About the company
Przedsiębiorstwo Inżynieryjne „Energy” provides design and construction services for power infrastructure — MV and LV networks and installations, and transformer substations. We combine design work with on-site delivery, which allows us to run a project from documentation through to commissioning. We operate in Poland and abroad.
The company has been operating since 2013.

Equipment and resources
We operate our own machinery and transport fleet — from mini-excavators and a tracked excavator, through thrust-boring equipment, electrofusion welders and generators, to a cable winch, a cable drum trailer, a VLF tester for voltage testing, and scissor and articulating lifts. Owning our equipment means we do not wait on subcontractors or rental availability.
