Street light power saving
It is possible to practically eliminate this wastage totally by installing electronic timer controlled street lighting hours with UPS back-up for control circuit. This device can be seasonally adjusted according to longer darkness is winter and considerably shorter in summer to achieve maximum power economy.
Consider the fact that despite best intentions a person may forget to switch off lights, if at that time the power is off. Losses in these circumstances could be much higher than Tk 90, 000 per hour.

By adopting a timer base control with UPS back-up, not only will money be saved but also manpower, which can be usefully re-deployed by the DCC in other much needed areas. The cost of incorporating the change may possibly not exceed Tk 1 crore, so recovery through savings can be achieved within five years.
May we request the DCC to carry out a feasibility study of the proposal to analyse the cost-benefit advantage and decide accordingly?
