On the supply side energy management system, self generation in key energy-intensive industries in India which ranges from 50 to 100 per cent of the total power consumption plays a vital role in energy solutions. There are also small commercial entities that deploy back-up power units to compensate for grid power shortages. Large industrial users typically benefit from lower unit costs arising from economies of scale in self-generation. For small entities the advantages lie in business continuity from back-up power. Such local generation solutions not only ensure reliable power supply but also avoid system losses in transmission and distribution network and eventually save on electric bills.

Not all the solutions suggested above on 'how to save on energy bill' require huge investments but needs development of an investment plan to achieve energy efficiency where ever necessary. Measures such as installation of VFDs, optimizing voltage and frequencies of own generation and fine-tuning of existing pumps and motors involve very low levels of investment that are capable of generating high levels of energy and financial savings. These measures are especially advantageous for the large numbers of small firms that have limited capital to invest in expensive energy management program.
