FAQ about battery storage systems

Batteries are becoming a core part of how electricity markets function, especially as renewable energy sources like wind and solar become more dominant. By storing excess energy during peak periods and releasing it when demand is high, batteries help maintain a stable and reliable electricity supply for consumers. This will potentially mean lower energy costs as we reduce the need for fossil fuel-based peaking plants.

For energy buyers and grid operators, that is a direct and measurable financial benefit. Batteries can also provide backup during grid disturbances or energy breakdowns, helping keep power stable and communities running.

Battery storage is increasingly becoming a central part of how we design and deliver solar projects, both by retrofitting batteries into existing parks and by integrating them into new projects from the outset. Adding a battery system allows us to store electricity when production is high, release it when demand increases, and reduce curtailment — improving both the flexibility and long-term value of each asset.

Co-location also means shared infrastructure: one grid connection, one plot of land, one set of operational processes. This reduces capital costs and simplifies both development and asset management.

Yes. Battery storage is increasingly becoming a central part of how we design and deliver solar projects, both by retrofitting batteries into existing parks and by integrating them into new projects from the outset.

The types of batteries used in our energy storage systems are thermally and chemically stable and are not rated as a health risk. In addition, they are made from materials such as iron, copper, and graphite, which have a lower environmental impact than other battery technologies.

Battery storage systems generate noise from components such as inverters, switchgear, and cooling fans. When planning battery installations, noise calculations and assessments ensure that the Danish Environmental Protection Agency’s (Miljøstyrelsen) guidelines limit values for noise are met. If necessary, noise reduction measures such as acoustic barriers and building structures around noisy elements are incorporated.

Battery storage systems are designed with multiple safety features to reduce the risk of failure. In the unlikely event of a fire, fire detection and prevention systems are installed in each module to quickly handle and mitigate the incident. The battery storage units are also equipped with gas suppression systems to extinguish fires, ensuring the safety of the facility and surrounding areas. In addition, our battery units are strategically placed with sufficient distance between adjacent battery storage systems. This ensures that an accident can be contained within one area and not spread to other parts of the facility.
