Power is the most vital input for the growth of any economy. Therefore, it is considered as a core industry as it facilitates development across various sectors, such as manufacturing, agriculture, commercial, industrial, educational, railways etc. Today's, modern culture always demanding for electrical energy. And day by day, the uses of electricity increases more and more. So meet this high power of demand there is need to generate more power. The only option is to meet the demand by increasing generation but, we are also lagging with the conventional sources so generating more power is also not convenient by convention ways. We will knows, the most of power plants are conventional. It is polluting earth’s atmosphere and the source of this conventional fuels are limited. Therefore we must have to turn at non-conventional power source.
India is the third largest producer of electricity in the world. India’s installed capacity stood at 288 GW as of 31-Jan-2016. The total generation has been recorded as 97.25 billion units as per CEA report on India Power Sector till Jan-16.
India posses a very large solar and wind energy potential which is seen as the huge energy resources for the future. India is endowed with abundant solar energy due to its convenient location near the equator. The solar power is going more popular because it is very simple to install and it can be located anywhere at sun rays easily available. It gives direct electrical power from sun rays. So it is very easy to use for ordinary people. Electricity generation from renewable sources will need to increase significantly to achieve the Sustainable Energy for all. The main consideration is the cost of solar power system and storage it. The position of the sun changes throughout the day and so changes the intensity of light falling on the fixed solar panels. Renewable energy is fact emerging as a major source of power in India. In a climate change conference as Paris in India, Indian PM expressed strong inclination towards solar energy. By 2030, India will reduce emission by 35% of 2005 levels, and 40% of its installed capacity will be from non-fossil fuels, he highlighted. Currently, India has a capacity of 4.8 GW solar power generation and a target of adding 100 GW solar power by 2022 has been set.
Renewable generation has the benefit of enhancing sustainability, reducing green house gas, reducing dependence on local or imported fossil fuels and increasing energy security through diversification of energy sources.
Although, the gap between power demand and generation has significantly reduced energy conversion in all sectors in the need of the hour. This case study focuses on the aspects of energy conservation in a sub-station by firstly reducing the consumption by replacing convention lights with more efficient LED lights. Secondly, the option of powering part sub-station load through clean solar energy is also evaluated. This meets multiple objectives including economics as well as environmental benefits for sustainable growth in line with the goals set at national level.
