Executive Summary The growth in electric energy use in Pakistan is expected to remain high for many years to come, and, by 2030, total demand is expected to increase by factors of between 5.6 to 8.2 times over the present year 2007 level i.e. 18,883 MW. This implies average annual growth rates of between 7.8% and 9.6% of the low and high scenarios of demand respectively. Demand for electric energy grew at an annual rate of 8.8% for the normal scenario during the period from 2007 to 2030. Many factors influence the load growth, and as these factors are difficult to predict, future load growth is potentially very variable, hence, needs review periodically. The longer-term forecast was based on historic relationships between past consumption, economic growth and number of customers. The study determined that there was a very significant potential to improve the efficiency of energy use through programs of DSM. Experience in other countries shows that important capital and operating cost savings for the electric sector can be obtained through DSM. This study recommends that Pakistan commit to an aggressive DSM program immediately. A forecast, including the potential impact of DSM, was prepared and is given in Table 3-19. The methodology employed in this report is multiple regression technique. The overall energy demand projections are achieved by summing the forecasted individual category-wise energy demands (i.e. Domestic, Commercial, Industrial, Agricultural, Traction, Street light and Bulk). The power demand is thereafter evaluated by adding appropriate losses and employing a suitable load factor on yearly basis. Three scenarios of the load forecast are illustrated graphically in the Figure below. Figure – 1

In the year 2030, under Normal scenario the forecast for Peak Demand is 1,13,695 MW, nearly 15.2 % higher than Low scenario (98,557 MW) and nearly 21.8 % lower than High scenario (1,45,304 MW). The three principal energy and demand forecasts for the country including KESC are summarized in the Table below. Table - 1

In addition to the above, an overview of load, losses and system demand for the three scenarios (Low, Normal, High) in the form of MW is depicted in tables Table-1(A), Table-1(B), Table1(C) receptively. The forecast can be used for generation planning, however, for transmission planning during the medium term period (2008-2014) PMS (Power Market Survey) forecast (Grid wise demand) would be advisable and appropriate to be referred, which is in process of development. It is important to note that in long term planning, a range of forecast is typically developed to bracket the expectations about higher and lower scenarios for load growth. The longer the forecast period, the greater is the uncertainty. However to reduce the uncertainty, it is recommended that Normal scenario should be considered as base case.

Introduction 1.1
Background
The power system planning broadly covers three segments of an electric power network namely Generation, Transmission and Distribution facilities. The developments in these sub-sectors whereas depend on many diverse parameters are also governed by the growth of economic parameters in domestic, commercial, agricultural and industrial sectors. The supply-side potential has to be assessed and developed to fulfil the demand side requirements, and side by side the interconnected system of transmission lines has to be developed to transmit the generated power to load centres. The load forecasting has always been the basis of additions of generation plants and transmission lines in any grid system. WAPDA was created in 1958 and at that time Pakistan was quite under developed and the total demand of WAPDA was around 100 MW. All along these years the country has been passing through different stages of development and the peak load met during 2006-07 was 14,941 MW. However a lot of hydro developments along upper Indus are yet to be carried out, indigenous coal resources are to be harnessed for power generation and import of power from neighbouring countries are options which may also be considered. This undoubtedly will involve huge expenditures which will necessitate least cost options to be adopted after assessing the future loads and developing a long range power plan to meet demand targets.
1.2
Strategy
The load forecasting is the fundamental element of power planning involving prediction of the future levels of power demand to serve as the basis for supply-side and demand side planning. Load forecasts are prepared for different time frames and level of detail. Generation planning requires a system level forecast of total generation requirements. Transmission and distribution planning requires far more load-levels and geographic details to assess the location, timing and loading of individual lines and transformation facilities. The load forecast is also used in demand-side management, revenue estimation and financial planning. The long-term forecast (2008 to 2030) presented in this report is based on a regression analysis of past consumption trends and relationships. The long range forecast is appropriate for generation planning. Segregation of the forecast into load centres and grid stations is based on PMS model considering developments in sub-sectors of industry, commerce, agriculture and domestic which have been taking place in a random fashion. In view of this an extensive data has to be collected for PMS model. Originally data used to be collected by PMS subdivisions and forwarded to divisional office in Lahore for final processing. The data collected for existing loads includes consumption by customer types defined as domestic, commercial, small industrial, large industrial, tube wells, public lighting and traction. Energy forecasts are computed for each consumption category at the sub-area level on the basis of trend analysis per customer sales including new developments in industrial, domestic and commercial sub-sectors. Industrial, commercial and domestic load forecasts include interviews, trend projections and a review of the applications for new and increased service. Customer growth factors, load factors, and diversity factors are applied separately to estimate the distribution of demand by grid station.
A detailed regression analysis involves the review of fundamental quantitative relationships in the electricity demand of Pakistan and the related independent variables in the data like electricity price, sectoral GDP, population etc. As historical load-shedding estimates are included in the data base, the resulting equations predict the energy that will be supplied if PEPCO system has no technical or supply constraints. This report provides detailed load forecast for PEPCO, KESC and Country for years from 2008 to 2030. The country level forecast has not been disaggregated at grid station level. It will be undertaken subsequently in the next step.

