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)

 

52#c940

(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 1,483.551,488.621,709.621,829.24
52#c942

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.

 

52#c943

(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. Physical values correlation:

1 kWh = 3.6 • 106 J; 1 cal =4.1868 J.

Natural gas calorific value is 8,085 kcal per m3.

(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.

GRI 201-2GRI 102-15

The Gazprom Group identified the potential climate change risks and their impact upon the Group’s operations. The key climate change risks of the Gazprom Group are temperature change risks, as well as physical, economic and social risks.

52#c973
The key climate change and GHG risks for the Gazprom Group
Temperature change risks
  • Change of temperature of the most sensitive frozen soils with higher salt content.
  • Increased number and magnitude of adverse hydrometeorological phenomena, including higher frequency of floods during spring and spring/summer tide periods.
  • Shorter periods of winter roads(1) operation.
  • Risks of higher gas consumption for internal operating needs as the outside air temperature declines(2)
Physical risks
  • Risks of damage of buildings and constructions.
  • Risks of higher failure rate of pipeline transport.
  • Risks of deformation of water supply and sewerage systems.
Social risks
  • Risks of higher adverse impact upon people’s health due to extreme and adverse hydrometeorological phenomena and infectious diseases proliferation.
  • Risks of inflicting damage to private property of the employees of the Gazprom Group’s companies.
Environmental risks
  • Risks of environmental damage
Reputational risks
  • Risks of failure to discharge commitments by the Gazprom Group
(1) Winter road means motor road that could be operated in winter period only.

(2) Decline in outside air temperature by 1 degree Celsius.

The Gazprom Group’s companies implement comprehensive activities aimed at mitigating negative consequences of climate change for operational activities. Such activities include:

  • Assessment of the climate change impact in the territories where the Group technological facilities are located;
  • Regular machinery and equipment monitoring, as well as assessment of predictability of the operational processes applied in the areas subject to climate change;
  • Use of reinforced pipes in the areas subject to climate change;
  • Construction of indoor compressor shops in the areas of adverse weather and climate conditions;
  • Construction of backup power plants in the permafrost areas at gas production sites;
  • Development of gas production facilities designs taking into account the weather and climate conditions;
  • Bottom penetration of the pipelines in the areas adjacent to the shores in order to ensure protection of their offshore sections;
  • Permafrost management in the construction areas in course of Yamal peninsula deposits development: redundancy of groundworks and foundations of the facilities reliability using modern thermal stabilization technologies in eternally frozen grounds adjusted for perennial thawing;
  • Development of the comprehensive insurance systems, including insurance of the environmental risks of the Group’s companies and compensation of environmental damage.
