Perform Achieve and Trade (PAT) is an innovative programme of Bureau of Energy Efficiency under the National Mission for Enhanced Energy Efficiency (NMEEE) in National Action Plan on Climate Change (NAPCC). PAT Scheme is aimed at improving the energy efficiency in energy-intensive sectors. PAT is a market-based mechanism to enhance the cost-effectiveness through certification of excess energy saving which can be traded.

The participation in PAT Scheme is mandatory for Designated Consumers under Energy Conservation Act 2010 (ECA). The aluminium, cement, Chor-Alkali, fertilizer, iron and steel, pulp and paper, textile industries and thermal power plants, Railways, DISCOM and Hotels currently coming under Designated Consumers accounts for over 60% of India’s total primary energy consumption. The PAT Scheme has set energy efficiency targets for these energy-intensive consumers. Under the PAT Scheme, the Designated Consumers must reduce their Specific Energy Consumption within a period of three years. Those who fail to achieve the target will have to pay penalty. Consumers exceeding the PAT target SEC value is eligible for Energy Saving Certificates (ESCert) which can be traded and used for compliance purposes.

Typically, PAT Cycle includes

  • Designated Consumer Notification
  • Data collection and verification
  • Consultation
  • Ministerial technical committee and notification
  • Implementation
  • Achievement verification and ESCert Trading

With every PAT cycle, new sectors are added and the number of energy-intensive consumers coming under the title Designated Consumers is increasing. As of now, PAT Cycle-1 (478 Units, 2012-13 to 2014-15) has been concluded. PAT Cycle-2 (621 Units, 2016-17 to 2018-19) and PAT Cycle-3 (737 Units, 2017-18 to 2019-20) are going on. To widen the PAT scheme, PAT Cycle 4 (917 units in 2018) has been initiated by BEE, which added hotels for the first time along with new units in the existing sector under the PAT Scheme.

What We Do

Mandatory Energy Audit

Our experienced team of BEE Accredited Energy Auditors and energy professionals can conduct Mandatory Energy Audit and prepare the Mandatory Energy Audit Report which needs to be submitted to State Designated Agency (SDA) and BEE. Mandatory Energy Audit is carried out as per BEE notification and guidelines. The onsite audit is followed by submission of Mandatory Energy Audit Report as per BEE guidelines and format which includes Energy Conservation Measures, baseline data, operating parameters, techno-commercial analysis etc. Our accredited energy auditor can help you to file Form 1, Form 2 and Form 3 as part of the PAT requirement.

PAT Advisory Services

We can provide full support in achieving the energy savings projected during Mandatory Energy Audit. A continuous energy savings assurance study conducted in your plant over a period can help you achieve the targeted Specific Energy Consumption. We are also providing documentation support and training for the plant personnel on PAT compliance requirement or related activities. Our experience in conducting PAT baseline audits, Mandatory energy audit, M&V Audit since PAT cycle I will help you to achieve your targets and prepare the necessary documents for PAT.

Aditya Energy Services (AES) has successfully carried out both Mandatory Energy Audit and Measurement & Verification studies under the PAT scheme of BEE. Few names of the Designated Consumers (DCs) served by us are: Gujarat State Fertilizers Limited (GSFC, Vadodara); JK Paper Mills Limited (JKPM – Rayagada, Odisha); ITC Limited (Bhadrachalam and Tribeni, Kolkata); Alok Industries Limited (Vapi, Gujarat); Chemplast Sanmar Limited (Karaikal and Mettur facilities); India Cements Limited ( 7 nos. plants spread across Tamilnadu, AP and Telangana)……

Energy Audit

Energy Audit means the verification, monitoring and analysis of the use of energy including submission of technical report containing recommendations for improving energy efficiency with cost-benefit analysis and an action plan to reduce energy consumption. Other than energy concern, the energy audit also helps in reducing fossil-fuel consumption and emission of harmful gases. An improvement in energy efficiency within your organization can potentially bring significant business benefits. With a focus on energy efficiency, we are providing energy audit services to help our clients in reducing energy consumption and energy cost. We are committed to giving the most promising solutions that improve energy efficiency and bring sustainability. Energy audit services are a key part of our dedicated energy efficiency services and the first step towards comprehensive energy management strategy of any organization.

We employ a systematic approach that goes beyond equipment efficiencies and estimates the overall system efficiencies of important processes and supporting utilities. This approach helps identify inefficiencies and hidden losses that may exist due to the design philosophy, system design, existing equipment design and/or operating practices.

Our energy audit:

  • Establishes a energy consumption baseline using monthly energy usage
  • Evaluates the energy consumption of various equipment’s/machines
  • Power and fuel assessment study
  • Compressed air system study
  • Identifies ways to enhance operational efficiency and decrease maintenance costs
  • Resolves occupant comfort issues.
  • Identifies economically feasible ECMs

The output of energy audit is a technical report containing

  • Detailed view of the current energy consumption pattern
  • Performance evaluation, heat balance and identification of losses.
  • Identify opportunities and create solutions to reduce energy use and hence energy cost.
  • Financial analysis of each solution (Payback period or ROI)


Detailed evaluation of plant/facility. Measurement of operating parameters of Electrical (Electricity bill, Transformers, Motors, DG sets, Lighting …), Mechanical (Pumps, Fans, Blowers, Chillers, AHUs, Air Compressors…) and Thermal systems (Boiler, Ovens, Heat Recovery Units, Dryers …).
