Finland is making significant strides in renewable energy storage with the construction of its largest battery energy storage system (BESS). This project is set to enhance grid stability and support the country’s transition to sustainable energy. Here’s a detailed look at everything you need to know.
What Is Finland’s Huge Battery-Storage Project?
The project, led by French renewable energy company Neoen, involves the construction of a 56.4 MW / 112.9 MWh lithium-ion battery system named Yllikkälä Power Reserve Two (YPR2). It is being developed near Lappeenranta and will be the largest battery energy storage system in the Nordic region upon completion.
Why Is This Project Important?
This large-scale energy storage system plays a crucial role in Finland’s renewable energy ambitions. Key benefits include:
- Grid Stability: The battery will help balance electricity supply and demand, especially during peak hours.
- Renewable Energy Integration: It supports wind and solar energy adoption by storing excess power and releasing it when needed.
- Energy Security: The system reduces reliance on imported energy and enhances Finland’s energy independence.
Who Is Behind the Project?
The project is developed by Neoen, a leading renewable energy company known for large-scale battery storage solutions worldwide. This is not their first battery project in Finland; in 2020, they completed the Yllikkälä Power Reserve One, a 30 MW / 30 MWh facility in the same location.
When Will Construction Be Completed?
Construction of YPR2 began in December 2023, and the battery is expected to be fully operational in the first half of 2025.
How Does the Battery Storage Work?
The system uses lithium-ion battery technology to store energy when electricity supply exceeds demand. When demand rises, the stored energy is discharged back into the grid. This helps stabilize power fluctuations caused by intermittent renewable energy sources like wind and solar.
What Impact Will This Have on Finland’s Energy Market?
- Supports Green Transition: The battery facilitates a greater share of renewable energy in the national grid.
- Enhances Market Efficiency: By balancing energy supply, it helps prevent power shortages and price spikes.
- Encourages Future Investments: The success of this project could attract more investment in energy storage solutions across Finland and Europe.
Are There Other Battery Projects in Finland?
Yes, in addition to Neoen’s project, Nala Renewables has acquired a 50 MW BESS project in Southern Ostrobothnia, scheduled for construction in 2025. Finland is increasingly investing in battery storage to support its carbon neutrality goals by 2035.
Conclusion
Finland’s Yllikkälä Power Reserve Two is a game-changer for the country’s energy sector, bringing stability, sustainability, and security to the grid. As the largest battery storage facility in the Nordics, it is a critical step toward achieving a greener future.
