In 2014, the Company started implementation of Techniques reducing investment costs by 30 percent vs 2012 applicable to investment programs (adjustments) of JSC IDGC of the North-West. In 2014, the Techniques helped reduce Company’s investment costs by 11.93%, against planned 7.5%. By 2017, it is planned to further reduce specific investment costs with a yield of 30% vs 2012 (in RUB per capacity (km, MVA)).

One of the main objectives of the Program of energy saving and energy efficiency (hereinafter — the Program) of the Company, launched in 2011, is to reduce electricity losses during transmission. Among other Program measures, investment projects in which the effect of reducing electricity losses is concomitant are also implemented. However, since its’ launch, the Program helped reduce losses from realization of investment projects on the whole in the Company by 20.97 million kW⋅h.

A more detailed analysis of the decrease/increase of electricity losses during transmission in grids is available in section “Reduction of Electricity Losses”.

For the past five years, the Company observed a steady increase in the number of executed contracts for grid connection, especially under contracts with “privileged” category of applicants, which is driven by the Company’s efforts to organize the process of grid connection.

In 2010-2014, in order to ensure the sustainable development of territories in the regions of operation as part of implementation of the investment program, the Company commissioned 26 previously closed 35-110 kV main substations.

Despite the fact that more than 70% of the investment program funds is annually directed on modernization and refitting, in recent years, there is an increase in the level of depreciation of fixed assets. However, the Company is developing and implementing measures aimed at maintaining the required level of reliability of the electric grid complex. This is primarily achieved by carrying out a full range of diagnostic procedures using modern instruments (thermal, gas chromatographs, and others) and methods, as well as defining the necessary amount of effect on the equipment. The analysis of the most typical causes of accidents and the formation of programs aimed at their elimination. Thus, the implementation of the programs on expansion and clearing of the overhead line routes from trees and shrubs reduced the number of outages due to branches and trees falling on wires in 2014 by more than 27%. Particular attention is given to equipping subdivisions with special tools and increasing the level of personnel training, which allows to increase the quality of maintenance work and reduce the time spent on liquidation of damages.

Improving the reliability of electricity supply to consumers in the reporting year became possible due to the successful execution of the maintenance and investment programs in 2014, effective analysis of technological failures, revealing their causes, as well as through coordinated actions of the personnel involved in emergency and recovery operations. Based on the received data, according to the analysis of technological failures, the production programs are adjusted, reallocation of resources is performed to eliminate the problematic elements of the power grid complex of JSC IDGC of the North-West.

At JSC IDGC of the North-West in the grids of 6 kV and above during the reporting period:
