Description of the Project:

In order to maintain the temperature of the all control

rooms of Power Plants, VAM was installed. Whenever

VAM is out of service, the temperature in control

rooms was maintained by operating package AC units

of respective plants. For operation of package AC unit,

the role of cooling water pressure is vital. To maintain

the cooling water pressure for U-2 AC unit and U-3 AC

unit we are forced to run two Booster Pumps of

capacity 37.5 kW and 45 kW Action Taken:

A team consisting of bottom level supervisors was

formed with a objective of running the AC Units with

less power.

After the study, the team came with an idea that by

providing one 0.75 kW booster pump in the U-2 ACW

line, the cooling water pressure requirement of both

the AC Units can be maintained by running only 37.5

kW ACW pump. The same is implemented after

management approval.

Solar Power Harnessing

The sun provides a tremendous resource for

generating clean and sustainable electricity without

toxic pollution or global warming emissions

Recognizing the importance of solar energy, NBV

harnessing solar energy in following ways:

• Installing solar water heaters at guest house and

Bachelor hostel

• Utilising passive sun lighting at applicable areas in

the plant

• Installation of 2 no of NoriKool double glazed

transparent sheet resulted in saving of 960 Units.

• Construction of office / club building with Eco

Friendly lighting
