For 30 years, UNIGREG has been providing reliable solutions to its customers. The history of our company dates back to 1995, when Grzegorz Kołdyj started his business, initially focusing on transport services. We quickly expanded our offer to include lighting equipment rental, and in 2000 we purchased the first modern power generator. This enabled us to provide a wider range of services in the area of mass outdoor events, film and advertising production, as well as servicing construction sites, industrial facilities and military training grounds. Today, as a leader in the power generator industry, we offer comprehensive services for the largest events in Poland and abroad, providing our clients with professionalism and full support at every stage of project implementation.
For almost three decades we have actively participated in shaping and developing the generator rental market in Poland. Our presence was essential on stages such as iconic music festivals, including Open’er Festival, Orange Warsaw Festival, Audioriver Festival, as well as during the annual Great Orchestra of Christmas Charity (WOŚP). Our support during prestigious events such as COP24 and the NATO Summit is undeniable proof of our reliability. In addition, we supplied energy during renowned agricultural fairs such as Agro Show. We have become not only a market leader, but also a reliable partner, providing energy for unforgettable moments and events. Our experience and professionalism have made our brand synonymous with reliability and the highest quality in the world of events.
We implement comprehensive event projects, supporting music festivals, technical events, and industrial and military projects.
