TIMES-CZ
Model of the Czech Energy System including the whole energy ballance
• based on Czech region of TIMES-PanEU
• Updated from 2010 to 2012 data
• ETS sectors disagreated on plant level (except Iron and Steel industry)
• Non-ETS sectors as in TIMES-PanEU
• time horizon 2012-2050
• 5 year periods
• ETS sectors: plant-level data of fuel use, emissions and electricity/heat generated
• District heating partly regionalized
• RES potentials based on State Energy Policy (SEP)
• Reserves of brown coal according to 4 variants of territorial ecological limits
• Capital costs of new technologies based on DIW (2013)
• Fuel cost base on World Energy Outlook 2014

Conclusions
• ‘breaking’ of the territorial ecological limits does not have significant affect of Czech energy system under most of assumption sets
• Fuel and EUA prices have higher impacts on Czech energy systém than availability of bronw coal
• Approximately 3 mil. t of brown coal would need to be
imported in case of not ‘breaking’ of the territorial ecological limits
• RES are at least competetive with nuclear sources at EUA price at 40€
• Sensitivity analysis shows fuel switch btw Hard coal and Natural gas
