewables are expected to generate 42.5% of all energy by 2030. Energy storage enables all this green electricity to be used efficiently, ensuring electricity grids remain stable.

Battery storage technology is versatile and powerful. Large-scale stationary storage systems ensure sufficient renewable energies are always available at the right time.

Placing BESS strategically across the power grid helps reduce the need for grid expansion by making better use of existing infrastructure. 

Battery storage, coupled with or without renewables, creates flexibility and supply security both at affordable cost for society.

Our Mission 

BayWa r.e. works to ensure no wind or solar facility has to be temporarily shut down. We develop stationary large-scale storage systems, either coupled with wind and PV or as standalone storage. This ensures all green electricity can find its way to the grid. 

Alongside renewables, electricity from wind and solar parks is stored during phases of oversupply and made available when needed. Standalone storage is used to maintain grid stability, delivering power in peak times and for trading on wholesale markets.

We’re a proud a member of the European Association for Storage of Energy (EASE). That sees us actively involved in shaping European storage regulations and modifying energy markets.

The association plays a leading role in integrating energy storage systems into Europe’s energy supply.

How does storage work?

In order to maintain the grid frequency of 50 Hz, there must always be a balance between generation and demand in an electrical system. As soon as one or the other predominates, deviations from the target frequency would occur. To prevent this happening, there is what is known as frequency control power, which is used when generation and consumption are not in balance. BESS can provide these so-called ancillary services for frequency control quickly and cost-effectively, thereby ensuring security of supply.

Transformers

Transformers increase the output voltage of the BESS inverters to the level of the grid voltage.

Substation

Electrical substation serves as a gateway to connect to the national energy market.

Inverters

Convert the DC current from the batteries to the AC current of the national energy market.

Batteries

Batteries are grouped and housed adjacent to inverters.

Cables

Underground cables connect all the components.

Renewable Generation

Battery projects can be either stand-alone projects or may be connected with renewable generation sources. Battery energy storage systems (BESS) enable more renewable energy to be fed into the grid. BESS can reduce feed-in and demand peaks and thus have a dampening effect on energy prices on the electricity exchange as well as reducing the load on the grid.

Site Storage

If required, spare parts are stored in containers or appropriate buildings, protected and in accordance with the manufacturer's specifications.

Lithium-Ion Batteries

The heart of the project, housed in containers to easily wire them together and protect from the weather. The containers are equipped with a so-called HVAC (Heat Ventilation and Air Conditioning unit) to keep them at the perfect temperature in winter and summer. All of the BESS we install are also equipped with a variety of safety devices, including several layers of fire detection and fire protection equipment, as well as leakage, gas and temperature sensors. DC Disconnect Switch allows system to be disconnected remotely or manually when needed. BESS Controller controls charging and discharging of batteries of the batteries fully automatically based on the technical parameters and market signals.

Frequently asked questions about battery energy storage solutions

  • What are the benefits of partnering with BayWa r.e.?

    Decades of experience in renewable energy gives us extensive know-how and a worldwide professional network. We’re a quality-oriented full-service provider with a solid financial background. Our expert teams around the world have extensive knowledge of regional and local conditions. From project design to completion, we remain your trusted partner throughout the entire lifespan of a large-scale storage system. 

  • How important are storage projects for the success of the energy transition?

    Very! Large-scale BESS reduce need for expensive grid expansions. By combining high efficiency and fast reactivity, they balance short-term differences between supply and demand. They also enable renewables to be integrated into the electricity grids more reliably and widely. In future, we’ll see a diversified landscape of storage solutions used to enable the move to net zero. 

  • Why is the flexibility of storage solutions so important?

    The production of solar and wind energy varies depending on the weather. As renewables’ share of overall energy mix increases, grids must compensate, ensuring stable supply even at peak times. Storage solutions offer crucial flexibility: they store power in times of low demand, releasing it again when demand is high. 

  • In which countries does BayWa r.e. implement large-scale storage facilities?

    BayWa r.e. is active in more than 30 countries, and involved in energy storage projects all over the world. Project development and implementation are already well-established in Europe, Asia, and the USA. Since we work on specific projects at different stages of development, it’s important we understand each individual market. That lets us ensure the best possible returns for BESS projects. 

  • Which technologies does BayWa r.e. use for large-scale battery storage?

    As storage devices, lithium-ion (li-ion) batteries have a high energy density and lose little capacity with frequent charging. About 90% of stored energy is recovered and used again. Li-ion batteries are scalable; systems can be of any size, thanks to a modular design. They’re also more widely available, therefore more cost-efficient. 

    Our development teams are always exploring new technologies. We’re in close contact with manufacturers to diversify our technology portfolio. Sodium-ion batteries, for example, have potential to compete with li-ion. Realising this potential represents a big step forward, making batteries less resource-intensive and with more localised value chains.
