• Naftogaz group is one of the largest producers and consumers of energy resources in Ukraine. Therefore, sustainable use of fuel and energy and energy efficiency are top priority for the company.

    Naftogaz main goals in energy efficiency

    ENERGY EFFICIENCY POLICY

    Naftogaz has been actively implementing policies on sustainable use of fuel and energy, energy efficiency and alternative energy sources.

    The priorities of the company include the following:

    • energy efficiency evaluation across Ukraine"s oil and gas facilities (energy audit);
    upgrading or replacing the existing obsolete energy equipment;

    • replacing natural gas with electricity to run Ukraine"s gas transmission system;

    • implementing projects to use thermal energy generated by turbine drives of the compressor units;

    • implementing projects to use energy of excess gas pressure;

    • developing geothermal energy using the company's wells;

    • implementing gas replacement projects wherever this is feasible and technically possible;

    • implementing energy management system according to ISO 50001 requirements.

     

     ENERGY EFFICIENCY PROGRAM OF THE COMPANY

    To achieve the energy efficiency objectives, the company designs (annual) and long-term programs incorporating energy efficiency measures. The enterprises of the company run under the Energy Efficiency Improvement Program for 2015-2020, which aims to improve energy efficiency of technological processes in production, storage, transmission and distribution of natural gas and oil across production facilities of Naftogaz. The company wants to reduce energy consumption by approximately 20% compared to the baseline year of 2014 through its Energy Efficiency Program. It is planned to save 892.9 thousand tons of reference fuel (625.03 thousand tons of oil equivalent) in the period from 2015 to 2020, including:

    • Natural gas — 718.18 million cubic meters;

    • Electric power — 88.61 million kWh;

    • Thermal energy — 168.90 thousand Gcal.

    The Energy Efficiency Program is carried out by the company"s energy efficiency department created in 2014.

     

    ENERGY EFFICIENCY POLICY IMPLEMENTATION IN 2015

    Naftogaz has developed and is implementing its Energy Efficiency program for 2015-2020.

    The most outstanding energy efficiency activities in 2015 were:

    • introducing technology to repair defective sections without withdrawing gas from the pipeline;

    • decrerasing gas losses through better sealing of the equipment;

    • offtaking gas out of pipeliene sections before maintenance operations;

    • using recycled gas turbine exhaust heat for heating instead of a boiler;

    • building compressor stations able to collect low-pressure gas;

    • upgrading anodic earthing of the cathodic pipeline protection installations;

    • energy efficient illumination of production facilities and offices;

    • implementing frequency control devices and soft-start induction motors.

    In 2005, the company studied the possibility to use oil and gas wells to produce geothermal energy for heating and electricity. Two pilot geothermal stations with the direct use of heat are to be constructed based on the study results. In 2015, Naftogaz collected data and made a preliminary analysis of the existing facilities (wells that are about to be shut). At the initial stage, the analysis covered 1000 wells, and all facilities with formation temperature over 85°С (minimum technical requirement) were registered.

    At the beginning of 2015, the company took part in TAIEX workshop on deep-earth geothermal energy for the purpose to acquire and study best practices of countries with the developed geothermal sector.

    The company cooperates closely with the Italian Institute for Foreign Trade (Trading Exchange Section of the Embassy of Italy) to get expert assistance in implementing geothermal energy projects with the use of oil-and-gas wells.

    Further implementation of the pilot projects will require a feasibility study for project design and budgeting.

    Resources saved

    PLANS FOR 2016:

    • More active implementation of the Energy Efficiency Program.

    • Improvements to the existing energy management practices based on the international ISO 50000 standards.

    • Kick-start to the modernization project for individual heating and water boiling equipment through energy service agreements with consumers.
