Since the 1980s, the plant has been secured by an analogue camera system from the Czech company STEZ, whose tradition METEL follows. Over the last 10 years, METEL has supplied hundreds of industrial switches and switchboards to this facility.


A power plant consisting of four 440 MW VVER reactors, designed in the 1970s. The reactors are based on Russian technology. Since the 1990s, the plant has been continuously modernised... METEL has supplied approximately 100 customized optical converters to the plant.


Rivne Nuclear Power Plant is a power plant in Varash, Rivne Oblast, Ukraine. The technology monitoring system is a LAN-RING interconnected transmission system.


Approximately 50% of the electricity in the Czech Republic is generated in coal-fired power plants. Most of them are owned by the Czech state-owned company CEZ. Since the 1990s, we have supplied hundreds of twisted pair converters, FO converters and industrial switches.


Mosenergo is a subsidiary of Gazprom and is Russia's largest fossil fuel power company and the largest thermal power company in the world. In addition to electricity, Mosenergo also generates and sells heat. In 2014-2015, METEL supplied more than 50 industrial switches to Mosenergo's facilities.


After 9/11, CEZ Group invested heavily in dam security. It was particularly important to ensure good protection of the cascade of dams on the Vltava River. These dams are located on the river above Prague, so they had to be well protected against attacks. We were involved in all these projects.
In 2022, the modernization of the LAN-RING system started!
