In this period 9 new substantions will be built. Acute problems with the net of the malls and the villa areas

The city growth in the future can be measured not only by the number of its residents or by the surface of the area the city covers itself.  It can be also calculated by the measurement units for power and voltage, because the consumption of electric energy is naturally increasing not only because of the population growth, but because of the city’s constant economy development.

The new GCP of Varna covers the city development until 2030 and the forecasts of some specialists show, that if at present the average annual consumption of electricity is 400 MW, in the period indicated, it will reach 860 MW. In order to ensure additional power and to increase security of the electric power supply of Varna Municipality, the net has to be upgraded at a couple of stages. One of the conditions for the first stage is the reconstruction of the net and the building of a new substantion, - Izgrev (translator’s note -  izgrev means sunrise in English). It will supply electricity to present and future consumers to the north of Christo Smirnenski Boulevard, in city quarters with double habitation and non-permitted electricity supply.

It is planned for two more substantions to be erected, supplied with cable lines for the switching in the city net - ‘Galata’ and ‘Christo Botev’. The latter should provide enough energy for the area of the big commercial and business centres in the West industrial city area.  Besides  the three substantions indicated in the first stage, other two new substantions will be built in the west end of Klisse bair and the airport, and still another couple of substantions in the region of Borovets and Priseltsi, and another one in Konstantinovo, (next to the land of Eurolink Investment Group) to the south. The GCP provides for a new electrical substantion in the central part of the city, which will be close to the Spartacus Stadium. It will cover the ever growing demand while being part of the electric supply scheme of the central part with a double power capacity. As a matter of fact, the authors of the electrical elaboration in the new GCP report the chaos in the electricity distribution net to be the most serious problem of the system. The erection of new electricity distribution stations is in difficulty, in the villa areas in particular. The electric supply in those city quarters is reported as non-permitted. The lack of streets’ regulation makes the construction of whatever cable net, compliant with the normative requirements of the GCP, extremely difficult. The authors of the GCP state in addition that for the needs of the city malls and the business centres, the electric power has been wrongly distributed and long cable lines have been installed chaotically crosswise. This actually means that considerable investments have to be made in the improvement and the proper re-erection of the electrical transfer net. The authors of the elaboration explicitly underline that the process has been declared as a priority of the Municipality as well as of E.ON.

Alternative energy

The use of alternative energy sources and wind power supply in particular represent a peculiar accent in the elaboration of the electrical system in the new GCP. The park of wind generators to the north of the municipality will be added to it by a couple of electricity distribution pillars of the Kavarna substantion. It is needless to say that the problem with the accumulation and the preservation of electrical energy will remain unsolved unless the system of wind collecting energy is not exploited effectively. That is why it is necessary to search for new sources. The solar energy is one of the alternatives to take into consideration. It can be encouraged solely by economic programmes based on scientific elaborations. The holiday complexes are expected to become more economically effective by improving their systems for complex use of energy sources and building betterment. It is important to apply the latter measurement to the old housing fund. The use of geothermal waters and household litters is another alternative for the city of Varna and Varna municipality, for they can be utilized as energy sources as well.

The connection with the region

While considering the electric supply of Varna Municipality, it is also important to take into account the small municipalities (such as Aksakovo and Avren), using joint electricity supply. The Airport substantion will provide for the increased consumption of Aksakovo municipality, while the electricity distribution pillars originating from the Mascuda substantion in direction of the junction station of Klisse bair, should be moved as outlets of the future supply in the region. Bearing in mind the enlargement of the city and the holiday complexes from Byala to Durankulak, the authors of the energy elaboration of the GCP forecast that the consumption in the region will be from 1200 up to 1400 MW. As a consequence, a lot of hard work has to be done for the launch of higher voltage of 400 KV in the region. This will also be the right time to use the opportunity of ecologic electricity from the wind generators in Dobroudja.
