Downstream divisionThe key energy efficiency indicator for oil refining enterprises is the energy intensity index (EII) calculated using the methodology of Solomon. This index allows for a quantitative comparison of the energy efficiency of a specific oil refinery with another refinery that is similar in terms of production units and work conditions. The smaller an enterprise’s EII value is, the better its energy efficiency level is.

|Moscow Oil Refinery||124||123||122||114||113|
The specific energy consumption indicator is the most convenient for operational control.

Since 2011, the Downstream Division has employed an Energy Conservation and Energy Efficiency Programme, which is the main tool used to implement the Company’s Energy and Technical Policy in energy efficiency – a strategic priority for the Company’s development – and sets the goals and objectives of the Downstream Division’s enterprises in this area for the medium-term. The programme is drafted by the Downstream Division’s Energy Department for a three-year period with subsequent annual updates.
Under the Programme, the main focuses of the Division’s energy conservation and energy efficiency activities are:
- to improve work efficiency and optimise the processing behaviour of energy and technological equipment,
- to reduce the fuel and energy intensity of technological processes;
- to reduce losses of fuel and energy resources;
- to increase the proportion of steam condensate returned by process units;
- to increase the efficiency of heat exchange processes and the generation and use of thermal energy in core and auxiliary processes;
- to improve the infrastructure level of core and auxiliary production processes at enterprises with metering devices;
- to introduce the energy management system.
The Division’s main energy conservation and energy efficiency measures in the reporting year included:
- replacing and modernising process furnaces to increase their efficiency;
- optimising the recuperation system and using secondary energy resources in technological processes (using heat from product flows to heat raw materials as well as water and heat flows);
- increasing the efficiency of fuel use in process furnaces by utilising modern technologies (ceramic coating of heating surfaces, ultra-thin thermal insulation coating and improved burner devices);
- optimising condensate collection and return systems;
- optimising the operation of compressor equipment;
- increasing the efficiency of heat and steam supply systems;
- modernising lighting systems;
- replacing turbo drives and steam pumps with electric drives.
The Division’s energy conservation activities in 2016 resulted in savings of 2,369.9 TJ of energy and fuel, specifically: 258,700 Gcal of heat energy, 25,000 TOE of fuel and 16.2 million kWh of electricity. Spending on energy resources decreased by RUB 528.9 million. The growth in energy intensity associated with the commissioning of new process units declined by 1.6%, or 7% higher than the 2015 indicators.
In 2016, the Division drafted a Downstream Division Energy Conservation Programme for 2017-2019. It will include two new enterprises: Gazpromneft-Aero and Gazpromneft – Bitumen Materials starting in 2017. The projected economic effect from the programme’s implementation is RUB 1.784 billion.

Gazprom Neft in 2016 also updated a comprehensive programme to improve the reliability of power supplies to oil refining enterprises in 2017-2019. The programme is the main tool for implementing the Downstream Division’s Technical Policy in the reliability of power supplies and specifies the mechanisms for establishing, monitoring, achieving and updating the goals and objectives of the Division’s oil refining enterprises in this regard.
A total of 63 measures with investment of RUB 667 million were implemented in 2016. The main areas of activities included: eliminating power equipment failure, increasing the stability of power supply systems, improving the technical infrastructure level as well as the training and advanced training of personnel.
As a result of the programme’s implementation, positive trends were seen in target performance indicators versus the 2015 levels:
- the total number of failures decreased by 15%;
- the total number of technology downtime hours due to power supply disruptions decreased by 49%;
- the overall level of resistance to external power supply disruptions increased by 30%.
Downstream Division specialists actively work to exchange experience within the Company and with other enterprises in the industry in order to improve the effectiveness of energy efficiency and energy conservation work. Gazprom Neft has created the ‘Power’ Centre of Excellence, which includes the ‘Energy Efficiency’ networking group in which Company specialists identify and exchange best practices in this area.
The work performed by the ‘Power’ Centre of Excellence during the reporting year resulted in an economic effect of RUB 330 million due to the implementation of best practices proposed by experts from the Centre.
The energy conservation programme and the ‘Energy Efficiency’ networking group within the ‘Power’ Centre of Excellence are effective tools that enable the Division to systematically improve its performance in this area. In 2017, we plan to develop interaction with domestic and foreign oil refining companies in order to exchange and replicate advanced expertise and best practices in energy conservation, which will help us to achieve even greater success in this regard.Vladimir Andreyev Head of the Energy Department of the Gazprom Neft Downstream Division
In 2016, representatives of Gazprom Neft and Lukoil held a joint meeting as part of the ‘Power’ Centre of Excellence attended by specialists from the energy divisions of the companies’ corporate centres, electrical supervisor staffs and Lukoil specialised scientific and technical centre as well as energy managers from the ten largest oil refineries in the industry.
