Power consumption
Electricity savings is one of the most important ecology-related priorities of the Group. We are aware of not only the negative impact that wasted electrical energy has on natural environment but we also see the actual financial benefits which can be achieved thanks to a thrifty power consumption policy.Therefore, we make all efforts to ensure that our network is rolled-out in the most ecological way possible.

Optimization of energy consumption by base transceiver stations | Continuation
Optimization of energy consumption by Base Transceiver Stations not only reduces the negative impact on the environment, but also reduces the network maintenance costs.
Polkomtel’s initiatives which have been undertaken to increase the network’s energy efficiency include:
- refarming of 900 MHz band,
- refarming of 2100 MHz band,
- replacement of air conditioning units to AAA+ class equipment,
- modernization of power systems supporting the telecommunication equipment,
- installation of software with energy-saving features.
We use latest technological solutions for network upgrade and roll-out – high performance rectifiers in our power systems or installation of free-cooling systems in base stations – not only make our network more advanced but also reduce power consumption and emission of CO2.
Thanks to a special software with energy saving feature (for 2G and 4G networks) we are able to flexibly adjust to traffic levels, while switching off redundant capacity and reducing the output power. The test which we conducted together with one of our vendors (Ericsson) on a limited number of sites, equipped with smart meters, enabled us to precisely determine the impact of the energy saving feature. According to these estimations, the total annual savings achieved by using these features exceed 5.5 million kWh, while simultaneously reducing CO2 emission by 4.2 kilotons.
We also do not disregard any seemingly minor efforts, such as for example leaving computers in stand-by mode – taking into account the size of our organization and the number of people working for us, such efforts translate to actual reduction of the adverse impact on natural environmental. An example of this can be the policy introduced in Cyfrowy Polsat which assumes switching off the light when leaving a room, disconnecting chargers once device charging is completed, rational use of water as well as prudent use of air-conditioning.

Eco rules for employees | Continuation
On the occasion of the International Earth Day (April 22th) we regularly refresh – as part of our internal communication – the 10 eco-rules which we have defined together with the employees of Cyfrowy Polsat. Through educational articles published in the Intranet (Cyfrowy Polsat Intranet and Planeta Plusa) we try to encourage people to get actively involved in various activities supporting protection of the environment.
Polkomtel has implemented ecological solutions in, among others, its continuously growing IT systems. State-of-the-art data storage solutions present in Plus network’s server rooms allow the company to achieve tangible power consumption savings. In addition LED-type lighting has for many years been used in Plus network company stores and partner points of sale for illuminating the signs with the company logo. It is also a standard to use power-saving bulbs and automatic light switches. Recently also cars with low CO2 emission have been added to the company’s car fleet.
