This document outlines a proposed energy management system project to reduce electricity consumption and bills. It discusses Pakistan's energy crisis due to increasing demand and stagnant supply. The project aims to decrease consumption by managing loads through automation rather than increasing generation. A pilot will be conducted at PNEC to record current wastage and evaluate savings from the system. Block diagrams and a task flow are presented, with the project divided into modular phases and progress reported over time.

5. PROJECT TITLE
Design an Energy Management System
to manage electricity consumption
and reducing electricity bills.

6. PRESENTATION CONTENTS

8. The Problem(s)
We live in a country where energy
shortage is huge problem
With every increasing day the demand of
electricity is increasing and
Unfortunately the generation is at a
standstill
As a result the shortfall for power is
increasing every day

9. Energy crisis in Pakistan worsens
day by day.

Primary Problem
Problem
Overloading Of The Increased bills due to
Power Grid electricity wastage.

11. The Approach to solve the problem
There are two ways to solve the problem.
• requires large investments
Increased and government
Generation initiative, which are currently
nonexistent.
Decreased • limiting the wastage of
energy during operation of
consumption equipment

12. An analysis of existent reduced
consumption schemes.

difference energy is like institutions or

13. Our Scheme
• Overcome the human error
in energy wasted during
turning loads on and off
We • For example in classrooms
intend to where there is a set routine
to turn the loads on and off
• Or offices where there are
set times for load usage.

14. Let us take the example of PNEC
We wish to carry out the practical experiment in PNEC
• Since PNEC is an institution where loads are scheduled
• But it has been seen that electricity is wasted between the periods and in free periods
• Hence we plan to record the usage of electric energy for some time.
• Then install our system and record the results
• We have evaluated the amount of electricity wasted in PNEC in one month
• These are only calculations and evaluations the correct view will only come when we
implement a recording system

15. A Rough Analysis Of Wasted Energy.
• The total load per class is 40*6 + 60*6 = 600 W or . 6kW
• It is observed the energy wasted for 2 hrs. then 2 *.6 = 1.2 kWh
• 1.2 kWh * 24 * 5 * 4 = 576 kWh
• .6 * 24 * 5 * 4 * 5 = 1440 kWh
• total energy 576 + 1440 = 2016
• Wasted energy = 576 / 2016 = .28
• Which makes 28 % energy conservation.

16. Hence.
• It is our aim to test the project in a section of PNEC at least.
• Then display the result of the saved energy
• Compare it with proposed saved energy
• The result will be used to further enhance the boundaries of our
project into a product.
