DHBVN officials said as per the feedback received from the field officers, about 70 per cent agriculture and industrial consumers have switched over to the use of compact fluorescent lamps and other energy efficient lighting system for tubewells and factory lighting in January following instructions issued by DHBVN to replace all traditional bulbs. The remaining consumers would be motivated by DHBVN officials to switch over to the energy efficient lighting system by February 29.

For conservation of electricity, the DHBVN has asked consumers to stop the use of incandescent bulbs. It is now mandatory to use energy efficient compact fluorescent lamps (CFLs) in Sirsa, Fatehabad, Hisar, Bhiwani, Mahendragarh, Rewari, Gurgaon, Mewat and Faridabad.

As per an estimate, replacement of all traditional yellow bulbs and tubelights would result in saving of about 60 MW power.

DHBVN has already made compulsory the use of CFLs for applicants seeking new connections of any category and the government of Haryana has already made use of CFLs or tubelights in government buildings mandatory. Use of efficient lighting system is mandatory for all industrial units and commercial complexes having more than five KW load.

DHBVN was probably the first electricity utility in India to make use of CFLs, instead of incandescent bulbs, mandatory for lighting for new connections in the domestic sector in April, 2007.
