About Us

MVM OVIT Zrt., as a member of the MVM Group, is the electric power network constructing and implementing company of Hungary with the widest scope of activities. It has performed for six decades the construction, maintenance and improvement of high-voltage transmission lines and transformer stations. The activities of the company possessing great traditions are basically linked up with the Hungarian transmission network and the national power plants, along with this it undertakes regularly construction, maintenance, reconstruction and development tasks for the railway companies, the power suppliers and power network companies, major industrial consumers and foreign clients as well.


The company philosophy of MVM OVIT Zrt. is to be a reliable, competitive, high-standard contributor with its intellectual and material resources in the long run to the national and the international energy market.


The company was founded in March of 1949 as a state enterprise. Its primordial task was to reconstruct and repair the Hungarian network damaged or destroyed after World War II, then later to extend, maintain and operate the network. This period saw the beginning of increasing on a large scale the power plant capacities and network connections, as well as of elaborating the network installation technologies and widening the degree of mechanisation. The several years’ process of uniting the domestic electric power network started from 1952, and as from 1953 we commenced building the 220 kV voltage level transmission lines. The 400 kV voltage level appeared in Hungary in the 60 s and in the 70 s the company faced a task which was counted as a rarity all over the world at that time: establishing a 750 kV interconnection of a very great transmission capacity between Hungary and the Soviet Union (today Ukraine).

It was with great professional preparedness at all times that MVM OVIT Zrt. established the new technologies, procured the most up-to-date devices, applied the series of tools and small machines of own development and production, while acquired an international professional recognition which has had a marked influence on the judgement of the company even today.

On 31 December 1991 the former state enterprise was transformed, the National Power Line Company came into being as a general legal successor. The company retained to the full extent the scope of activities of the enterprise, but the role of constructing, maintaining and operating its own network was substituted by a contracting activity concluded with the new owners of the networks.

The necessary organisational change ensured the adaptation of the company to the changed external circumstances, helping the development of a market sensitive behaviour and working method, thanks to which it has obtained a dominant (market leading) role in the entire spectrum of the electric energy industry.

In the 21st century the first significant transformation in the organisation and operation of the company occurred on 1 January 2006, when some 500 persons of the Operations Management was transferred to the MAVIR ZRt. (MAVIR Hungarian Independent Transmission Operator Company Ltd.) In spite of this great change, the company was able to become even stronger, and preserved — and in certain areas highly expanded — its presence on the market and was able to recover the lost sales revenue of the operation activity. As a ceaseless continuation of this activity, the company competed for and won the operation of the equipment serving for the electric power supply of Mol Nyrt. Danube Refinery.

The Company opened up new profiles in the areas of nuclear power plant, telecommunication and big industrial consumers, recruiting a crew of professionals with special experience, qualifications, formerly working for other specialized companies. In totality this meant 200 new entrants from the staff of the Paks Nuclear Power Plant Zrt., ATOMIX Kft., MVM Zrt., Mol Nyrt. and Schneider Electric Zrt. Recognising the market demand, exploiting and developing further the existing resources the Steel Work Business Management started — along with the smooth supply of the national demands — the production of industrial steel work of several thousand tons for the European market, and as from September of 2006 the scope of activities of the Business Management was enlarged also with the integration of the tasks of the machining plant of Paks.

The change started at the company in the previous years arrived at a new milestone on 1 January 2008. The number of the three managements existing until that time was increased by the addition of a new one, the Maintenance Directorate, which became the organisation of the company carrying out power plant maintenance, project implementation and service provision activities. Its task is executing the maintenance, reconstruction, construction and other service provision works, with high priority in the power plants of the MVM Group.

The changes of the organisational structures effected on 1 January 2010 (see in the enclosure at the back) were made in accordance with the purposes, challenges and expectations outlined in the long-term plans of the company. The Power Transmission Network Directorate and the Production Directorate came into being by the separation of the former Technical Directorate.

The Power Transmission Network Directorate performs the construction, maintenance and operation tasks of the basic network — and of the professional field attached to this. The Production Directorate established on the base of the former Corrosion Protection, Steel Work and Machine Repair Business Management includes the Transportation Plant and the Steel Work Business Management. Since the market headway of this latter business branch has accelerated in the recent years, its development has become of highlighted importance, the mapping of this is the creation of new organisational units better adapting to the manufacturing processes and attending to them. Accommodating to the management reorganisation and in order to strengthen the project approach, the organisation of the Business Directorate has also undergone a transformation. The name of the Maintenance Directorate has changed to Power Plant and Maintenance Directorate, better reflecting

its present and future tasks.

In 2010 the company adopted a new, medium-term strategy, specifying in it as one of the new objectives an active participation in railway development. Parallel with improving its railway construction machinery pool, and with a futher education of its network-installer specialists, the Company won its first assignments in 2011 for the modernisation of the railway overhead lines (for railway electrification). Thus the company, supported by its experience of more than 25 years in the field of establishing of motive-power substations, is able to provide complex services in the area of railway development.

On 1 March 2011, the Business Management of Power Equipment Machinery was established, while the Power Equipment Machinery Plant started its operations on the facility base of the factory being formerly owned by Transelektro Ganz-Röck, by manufacturing power-plant and industrial boilers, and individual machineries and devices.

On 18 April 2012, the Company’s official name was changed in accordance with the resolution of its General Assembly, to MVM OVIT Országos Villamostávvezeték Zrt. (MVM OVIT National Power Line Company Ltd.).

MVM OVIT Zrt. has been undertaking projects in foreign markets with increasing frequency in recent years. In 2012, the company participated in transmission line projects in Scotland and Germany, and they have been performing network renovation tasks in the Czech Republic since 2013. In 2012–13, MVM OVIT Zrt. completed the modernisation project of the protection and control technology system of the 66 kV electrical network of CERN in Switzerland. In 2014, the company won a tender by the Jordanian electricity company for the construction of two 400 kV, 185 km long electrical transmission lines. In October 2015, the company concluded an agreement about the establishment of a joint venture in Saudi Arabia, in order to allow them to enter the country’s electricity industry market as a general contractor in order to bid for high-voltage network construction jobs.
