CHENNAI: With rapid industrialisation and urbanisation of the State over the years, the rising need for power has put tremendous pressure on infrastructure and resources of the Tamil Nadu Generation and Distribution Corporation (Tangedco). The need for additional budgetary allocation is rising every year as the State power utility, which has a loan burden of more than Rs 1,50,000 crore and average annual revenue gap of Ts 12,000 crore, has to spend crores on new poles, transformers, EB meters and substations for new connections each year.
