Induction power supports prestigious powerhouse

Powerhouse Telemark is set to become one of the world's most spectacular and energy efficient buildings. Construction began in September, with a little help from EFD Induction Norway.

“A powerhouse is a building that generates more energy than it uses throughout its lifetime”, explains Sales Manager Terje Solgaard. “Telemark Powerhouse will also set a whole new standard for comfort and function.”

The building is designed by internationally renowned architects Snøhetta, otherwise known for impressive projects such as the library in Alexandria and the 9/11 museum at Ground Zero in New York. It is constructed for optimal production of electricity from solar energy, and large sections of the façade and roof will be covered with solar panels. It will render approximately 239,000 kWh per year, making it a small power plant that will deliver surplus power to the grid.

Powerhouse Telemark – affectionately known as “The Diamond” for its characteristic shape – will have 8358 square meters of luxury spread over 11 floors. The lucky tenants will have access to fancy facilities such as a fitness room, a manned foyer, a restaurant and a very exclusive roof terrace boasting spectacular views of the river.

Centrally located just outside downtown Porsgrunn, residents will have only minutes to stroll into town along the riverside or to one of Norway’s largest industrial parks just across the bridge.

If all goes according to plan, the building will be completed by the summer of 2020. When construction began on site this September, it quickly became clear that ground conditions required extra reinforcement with steel piles. The edges of these piles had to be hardened for them to withstand the enormous strain of being rammed into the ground and the vast weight they will have to carry.

The construction is done by local machining company “Karlsen & Solbakken Maskinering”.

"We know them well. They are actually one of our suppliers”, says Application Lab Supervisor, Karl Biørn.

“They first attempted to harden the edges of the piles with traditional flame heating, but they were unable to generate sufficient energy to achieve the result they required”, says Terje Solgaard. “Then they thought to call us.”

 

HELPERS: Karl Biørn (left) and Terje Solgaard with the Minac and coil that saved the day for a machining company in need.

 

So, Terje and Karl loaded a Minac 18/25 onto a van and went out to see if they could be of assistance.

Obviously, the Minac did the job with no trouble at all.

“With the Minac, we accomplished faster results and better quality”, says Terje. “And, we had consistent results on all the piles.”

 

INDUCTION IN ACTION: The glowing red metal reflecting in the oil bath that is used for cooling. When the heated portion of the pile is lowered into the oil, it becomes hard.

HARDENED: The lower edge of the pile has been hardened to withstand the strain of being hammered into the ground.

THE DIAMOND: Boating tourists headed for the Telemark Canal will be treated to quite the sight on their way up the river. Of course, another few kilometres further upstream, they will go past EFD Induction.
