In modern area development and new construction projects, energy storage is increasingly being included as an integral part. A battery with an inverter plays a key role in this. By temporarily storing locally generated solar energy in a new construction battery storage system, the energy self-sufficiency of homes or apartments increases and grid reinforcement in construction projects is avoided. For project developers, this means that with energy storage in development projects they can build faster, meet the requirements of grid operators, and be prepared for peak consumption. A battery storage for project development prevents feedback that leads to bottlenecks in the grid while residents benefit from lower energy costs and higher energy efficiency. Applications such as a central storage for residential areas, collective battery storage or a neighborhood battery in new constructions make it possible to intelligently distribute energy within the project. This works not only in residential construction but also in commercial construction, transformation projects, and business complexes with batteries in commercial construction. By including energy storage as a construction option from the beginning – for example in the specifications, tender document, or as a requirement in the building permit – you increase the sustainability and value of the property. A battery in the technical room or as a standalone storage solution for a new construction project enhances the future-proof character. With battery storage in apartments, battery storage in residential construction or energy storage in tendering, you build more than just bricks: you invest in grid relief in new constructions, control over consumption, and an attractive energy label.
