Gazprom Neft works hard to promote energy efficiency. The Company’s divisions are developing and implementing measures to reduce energy consumption, and introducing energy efficiency plans.
An active energy-saving policy is a strategic priority for the EPS. As part of medium-term energy efficiency plans, energy-saving measures are intended to reduce the energy-related component of the overall unit production costs incurred by EPS facilities.
The main indicator of energy efficiency — the specific energy consumption (SEC) for the extraction of liquid — declined by 1.3% (from 25.02 to 24.70 kWh/t) at Gazpromneft-Noyabrskneftegaz in 2012, by 1.9% (from 43.7 to 42.88 kWh/t) at Gazpromneft-Khantos, and by 2.6% (from 34.46 to 33.58 kWh/t) at Gazpromneft-East compared with 2011. In 2012, measures were introduced to reduce energy consumption; these saved 145 million kWh at EPS facilities, including those at Gazpromneft-Noyabrskneftegaz — 39 million kWh, Gazpromneft-Muravlenko — 76 million kWh, Gazpromneft-Khantos — 23 million kWh, and Gazpromneft-East — 6 million kWh.
Currently, the Company’s EPS facilities are focusing on establishing a regular, permanent system of energy saving — an energy management system that complies with the ISO 50001:2011 standard. The energy management system is based on the introduction of technical and system measures and mechanisms for monitoring, auditing, analyzing and taking corrective actions. This will enable a shift from individual technical measures to systemic solutions both in technology and management.
To reduce emergency power curtailments and subsequent oil losses, the Company has developed a program to improve reliability and upgrade equipment and grids at Gazprom Neft production subsidiaries and affiliates for 2013 to 2015. In addition to technical measures, the program will include research on the current reliability of grids and electrical equipment, ranking and assessing damage risks, including those resulting from excessive climatic loads
The main areas of the program are:
- measures to strengthen the protection of grids and power engineering facilities from thunderstorms and lightning;
- measures to upgrade grids and substations, by retrofitting electrical installations;
- power grid and equipment overhauls;
- re-engineering of power facilities.
In 2012, in accordance with the requirements of Federal Law No. 261, energy audits were conducted at all subsidiaries and affiliates of EPS. Based on the audit results, a set of energy-saving measures has been developed, along with the receipt of energy certificates. The measures are scheduled for implementation in 2013 and 2014.
The energy efficiency plan for Gazprom Neft’s logistics, refinement and sales segment for 2013 to 2015 aims to reduce the consumption of heat and electricity by 9,926.3 TJ (including at the Omsk refinery — 6,440.3 TJ, Moscow refinery — 992.1 TJ and YaNOS — 2,493.9 TJ), which make up almost 5% of the planned consumption of electricity and heat during this period.
In 2012, the LRSS-oriented corporate project ‘Enhancing the Efficiency of Energy-Saving Process Management at Oil Refining Facilities of OJSC Gazprom Neft (the energy management system — EMS)’ was launched as per the ISO 50001 standard. A unified methodological framework for implementing the energy management system at Gazprom Neft’s oil refineries was developed, including the ‘Energy Efficiency Technical Policy’, the basic standard for the ‘LRSS-Oriented Energy Management System’, methodological documents on drafting the ‘Program for Energy Saving and Enhanced Energy Efficiency’ and monitoring the impact of implementing energy-saving measures. In 2013, the Company plans to introduce the energy management system at pilot facilities — OJSC Gazpromneft-Omsk Refinery.
MAIN ENERGY-SAVING INITIATIVES AT LRSS SUBSIDIARIES AND AFFILIATES:
- introducing variable-frequency drives in electric motors (Omsk refinery, Moscow refinery, YaNOS);
- modernizing compressor equipment: implementing step control, installing an anti-surge system; reconstructing instrumentationand controls for the air drying system (Omsk refinery);
- reconstructing lighting systems using energy-saving technologies (Moscow refinery, Omsk refinery, YaNOS);
- increasing in-house steam production through waste heat recovery from process furnaces and streams (YaNOS, Omsk refinery);
- enhancing fuel efficiency in process furnaces: ceramic heating surfaces; hyperfine thermal insulation of furnaces; burner modernization, replacing tent stoves (with an efficiency coefficient of 63% to 70%) with vertical cylindrical furnaces (with an efficiency coefficient of 90%) at the Omsk refinery, Moscow refinery, and YaNOS.
In 2012, as a result of energy efficiency measures in the logistics, refinement and sales segment, the Company saved 3,141.2 TJ of heat and electricity, reducing energy costs by more than RUB 1.3 billion.
Major energy-saving measures in 2012:
- reconstruction of economizers and superheaters for recovery boilers (with an energy-saving impact of 546.6 TJ);
- installation of digital excitation controllers at compressor motors (with an energy-saving impact of 100.1 TJ)
- hyperfine thermal insulation of furnaces (with an energy-saving impact of 151.7 TJ).
Gazprom Neft is exploring new possibilities for using alternative energy sources. At year-end 2012, the Serbian company, NIS, in which Gazprom Neft has a 56.5% interest, signed an agreement to construct a wind farm at Plandiste with Energowind. NIS has a 50% share of the project; the total cost of the wind farm, including development of the basic design and obtaining required permits, is EUR 160 million. Construction is scheduled to commence in the summer of 2013. The project will include the installation of 34 wind turbines with a total capacity of 102 MW in the Plandiste municipality. The wind farm at Plandiste will be the first wind farm in Serbia and will produce 212 GWh of electricity per year.
