Delhi to switch off lights for Earth Hour on Saturday

People across the city will unite to turn off non-essential lights and appliances from 8.30 pm to 9.30 pm on Saturday.

This action is part of Earth Hour 2026, the world’s largest grassroots environmental movement, and will connect us with millions around the globe.

In a statement, city power discoms have urged Delhiites to participate in Earth Hour on Saturday by turning off non-essential electrical appliances between 8.30 pm and 9.30 pm to promote a sustainable environment.

BSES discoms BRPL and BYPL have joined the event promoted by WWF-India.

This year’s initiative is themed “Give an Hour for Earth,” calling on citizens to dedicate one hour to the planet and inspire lasting change.

“As a proud partner of WWF-India, BSES has urged its around 54 lakh consumers and 2.25 crore residents across South, West, East and Central Delhi to participate in this global movement,” the discom said in a statement.

Last year, Delhi saved 269 MW during Earth Hour. From homes and markets to offices and public spaces, the city will unite in turning off non-essential lights and appliances during this hour in a collective act that emphasises a shared commitment to sustainability.

To promote awareness around Earth Hour, BSES is undertaking a multi-channel outreach campaign, including messages through its Samvad newsletter reaching around 53 lakh consumers, SMS campaigns, digital platforms, and engagement with RWAs and institutions, along with active employee participation. In addition, BSES will switch off non-essential lighting across its 400+ offices spread over approximately 900 sq km during the designated hour. BSES plans to switch off non-essential lighting in over 400 offices covering approximately 900 square kilometres during the designated hour.

In a statement, the Tata Power Delhi Distribution Limited (TPDDL) said that it has reached out to resident welfare associations (RWAs) and other consumers to spread awareness about Earth Hour. The discom has also approached students and teachers across 150 schools, as well as residents of 218 slum clusters in the city.

Launched in 2007, Earth Hour has grown into a global movement spanning over 190 countries and territories, inspiring individuals, communities and organisations to take action for the planet.

Earth Hour 2026 also marks two decades of a movement that has grown from a symbolic switch-off in Sydney in 2007 into a defining global call for climate action across more than 190 countries and territories. Over these 20 years, Earth Hour has evolved from awareness to action—mobilising individuals, communities and institutions to adopt more sustainable lifestyles and accelerate the transition to a low-carbon future. In many ways, it reflects the journey the world must take—from intent to impact.
