Efficiency of energy is now more essential for the Indian industries in order to minimise energy losses and ensure efficient operations. As stated by the Bureau of Energy Efficiency (BEE), its Perform, Achieve and Trade (PAT) scheme includes 1,333 energy-intensive industries, representing about 55% of the energy consumed by the industries of India.

ISO 50002 energy audit offers a way to carry out assessment of energy consumption, analysis of energy performance, and determination of possibilities for improvement. ISO 50002-1:2025 describes in detail requirements and guidelines for such audits.

In case you need ISO 50002 certification in India, one should be aware that ISO 50002 is an energy audit standard, and not a traditional certification standard of the management system. Below, we present the latest requirements of ISO 50002, audit procedure, connection with BEE, cost of certification, and preparation for ISO 50002 energy audit.

What Is an ISO 50002 Energy Audit

The energy audit based on ISO 50002 is a structured analysis of how an organization manages its energy consumption within its facilities, equipment, and processes. An energy audit evaluates energy consumption, operation conditions, and performance with the goal of identifying energy losses, inefficiencies, and areas where improvements can be made.

An ISO 50002 energy audit is carried out according to the standards set out in ISO 50002-1:2025 and can be used as a standalone tool or in support of energy review required by ISO 50001.

ISO 50002-1:2025: What Is the Latest Standard

ISO 50002-1:2025 is the current general standard for energy audits. It replaced ISO 50002:2014 and provides an updated framework for planning, conducting, and reporting energy audits. The ISO 50002 series includes:

Is ISO 50002 a Certification Standard

No. ISO 50002 is primarily an energy-audit standard, not an organisation-level management-system certification standard. This distinction matters because the phrase “ISO 50002 certification” is often used when an organisation is actually looking for an ISO 50002-based energy audit. The standards serve different purposes:

  • ISO 50002 provides requirements and guidance for conducting energy audits.
    ISO 50001 provides requirements for an Energy Management System that organisations can have certified.
    BEE requirements apply to organisations covered by India’s applicable energy-efficiency regulations.

Why Conduct an ISO 50002 Energy Audit in India

Energy costs, production demands and operating conditions can make it difficult for organisations to identify inefficiencies simply by reviewing utility bills. A structured audit looks deeper into the systems and processes responsible for energy consumption. An ISO 50002-based audit can help organisations:

  • Identify major energy-consuming areas
  • Understand energy-use patterns
  • Detect potential inefficiencies and losses
  • Identify energy performance improvement opportunities
  • Support energy-efficiency investment decisions
  • Prioritise practical improvement measures
  • Support ISO 50001 implementation
  • Contribute to wider energy and sustainability objectives

Who Can Benefit From an ISO 50002 Energy Audit

ISO 50002-1:2025 is designed for organisations of different sizes, sectors and locations. It can be useful for:

  • Manufacturing facilities
  • Engineering companies
  • Automotive and auto-component plants
  • Textile and garment units
  • Cement and construction-material manufacturers
  • Steel and metal industries
  • Chemical and pharmaceutical facilities
  • Food and beverage plants
  • Paper and pulp industries
  • Warehouses and logistics facilities
  • Commercial buildings
  • Hotels and hospitals
  • Data centres
  • Educational institutions
  • Multi-site organisations

ISO 50002 Energy Audit Requirements

An effective energy audit requires more than reviewing electricity consumption. It should be planned around the facility, its energy uses and the objectives established for the assessment.

Audit Scope and Boundaries

The organisation and auditor establish the facilities, processes, systems, energy sources and areas that will be assessed.

Energy Data Collection

Relevant information may include electricity and fuel consumption, production data, equipment details, operating schedules, utility records and previous audit findings.

Measurement and Site Assessment

Where required, measurements are planned and collected to understand actual operating conditions and energy use.

Energy Performance Analysis

Collected information is analysed to understand consumption patterns, significant energy uses and areas where performance can potentially be improved.

Energy Performance Improvement Opportunities

The audit identifies opportunities for improving energy performance based on the findings and agreed audit objectives.

Reporting

The findings, analysis, and recommendations are documented in an energy audit report appropriate to the agreed scope and audit level.

ISO 50002 Energy Audit Process in India

Here is the complete process for the ISO 50002 energy audit process in India:

Step 1: Audit Planning and Scope Definition

Define the audit objectives, facility boundaries, energy sources, major energy uses, and information required for the assessment.

Step 2: Energy Data Collection and Measurement

Collect relevant energy, production, and equipment data and carry out required measurements to understand actual energy consumption and operating conditions.

Step 3: On-Site Assessment and Energy Analysis

Inspect the facility, processes, and equipment, then analyse energy consumption and performance to identify significant energy-use areas and potential inefficiencies.

Step 4: Identify and Evaluate Improvement Opportunities

Identify suitable energy performance improvement measures and evaluate their technical feasibility, expected savings and, where applicable, financial considerations.

Step 5: Energy Audit Report and Recommendations

Document the audit findings, analysis, and recommended improvement measures in a clear report and present the results to relevant stakeholders for further action.

ISO 50002 Energy Audit and BEE Requirements in India

ISO 50002 and India’s Bureau of Energy Efficiency (BEE) framework serve related but different purposes.

BEE maintains an official framework for Accredited Energy Auditors under India’s energy-efficiency regulations. Certain designated consumers in energy-intensive sectors are also subject to specific energy-audit requirements under the applicable BEE and Energy Conservation Act framework.

This means organisations should not assume that an ISO 50002 energy audit automatically satisfies every applicable BEE requirement. Where statutory requirements apply, the relevant BEE provisions and auditor requirements should be considered separately.

ISO 50002 Energy Audit Support Across India

Global Quality Services provides consultancy support to organisations across India, including businesses operating in major industrial and commercial locations such as Bengaluru, Chennai, Mumbai, Pune, Hyderabad, Ahmedabad, Delhi NCR, Surat, Vadodara and other locations.

Rather than applying the same approach to every facility, the consultancy process can be planned around the organisation’s industry, energy profile, facility characteristics and audit objectives.

ISO 50002 Energy Audit and ISO 50001

ISO 50002 and ISO 50001 address different but closely connected areas. ISO 50002 focuses on conducting an energy audit and evaluating energy use and improvement opportunities.

ISO 50001 establishes requirements for an Energy Management System designed to help organisations systematically improve energy performance.

An ISO 50002-1:2025 energy audit can therefore provide useful input to the energy-review process under ISO 50001. ISO confirms that the audit standard can be used alongside ISO 50001 or independently.

ISO 50002 Energy Audit Cost in India

There is no single cost for every ISO 50002 energy audit. The scope and complexity of the facility determine the level of effort required. Factors that can affect the cost include:

  • Facility size
  • Number of locations
  • Number of processes and systems
  • Energy consumption
  • Audit level
  • Measurement requirements
  • Site-visit requirements
  • Complexity of operations
  • Reporting requirements
  • Technical expertise required
