650 KW SOLAR PV PLANT IN LAKSHMIBAI NATIONAL INSTITUTE OF PHYSICAL EDUCATION GWALIOR (LNIPE):
The Lakshmibai National Institute of Physical Education (LNIPE) is a Government of India deemed university situated in Gwalior under the Ministry of Youth Affairs and Sports. It is MP’s largest solar rooftop project installed.
The university required a solar plant to be installed, as the cost which it was initially incurring on power, was extremely high. In order to minimize the cost it resorted to solar power generation. Also their top floor was getting heated up daily so the best alternative to shield it was to install solar plant so as to avoid the direct heat.
Statcon Energiaa as per their requirements set up a 650 KW Pure Grid Tied Solar PV Power Plant which would lead to maximum power generation with the help of solar energy at peak hours and it automatically led to reduction in their costs incurred in power consumption by nearly one third.

The plant’s capacity and mechanism can be explained by net metering. In simple words it is a billing mechanism through which consumers who produce some part or the entire part of the electricity can benefit from their electricity anytime rather than at the time at which it is generated. For example, if a residential customer has a PV system on their roof, it may generate more electricity than the home uses during daylight hours. If the home is net-metered, the electricity meter will run “backwards” (not literally) to provide a credit against what electricity is consumed at night or other periods when the home’s electricity use exceeds the system’s output. Customers are only billed for their “net” energy use.

Now as it is evident that from the details that the cost incurred by the university on the power was reduced by one third amount and the plant’s performance and efficiency was also certified thereby.
As it is seen that the technology used has a significant CAPEX, but in the later years the return on investment will be between 3-4 years, thereby decreasing the cost incurred by the consumers on the electricity consumption per unit. Thus the expenditure is reduced to a great extent and simultaneously it can be used in some other productive use for the expansion of its profits.
