This paper assesses the impact of flexible thermal uprating methods and the utilization of the emergency loading capability of overhead line (OHL) networks on network transmission adequacy and flexibility. It implements electrothermal modelling of OHLs within a network reliability evaluation analysis to capture the risk of ageing during the operation and then performs a cost/worth analysis of the value that extensive emergency loadings could have on the network performance. The preliminary results indicate that increased emergency rating durations could increase network flexibility for operators during unexpected events, however, on the cost of increased ageing. Time varying line rating (TVLR) is the optimal solution as it provides increased flexibility without increasing the risk of conductor ageing
