Solar and wind energy storage systems
Better use of renewable energy through energy storage.
Energy storage systems stabilise green power supplies
Globally, the market share of renewable energy is growing rapidly, with the ultimate aim of reducing fossil fuel consumption and ensuring a CO2-neutral energy supply. In the EU alone, renewable energy is expected to account for 42.5% of all energy generated by 2030. Energy storage enables the efficient use of green electricity, ensuring the stability of electricity grids. With the increasing share of renewables in the Polish electricity system, it is also necessary to increase the potential for energy storage.
BayWa r.e. is internationally active in the development and implementation of wind, solar, and energy storage projects. Our experience and technical expertise give us a comprehensive understanding of local requirements for battery energy storage systems (BESS), both as stand-alone projects and in combination with PV or wind farms.
What are battery energy storage systems (BESS)?
The success of the energy transition depends on the use of smart combinations of sustainable technologies. Rechargeable (battery) energy storage systems are one such solution that allow us to take full advantage of renewable energy sources.
The technology used in energy storage is versatile and efficient. Large-scale stationary storage systems ensure that an adequate amount of renewable energy is always available at the right time. The strategic deployment of BESS across the power grid reduces the need for grid expansion by making better use of existing infrastructure.
Energy storage, via standalone batteries or in combination with renewable energy sources, provides flexibility and security of electricity supply.
How does energy storage work?
BESS are rechargeable batteries that allow energy from different sources, mainly renewable like solar and wind, to be stored and then released when the national grid requires power.

The expertise of BayWa r.e. covers the entire value chain: from planning and financing to implementation, safe operation, and sales.
BESS help to accelerate the energy transition while ensuring long-term, stable cash flows.
Our many years of experience in the field of wind energy and PV projects enable us to implement renewables projects in the most profitable way possible. BayWa r.e. experts take care of the entire investment process, from construction to energy sales. If you have already invested in renewable energy sources, BESS will further diversify your portfolio and generate additional revenue streams.
