Direct peers

• RAFAKO S.A. Polish EPC and boiler manufacturer headquartered in Racibórz; directly competes with ZRE in power plant boiler construction, modernization, and service work for Polish utilities (notably Tauron, PGE). Listed as both a customer reference and adjacent competitor in the boiler/power plant equipment space.
• Polimex-Mostostal S.A. Major Polish EPC general contractor executing power, industrial, and infrastructure projects; comparable to ZRE in power plant construction and mechanical assembly scope, and competes on the same utility tenders in Poland.
• Bilfinger SE: European industrial services provider with extensive power plant maintenance, retrofit, and shutdown/turnaround operations in Germany, Poland and Central Europe; directly comparable in thermal power O&M, boiler/turbine services, and heavy steel/mechanical work.
• Sulzer AG: Swiss-headquartered turbomachinery and pump services company providing overhaul, modernization, and spare parts for steam and gas turbines — directly comparable to ZRE's Gas and Steam Turbine Services division in scope and customer base.

Broad incumbents

• MAN Energy Solutions: Global OEM and service provider for large-bore engines, turbines and power plant components with extensive aftermarket service; competes with ZRE on turbine overhaul and modernization projects across European utilities.