Historical Power System Supply And Demand Analysis 2.1 Supply Pattern Supply characteristics such as load shedding practices, auxiliary, transmission & distribution losses and the system load factor are essential ingredients needed to forecast generation as well as electricity demand requirements.
2.1.1 Load Shedding PEPCO and KESC systems are currently supply constrained in both capacity and transmission capability necessitating selective interruption of supply seasonally at peak and during off-peak periods as well. Load shedding will continue until sufficient additional capacity can be brought on line to recover suppressed demand and satisfy new growth. In the meantime several measures, in addition to capacity addition, are proposed and being implemented on an urgent basis to avert / mitigate the load shedding crises. Presently NPCC (National Power Control Centre) estimates the daily quantum of demand / energy deficit and DISCOs have the responsibility to implement the shedding as per criteria of distribution of rural / urban and priority feeders. A maximum quantum of 2,546 MW has been shed in year 2007. Following are the main reasons of load shedding:
Reasons of Load Shedding Sufficient generation capacity has not been added in the National Grid to meet the load requirements. Hydro capacity limitations due to water shortages in the reservoirs of Hydel plants during winter period Reduced gas quotas for thermal plants in winter due to increased consumption of gas in domestic sector. Generation capacity de-ration of old GENCO plants in summer due to weather conditions The forecasts developed in this report have accounted for load shedding. It is, therefore, assumed that the energy demand will be fully met. To that end, the sales data used in the regression, for example, has been adjusted to include an estimate of the energy shed. Thus, the sales figures reported here will tend to be higher than the actual level of sales reported in the “official” NTDC statistics publications.
2.1.2 Transmission and Distribution Losses During the 1980’s, WAPDA introduced programs to reduce power and energy losses throughout its system, the implementation of which proved to be quite fruitful. Present high level of system losses particularly distribution losses suggests that loss reduction efforts should continue to receive considerable attention in the near term in order to effectively reduce the cost of electricity to the customers. The following table contains a summary of energy generation, sale and auxiliary, transmission & distribution losses since 1997 for both PEPCO and KESC.

The figures indicate that PEPCO distribution losses dropped from 18 % to 14.6 % of gross generation during 1999 to 2007. In KESC, distribution losses are significantly high and range from 30.2% to 36.7% during the past 10 years.
2.1.3 System Load Factor The annual load factor depends to a high degree on the composition of loads on the system and how these loads vary seasonally. The load factors for PEPCO and KESC for the period 2002-2007 are tabulated below. These figures have been calculated on the basis of computed energy generation and computed peak demand for the two systems i.e. taking into account the load shedding and excluding import/export of electricity between PEPCO and KESC.

