The TAURON Group as the largest electricity distributor and the second largest electricity seller and producer in Poland is an extremely important element for maintaining Poland’s energy security.

The main task of the energy sector is to ensure regular and reliable energy supply. The importance of a high level of energy security is incontrovertible because the condition of energy industry directly affects the operation of all the branches of industry and the society. It is understandable than that energy problems at the level of the European Union arouse such a great interest and emotions.

The TAURON Group is a greatly important element of Poland’s energy system. [EN-DMA] [G4-4] Most energy in the Group is produced by conventional units – 5 power plants and 3 combined heat and power plants, concentrated in TAURON Wytwarzanie and TAURON Ciepło respectively. In 2016, the capacity of all the units (conventional and renewable) belonging to the TAURON Group was over 6.1 GW, which is similar to the previous year (6.3 GW*).

Conscious and responsible management of the environmental impact and optimization of energy use are among the foundations of the TAURON Group’s activity. Energy demand is restricted by implementing new technological solutions and eliminating energy intensive solutions. An important aspect of energy management is the ongoing monitoring of its use. Any irregularities observed, unusual increases, etc. are immediately analyzed, which makes it possible to respond quickly.

As a result of the actions taken in 2016, the total use of energy from non-renewable sources in companies from the TAURON Group fell by nearly 10% (year on year).

If a company uses more energy for its own needs, this means higher costs. For this reason, companies from the TAURON Group optimize processes to reduce energy-intensity. An important role in improving energy efficiency is played by monitoring electricity use in machines at each stage of its production process. Where the demand for energy is considerably lower than production capacities, power plants use the most technically efficient and economical machines to avoid generating losses.

In 2016, the energy-intensity ratio for the Group’s production companies slightly increased.

[EU-DMA] For several years, TAURON Dystrybucja has consistently invested in modernization and expansion of electricity distribution networks, due to which users will be less frequently exposed to consequences of power failures. The planned investments in the next 10 years in modernization and expansion of the existing grid (without line connections) are for the total amount of PLN 13.5 billion.


Each year we run thousands of projects whose major aim is to improve the security, reliability and quality of electricity supply. [G4-EU4] Every year, TAURON Dystrybucja performs over 60 thousand line connection agreements, actively responding to customers’ investment needs. The construction of new plants or expansion of the grids ensure the highest quality standards of electricity delivered to users sensitive to supply disruptions or customers locating their activity in expanded economic zones.

Large investment projects are in progress in the modernization of medium and low voltage lines and the implementation of solutions such as smart grids. To build and evaluate investment strategies, we use modern IT systems for short- and long-term asset management. Its purpose is to target expenditures so as to have the greatest impact on improving security and the efficiency of electricity supply. At the same time, this contributes to improving the quality of the supplied electricity, also increasing the fail-safety of the grid and development opportunities for the prosumer market.

The recent years are a period of intensive expansion and modernization of distribution infrastructure with construction of modern grid dispatch centers and making the work of crews more efficient. All this is being done to improve the grid’s reliability, enhance the quality parameters of electricity and shorten supply-side interruptions.

Distribution of electricity over great distances is inherently connected with its losses. It is impossible to eradicate losses but as a result of the investments in progress and maintenance, TAURON Dystrybucja constantly improves its efficiency. In 2016, the level of electricity losses (defined as a total of technical and non-technical losses) was lower than in 2015.

Transmission and distribution losses as a percentage of total transmitted/distributed electricity

It is worth noting that non-technical losses, which result, among other things, from errors of measurement systems or incorrect recording of electricity sold, also include illegal use of power from the grid (the so called theft of electricity). To fight this phenomenon, TAURON Dystrybucja, in cooperation with the Police, runs a social campaign called “Put a stop to illegal use of electricity”.

GOOD PRACTICE – Social campaign “Put a stop to illegal use of electricity”


[EU-DMA] The campaign is addressed in particular to the Police, City Guard, property managers and customers of TAURON Dystrybucja and aims to ensure customers’ security and continuity of electricity supplies by fighting its illegal use (IEU). The Energy Inspection Center also got involved in the campaign. In 2016, 5 conferences were held about fighting IEU. At the conferences, 450 police officers, property managers and local government officials were educated about the basics of detecting and counteracting illegal electricity use. In addition, a book was published entitled Teoretyczne i praktyczne aspekty przestrzegania prawa energetycznego. Nielegalny pobór energii i inne nadużycia na rynku energetycznym. [Theoretical and practical aspects of compliance with the Energy Law. Illegal electricity use and other malpractices on the energy market.] The monograph was the result of a conference held at the Jagiellonian University in 2015. 


We strive to be innovative

[EU-DMA] In a long-term perspective, building a competitive advantage in the energy sector is inseparably connected with innovativeness.Research and development plays an important role in shaping the future image of the TAURON Group. Implementation of modern technologies, products and services will be intensified in the entire value chain.

Building an innovative culture in the organization and motivating employees to put forward their ideas is an important element of the Strategy of the TAURON Group for 2016-2025. To achieve this objective, Innovation Zone was created in the Intranet as a bank of innovative ideas of employees.

The most important initiatives and research and development projects conducted in the TAURON Group in 2016


TAURON invests not only in traditional R+D projects but also in startups. One of these projects is participation in the Pilot Maker program. The project leader is techBrainers, and its major partner – TAURON Polska Energia. Two other companies – Kross and Amplus – also take part in the project. Pilot Maker was granted funding of nearly PLN 6 million in the contest held by the Polish Agency for Enterprise Development – Scale UP. The assumption behind the contest was to combine the potential of startups with the experience, infrastructure and resources of large companies.


It is an international research and development program performed as an industrial and scientific consortium and financed from European funds. The full name of the program is “Motivating end-users to change their behavior by involving ICT tools and information services regarding the use of power, internal environment, health and lifestyle”. The ultimate objective of the project is to launch technological solutions to influence positively customers’ behavior by raising their awareness and sense of ownership. The results of the work of industrial partners (including Whirlpool and TAURON) and scientific groups from Holland, Slovenia, Italy and Denmark will be presented all over Europe. In Poland, the project will be implemented within Smart City Wrocław.


TAURON Wydobycie, together with the Central Mining Institute (GIG) in Katowice and five international scientific partners, signed an agreement on joint performance of a research project “Processing post-mining and electronic waste – New resources for a sustainable future” (CEReS). The project aims to reduce environmental threats connected with storage of highly sulphated post-mining waste by preparing innovative technological solutions. A new approach assumes that the waste will serve a cheap source of a solution for leaching valuable metals from PCB electronic waste. Such a process will ensure stabilization of properties of post-mining waste, making it possible to recover base metals from PCB electronic waste, including rare earth elements. The project will use pots-mining waste from the plants of TAURON Wydobycie.


TAURON Dystrybucja and Przedsiębiorstwo Komunikacji Miejskiej [Public Transport Company] in Jaworzno started cooperation on research and development in the area of technology for charging electric buses. During the first stage, plug-in charging infrastructure will be tested. Development of electromobility also requires the development and adaptation of distribution networks; therefore, the study will review the impact of charging on the quality of electricity in the grid and the efficiency of frequently recharged batteries. Next, a pilot station will be launched for charging and quick replacement of batteries for electric buses.
