Current Grid Infrastructure Challenges Along Tashkent’s Ring Road
While Tashkent’s Ring Road spans approximately 120 kilometers around the capital city, the existing electrical grid infrastructure exhibits significant capacity limitations that impede large-scale EV charging deployment. The distribution network operates at 6-10 kV transmission levels with aging transformer substations that cannot accommodate the instantaneous power demands of Level 3 DC fast charging stations, which typically require 50-350 kW per unit.
Grid reliability issues manifest through voltage sags exceeding IEEE 1159 standards during peak loading periods. The network experiences energy demand fluctuations ranging from 40% to 180% of baseline consumption, creating power quality disturbances that compromise charging station performance.
