In southern Sweden, Vattenfall, a state-owned energy company, is building two battery storage systems that will be an efficient combination of wind power and batteries. The two battery storage facilities are expected to be ready for operation in early 2024.
In 2023, a battery facility for energy storage will be connected to Höge väg and Hjuleberg wind farms in the south of Sweden. The batteries are housed in a total of 102 battery modules with 29 energy storage capacities of MWh for Höge väg and 35 MWh for Hjuleberg.
Vattenfall has been running the two wind farms with the company Skandia for the past ten years. The company has also operated large battery storage systems in combination with wind and solar power parks at several European locations. The two battery projects that are currently being installed will be the largest in the country. The goal is to maximize the use of renewable energy and essentially balance and contribute to frequency stability in the Swedish electricity grid.
– We believe hybrid parks will become increasingly important for Vattenfall’s business models based on renewables. On the one hand, the operation becomes more economical because production, storage and grid connection take place within the same infrastructure, on the other hand, hybrid plants can provide additional income for wind power operators while at the same time contributing to more stable grids, says Johan Kronman, project manager for the battery projects.
Both facilities are planned to be installed in the spring of 2024. Vattenfall is investigating the possibility of installing more battery storage systems at other production sites in Sweden where several technologies can be combined in a single hybrid park.
