In any industry, the three top operating expenses are often found to be an energy, labour and materials. If one were to find out the potential cost savings in each of the components, energy would invariably emerge at the top, and thus energy management function constitutes a strategic area for cost reduction.
Electrical energy is the most expensive and the most important form of purchased energy. For this reason, its use must be confined to a minimum for efficient and economic operation:
Because of its flexibility, electricity offers advantages over the conventional fossil fuels, and efforts to conserve electricity can result in significant cost savings.
Industries use a large amount of electrical energy, and that is why it is important to ensure a loss-free and energy-efficient system in industries.
In developing countries like India, where electrical energy resources are scarce and production of electricity is very costly, energy conservation studies are of great importance.
Energy audit is the translation of conservation ideas into realities by blending technically feasible solution with economic and other organizational considerations within a specified time frame. Energy conservation can be obtained by proper maintenance and operations.
An energy audit is a study of a plant or facility to determine how and where energy is used and to identify methods for energy savings.
Energy audits can mean different things to different individuals. The scope of an energy audit, the complexity of calculations, and the level of economic evaluation are all issues that may be handled differently by each individual auditor and should be defined prior to the beginning of any audit activities.
If we can reduce the energy usage or improve the energy efficiency in mechanical and electrical installations in a building, energy can be conserved and some of the resulting problems, such as greenhouse effect and ozone depletion can be alleviated.
Energy audit cannot be successfully carried out without the commitment from the top management. Management must be firstly convinced of the necessity of implementing energy management and hence energy audit.
Energy audit consists of several tasks, which can be carried out depending on the type of the audit and the size and the function of the audited facility.
Therefore, an energy audit is not a linear process and is rather iterative. The energy audit are carried out based on the following functional activities:
Lighting Audit - Walk-through survey: A walk-through audit was conducted during visits to assess the illumination requirement of the plant and scope of improvement of illumination quality and illumination level, with an objective of cutting down the electrical energy consumption and cost of electricity.
Power Load Audit - Motor load survey used in various processes: The energy consumption of the industry is identified in terms of the equipment and functional area wise. The results are obtained after measurements during the factory visits.
Harmonics Analysis: With the increased usage of non-linear electrical loads and automation in industrial units, poor power quality due to harmonic distortion has come up as a serious issue. To tackle the problem of increasing harmonic distortion in power distribution system, recently guidelines have been issued to various medium- and large-scale industrial units of the state to get voltage and current harmonic contents evaluated at their premises at the Point of Common Coupling (PCC) and undertake remedial filtering solutions, if required, for harmonic limits in excess of the limits.
