CHAPTER-V

STUDY FOR SCOPE FOR USAGE OF RENEWABLE ENERGY

6.1 Installation of 10 kWp Solar PV Power Pack:

During the Audit, it was revealed that the College has ample space on the Terrace.

It is proposed to install a Standalone type Solar Photovoltaic Power pack of capacity 10 kWp.

The system will cater the Day load Demand of the College.

We furnish herewith the saving potential as under

No Particulars Value Unit

1 Installed Capacity of Solar PV Pack 10 kWp

2 Daily working period 6 Hrs./Day

3 Daily units generated 60 kWh/Day

4 Annual working days 280 Day/annum

5 Annual saving in Grid Electrical Energy 16800 kWh/annum

6 Annual CO2 saving potential 13.44 MT/Annum

7 Present Energy Charges 10 Rs/kWh

8 Annual monetary Gain 168000 Rs/Annum

9 Investment required 9,50,000 Rs lump sum



CHAPTER-VI

ENERGY CONSERVATION AND SAFETY PROPOSALS Following are the energy conservation opportunities are possible as per the detailed energy

audit. These energy conservation opportunities are of the type of no and low cost investment.

In the day time the voltage is on the higher side and the same needs to be reduced so

as to avoid premature failure of electrical appliances.

Proper load balancing to be done so as to avoid the neutral current being on the higher

side.

Excessive capacitance is to be reduced if possible a APFC can be installed.

The voltage harmonic is just within the limits and the current harmonics is on the higher

side and the same needs to be reduced.

Water management system must be in place. Reduction in water consumption by

addressing leakages of taps and other miscellaneous utilities. Installation of flow meters

which will help in reduction of water consumption. TOD can be implemented for pumping

application.

Rain water harvesting can be implemented for reducing pumping hours and ultimately

for saves in electrical energy.

Safety and protection like firefighting devices and electric relay can be used for Server

room. Flooring and rubber pad is required in the meter room. Roof top of the meter room

is not proper; it is required to fully cover from top. Danger signs are missing. Need to

provide sufficient light in the meter room.

MSEB transformer must be cordoned off.

Electrical cables must flow through cable tray.

Electrical single line diagram must be prepared.

Electricity distribution room must be complied with safety and protection. Fencing can be

used to the transformer and distribution room.

Firefighting device must be there in Electricity distribution room.

It is observed that poor illumination in some of the class rooms on ground floor. As per

requirement of sufficient illumination these tubes can be operated to save certain

amount of electricity and maintain required illumination.
