Battery Energy Storage (BESS)

Europe’s energy mix is shifting rapidly with the share of solar and wind growing. This leads to greater volatility in power prices and more demanding grid operations – especially when strong solar generation pushes prices down in the middle of the day, while afternoons and evenings bring higher demand and higher prices. As a result, the need for flexibility and fast-responding resources that can stabilize the grid is increasing.

Battery Energy Storage Systems (BESS) are grid-connected battery installations that store electricity and deliver it back when it is needed most. In practice, the battery is charged when prices are low or when there is surplus renewable generation, and discharged during peak-demand periods. In addition, BESS can provide ancillary services such as frequency regulation and reserves to keep the system stable around 50 Hz, and can also support functions such as congestion relief, voltage support, and black start.

We develop BESS with the same approach as in real estate—long-term value creation through control of the full value chain and robust project execution. Our strength lies in the combination of regulatory expertise, deep technical know-how, and the ability to drive complex processes from early-stage development through realization. We are building a portfolio of grid-connected battery projects across Europe, typically ranging from tens to several hundred MW per project, where the combination of price volatility, rising renewable penetration, and demand for system services creates attractive demand for flexibility.
