What is Energy Conservation Act and BEE?

No. It also underpins appliance star labeling and the building codes, so commercial property owners and equipment makers fall under different parts of it. A hotel or office meets it mainly through the building code at design, while a cement plant or dairy meets it through PAT targets.

Its value is set by trading, so a plant that overachieves its PAT target can sell surplus certificates to one that falls short. That makes the measured specific energy consumption commercially important, and it is why sub-metering by production line is worth the effort.

Designated consumers file energy returns every year and are assessed at the end of each PAT cycle against their specific energy consumption target. Aqueduct keeps the energy and production-normalized figures by line through the cycle, so the accredited energy auditor's verification starts from metered data rather than reconstructed estimates.
