Commercial Power Engineering - Substations Back

The increasing demand for electricity and the growing need for reliable power supply forces Utility companies to develop new energy facilities. Due to the age of the electrical power equipment operated in Poland, their modernisation or replacement has become the need. In the recent times, we have been observing the increase in such works in our portfolio. Some examples below.
