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.
