Haryana government has made it mandatory for all central and state government offices, public sector undertakings, institutions and establishments in the state to use LED (light-emitting diode) lamps.
The directive also applies to electricity consumers in industrial, commercial and institutional sectors having connected load of 30 kilowatt or more. The decision will save 380 MW of power, said Ankur Gupta, principal secretary, renewable energy.
Gupta said there is potential for 25-60% energy saving if LED lighting systems are used in place of T5 lights or CFLs. The figure would be higher if incandescent bulbs or ordinary tube lights are replaced with LED lights, he said, adding that LED lamps have the advantage of having a longer life, being non-toxic unlike fluorescent lighting that uses mercury.
The principal secretary said all defective conventional bulbs, conventional tube lights, CFLs and T-5 tube lights in central and state government offices and PSU institutions, would be replaced only by LED lamps or tube lights or other energy efficient lighting systems.
However, the industrial, commercial and institutional sectors having connected load of 30 kilowatt or above would have to replace all conventional bulbs, conventional tube lights, CFLs and T-5 tube lights in their establishments with LED lamps or tube lights or energy efficient lighting systems at their own cost within one year.
He said the state government has also banned purchase of new sodium vapour lamps and lights having efficiency less than that of sodium vapour lamps by government sector or government aided sectors or boards and corporation or autonomous bodies in the state.
He said in sectors under Haryana Urban Development Authority (HUDA), municipal areas, areas developed by Haryana State Industrial and Infrastructure Development Corporation (HSIIDC) or the industries department, the installation of automatic switching system—either solar based or timer based—for dusk to dawn operation has been made mandatory. It is for existing as well as new street lighting rows where a common switch for more than 25 lights are required.
