1.EPC

Engineering Procurement Construction

Commonly adopted by private companies

Turnkey contract

EPC provides:

A single point responsibility

A fixed contract price

A fixed completion date

Performance guarantees

Page 4: EPC+Energy audit of reliance infrastructure

WHY EPC ..?

Competency

Control

Marketplace

Priorities

1. Maintaining budget

2. Maintaining schedule

3. Establishing and maintaining quality

In EPC contract both parties agrees on the standards with regards to the design and engineering, construction, procurement, testing, commissioning, check and acceptance of which details of the specification from an integral part of the contract.

Page 6: EPC+Energy audit of reliance infrastructure

EPC CONTRACTING

Single point responsibility.

A fixed programme with a date certain for delivery

A fixed price

Guaranteed performance and reliability level.

Tripartite (or direct) agreement between the funder

and each member of the supply chain.

Example : BTG ( Boiler Turbine Generator )

Page 8: EPC+Energy audit of reliance infrastructure

KEY CONDITIONS FOR EPC CONTRACT

Identifying the risk profile and allocating risk.

Price and payment

Time and delay LDs.

Performance guarantees and performance LDs.

Variations to the works.

Defects in the works.

Caps on liabilities.

Page 9: EPC+Energy audit of reliance infrastructure

SPLIT EPC

Split an EPC contract into two or more separate

contracts.

Advantages for split EPC contracts

• Create a tax effective structure.

(onshore and offshore projects )

• Reflect a different risk profile.

o Drawback

• No single point of responsibility.

ENERGY AUDIT

An inspection, survey and analysis of energy flows

in a building, process or system with the objective

of understanding the energy dynamics of the

system under study.

TYPES OF ENERGY AUDITS

PROPOSALS FOR ENERGY REDUCTION

Zero Investment Required

Medium Investment Required

High Investment Required

Page 25: EPC+Energy audit of reliance infrastructure

ZERO INVESTMENT REQUIRED

SAVINGS INCASE OF COMPUTERS

PERIPHERALS

Power consumed by 1 systems ( LCD's )

= .31 units / hr

Power consumed by 1 system( CRT )

= .376 units / hr

Page 26: EPC+Energy audit of reliance infrastructure

SAVINGS

It was observed that during lunch break from 1:00

pm to 2:00 pm if the systems are switched off then

there is a scope of lot of power saving

Let us take 200 CRT and 100 LCDs are switched off

by the employees while going for lunch

Then Savings =

( .31 * 100 + .376 * 200 ) * 4 = Rs 531 per day

Savings per month = Rs 531 * 28 = Rs 14,868.

Page 27: EPC+Energy audit of reliance infrastructure

SAVINGS IN CASE OF CPU

If 300 CPU are switched off for an hour from 1:00

pm to 2 :00 pm

Then Power saved for 300 CPU’s = 300* .627

= 188.1 units

Saving in cost = Rs 5. * 188.1 = Rs 940.50 / day

Monthly saving = Rs 940.50 * 28 = Rs 26334

Net saving = 26334 + 14868 = Rs 41202 / month

While in power saving mode the system uses 15 %

of the real power

So real savings = 15 * 41202 /100

= Rs 6180.30 /month/ building

Page 28: EPC+Energy audit of reliance infrastructure

AC SAVINGS

In canteen it was observed that all the four 2 TR

split AC of sector 24 building works from 9 am to 6

pm while mainly it is need for only lunch hour, so

making the working of AC in canteen from 12 pm to

3 pm

Savings per day = 1.35 * 4* 2*4 = 43.2 units

Saving per month = 43.2 * 4 * 28= Rs 4838/month

(The multification factor for converting in electrical

power is 1.35KW/1 TR )

Page 29: EPC+Energy audit of reliance infrastructure

OTHER FACTORS THAT CAN CONSIDERED

The current working temperature of A.C = 24

degree Celsius

According to ECBC (energy conservation building

code) , the ambient working temperature of Air

Conditioning should be between 26-27 degree

Celsius.

Each 1 degree C temperature rise will lead to

saving of 2% to 3% energy .

Page 30: EPC+Energy audit of reliance infrastructure

OTHER FACTORS THAT CAN CONSIDERED

Proper use of blinds (chicks) through windows to

utilize natural light.

Encourage people not to use lift especially for one

or two floors.

Replacing air conditioners after every 7 years.

Considering the annual operating cost and the

deterioration in performance.

