TLS Energy's BESS Successfully Passes Qualified Tests for Ancillary Services in Sweden

TLS Energy is proud to announce the successful completion of a major Battery Energy Storage System (BESS) project in Sweden. The client is a giant energy provider in Sweden. The client has expressed satisfaction with the outcome, as the BESS has met all performance expectations. The fact that the tests were completed according to Swedish standards acknowledges that the system functions as intended, reinforcing its reliability and efficiency in real-world applications.

## Ensuring Grid Stability with BESS
Battery Energy Storage Systems (BESS) play a vital role in stabilizing modern power grids, ensuring frequency regulation, and enhancing grid resilience. In Sweden, where renewable energy integration is a key focus, energy storage solutions like TLS Energy’s BESS help balance supply and demand efficiently. 

The successful testing process confirms that TLS Energy’s BESS is fully equipped to provide essential ancillary services, supporting a stable and reliable electricity transmission system. 

## Key Testing Milestones
The client has completed and submitted the testing results to Swedish authority Svenska Kraftnät (SvK) for upcoming ancillary services. Svenska Kraftnät is responsible for ensuring that Sweden’s electricity transmission system remains safe, environmentally sound, and cost-effective—both today and in the future.

The major milestones achieved during the testing phase include:

- **Fast Frequency Reserve (FFR) Tests** – Successfully completed and submitted on January 31, 2025. This service ensures immediate grid stabilization during frequency deviations.
- **Frequency Containment Reserve – Normal (FCR-N) and Frequency Containment Reserve – Disturbance (FCR-D) Tests** – Completed and submitted on February 11, 2025. These services help maintain frequency balance by responding to power fluctuations in real time.
- **Manual Frequency Restoration Reserve (mFRR) Tests** – Successfully concluded and submitted on February 28, 2025. This function allows for manual interventions in frequency restoration, ensuring long-term grid stability.

These achievements highlight TLS Energy’s commitment to adhering to international standards and delivering cutting-edge energy storage solutions that strengthen grid reliability.

## Advancing Renewable Energy Integration
As Sweden continues to expand its renewable energy infrastructure, the need for advanced energy storage solutions has never been more critical. TLS Energy’s BESS is designed to optimize energy utilization by storing surplus power and deploying it when needed, reducing reliance on fossil fuels. Passing these qualified tests affirms that our BESS solutions meet the highest industry standards, reinforcing TLS Energy’s position as a trusted partner in the global energy transition.

With safety as our top priority, TLS Energy utilizes LFP (Lithium Iron Phosphate) battery technology, ensuring superior performance, longevity, and environmental sustainability. Our advanced monitoring and control systems enable seamless integration of renewables into the grid, maximizing efficiency and stability.

## Future Prospects
Following the successful completion of this project and qualified tests, TLS Energy is now well-positioned to expand its energy storage solutions across Sweden and beyond. Our mission is to continue pioneering innovations in BESS technology, providing scalable and flexible solutions that support the clean energy transition.
