Distribution of electrical energy in Slovenia

In Slovenia, electrical energy is distributed by five companies: Elektro Celje, Elektro Gorenjska, Elektro Ljubljana, Elektro Maribor and Elektro Primorska. These will all be re-organised into joint-stock companies in 1998, with the majority of the shares being held by the state and others by employees and various funds. These public companies supply electrical energy to more than 850,000 customers - that is, to all households and the entire industrial sector, with the exception of the five largest industrial buyers in the country. Public companies buy electrical energy from ELES, which is the only company authorised to purchase and transfer electrical energy from the producers, and to import and export electrical energy.

The electricity distribution system is entirely owned by the five public companies, and includes:

• 90 distribution transformer stations (110/x kV);
• 55,300 km of high-, medium- and low-tension wires;
• 12,650 transformer stations.

The total amount of electrical energy sold in 1996 was 7,276 MWh.

The electricity supply system is working with a high degree of operational readiness; in recent years, this been effectively supported by a computerised management system. More than 10% of the total of 3,675 employees have completed college or university education, thus ensuring the up-to-date knowledge and technological development of distribution activities. As a public commercial service, the distribution companies are devoting their full attention to a high level of communication with the buyers of electrical energy.

ELEKTRO CELJE

Elektro Celje is one of the five distribution companies in Slovenia, and has its head office in the town of Celje. The company supplies electrical energy to 149,000 customers, covering an area of 4,345 km2 containing 383,000 inhabitants (approx. 22% of Slovenia’s total). This supply region is divided into three territorial regions covered by individual operation units employing 749 workers. These units are located in Celje, Krsko and Slovenj Gradec.

The development of Elektro Celje dates back to 1913 when, with the founding of the City of Celje Power Station, the first commercial organisation to supply electrical energy to consumers was established in the immediate vicinity of the city. The annual sale of electrical energy amounts to 1,400,000 MWh (270 MW at peak hours). The electricity distribution system consists of 17 distribution transformer stations (110/20 (10) kV), 2,650 transformer stations, 99 km of 110kV high-tension wires, and 13,945 km of medium- and low-tension wires.

A high degree of operational readiness, the rationalisation of electricity consumption, and attention to ecological demands in completing and maintaining the distribution network are, and will remain, the basic aims of the development of Elektro Celje.

ELEKTRO GORENJSKA

Elektro Gorenjska provides a regular supply of electrical energy to 78,012 consumers scattered over an area of 2,091 km2. It supplies 767,569,950 kWh of electrical energy to its users annually with the aid of 15 distribution transformer stations, 1,276 transformer stations and 4,342 km of high- and low-tension wires. It manages 15 power plants with an installed power of 9.4 MW, annually producing 47,317,000 kWh of electrical energy and thus satisfying 5.7% of the overall demand for electrical energy in the Upper Carniola region.

A total of 87.7% of the energy delivered is bought from ELES, while the difference of approx. 6.6% is covered by purchases from private producers. The company employs 395 people and is divided into three operation units and the administration office.

The continuous increase in the consumption of electrical energy demands constant investment in installations, both in terms of capital expenditure and maintenance. In the past five years more than SIT 5 billion, according to 1996 rates, have been invested in installations.

Elektro Gorenjska was one of the first distributors to realise the importance of investment in the remote control of the installations. A remote control system for the Naklo distribution transformer station (35/10 kV ) was put in place as early as 1968, and in 1980 all distribution transformer stations operated through remote control from the distribution control centre.

In the years to come Elektro Gorenjska will lay emphasis chiefly on the following fields of activity: the regulation of internal economic relations in the electrical industry and adaptation to the European market, the further rationalisation of business, the better transfer of information to consumers in order to enable the most rational consumption of energy possible, the modernisation of the information system, the reduction of losses through reconstruction and new construction, and improvements to the reliability of operations by complementing the electricity distribution system and the related instruments for remote control and protection.

