ISO 50001 – 2011

ISO 50001:2011 Energy Management System

  • ISO 50001- the International Standard for Energy Management Systems (EnMS)
  • Energy Management Systems offers a comprehensive and structured  approach for energy efficiency improvement.
  • ISO 50001: 2011 defines EnMS as “set of interrelated or interacting elements to establish an energy policy and energy objectives, and processes and procedures to achieve those objectives.”
  • Applicable to any organization, whatever the size, industry or geographical location
  • An organization embracing ISO 50001 is likely to further accelerate adoption of energy efficiency practices and to continuously improve its energy performance and cost.


Adoption of ISO 50001 by any organization will:

  • Reduce energy bills
  • Make manufacturing more sustainable
  • Promotes energy efficiency throughout the supply chain
  • Helps in meeting  National GHG reduction targets

Approach of Standard:

  • ISO 50001 specifies requirements for  an organization to establish, implement, maintain and improve an energy management system.
  •  Specifies energy management system (EnMS)  to :
  • develop and implement an energy policy,
  • establish objectives, targets, and action plans which take into account legal requirements
  •  This International Standard specifies requirements for all factors affecting:
  • energy supply, uses and consumption
  • measurement, documentation and reporting,
  • design and procurement practices for energy using equipment, processes, systems, and personnel.
  • ISO 50001 is based on the Plan – Do – Check – Act (PDCA) continual improvement framework and incorporates energy management practices into everyday organizational activities.
  • Plan: conduct the energy use assessment, establish the baseline, energy performance indicators (EnPIs), objectives, targets and action plans necessary to deliver results that will improve energy performance (measurable results related to energy efficiency, use and consumption) in line with the organization’s energy policy;
  • Do: implement the energy management action plans;
  • Check: monitor and measure processes and the key characteristics of operations that determine energy performance against the energy policy and objectives, and report the results;
  • Act: take actions to continually improve energy performance and the EnMS.

Implementation Steps

  1. Gap Analysis
  2. Awareness Training
  3. Energy Policy and Energy Objectives Finalization
  4. Energy review- determination of Energy performance for identification of energy saving opportunities
  5. Energy baseline- establishing basis for energy performance comparison.
  • Energy performance indicators (EnPIs)- setting EnPIs,  measure of energy performance.
  1. Documentation/Process Design
  2. Documentation / Process Implementation
  3. Internal Audit
  4. Corrective Action to close non conformances
  5. Management Review Meeting
  6. Stage 1 Audit by Certification Body
  7. Corrective Action to close non conformances if any
  8. Stage 2 Audit by Certification Body



Cost of consultancy is ultimately determined by factors such as the organisation’s size, its industry, number of employees, number of locations and choice of Certification Body.
