30 MW battery system shipped to Stella Futura’s customers
Stella Futura's containers, 30 MW in total, have been shipped to three of Stella Futura's customer sites in Sweden as part of the Battery-as-a-service offering. Using Stella Futura's skilled engineering staff, the utility of the battery systems are optimized during the long BaaS-contract period.

Over the past year, Stella Futura's engineers have worked closely with their engineering colleagues at battery supplier Tesvolt to ensure that the container systems delivered to Stella Futura's customer sites have the right design and configuration for optimal operation. The systems are adapted to the services included in Stella Futura's Battery-as-a-service offering.
"In addition to the financial aspects behind our battery systems, we highly value our engineers' deep technical knowledge. If you do not have an experienced and knowledgeable engineering team, there will be challenges in everything from the development of the sites and installation, to the operation over the long contract periods we normally have in the Battery-as-a-service setup. You also need to have an in-depth understanding of the hardware to be able to build the logic around long-term and smart financing," says Ulrika Tornerefelt, CEO and founder of Stella Futura.
Understanding the hardware in stationary battery storage is crucial to optimising the utility of battery systems for several reasons:
Performance optimization - Understanding how the function of the battery storage system affects energy transfer can optimise the efficiency of the system. Furthermore, insight into the capabilities and limitations of the hardware can help fine-tune operating parameters to maximise the performance and lifespan of the battery system. This can involve optimising charging and discharging rates, monitoring temperature and voltage, as well as avoiding overloading or deep discharge.
Optimizing financial return - Understanding how hardware components impact the performance and lifespan of the full battery system can optimise the financial return. This means balancing investment costs with operating and maintenance costs, as well as maximising revenues from energy storage services such as frequency control and peak load management.
Safety aspects - Understanding the battery hardware is necessary to ensure that the system operates safely and that the risk of accidents such as thermal runaway and fire is minimised. This includes creating safety redundancy with added protective features, working closely with local rescue services, and closely following safety regulations and installation instructions to minimise the risks of injury to people, loss of property, and impact on nature.