Page 31: EPC+Energy audit of reliance infrastructure

MEDIUM INVESTMENT REQUIRED

Use of electronic ballast

Change of 36 W T-8 tubes with 28 W T-5 tubes.

Page 32: EPC+Energy audit of reliance infrastructure

USE OF ELECTRONIC BALLAST

Total working hours per year = 3720 hrs

Units consumed by normal choke = 3720 / 18

= 206.67 units

Total Cost = 206.67 * 4= Rs 826.68 per year

Units consumed by Electronic choke = 3720 / 33

= 112.72

Total Cost = 112.72 * 4 = Rs 450.88 per year.

Difference = Rs (826.68 – 450.88) = Rs 375.80

( Normal choke consumes about 1 unit of electricity when used for 18 hours. While Electronic Choke consumes same 1 unit of electricity when used for 33 hours. )

Page 33: EPC+Energy audit of reliance infrastructure

USE OF ELECTRONIC BALLAST

Using 612 electronic chokes can save

=Rs 375*612 per year. = Rs 2.29,989.60

Cost of 1 T-5 28 W Electronic choke of Philips =

Rs 500 = 500 * 612 = Rs 306000

Payback period = 30600 / 222989.60

= 1.3722 years

Page 34: EPC+Energy audit of reliance infrastructure

CHANGE OF 36 W T-8 TUBES WITH 28 W T-5

TUBES.

Page 35: EPC+Energy audit of reliance infrastructure

CHANGE OF 36 W T-8 TUBES WITH 28 W T-5

TUBES.

T-8 36 W initial rated output = 2950 lumens

T-5 28 W initial rated output = 2900 lumens

Total no. of tubes in sector- 24 = 612

System usage per day = 9 hrs

System usage per year (310 days) = 2790 hrs

Total energy consumption for 36 W tube per year

= (36*27900*612) / 1000

= 614692.8 Kw hr

Page 36: EPC+Energy audit of reliance infrastructure

CHANGE OF 36 W T-8 TUBES WITH 28 W T-5

TUBES.

Cost per unit = Rs 4.

Total cost = Rs 61462.8 * 4 = Rs 2458771.2

Total energy consumption for 28 W tube per year

= (28*27900*612)/1000 = 478094.4 Kw hr

Cost per unit = Rs 4

Total cost = Rs 4 * 478094.4 = Rs 1912377.60

Difference (Rs) = (2458771.20-1912377.60)

= Rs 546393.60 per year

Page 37: EPC+Energy audit of reliance infrastructure

CALCULATION OF PAY BACK PERIOD BY REPLACING

OF T-8 TUBES BY T-5

No. of tubes to be changed = 612

Cost of each tube with fittings comes out to be Rs

600

So total Investment = Rs 600 * 612 = Rs 367200

Saving per year = Rs 546393.60

Payback Period = 1.4879 years

Page 38: EPC+Energy audit of reliance infrastructure

HIGH INVESTMENT COST

1.TERRACE GARDEN

A well-designed rooftop garden can provide several

benefits, including reduced energy use, reduced

urban heat effect, reduced storm water

runoff, better air quality and increased green space

In summers the terrace garden can reduce the Air

conditioning bill of top by approximately 20 %.

Page 39: EPC+Energy audit of reliance infrastructure

TERRACE GARDEN

Estimated Area of the terrace of sector – 24

building , Noida = 900 square metre

Estimated cost of building terrace garden = Rs

100 per square foot

(Source:http://money.outlookindia.com/article.aspx?8

7109.)

Roof top area = 900 sq. metre

= 900 * 10.763 911 square = 9687.5199 sq. feet

Total cost of building a terrace garden

= Rs 9687.5199 * 100 = Rs 968751.99

Page 40: EPC+Energy audit of reliance infrastructure

TERRACE GARDEN

Air conditioning systems at 6th floor of sector 24 building Noida

2 * 7.5 TR + 4 TR= 19 TR

Now working of these ACs from 9 am to 6 pm will consume total unit in a month = 19 * 1.35 * 9 * 28 = 6463.8 units

Total cost = 6463.8 * 4 = Rs 25855.2

If 20 % of reduction is achieved from terrace gardening through ACs bill

Then saving per month = Rs .20 * 25855.2 = Rs 5171 per month

Suppose ACs work for 6 month in a year

So total cost saved = Rs 6 * 5171 = Rs 31026 / year.
