Audit : Energy Audit is a systematic approach to identify Energy Wastages in various process/ equipments through Mass Balance and Energy Balance and to determine how this Energy Wastages can be minimized with in a stipulated time and reasonable cost.
The Need for Energy
Auditing : The increasing global trade liberalization and growing global competition have made productive improvement, including Energy Cost reduction, an important bench mark for economic success. Under this scenario, it is imperative that Energy Utilization be optimized. It includes improving the
Energy Generation, Transmission & Distribution and Efficient
End Use of Energy.
The primary objective of an Energy Audit is to determine ways to reduce the specific Energy consumption.
Therefore, the extent and type of Energy Audit should results in gains commensurate with the effort made.
Types of Energy Audit:
Preliminary Energy Audit
are carried out on the basis of visual observation, analysis of data provided by plant personnel, Log sheets and measurements from the instruments present on panel board. The objective of preliminary energy audit is to identify the energy conservation opportunities, where Detailed Energy audit can be carried out.
Detailed Energy Audit
are to identify specific Recommendations/ Suggestions/ Proposals for energy savings and formulation of action plans for the implementation of the recommendations based on the investment required, payback period, cost- benefit ratio, etc.
Gather and collect information in specially designed, “Energy systems Questionnaires” format, for the industry under study.
Inter- and intra- industry comparison of the collected data.
Assessment of the present efficiency index for energy consumption in the industry/ process.
Data/information regarding energy consumption vis-à-vis production for the past three to five years (on a monthly basis) should be analyzed to arrive at the specific energy consumption figure.
In-depth study of the plant operations, equipments and systems for a general review of the energy systems to assess the operational efficiency and potential for economization.
Evaluating detailed recommendations for energy saving / Conservation.
Formulation of detailed action plans/ strategies in consultation with the plant management for the implementation of the identified energy saving measures.
Training the operating personnel in the specifics of Energy Conservation to enable them to implement the recommendations and also to monitor the progress on a periodic basis.
