The Government of India has enforced The Energy Conservation Act, 2001 (No 52 of 2001, 29th September 2001) with effect from 1st March 2002. The Act provides mainly for efficient use of energy and its conservation and for matters connected therewith or incidental thereto. As per the Energy Conservation Act 2001, it is mandatory for all the designated energy consumers to get energy audit conducted by an Accredited Energy Auditor [under clause 14(h) and 14(i)] and to designate or appoint an Energy Manager [under clause 14(l)]. The Government of India has notified the list of designated consumers and the details are available at the following link: http://www.bee-india.nic.in/sidelinks/Exams07/Gazette_of_IndiaPartIISec3Sub-sec(ii)19_03_2007.pdf
