Client references — published in full

Why it matters

A reference is a document, not a claim

When distribution system operators and general contractors choose a contractor for power works, they look first at experience on similar jobs. In tenders, reference letters are usually the main evidence that participation conditions are met: they confirm the type of works, their value, the dates and that they were performed properly.

That is why we don't summarise our references or pull quotes out of context. We publish every letter in full (in the original Polish), and on the project pages we spell out its content: cable types and lengths, the number of junctions and accessories, drilling, dismantling. Any client can check for themselves what we built and for whom.

• ZILINSKIS — two contracts: MV line undergrounding in Toruń and feeder lines for RS Maliniec in Konin
• PIWOWARSKI — the Bolewice MV line and a network rebuild across eight villages
