Policy questions and UCC Energy Models
• what is the appropriate mitigation target for Ireland?
• Irish TIMES energy systems modelling – least cost technology roadmap
• what emissions reductions will specific policy measures deliver?
• LEAP_Ireland simulation modelling – policy roadmaps
• how confident are we that policy measures will deliver?
• scrutiny and ex-post analysis of enabling measures
• what are the implications for the power system and gas system of increased RES?
• PLEXOS electricity and gas modelling

Scenario analysis to address uncertainty
• Irish TIMES finds least cost pathway to meet energy service demands and policy constraints
• Assumptions in all scenarios- macro drivers from ESRI economic projections – fuel prices from IEA WEO 2012 – technology dbase from PET, DECC, JRC –
1. BaU – business as usual – unlikely but useful reference
2. CO2-80 – 80% reduction in 1990 CO2 emissions by 2050
3. No CCS – CO2-80 but with no CCS option
4. No BioImp – CO2-80 but with no bioenergy imports allowed
5. ILUC- – CO2-80 but indirect land use emissions accounted for
