Hufvudstaden

Hufvudstaden uses new technology to resolve the power limitation

In 2019, a renovation project was launched for the office and retail property Skären 9, which is situated in Bibliotekstan in Stockholm. The project has been characterised by a strong focus on sustainability, with the aim of achieving environmental certification. New, more efficient heating and ventilation systems have been installed, as well as 64.6 kW solar cells on the roof. The project did, however, encounter some challenges, as limitations were discovered in power and electricity supply. By thinking in outside the box and using Ferroamp’s technology, Hufvudstaden was able to resolve the issue of power without increasing the load on the grid.

Head of Sustainability Karl-Johan Wall explains that the prevailing power shortage is greatest in the vicinity of big cities, but that the central areas of larger cities are also hard hit.

“The rebuilding project was about to be stopped due to the lack of power. One of Hufvudstaden’s smart electrical technicians had heard about the Swedish company Ferroamp, which had developed a technology to better manage and optimise the use of electricity and output in properties, and we decided to invest,” says Karl-Johan Wall.

The lack of power is clearly evident and resulted in the cost of grid connections, fuse subscriptions and subscriptions for electricity consumed to rise sharply in recent years. All indications are that these costs will continue to increase, which means that more property owners will be seeing more controllable and flexible electricity consumption as being increasingly important. This adds even more value to an investment in EnergyHub technology.

Like many other property companies, Hufvudstaden is naturally reluctant to place a burden on the grid over and above what is sustainable. The electricity supply that the electricity company can provide to the property on Norrlandsgatan is limited, and it is important to bear this in mind.

The investment in energy storage from Ferroamp was based on the need to be able to control power peaks and other loads, so that the power consumption from the property never exceeds the grid connection you had before the conversion. In addition to discharging below power peaks, EnergyHub sends information to charging boxes and controllable loads, to guarantee optimal and cost-efficient electricity consumption.

With its unique technology, Ferroamp enables all property owners who either want to save expensive power consumption or limit power consumption – similar to the scenario for the Hufvudstaden property in question – to adopt an important position.

“If more property owners were to follow Hufvudstaden’s initiative and make active, responsible decisions about energy and power consumption in their properties and choose how they want to affect the load on the grid, multiple goals can be met at the same time – energy strategy, economic and environmental,” believes Mats Karlström, Senior Business Developer at Ferroamp.

By controlling the grid connection with batteries and smart technology, capacity can be freed up in the local grid in Stockholm. More property owners need to make a proactive choice, just like Hufvudstaden has done, and the technology does exist!
