It results from the variant-oriented prospective programme for Polish power industry with a time horizon until the year 2010 that compared to 1997 the electric energy consumption till 2020 will increase by 36-63 percent depending on the economic development scenario. Lignite as fuel for more than 35 percent of electric energy generated non in Poland at the lowest cost should be also correspondingly considered in satisfying planned prospective requirements. For this reason, in all productive lignite mining areas and also, in those prospective, programmes are drawn up for further use of this fuel in the power industry. Thus in such an operating lignite mines. the following development actions are foreseen to be taken: * in Adamów Mine, the continuation of mining activity till 2021 will be possible owing to starting with mining operations at new Koźmin-Północ Open Pit,. * in Bełchatów Mine, the continuation of mining activity till 2038 will be possible owing to the construction of new Szczerców Open Pit, * in Konin Mine, it is planned to continue mining activity till 2037 owing to putting six new open pits in to operation, * in Turów Mine, owing to the in-depth modernization of equipment fleet, it is planned to continue mining activity till 2035. Furthermore, it is planned to manage one satellite deposit (Złoczew, Kamieńsk or Gorzkowice) to extend life of .Bełchatów Power Plant with increased by 800 MW generating capacity untii 2052. Also, the industrial management of Legnica coal field is included in these plans. The management of aforesaid field in the years ~2015--2095 will allow to construct new power plant of apporox. 3000 MW capacity what will enable to partially compensate substantially production of electric energy based on the lignite in the years 2020-2040. The implementation of these projects will allow to maintain until 2020 contribution of lignite in satisfying energy requirements of this country at a level of not less than 25-30 percent which, however, in comparison with the present-day contribution of this fuel in electric energy production equalling nearly 36%, will be still a substantial restraint.
