Improving energy efficiency

Energy consumption

In 2015 our total energy consumption for mobile and fixed operations was 286.35 GWh, 1.75% lower than in 2014 (291.39 GWh) due to the fact that we have managed to reduce electricity consumption for mobile network and data centers and the fleet fuel consumption.

Improving energy efficiency represents one of our major sustainability objectives as it contributes both to reduction of our own environmental impact but also contributes to general social effort to reduce environmental footprint and fight climate change. For both our fixed and mobile operations we have developed energy efficiency plans which are reported yearly to ANRE (National Regulatory Authority for Energy). Our energy efficiency management approach is based on:

  • Long term goals towards 2020;
  • Midterm goals covering a period of 2 years;
  • Yearly operational efficiency measures.

Through our energy efficiency and conservation programmes we managed to achieve energy savings of 5.93 GWh, out of which, 4.25 GWh of electricity and 1.67 GWh of district heating and fuel
consumption. The most relevant measures we took in 2015 were:

  • Modernization of electricity network;
  • Increase control and management of temperatures in the equipment rooms of BTS (base transceiver stations);
  • Replacement of old equipment and air conditioning systems.


In 2015, our total electricity consumption (mobile + fixed operations) was of 215.08 GWh, 1.7% lower compared with 2014 (218.89 GWh). Our mobile and fixed networks accounts for almost 90% of our total electricity consumption representing our main focus within the modernization process.

In 2014 and 2015 we have restructured and consolidated our commercial spaces, reducing their numbers and improving space usage efficiency in the existing ones, which lead to a direct reduction of electricity consumption of more than 10%. We continued the upgrade process of the mobile telecommunication network and the implementation of saving energy solutions and we managed to reduce the electricity consumption by almost 10% compared with 2014. Nevertheless, we expect an increase for 2016 as we are continuing to expand our coverage

District heating and fossil fuel consumption

We are using district heating energy and natural gas for heating purposes in our buildings and shops, especially for our fixed operation locations. We have installed electricity backup generators using diesel on all our technical locations to ensure non-interrupted service provision and technical systems integrity. Our improvement options are limited by old heating infrastructure but also by limited control of heating generation and distribution. District heating is used only on our fixed operations facilities and compared with 2014, the consumption increased slightly with 2%.

Compared with 2014, we have managed to reduce the consumption of diesel associated with backup electricity generators in our buildings and base stations with 19.3%, leading also to a reduction of our direct CO2 emissions. Partially this aspect has been influenced by a reduced number of interruptions of electricity supply from the national grid, leading to a reduced need of generators.

Fleet fuel consumption

Our car fleet consists of service vehicles used for all technical operations and commercial vehicles used by our sales team. In 2015 our fuel consumption decreased with almost 9% compared to 2014 based mainly on fleet restructuration both in term of number of cars, which decreased, and vehicle types. The average fuel consumption per kilometer within the fleet decreased also with 5.2%, from 0.071l/km in 2014 to 0.067 l/km in 2015.
