The new developed methodical approach to an estimation of contributions of a gas complex in power safety of territories of a regional level is stated. The approach is based on allocation of specific parameters of influence of gas branch on formation of indicators of the power safety structured on objects of its monitoring. Are entered the concept of the potential contribution of branch counted on corresponding parameters of power safety, and the contribution to creation of a crisis situation, and also direct and indirect contributions and ways and formulas of their estimation are developed. Calculations by definition of contributions of a gas complex in power safety of subjects of the Russian Federations entering into the Ural federal district are executed, and their results are resulted.

Some results of authors are discussed, namely: methodical approach to estimation of power-investing attractiveness of regions; method of its calculation for a task of attractiveness of coal delivery to the 17th regions of Russian Federation situated in the Urals, Western Siberia and Volga zone. The approach applies diagnostics of economic and power safety by using of indicative analysis.

Substantive provisions of the developed modified variant of a complex method of diagnosing and forecasting of development of a situation on power safety of the territories of a regional level are stated. The methodical approach allows to investigate influence of regional and branch factors on formation of a safety situation. Results of calculations of diagnostics and analysis of development of the situation on power safety for 79 subjects and seven federal districts of the Russian Federation for last seven years are discussed. Results of forecasting of development of situation on one of important parameters of power safety of the Ural federal district and it's regions are shown.
