The paper analyses possibilities of a hard coal mine operation as an electricity consumer capable of reducing instantaneous demand for electric power in the case of a Demand Side Response (DSR) call. The analyses considered the risk of service provision or non-provision based on the 2018 data on the electricity consumption and on parameters of the Polish power system. The analyses applied to two types of DSR participation programmes: guaranteed and current, and to an example of hard coal mine from the area of the Upper Silesia, which ordered power was 20 MW. For the current programme (without fines for service non-provision) the optimum value – from the financial risk point of view - was calculated as 6 MW, and for the guaranteed programme results were determined depending on the ratio of price for service provision to the fine for non-provision.
