Assessing the efficiency of replacement of gas by coal in energy balance

The paper analyses, by applying a system of optimization models for cash flow analysis and forecasting, how effective a transfer of a part of the power generating capacities from gas to coal would be. We present a scenario analysis assuming both an increase of a gas export under a deficit of the time required to cover the demand exceeding those under the contracts already concluded, and the same volume of electric and thermal power produced. We assess the efficiency of such process from the point of view of the RF consolidated budget and gas and power producers.
