2. Overview
Instructor: Miss Masooma
Designation: Deputy Manager Trainee and Man Power Planning
Wapda
The Water and Power Development Authority (WAPDA) is a government-owned public
utility maintaining power and water in Pakistan, although it does not manage thermal power.
WAPDA includes Tarbela and Mangla dams among its resources. Its headquarters are in Lahore.
WAPDA was established in February 1959 to unify the maintenance of infrastructure previously
overseen by provincial agencies. Its Chairmen included outstanding civil servants like Ghulam
Ishaq Khan, Ghulam Faruque Khan and Aftab Ghulam Nabi Kazi who were
subsequently President of Pakistan, Minister for Commerce and Economic Adviser, respectively.
In October 2007, thermal power management was split into the newly formed Pakistan Electric
Power Company (PEPCO).
Debundding
If department is too large than debunding is needed. It provides the following things:
 Competition
 Management
 Service
 Performance
 Price control
Area Electricity Board in 1982, in which these distribution companies were named base on the
areas, like LESCO was known at that time as “Lahore Electricity Area Board”
Company Act
In 1994, according to Company Act, distribution companies were formed.
SECP (Security and Exchange Company)
In 1998, LESCO was registered with SECP

3. The ultimate goal was to privatize all these distribution companies
PEPCO
It is an independent company. And it has 9 companies under it. Recently another company which
covers tribal areas is came into being known as TESCO. These companies are given below:
 Peshawar
 Islamabad
 Gujranwala
 Lahore LESCO
 Faisalabad FESCO
 Multain MEPCO
 Sakhar
 Hyderabad
 Quetta QESCO
 Trible areas TESCO (tribal electric sully company)
Pepco basically has three different parts
1. GENCO
2. NTDC
3. Distribution companies

4. GENCO
All generation is under GENCO, which produces electricity and sold it to different
companies for distribution. It includes,
 GENCO 1
 GENCO 2
 GENCO 3
NTDC
National Transmission and Dispatch Company, it basially gets bulk power from GENCO.
In 2008, NTDC further sub divided the system.
500KV and 220KV it kept with itself and 132KV and below this voltage, the system was handed
over to DISCO’s.
LESCO
Lahore supply control
It is a distribution company and almost 100 grid stations are under it.
It has around 3 million users including:
Wapda
GENCO NTDC DISCO'S

5.  Industrial users
 Residential users
 Domestic users
 agriculture user
Basically there are four regions under LESCO, whose distribution is governed by LESCO
 Lahore region
 Okara region
 Kasoor region
 Sheikhupura region
Mission Statement of LESCO
 Un interrupted power supply
 Quality service
 Customer care
Area of Operation
 Lahore
 Okara

 Sheikhupura
Types of PD under LESCO
There are three types of PD under LESCO
 PD Construction
 PD Civil
 PD GSC
Organization Structure
 BOD
 CO
 Marketing
 HR
 Customer Service

6.  Managing Department
 Internal Audit Department
 External Audit Department
Internal Audit Department
It checks whether policies are followed or not.
It also check what are the discrepancies in the system.
On this basis, different reports are generated according to the situation, known as:
 Advanced Para
 Summary Para
 Draft Para
External Audit Department
PAC (Public Account Commission)
Opposition Leader is head of this commission. This commission overlooks the
system and find flaws in it. If there is any discrepancy, a warning is given. And it
give opportunity to solve the issue, which is known as “Advanced Para”
If the issue is not solved than a file is generated and forwarded to high authorities
known as “Draft Para”
Operation Department
This is the most important department and distribution is under it
Offices
There are two main offices
 Head Office
 Circle Office
Circle Office
Circle office is under operation director equivalent to Chief Engineer.

7. Areas
LESCO is divided into seven areas (Circles)
Lahore is portioned into four circles
 East Circle
 South Circle
 West Circle
 Central Circle
In each circle “Supredendant Engineer” sit over there. Transformer failure, D-issue these all are
under his work.

11.  Forecasting (Power Market Survey)
 Line forecasting
 Load Forecasting
 Load forecasting can be handled in two ways.
 New grid station
 Old grid station either by Augment or by Extent
 Daily problem
 Issues
 Tender evaluation Committee
Projects are floated and this committee basically checks which companies are responsive
and which are non-responsive
Minimum Area for Grid Station: 18-20 canal
40 to 50 crore is needed approximately, to build grid station
Whenever load increases more than 5MV for single user, than it’s the rule that they are needed to
bulid their own grid station.
Transformer Rating: 13MVA, 26MVA, 40MVA
PMS Unit:
This is basically an important section of Planning and Schedule. Its work include following things:
 Future Load in this area
 Load Flow studies (Software work)
Through this PC-1 report is generated.PMU do only this. PC-2,PC-3, PC-4 these reports
are generated on later stages.
 Cost
 Cost Benefit ratio
 Payback period
 Approval
 Head Quarter (Chief executive)
 BOD
 Ministry
 Secretary of Water and Power resources

12. 2. Precruitment
Whenever public money is involved, there is a process known as “Precurement”.
There are some rules introduced by PPRA, that must be obeyed during procurement.
Precurement has severeal advantages that are listed below:
 Competitive environment
 Transparency
 Accountability
In procurement “Brands (company names)” are not specified, only specification of
the things are mentioned.
It includes,
 Number of transformers
 Number of lines or conductors
 Towers
There are basically two resoures:
 LESCO own resources
 World Bank, Asian Development (ADP) resources
The process is followed as:
 Tender float
 If equipment is in store, no need to tender
 Whenever company is selected by the process of tendring, equipment is supervised
 Buy equipment
 “Contract Document” of every project
3. Finance
This department basically deals with loan.
 Initially 10% pay
 Two types of projects
 LESCO own revenue
These project are supervised by PDGSE (Project Director GSE)
 Loan from World Bank(head office in New York), Asian Development (ADP)
(head office in Monala)
These projects are supervised by LESCO and also by ADP
ADP gave loan in installations known as Tranch 1, Tranch 2, Tranch 3, Tranch4

13. Own Revenue Ways:
 Ascar account (Billing)
 Deposit work
 Capital contribution e.g. Meter cost
Types of Payments by LESCO
A. Direct payment
Like payment to PEL. The steps for this payment are as followed:
 Withdrawal application
 Bill copy
 Inspection Certificate
 Performance Guarantee
 GRN
 Nonpayment certificate
 Tax deduction
In this payment there is usually a guarantee of 18 months or 24 months
B. Payment through LC (Letter of Credit)
The steps for this payment are as followed:
 Firm invoice (Bank Alfalah, Sindh Bank, Standard Charter Bank)
 PU copy
 ADP gives to bank and Bank gives to Firm
C. Payment through Advance (Empress)
We get money in advance. But this method has the disadvantage of “Interest”.
Although money is not spend on project and still is present in Bank, the interest is
going to start from the first day on the total amount that is took in advance.
D. Disbursement through Re-imbursement
Use money our self
Quantity Rate Liquid and
Damages
FBR Net amount A/C

14. due to late
(LD)
LD can be maximum 10% of the total.

4. Environmental unit
The important factors that must be considered and should be controlled are:
 Air noise
 Water testing
Environment Impact Analysis (EIA)
Initial Environment Examination (IEE)
 After study the report is sent to Ministry of Environment (EPD)
 PC1 (5 years) is generated, for this actually EIA is compulsory
 This is sent to Ministry of Environment, which issues the NOC (set of clauses), which
need to be implement.
 Binding document is prepared
 Environment Monitory Plan is prepared
