Multiple benefits for the customer and consumers
The modernization work of the Mediaș power station brings a series of direct and indirect benefits.
End consumers will benefit from better quality services, which will be seen in the reduction of the number of power outages, but also their duration.
The investment also leads to better protection of the environment. Through this modernization, the PCB capacitor coils were eliminated, which can affect the soil and the water table in case of a battery breakage, the appearance of waste that can affect the environment. With the new technologies implemented in the installed equipment, the risk of pollution is very low.
Other benefits of the works within this project obtained by simplifying the single-wire electrical diagram of the station and the integration of new equipment are the increase in the degree of safety in operation and the decrease of maintenance expenses by up to 25%.
