Energy Management

• Addresses high Energy intensive sectors
• Formulation of energy saving plan
• Load management
• Implementation of power saving devices
• Usage of standard devices
• Mandatory Testing / Certification of Electrical
  Appliances
• Mass awareness through Press Electronic Media

Energy Conservation in India

• In India, government has passed an energy
  conservation bill, 2010 for better utilization of
  energy and conservation.
• By this act, it is mandatory for energy intensive
  sectors to get their energy Audit "conducted by
  accredited energy auditor.
