Zaporizhstal invests UAH 75 million in modernization of power equipment at CHPP

Overhauls of boilers, turbines and generators will ensure the reliability of the plant's power system

The Zaporizhstal Iron and Steel Works, part of the Metinvest Group, has begun a series of major repairs to key energy equipment at its combined heat and power plant (CHP). According to the capital investment program for 2025, the company will allocate approximately UAH 75 million for modernization. This was reported in a press release from the company.

«The thermal power plant is responsible for the production of three key types of energy resources – steam, blast air, and electricity – and supplies them to the company’s divisions, ensuring the continuity of the production process at the sintering plant, blast furnace, rolling and other main and auxiliary shops. The major repairs will increase the reliability and fault tolerance of both individual units and the entire Zaporizhstal energy complex,» said Taras Shevchenko, acting CEO of Zaporizhstal.

The work is being carried out in stages while production continues, which allows the planned production volumes to be maintained. Boiler unit No. 5 was the first to undergo repairs, with the large-scale renovation taking about 100 days. The main tasks are to replace the steam superheater, economizer, pipelines, fans, automation, and electrical equipment.

Next will be turbine compressor unit No. 7, whose repair will take 80 days. It is planned to replace the compressor wheels, steam valves, atmospheric valve, sensors, and electric drives of the pumps.

In the fall, a major overhaul of turbine generator No. 1 will begin, scheduled to last 45 days. Engineers will modernize the control systems, replace the control valve assemblies, and perform maintenance on the generator rotor and stator.

The repair work is being carried out by Zaporizhstal’s own engineering service with the involvement of specialized contractors – Inventum Ukraine and Intel Energo.

As a reminder, at the end of 2024, Zaporizhstal increased its production of commercial rolled metal by 18.3% compared to 2023, to 2.43 million tons. Pig iron production amounted to 3.11 million tons (+14.3% y/y), steel production – 2.89 million tons (+17.2% y/y).

The increase in production volumes in 2024 compared to 2023 is due to higher blast furnace productivity, increased demand for commercial pig iron, and the partial restoration of the maritime export route.

As part of the 2024 investment program, the company allocated UAH 938 million to support production capacities. In particular, funds were invested in the overhaul of key production units and the implementation of investment projects in occupational safety, information technology, and the social sphere. In 2025, investments are planned to increase to UAH 1.1 billion.
