Power discoms in the city are gearing up for 9th edition of the event by sending mobile text messages and memos to individual households, RWAs, business houses and communities urging them to switch off all lights for an hour to conserve energy.
The discom appeals to its customers to unequivocally support the event and voluntarily switch off their non- essential electricity on the March 28 for an hour staring 8:30 pm.
"We are sending SMSes to over 10 lakh customers to participate in the Earth Hour," a BSES official said.
"As a responsible organisation, BSES is committed to reduce green house emissions and the impact of global warming. We should all strive for the day, when we don't need an Earth Hour. BSES and its consumers are once again gearing up to take up the challenge and take the Earth Hour event to greater heights," a BSES spokesperson, said in a press release.
Last year, Delhi saved around 250 MW (175 MW in BSES area).
On their part, BRPL and BYPL will also switch off all non- essential lights at their over 400 offices, spread across an area of around 950 sq kms, during the appointed hour.
