The Ministry of Power, in consultation with the Bureau of Energy Efficiency, has issued new energy efficiency standards for domestic liquefied petroleum gas (LPG) stoves. Effective from 1st January 2026, all LPG stoves sold, imported, or manufactured in India must meet the IS 4246:2002 standard. Each LPG stove must carry a star label indicating its thermal efficiency, ranging from 1 Star (≥68%) to 5 Star. Testing must follow IS 4246:2002, with no negative tolerance allowed. The lowest efficiency burner determines the star rating. Only stoves certified by BIS and tested by NABL/ILAC/APAC/CSIR-approved labs are eligible. Manufacturers must register through the Standards & Labeling Portal and submit test reports for three stove samples. These rules aim to promote energy-efficient LPG stoves, reduce gas usage, and support energy conservation in India.
