● Background:
Sweden is striving to achieve a 100% fossil-free energy system, driven by policy initiatives that promote renewable energy and storage technologies. Energy storage is essential for supporting the intermittent nature of renewable sources like wind and solar. As a regulatory tool, energy storage enhances grid flexibility and plays a crucial role in the ancillary services market, particularly for frequency regulation and peak shaving.
● Challenge:
In the remote Arctic region of Sweden, where harsh climate conditions prevail, reliable energy storage is vital to ensure the continuous supply of clean energy. The area experiences distinct winter and summer seasons, with temperatures dropping as low as -30℃ during the winter months. The challenge was to develop an energy storage solution that could withstand these extreme conditions and operate efficiently off-grid while meeting local energy needs year-round.
● Solution:
POWEROAD provided an advanced off-grid energy storage solution utilizing its FLEX 215 Air Cooling Outdoor Cabinet ESS with a capacity of 187.5 kW / 430 kWh, integrated with the SINEXECEL power conversion system (PCS). This independent storage solution was specifically designed to handle the cold Arctic environment, maintaining stable and efficient operation in temperatures as low as -30℃. The system ensures the stability of energy supply, providing uninterrupted clean energy to the region throughout the year.
● Highlights:
– High-Standard Design: POWEROAD’s ESS is engineered to withstand extreme cold, maintaining operational efficiency even in temperatures as low as -30℃. This resilience ensures reliable energy supply despite harsh weather conditions.
– Economic Returns: The ESS generates revenue by participating in local power system services such as peak shaving, frequency regulation, and demand management. These services offer continuously growing economic returns for customers by optimizing energy management.
– Pre-Commissioning and Pre-Assembly: The system was pre-commissioned and pre-assembled, enabling rapid delivery and reducing the project cycle. This streamlined approach ensures quick deployment, even in challenging environments.
This off-grid energy storage system provides the Arctic region with a stable and uninterrupted clean energy supply, supporting Sweden’s ambitious goal of a 100% fossil-free energy system. The POWEROAD ESS enhances local grid flexibility and ensures that renewable energy sources are used effectively, despite the intermittent nature of solar and wind power. The solution also generates long-term economic returns through participation in ancillary services, making it both a sustainable and profitable investment for the region.
POWEROAD’s innovative energy storage solution in Sweden’s Arctic region demonstrates the potential of advanced storage technologies to operate reliably in extreme climates while supporting the country’s transition to a fully renewable energy grid. This project underscores the importance of flexible, efficient, and durable energy storage solutions in achieving sustainability goals.