ELEKTRO LJUBLJANA

Elektro Ljubljana is the largest distributor of electrical energy in Slovenia, supplying electricity to more than 285,000 customers in an area covering one third of the country. In addition to the distribution of electrical energy, which is its main activity, the company also carries out the entire planning and construction of the medium- and low-voltage electrical supply system. Marking the hundredth anniversary of its foundation in 1997, Elektro Ljubljana re-organised its ownership structure and became a joint-stock company. It remains chiefly in state hands.

Its 1,050 employees attend to the regular operation, maintenance and renovation of the 110/35-10 kV and 35/20-10 kV electricity distribution system, consisting of 26 distribution transformer stations (110/10/20 kV), almost 4,000 high-/medium-tension and medium-/low-tension transformer stations, and 14,200 km of high-, medium- and low-tension wires. Elektro Ljubljana purchases most of the 2,800,000 MWh of electrical energy it sells from ELES, which is the only company for the transfer of electrical energy in our country; however, it also produces a small part of the energy in its own 10 small hydro-electric power stations, as well as buying a further small part from the owners of small private hydro-electric power stations.

In recent years Elektro Ljubljana has paid a great deal of attention to improving relations with the buyers of electrical energy, and the improvement of poor tension conditions in individual regions, and is also actively engaged in providing advice on rational energy consumption. In the construction of the electricity distribution system, Elektro Ljubljana takes into account demands for the best possible ecological solutions. The most important investment made by this public company in the year to come will be the construction of a modern distribution control centre, a new tone-signal command system, and improvements in tension conditions.

ELEKTRO MARIBOR

Historical sources maintain that the first electric lamp was lit in 1884 in Maribor; this represents, we believe, the beginning of the use of electrical energy for commercial purposes in Slovenia. The company itself has undergone several different organisational transformations. Most of these occurred after the Second World War, when its organisation changed in many ways. The company is currently re-organising its ownership structure and will operate as a joint-stock company from 1998, remaining mostly in state hands.

The company employs 934 workers. After re-organisation it will be a joint-stock company with the following share structure: 90.5% held by the state, 1.21% by the Pension and Disability Insurance Capital Fund, 6.31% by the Fund for Development, 0.94% by the Slovenian Indemnity Fund, and 0.96% by the employees.

The company supplies energy to 188,572 customers in north-eastern Slovenia: 171,483 household users, 15,548 small business users, and 1,541 larger industrial users.

There are 934 workers employed in Elektro Maribor: of these, 50 (5.3%) have higher education qualifications, 70 (7.4%) have a college diploma, 683 (73%) have a secondary school certificate, and 132 (14.1%) have basic professional qualifications.

Elektro Maribor is the second largest electricity distribution company in Slovenia. Its electricity distribution system consists of 22 distribution transformer stations (110/x), 20 distribution stations, 14,641 km of high-, medium- and low-tension wires, and 2,850 transformer stations.

ELEKTRO PRIMORSKA

Elektro Primorska, a public company for the distribution of electrical energy, will operate as a joint-stock company from 1998. It is also preparing an application for the ISO 9001 Quality Certificate.

Electrification was introduced to the coastal region very early on, as soon as electrical energy began to be incorporated into the daily lives of people across the planet. The famous tourist town of Postojna acquired its first electric lighting on 5 May 1884 for the illumination of the Postojna Caves. The first power plant in Idrija was built in 1893, with a capacity of 25 KW.

Our 547 workers ensure the continuous supply of high-quality electrical energy to more than 111,000 customers. The electricity distribution system consists of 10 distribution transformer stations (110/x kV), 8,157 km of high-, medium- and low-tension wires, and 1,900 medium-/low-tension transformer stations.

Elektro Primorska has made major investments in the modernisation of its operations. The most important of these include new technology, combined measuring transformers, tariff cut-outs, the gradual transition to remote control and the automatisation of the medium- and high-tension electrical supply system from the DCV (distribution control centre), semi-insulated conductors, the best possible approach to the environment, a range of inventive solutions, and an integrated information system.

Our company’s vision is as follows: the high-quality and steady supply of electrical energy with simultaneous reductions in operating costs; employee satisfaction; friendly and approachable customer care; and the introduction of the most up-to-date, environment-friendly technologies.
