  As the frequency and intensity of tropical cyclones, and the degree of
urbanization increase, a systematic strengthening of power transmission
networks in the coastal regions becomes imperative. An effective strategy for
the same can be to strengthen select transmission towers, which requires
consideration of network at holistic scale and its orientation relative to the
coastline, the fragility of towers, and properties of cyclones. Since necessary
information is often missing, actionable frameworks for prioritization remain
elusive. Based on publicly available data, we assess efficacies of strategic
interventions in the network that serves 40 million people. After evaluating 72
strategies for prioritization, we find that strategies that consider rather
simplistic properties of the network and its orientation with respect to the
coastline work much better than those based purely on the network's properties,
in spite of minor variations in fragilities of towers. This integrated approach
opens avenues for actionable engineering and policy interventions in
resource-constrained and data-deprived settings.
