Hourly resolution is essential to realistically address the matching of supply and demand for fluctuating energy sources like solar wind. This work introduces a novel method model variability in an Integrated Assessment Model building upon previous work, where regression analysis was utilized extract hourly-level information from system model. The enhancements include: (1) improved experimental design more efficient computing, (2) modelling management integrated assessment by (i) incorporating portfolio flexibility options, (ii) offering ability regulate curtailment limiting expansion renewables. scenarios focus on electricity sector, mirroring current Europe-27's policies that aim higher renewable electrification contributions 2050. Without any control measures, significant (up 60%) observed, introduction options reducing it half (30%). Controlling capacity renewables introduced avoid these unrealistically high curtailment, allowing achieve penetration 80% 53% reduction greenhouse gas emissions compared 2015 levels system. In conclusion, methodology employed yields consistent outcomes.
