Improving energy efficiency is one of the UN’s Sustainable Development Goals to 2030. Efficient utilisation of energy resources makes it possible to improve performance, optimise production processes, and reduce environmental impact.
An energy management system which is compliant with the ISO 50001:2011 standard has been put in place and is functioning successfully at the Gazprom Neft Corporate Centre, and at 14Gazpromneft Yamal, Messoyakhaneftegaz, Gazpromneft-Noyabrskneftegaz, Gazpromneft-Khantos, Gazpromneft-Vostok, Gazprom Neft Orenburg, Slavneft-Megionneftegaz, the Gazprom Neft Omsk Refinery, the Gazprom Neft Moscow Refinery, NIS, Slavneft-YANOS, the Gazpromneft Moscow Lubricants Plant, the Gazprom Neft Ryazan Bitumen Binders Plant, and the Gazpromneft Omsk Lubricants Plant. major subsidiaries and upstream and downstream joint ventures.
Every year Gazprom Neft PJSC develops and approves a development plan for its energy management system. This plan includes expanding the scope of the energy management system, adopting new regulatory documents and updating outdated ones, providing personnel training, and adopting a new version of the ISO 50001:2018 standard.
In order to improve its management of energy conservation, Gazprom Neft focuses on the following areas:
- developing and certifying the energy management system to meet the international ISO 50001:2018 standard;
- personnel training in energy management and energy efficiency;
- improving the company’s regulatory framework in relation to energy conservation and energy efficiency;
- testing and implementing new energy-conservation technologies;
- implementing digitalisation projects;
- sharing experience with other industry players.
In 2019, the company’s energy efficiency and energy conservation initiatives were focused on improving the performance of power-generation and process equipment, and optimising the utilisation of energy resources and process conditions.
The Upstream Division saves a significant amount of energy resources by using technical measures, such as replacing centrifugal pumps, using brushless DC electric motors, switching to short-term or intermittent operation of wells, performing geological and engineering operations to reduce the amount of water produced and reinjected into strata, and introducing energy-efficient pumping equipment. Key organisational measures adopted include energy audits, an energy-efficiency monitoring system, optimising the cost of electricity from external networks, and replacing diesel power plants with gas-turbine power plants. The company has also introduced a number of IT projects relating to energy conservation and energy efficiency.
Key energy-efficiency activities in the Downstream Division include upgrading process furnaces to improve their performance; optimising a recovery system and using secondary energy resources in production processes; using fuel more efficiently in furnaces; optimising steam-condensation systems; optimising the operation of compressor equipment; improving the performance of heat-supply systems; upgrading lighting systems and using electric pumps instead of steam pumps.
Gazprom Neft promotes the generation of renewable energy. The company recognises how important it is to transform global energy systems to reduce CO2 emissions.
In 2019, the Omsk Refinery completed the first phase of the construction of a 1 MW solar-power plant. This new power plant covers an area of 2.5 hectares and comprises 2,500 solar panels, produced by Russia’s solar-power company, Hevel. This investment project to introduce green-energy technologies, which is unique in Russian industry, forms part of the major Omsk Refinery development programme.
The pilot power station supplies electricity to all administrative buildings at the Omsk Refinery, including a residential complex for 2,600 employees. Based on research results and measurements at the power plant, Gazprom Neft will make a decision about constructing a 20 MW solar-power plant at the Omsk Refinery in 2021.
NIS alternative energy projects
The geology of the Pannonian Basin means that Serbia is one of the countries in continental Europe which has great geothermal energy potential.
NIS, the Gazprom Neft subsidiary in Serbia, has over 60 geothermal wells which can be used for generating electricity and heat. NIS is now operating four wells that provide third-party commercial projects with heat and hot water. Gazprom Neft continued to develop geothermal generation in Serbia in 2019:
- a general geothermal-potential map was created based on existing information on operating temperatures of wells;
- a preliminary assessment of the potential for creating commercial cases for power-generation was carried out;
- ranges of temperatures and inflow required to set up a profitable business were determined.
Cooperating with partners, NIS continues construction of the Plandiste wind farm, involving the installation of 34 wind turbines, with a total capacity of 102 MW and expected annual electricity output of 212 GWh. This wind farm will reduce CO2 emissions by 332,000 tonnes per year.
