Abstract:	Termoelektrarna Toplarna Ljubljana d. o. o., (v nadaljevanju TE-TOL, d. o. o., Ljubljana), že vrsto let proizvaja električno energijo in ogreva prebivalce mestne občine Ljubljana. Od začetka delovanja, leta 1967, do danes se je marsikaj spremenilo. TE-TOL, d. o. o., Ljubljana že ves čas svojega delovanja kot primarni energent za pridobivanje električne in toplotne energije uporablja premog. Najprej je uporabljal slovenski premog iz rudnikov Trbovlje in Velenje, nato je leta 2001 začel uporabljati samo indonezijski premog z višjo kurilno vrednostjo in boljšimi okoljskimi karakteristikami, manj žvepla in pepela. Od leta 2008 v kombinaciji s premogom uporablja tudi lesne sekance. Danes je problematika obremenjevanja okolja in ozračja vedno bolj v ospredju, kar dokazuje tudi nova zakonodaja na tem področju. Tudi v TE-TOL, d. o. o., Ljubljana se tega dobro zavedajo, zato so začeli uporabljati tudi lesne sekance. Lesna biomasa (lesni sekanci) so eden izmed čistejših virov energije. Njihova kurilna vrednost je visoka, trdni ostanek pa precej manjši, saj v primerjavi s premogom bolj dogorijo. TE-TOL, d. o. o., Ljubljana že tretje leto uporablja tudi lesne sekance in proizvaja čistejšo električno in toplotno energijo. Električno energijo prek stikališča oddaja v električno omrežje Slovenije, toplotno energijo pa prek Energetike Ljubljana, d. o. o. v ljubljanski sistem daljinskega ogrevanja. Poleg daljinskega ogrevanja je zadnje čase veliko govora tudi o daljinskem hlajenju, ki bi lahko v poletnem času nadomestilo klimatske naprave, ki so zelo velik porabnik električne energije in posredno tudi velik obremenjevalec okolja.

Title:	USE OF WOOD CHIPS FOR PRODUCTION OF ELECTRIC AND THERMAL ENERGY IN TERMOELEKTRARNA TOPLARNA LJUBJANA, D. O. O. (POWER AND HEATING PLANT LJUBLJANA)
Abstract:	Termoelektrarna Toplarna Ljubljana d. o. o., below TE-TOL, d. o. o., Ljubljana (Power and Heating Plant Ljubljana, d. o. o.) has been producing electric and thermal energy for inhabitants of the Ljubljana municipality for many years. Since the very beginning in 1967 until nowadays, there have been considerable changes. TE-TOL, d. o. o., Ljubljana has been using primarily coal to produce electric and thermal energy over all those years. First, they used Slovene coal from the coal-mines in Trbovlje and Velenje, and in 2001 they started using only Indonesian coal with higher calorific value and better environmental characteristics: less sulphur and ash. Since 2008, they have also been using wood chips in combination with coal. Nowadays, environmental and atmospheric pollution is becoming an increasingly significant issue, which is also indicated by the new legislation in this area. TE-TOL, d. o. o., Ljubljana is well aware of that, and as a result they started using wood chips. Woody biomass (wood chips) is one of the cleanest energy sources. Its calorific value is high, and there is relatively little waste, since it burns down better as compared to coal. TE-TOL, d. o. o., Ljubljana has been using also wood chips for three years and therefore it produces cleaner electric and thermal energy. It sends electric energy through junction centre to the electricity network of Slovenia, and thermal energy through Energetika Ljubljana, d. o. o. to the district heating system in Ljubljana. In addition to district heating, district cooling has often been discussed lately, which would be used instead of air-conditioning systems in the summer; energy consumption for such systems is huge, and they also contribute to environmental pollution.
