Analysis of correlation between the energy demand and electricity rate and environment temperature at the competitive market of the Ural Grid Company of unified energy system

The article covered the electric energy consumer's reaction on tariffs and ambient temperature changes in the Unified Energy System of the Ural in the period of time after restructuring RJSC «UES of Russian Federation». Factual data of Unified Energy System of Russia's System operator shows how indicator values of electric energy consumption elasticity changes with shifting of the youngest competitive markets of electric energy and power in Russia to stationary operating condition: consuming turns from elastic to inelastic according to price. Linear correlation coefficients were calculated for the volume of consumption and the ambient temperature; Rate day-ahead market and temperature; consumption and the market rate on the day-ahead data for 2009 — 2014. Proved an inverse relationship of consumption of electrical energy from the ambient temperature, what confirms the actual transition to a competitive market of electricity production.
