Energy Losses

IDGC of Centre presented its results in the area of energy conservation and energy efficiency at the ENES 2013 forum

IDGC of Centre participated in the Second Energy Efficiency and Energy Saving Forum ENES 2013.

Actual energy losses in the power grids of IDGC of Centre in 2013 totaled 5.8 bln kWh (9.16% of power supply to the grid). The amount of losses dropped by 0.3 bln kWh (0.37% of power supply to the grid) vs. 2012.

CHANGE IN ENERGY LOSSES IN 2011-2013, %::

Indicator 2011 2012 2013 Change,

Loss, actual, % 9.93 9.53 9.16 – 0.37 ppt
Loss, plan, % 9.93 9.78 9.43

CHANGES IN ELECTRICITY LOSSES IN 2011 – 2013, %:

Optimization of energy losses is one of IDGC of Centre’s business priorities. Implementation of a set of measures aimed at reducing the level of losses in 2013 resulted in saving 235 mln kWh of energy, which equaled 675 mln RUB. The economic benefit of 2013 exceeded the figure of 2012 by 3.2% (21 mln RUB).
In general, these measures can be divided into three areas: organizational measures, technological measures and measures to improve the system of electrical energy billing and metering.
