Powerhouse Brattørkaia Trondheim – Norway

Implementation of a 1716kWh / 250kW battery energy storage system, including engineering, renewable energy integration, installation, and commissioning

Powerhouse Brattørkaia, located in Trondheim, Norway, is a cutting-edge building that

sets new standards in sustainable architecture. The building's innovative design, featuring solar panels on both its roof and facade, allows it to generate more energy than it consumes. This makes Powerhouse Brattørkaia a global leader in green innovation, providing an exemplary model of energy-positive buildings.

About the Powerhouse

Powerhouse Brattørkaia is a state-of-the-art Zero Energy Plus building designed with sustainability in mind. It is equipped with a total of 3,000 square meters of solar panels that cover its roof and facade. These panels generate approximately 485,000kWh of electricity annually.

After 60 years the building will offset the total energy used for its construction, production of materials, day-to-day running and eventual demolition. The Powerhouse relies on the grid in winter but compensates by generating far more energy than it consumes in summer, which is largely distributed to other buildings in the neighborhood. The building has received the certification "Outstanding" from BREEAM, a widely recognized standard for environmentally friendly buildings.

In designing this building, every material and technical solution has been carefully chosen to maximize energy efficiency and minimize waste. The building’s location in Trondheim, Norway, where renewable energy is abundant, further enhances its sustainability.

The Challenge

The challenge for Powerhouse Brattørkaia was to create a building that not only consumes less energy but also produces more than it needs, reducing reliance on external energy sources. The key was to harness solar power effectively while managing energy storage and distribution within the building to ensure efficiency throughout the day and night.

Additionally, the building needed a solution that would store excess energy generated during peak sunlight hours for use during periods of lower sunlight or higher demand, ensuring continuous energy availability without relying on the grid. Ekoda’s 1716kWh / 250kW energy storage solution enables the building to enhance its energy independence while further reducing its environmental footprint.

The Solution

Ekoda played a crucial role in the success of Powerhouse Brattørkaia by designing, producing, installing, and commissioning the building’s energy storage system. This system was essential for maximizing the building’s self-sufficiency and ensuring optimal control over its energy flow.

In 2024, Ekoda delivered a 1716kWh / 250kW EkoDynamics energy storage solution. This battery storage system enables the building to store excess solar energy produced throughout the day, reducing energy waste and allowing for better utilization of the building’s solar power generation. By storing energy during the day, the building can meet its energy needs during periods when solar power generation is lower, significantly reducing the building’s reliance on external energy sources.

The Result

The implementation of the energy storage solution significantly improves Powerhouse Brattørkaia’s energy efficiency. The building now produces more energy over its lifetime than is required for its construction, operation, and eventual demolition. This is a key aspect of its design, supporting Norway’s ambition to reduce its carbon footprint and transition to renewable energy.

Thanks to Ekoda’s energy storage system, Powerhouse Brattørkaia can utilize a larger portion of the solar energy it generates, optimizing energy consumption and reducing waste, and we are very proud of our role in the process. The energy storage solution has helped the building become one of the largest newly built energy-plus buildings in Norway. This enhances both self-sufficiency and sustainability.

Conclusion

Powerhouse Brattørkaia is a groundbreaking project that exemplifies the future of

energy-efficient and sustainable buildings. Through the integration of innovative solar power systems and energy storage solutions, the building generates more energy than it consumes, supplying the neighborhood’s buildings with the green surplus energy.

Ekoda is proud to have contributed to this landmark project by providing a high-quality energy storage solution that enhances the building’s overall efficiency. Powerhouse Brattørkaia stands as a global leader in green innovation and energy-positive architecture, setting an important precedent for the future of sustainable construction.
