In 2018, the total fuel consumption for internal operating needs by PJSC Gazprom’s natural gas production, transportation, underground storage and processing subsidiaries was 65,034.8 thousand tons of reference fuel(1)
(1) Cooling/heating and steam generation are non-core businesses for PJSC Gazprom natural gas production, transportation, underground storage and processing subsidiaries, therefore, accounting of energy consumption for those processes could not be arranged for those PJSC subsidiaries.
|Total fuel and energy resources||1,483.55||1,488.62||1,709.62||1,829.24|
The increase in the consumption of energy resources was driven by production volumes growth; however, a comparison of the unit consumption indicators of fuel and energy resources against commodities transportation in similar conditions shows that the energy intensity of PJSC Gazprom’s key production activities has decreased.
The total electric power consumption by PJSC Gazprom natural gas production, transportation, underground storage and processing subsidiaries was:
- in 2015 — 10,415.72 million kWh;
- in 2016 — 10,688.2 million kWh;
- in 2017 — 12,496.9 million kWh;
- in 2018 — 12,958.0 million kWh(1).
Sales of fuel and energy resources (electric power, fuel for heating/cooling purposes, steam sold) are not a core business for natural gas production, transportation, underground storage and processing subsidiaries, therefore accounting of fuel and energy sales volumes could not be arranged for those subsidiaries of PJSC Gazprom.
(1) In order to monitor efficiency of fuel and energy resources consumption for internal operating needs by natural gas production, transportation, underground storage and processing subsidiaries, PJSC Gazprom uses corporate reporting forms on fuel and energy resources consumption for internal operating needs for the corresponding activities approved by the order of PJSC Gazprom.

At Gazprom Neftekhim Salavat LLC, there is no energy consumption from renewable sources.
In 2018, energy intensity of the core PJSC Gazprom activities increased due to the growth of production volumes. However, a comparison of the unit consumption indicators of fuel and energy resources against commodities transportation in similar conditions shows that the energy intensity of PJSC Gazprom’s key production activities has decreased.

(1) In order to calculate the energy intensity ratio for the main type of PJSC Gazprom activities, the following denominators were used:
• Gas production — volume of gas produced (thousand m3);
• Gas transportation — commodity transportation activities (million m3 • km);
• Underground gas storage — the total volume of gas taken and injected (thousand m3);
• Gas processing — the respective processed volumes of gas and liquid hydrocarbon feedstock (thousand m3).
In the course of energy intensity calculation, the following fuel and energy resources consumed for internal operating needs of the core PJSC Gazprom production processes were taken into account: natural gas, electric power, heat energy.
In course of energy intensity calculation, the energy consumed internally by PJSC Gazprom is taken into account.

(1) Energy intensity of Gazprom Energoholding companies is defined as the ratio of fuel consumption at power plants and boiler houses of the subsidiaries, heat energy supplied to the subsidiaries’ networks by third parties, electric power consumed at boiler houses and heat networks facilities of the subsidiaries to the total busbar output of the power plants and heat energy to end customers (all intragroup balances of heat energy are excluded).
HPP energy intensity is defined as the ratio of electric power generated increased by the average efficiency ratio of hydroturbine units (assumed at 0.9) to HPP busbar output.
The general energy intensity takes into account HPP electric power output at 0.9 efficiency ratio in the numerator and HPP busbar output in the denominator.
