Transformer station Gråberget in Sweden

WT Energiesysteme GmbH Umspannwerk Graberge Schweden

WT Energiesysteme – your partner for the energy transition


WT Energiesysteme GmbH, founded in 2002, can look back on a successful 15-year development:
Over 100 high-voltage substations with more than 6000 MVA installed capacity switched on on schedule.
A remarkable result!


We do not see ourselves as contractors, but as partners.
Starting from the consultation over the complete planning, the construction, the connection to the respective telecontrol system up to the putting into operation – Turnkey and everything from a hand. Partner just.
But that’s not all: WT Energiesysteme always implements its construction projects with local partners.


Founded in 2016 in Luleå as a subsidiary, WT Energisystem AB is building two substations for Europe’s largest onshore wind farm in Markbygden in Norbotten. Of course with our local partners, MDH Bygg AB and Install Piteå AB.


And the development continues: Another milestone in our success story is the realization of the substation Flarken in Norrbotten – client Vattenfall Eldistribution AB. Others will follow.


WT Energy Systems – we would like to be partners for you!
