Opis:: The article presents a case study on the effectiveness of photovoltaic farm and battery energy storage in one of the Polish foundries. In the study, we consider two investment options: stand-alone PV farm of 1MWp and the farm together with battery energy storage with a maximum capacity of 4MWh. The Payback Period and Net Present Value were used as measures of investment profitability. The paper provides a detailed presentation of the assumptions made, as well as the PV electricity production model of the farm and the optimization model that determines the operation cycle of the energy storage. The case study presented in the article shows that the PV farm is economically sensible and profitable, but the battery energy storage is too costly to give a positive economic effect. Energy storage is an important element that provides flexibility in the energy supply system, so it is necessary to find a technical solution that gives this flexibility. Such a solution could be a virtual power plant, which could include a foundry energy system with a RES installation inside.

Opis:: On the beginning, there had been characterised Katowice Coal Holding Stock Company - one of the largest consumers of energetic media in Poland, which, in second part of 2002 year entered a competitive electrical energy market and for a number of years carries on optimising process of its consumption. Subsequently there was talked over particular stages of rationalization of energetic media consumption. Much attention was dedicated to initiated program that refers to aspect of "daily quality and quantity controlling" and "monthly cost and financial controlling". There was shown its mission, objectives and peculiarity of its working in hard coal mining craft. The description of the energetic media management program is crowned with presentation of consumption level and gained effects in years 1996-2004 for particular energetic media. There has been proved that active management of energetic media returns positive financial results. Summation of Katowice Coal Holding, Stock Company activity in the field of media management in years 1996-2004 gives following reduction for one ton of produced coal: - in unitary consumption of electrical energy by ~ 16,8 %, - in unitary consumption of thermal energy by ~ 46 %, - in unitary consumption of compressed air by ~ 29 %, - in unitary consumption of drinkable water by ~ 38,2 %.
