Some of the cases include incorporation of newer technologies which help in better control of energy usage. In a few of the observed cases it was recommended to adopt newer technologies for improved energy performance. Any cost implications of new technologies was suitably supported with quick RoI / payback of 9-12 months. In all cases the recommendations had a payback of lesser than 24 months as is accepted by majority of the Companies.
There are other common areas within every plant which could be explored for further energy saving which are as below.

With ever-rising grid tariffs, cost of basic energy (coal, oil, gas etc.) it definitely makes a strong business case for a plant to carry out Energy Audit. For plants which have never carried out energy audit there could be shocking revelations on this front. For plants which periodically carry out energy audit, this exercise helps in identifying niche areas for energy saving as well as keeping up the momentum.
While major energy saving lies in the process specific to a particular unit, the utilities present a generic energy saving opportunity for a plant. These energy saving opportunities are basically “low-hanging” fruits that can be used to capitalize on energy optimization by any plant – irrespective of it’s process or age or composition. By adopting few simple methods as outlined in the observations in the previous section, a plant can certainly expect to save some amount of energy., which is a welcome positive step. With additional measures the energy saving initiative could be taken up further.
Moreover a detailed energy audit reveals far more opportunities which can have a significant impact on a Company’s profit margins. Many companies are waking up to this fact and are adopting energy saving measures as a Company wide policy and not just as a one-time exercise. ISO 50001 is another step in that direction which indicates how well a Company is using it’s energy resources. Customers are satisfied in more than 90% of the cases wherein Energy Audit was carried out for the 1st time. Majority of these customers have vowed to carry out frequent and periodic energy audit to ensure maximum benefits and for maintaining continual momentum for energy saving within the plant.
