Energy Audit – An Overview

Energy Audit is the first step in Energy Conservation and Energy Efficiency Projects for Industrial Plants. Energy Audit is a periodic exercise undertaken by a plant to assess its energy consumption and identify opportunities for Energy Conservation and Energy Efficiency. It also helps plant personnel in modernizing the plant with new technological solutions. It benefits plants cut down production costs.

In India, Energy Audit is quite popular in an Industrial or Commercial Facility. Many companies have realized the potential of energy saving in their plant. However one must realize that Energy Audit is only the first step in the direction of energy efficiency and energy conservation. The recommendations made as part of the energy audit have to be implemented to achieve the energy saving targets.

The energy saving recommendations doesn’t require much investment. In some high cases, the investment may be higher. The plant then takes up the investments in a phase-wise manner, which result in delayed energy saving for the plant. In fact the plant may never take some of the recommendations up. This renders the entire energy audit exercise futile.

Energy Audit works for every single Plant or Commercial Facility, as there is always scope for Energy Optimization through Energy Conservation & Energy Efficiency. Every plant goes through some changes over a period of time. Moreover an external Energy Audit team works across departments and brings in rich experience gained from Energy Audit of several plants. This not only results in gaining fresh perspective of Energy saving possibility by an external team also results in bench-marking based on similar parameters.

Energy Audit gives a positive orientation to Preventive Maintenance, Safety and Quality Control programs thereby improving the overall efficiency and output of existing system.

Nearly all the Industrial Units and Commercial Complexes have a potential to save 10-15% on Energy Bills and additional savings in Thermal Energy.

The evident reason why a plant goes for an Energy Audit is the saving of energy. This saving translates into monetary saving and hence can have a direct impact on profitability of a Company. It is also a step towards sustainability.

However, Energy Audits should look at a more comprehensive approach than just reducing cost. Industries should focus more on reducing their carbon footprint as necessitated by Governing Environmental Laws. Energy Audits must go beyond the conventional approach and adopt newer technologies for Green Power Generation.

With increased environmental awareness the pressure on Industries is mounting to reduce their Carbon footprint by adopting Greener Methods wherever possible. In such as scenario Energy Audit would play a crucial role in offering Industries a comprehensive approach towards a Greener Plant.

There is no specific answer as to how much energy a plant could save post an Energy Audit. An estimate could certainly be provided and in all cases Energy Audit could prove to be useful and economically viable. This is especially true in the present day scenario when Energy costs are ever rising and are expected to rise further.

Each Industrial Plant must carry out Energy Audits for reducing their energy usage by adopting energy conservation and energy efficiency measures.
