Prof. Khashimov Aripdjan Adilovich ENERGY AND ENVIRONMENTAL IMPACTS FROM AN EXTENSIVE USE OF VSDs IN UZBEK INDUSTRY By: Prof. Khashimov Aripdjan Adilovich Tashkent State Technical University & Prof. Rampias Ioannis Technological Educational Institute of Athens 2nd International Scientific Conference on “Energy and Climate Change”, 8-9 October 2009

Introduction A new design of controller for asynchronous motor drive systems with prospects for wide use applications in industry has been developed A scenario based approach, based on Industrial tests on the new controllers in various motor-drive systems, was used to for the evaluation of energy savings potential and the avoided CO2 emissions in the Metallurgical Sector in Uzbekistan 2nd International Scientific Conference on “Energy and Climate Change”, 8-9 October 2009

The analysis focuses on two scenarios: Business-As-Usual (BAU) Introduction The analysis focuses on two scenarios: Business-As-Usual (BAU) Moderate 2nd International Scientific Conference on “Energy and Climate Change”, 8-9 October 2009

Illustrative Polices under the Introduction Illustrative Polices under the MODERATE SCENARIO Expand the efficiency standards and implement new efficiency standards for industrial equipment Increase enforcement and adoption of energy saving and environmental protection schemes in industry Expand cost shared government R&D expenditures on energy saving new technologies to increase the penetration of energy efficiency equipment in industry 2nd International Scientific Conference on “Energy and Climate Change”, 8-9 October 2009 4

Energy Savings Potential in Metallurgical Sector in Uzbekistan Both scenarios are based on measurements over a period of five years on selected electric motor- drive systems in the industrial site of the “Uzbek Metallurgical Plant” in Tashkent Province. The selected electric motor-drive systems were the following: a 75 kW compressor unit, a 7.5 kW pump unit, and an 11 kW ventilation unit 2nd International Scientific Conference on “Energy and Climate Change”, 8-9 October 2009 5

Energy Savings Potential in Metallurgical Sector in Uzbekistan The selected electric motor-drive systems have shown annual electricity savings of 19%, 23.5% and 20.5% respectively through the use of controllers 2nd International Scientific Conference on “Energy and Climate Change”, 8-9 October 2009

Energy Savings Potential in Metallurgical Sector in Uzbekistan In the Metallurgical Sector there are: 520 compressors, installed capacity 290811 kW 2599 pumps, installed capacity 227400 kW 1561 ventilation units, installed capacity 52110 kW 2nd International Scientific Conference on “Energy and Climate Change”, 8-9 October 2009

Energy Savings Potential in Metallurgical Sector in Uzbekistan Annual electricity consumption in 2008: 25.13×108 kWh in compressors 19.65×108 kWh in pumps 19.65×108 kWh in ventilation units 2nd International Scientific Conference on “Energy and Climate Change”, 8-9 October 2009

Energy Savings Potential in Metallurgical Sector in Uzbekistan Total annual electricity consumption 2nd International Scientific Conference on “Energy and Climate Change”, 8-9 October 2009

Energy Savings Potential in Metallurgical Sector in Uzbekistan 2nd International Scientific Conference on “Energy and Climate Change”, 8-9 October 2009 10

Energy Savings Potential in Metallurgical Sector in Uzbekistan Cumulative Electricity Savings by the year 2018 Cumulative Avoided CO2 Emissions 3.1 billion kWh 2.1 million metric tons of CO2 2nd International Scientific Conference on “Energy and Climate Change”, 8-9 October 2009

Conclusions The Policies can play an important role in stimulating the development and market penetration of modern controllers in Uzbek industry. The energy efficient technologies could help Uzbekistan meet a wide array of challenges, including reduction in air pollution and improvement in economic competitiveness 2nd International Scientific Conference on “Energy and Climate Change”, 8-9 October 2009

Conclusions (cont.) The technology and policy costs required to implement these technologies would be less than the energy cost savings from the more efficient use of electricity in the Metallurgical sector The technology improvements required are possible, If the Government and private sector invest in the R&D There are uncertainties about the efficacy of policies in the industrial sector-market barriers 2nd International Scientific Conference on “Energy and Climate Change”, 8-9 October 2009
