2. 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

4. 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

5. 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

6. 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

7. Energy Savings Potential in Metallurgical Sector in Uzbekistan
In the Metallurgical Sector there are:
520 compressors, installed capacity kW
2599 pumps, installed capacity kW
1561 ventilation units, installed capacity
52110 kW

8. 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

12. 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

13. 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
