It monitors the energy efficiency of installations and their sub-processes on an ongoing basis. It analyses individual areas and participates in tasks aimed at reducing energy consumption.
LOTOS sets itself ambitious targets — in 2020, it initiated certification of the group energy management system according to ISO 50001. It is also important to obtain white certificates, i.e. energy efficiency certificates issued by the Energy Regulatory Office. The certificates are recorded on the Polish Power Exchange and constitute hard evidence that the concerns is improving its energy management.
The Grupa LOTOS’s energy efficiency improvements translate directly into cleaner air and lower water consumption. The upgrades carried out in previous years (adaptation of EC boilers to be fired with natural gas) resulted in the company emitting very little sulphur or dust into the atmosphere. We are also constantly taking tangible measures to reduce CO2 emissions.
Thanks to operational approach to energy consumption management, the Grupa LOTOS’s refinery is one of the most energy-efficient in ones Europe.
The Grupa LOTOS takes its own measures to improve energy efficiency. In 2020, a special organisational unit — the Energy Efficiency Office — identified and implemented, in cooperation with the production area, 22 production process optimisation measures with a total value of savings exceeding PLN 2.5 million. In addition, the Grupa LOTOS received the first white certificates in 2020 — investment support specified in the Act on energy efficiency. The value of the obtained certificates exceeds PLN 1.1 million. Further applications for support under the Act on energy efficiency are under preparation.
Total energy consumption in the LOTOS Group was amounted to 34,740,518.65 GJ in 2020.

Thanks to the implemented optimisations of the Grupa LOTOS’s refinery installations, it was possible to reduce the energy consumption of almost all energy utilities (reduction calculated in relation to the baseline condition — prior to the optimisation).
Data on energy generation and consumption are reported only at the consolidated level, for the entire LOTOS Group.

The increase in the energy intensity ratio y/y was due, among others, to a change in the configuration of the refinery’s operation — at the end of 2019, the delayed coking unit (DCU) was launched, in the last quarter of 2020, the WOW installation (Hydrogen Recovery Node) was launched; the majority of planned stoppage of many production installations was carried out in the second quarter of 2020 and the operation of refinery installations was adapted to the current demand for products.
