OREANDA-NEWS. April 25, 2007. Optimization of power energy losses in JSC “IDGC of Center and North Caucasus” is a priority in cost management of power energy transportation, reported the press-centre of  JSC “IDGC of Center and North Caucasus”. “The order of loss reduction program formation in RNC power networks” was approved last year in December, in which the ways of planning and implementing loss reducing activities were unified.


Within this framework, the planned effect from” activities, aimed do reduce losses, implemented by JSC “IDGC of Center and North Caucasus, will equal 397,9 mln kWh in 2007, including the expenses for organizational arrangements - 81,1 mln kWh, technical arrangements - 53,1 mln kWh, and activities aimed at developing commercial and technical accounting - 263,7 mln kWh. Loss reduction in power networks is mainly influenced by eliminating the technical disfunctions in the commercial accounting system, installing accounting meters shields on building sides, cable replacement for bigger diameter ones, replacement of overloaded transformers, and cables for SIW ones, etc.  The total effect as a result of, applying this program last year equaled 380,19 mln kWh. JSC “IDGC of Center and North Caucasus” reduced power energy losses in 2006 by 0,64 percentage points. The power energy losses in 2006 equaled 9,82%  of supply to networks against 10,46%  in 2005 in the same area of distribution networks.


The reduction of technical power energy losses is made possible by replacing overloaded equipment - 660 supply transformers and 40260 km of overhead transmission lines, optimization of power networks load by constructing 3471,2 km of power transport lines and commissioning 57 747,4MBA substations. Apart from that, 6 automated directory and documentation systems (ADDS) and 522,5 ths of high accuracy class electric meters were installed, measures to reduce power consumption for substation auxiliaries, the effect amounted to 19,85 kWh. To reduce commercial power energy losses the power energy company staff uncovered and stopped unauthorized consumption of power. Over 6,27 mln raids took place to liquidate breakdowns in technical operation of the measurement system as well as unauthorized power consumption. Following the results of 2006, 28,17 ths of violations, were discovered the 250,6 mln kWh were returned to the supplier. The effect from loss reduction in the networks due to these activities is estimated at 380,2 mln kWh in 2006.


The final objective of loss reduction in the networks should be controlled over tariff growth rates for customers and cutting the financial expenses of regional network companies.
JSC “FNC UES” (the operator of the Unified National (All-Russian) Energy System of Russia), the IDGC shares of which are in trust management, managed to reduce power energy losses in its networks by 0,04 percent points (from 3,75% to 3,71%  supply from networks) in 2006. The situation in power energy losses has improved in the distribution network complex on the territory of the entire country. Power energy losses in 2006 amounted to 8,69% from supply to the networks. In comparison, in 2005 the losses in the distribution networks were 10,02%/ This was achieved due to the implementation of the master plan on power energy loss reduction in the networks of all voltage ratings in RAO UES. The document were approved by a JSC “RAO UES of Russia” order and is valid till 2008. Programs to reduce power energy losses are being developed and implemented, as well as incentives for personnel and personal responsibility mechanisms for their execution.
