An energy-efficient housing company

Asunto Oy Kauniaisten Herttua is a housing company located in Kauniainen, Finland. From the start, the housing company has invested in smart energy solutions, installing 31 kWp of solar panels and ensuring all 35 parking spaces are prepared for EV charging.

Savings and energy security with batteries

The decision to acquire a battery energy storage system was driven by a desire to optimize the use of existing solar panels. The need to ensure critical functions remain operational during power outages also played a key role. With automatic backup power from the battery system, elevators and lighting continue to function even during outages.

"Of course, a key factor in the decision was whether the system would be financially beneficial. That was a big criterion for the housing company.", mentions Onni Rautanen, Chairman of the Board.

Solution

The housing company has been very satisfied with the smooth installation process and the customer service from Cactos.

"Cactos provided us with an almost turn-key solution. They also took care of coordinating the work required by other partners.", says Rautanen.

The board of the housing company has also been impressed by the Cactos Spine app, which allows them to monitor the system’s performance and profitability in real time.

Results

The battery energy storage system has helped Kauniaisten Herttua maximize the benefits of its locally generated solar energy. Furthermore, the housing company now keeps essential systems running during blackouts. The board has also received positive feedback from residents.

"The original goal—that the battery system produces more than it takes—has also been achieved.", smiles Rautanen.

Most out of self-generated energy

By storing solar power, the housing company can use it later during high-cost hours.

Lower power peaks during peak demand

By drawing power from the battery during peak times, less power is needed from the grid.

Backup power for outages

The housing company keeps critical functions such as elevators running during power cuts.
