About reasons for withdrawal of the Republic of Uzbekistan from the Central Asian Unified energy system

26.11.2009

Currently the decision of Uzbekistan to withdraw from the Central Asian Unified energy system is under focus of different foreign mass media. However a lot of statements and comments on this subject are superficial, note well known facts and arguments and the main thing - do not reflect practically the real situation.

Acting Unified energy system had been established in line with the development of the former Soviet Union, namely the unitary state where former Union republics were not having any kind of autonomy and were considered only as a part of common territory.

But the situation changed after the collapse of the Union and its unified energy system while Central Asian countries had to face themselves their problems.

Functioning of the Central Asian Unified energy system in post-soviet period was ensured on “word of honor”, practically no powers and rights were left and the system became so vulnerable that some of its participants could uncontrollably and with impunity practice power takeoff in their own interests. Negative impacts of such actions for other countries are not taken into account.

In these conditions the operation of the Unified Central Asian energy system begun to be upset and that had serious negative impacts on the countries of the region and was bringing about grave conflict situations in the energy system. The example is that starting from March 2009 Kazakhstan suspended its participation in the Central Asian Unified energy system, Turkmenistan withdrew from this system in June 2003.

Because of continuing facts of non-coordinated actions, disobedience to instructions of Coordination control center and sometimes grave violation of parallel operation regimes of energy systems of certain countries participating in the Central Asian Unified energy system, systemic breakdowns and disturbance of dispatch control regimes occur.

On 9 November 2009 due to a systemic breakdown with automatic shutdown of machines on Nurek hydropower station in Tajikistan all the south part of Tadjik energy system was entirely interrupted and automatically stopped the work of all hydropower stations of Tajikistan on Vakhsh river, including the recently built Sangtuda hydropower station.

According to expert assessments, the break down occurred as a result of grave disturbance of technological regimes: avalanche type raise in volumes of energy consumption during morning rush hours, in the presence of reserve capacities power generation volume was considerably lower than the capacities of the system. In these conditions neither the automatic emergency system, switching off surplus consumers, neither dispatch services designed for a operational management of these processes did not work.

The accident has affected the energy system of Uzbekistan as well. As the result, emergency disconnection of transmission equipment main line in the Surkhandariya province; because of this, transmission of energy power was interrupted to neighboring Afghanistan through the power line – 500 kWt “Regar-Guzar”.

This situation impartially leads to two conclusions.

First of all, ensuring further activity of Central Asian Unified Energy System of the Central Asia and Coordinating Control Center “Energy” in current conditions without necessary credentials and rights is not possible. Systematic violations and illegal withdrawal of power energy from the network cause serious threat to stability and reliable work of national energy-systems.

Secondly, in future it is proposed to ensure all questions with regard to coordination of the work of the activity of national energy-systems on the basis of bilateral and multilateral agreements of the Central Asian states according to the international practice.

In current conditions of the work of Central Asian Unified Energy System there is a real threat to stability and safety functioning of the energy-system of Uzbekistan that raises the question of withdrawal from that system and working in separate regime.

The offender of developing events in such the direction is Tajikistan itself which systematically has violated agreements and established rules of activity of Central Asian Unified Energy System and Coordinating Control Center “Energy” as well as, because of illegal withdrawal of power energy, has caused serious problems for energy-systems of neighboring countries including Uzbekistan.

In such situation, Uzbekistan does not see a possibility of its further presence to the Central Asian Unified Energy System of the Central Asia, and none can deny the right of Uzbekistan to establish its own, reliable energy system.

One of the weak links in the operation of energy-system of Uzbekistan until recently was incoherency of its parts when power energy on whole territory of the south of the country was supplied from the territory of Tajikistan, from “Regar” substation.

During last two years State Joint Stock Company “Uzbekenergo” implemented consistent work on the loopback of the Uzbek energy system that has ensured its reliable and continuous operation.

At the end of November 2009 construction and putting into operation of power transmission equipment 500 Kwt “Guzar-Surhan” to be completed that allows to directly supply electro-energy to the Surkhandariya province. On 25th of November this power transmission equipment will be activated and since 1st of December 2009 – to be put to industrial use.

As a result free capacity of electric power of the Tadjik energy system, which is delivered earlier to the territory of Uzbekistan, can be used for internal needs of Tajikistan. In regarding to own consumption of Sogdian region of Tajikistan, they can be provided henceforth under the scheme established earlier.

As a whole, Uzbekistan in 2009-2014 plans to involve in development of the energy power industry $3,5 mlrd. investments for realization of 38 projects. In the sphere of generation of the electric power envisaged realization of 24 projects providing 2,7 thousand megawatt electric power, including in heat-and-power engineering system – 8 projects with generation of 2,255 thousand megawatt, in water-power engineering – 15 projects with generation 440 megawatt.

Also realization of 12 projects for making more than 1,4 thousand km of transmission lines and 1,754 megawatt transformations capacities on electric substations is planned. Besides, were begun introduction of the automated monitoring system and the energy power account.

Measures taken by Uzbekistan on maintenance of power safety allow to adjust steady functioning of power supply system and to create conditions for stable and reliable work of national power systems of the region countries.