2.1.4 Demand Side Management Load forecasting must consider changes in both supply-side and demand-side efficiency as a power system expands over time. Supply-side efficiency is concerned with how well the technical and non-technical losses on the transmission and distribution system can be controlled, as well as the relative amount of generator station service consumption and equipment performance. The growing attention to demand-side efficiency is motivated by the cost effectiveness of demand-side management (DSM) in improving the system load factor, and its potential for reducing overall load growth, while maintaining acceptable levels of service.
Benefits of DSM Among the benefits are The potential for deferment or reduction of bulk transmission and generation investment leading to reduced capital cost. The deferment of tariff increases. The reduction of environmental impacts of generation. The decrease in the cost of power as a proportion of production cost in the economy. NTDC has the target to improve the load factor by employing the DSM techniques and by promoting the Industrial share in the composition of system load. It is expected that the load factor of the system shall improve to 71% provided the proposed DSM measures are implemented. The estimated impact of DSM on the load forecast has been considered in Chapter-3 in future projections.
2.2 Energy Share (Province Wise & Category Wise) PEPCO and KESC have detailed statistics on historical electricity sales and number of consumers for various electricity consuming sectors which capture the combined influence of the various factors underlying growth in electricity demand. Some of the salient features of this statistics are summarized in the following paragraphs. Energy Share in Sales (Province –wise) The province-wise share of energy sale for the year 2006-07 is shown below in the form of a pie chart.

Long-Term (Regression Based) Load Forecast
The long term forecast is determined through regression analysis of past energy consumption trends using a statistical data base for WAPDA and KESC system for the period 1970 to 2006 and other government publications and economic statistics. Following the Grid Code NTDC (clause PC 4.2 of the planning code), three scenarios low, normal and high have been developed considering economic & demographic factors and tariff etc.
3.1 Regression Methodology The forecasts of WAPDA and KESC sales by consumption category are determined by regression equations relating these sales to the growth in a number of independent variables. Regression analysis is concerned with describing and evaluating the relationship between a given variable (often called the explained or dependent variable) and one or more other variables (often called the explanatory or independent variables).
3.1.1 Parameters of Regression Dependent Variables (Y) • Electricity consumption (GWh) for various consumer categories including domestic, commercial, industrial and agriculture. Independent Variables (X) The potential independent variables (demographic and economic) for regression analysis included: •
Total GDP
•
GDP by major sector (agriculture, manufacturing, trade, services, etc.)
•
Electricity revenue per kWh sold by customer class (real price)
•
Number of customers by consumption category
Lag variables In many cases, dependence of variable Y (Dependent Variable) on another Variable X (Independent variable) is not instantaneous. Very often Y responds to X with a lapse of time. Such a lapse of time is called Lag. Dummy Variable Dependence of variable Y (Dependent Variable) is not only influenced by variables which can be quantified on some well defined scale (e.g., income, price, costs, etc.) but also by variables which are essentially qualitative in nature (e.g., sex, race, colour, Change in Government Policy, etc.). Such qualitative variables usually indicate presence or absence of a “quality” by assuming 0 and 1 value and are referred as dummy variables.
3.2 Regression Relationships Within the regression analysis, each of the independent variables (e.g. population, Gross Domestic Product, customers etc) was tested as an explanatory variable for the growth pattern in the dependent variable (Sales). For each combination of dependent and independent variables tested, the analysis calculates the least squares coefficient relating the variables and a number of measures (T-statistics, Minimum Mean Absolute Percentage Error (MAPE) and minimum probability) of the goodness-of-fit of the proposed equation. One equation was selected for each major consumption category (domestic, commercial, industrial and agriculture) for each utility (PEPCO and KESC). In general the equations were selected on the basis of the equation displaying the “bestfit” between the sales and the appropriate independent variable.
3.3 Elasticity Coefficients by Customer Class There are four elasticities corresponding to GDP, Real Price, Lag and Customers for each customer category Domestic, Commercial, Agriculture and Industrial as shown in Table 3-1.
3.3.1 Low, Normal and High Scenarios. The modified long term elasticity of each sector was gradually reduced or increased depending upon the scenario which is explained in detail in the Tables 3-2 to Table 3-4.
3.4 Projections of Independent Variables Projections of the key independent variables used in the long-term regression model are as under: GDP Growth by Sector (Country) Projected GDP growth rates used in preparing load forecast of energy demand are based on forecast prepared by planning commission. This economic forecast provides growth rates by economic sector. The regression equations which utilize income as an independent variable (GDP as a proxy variable for income) implicitly assume that historical income and electricity consumption ratio would be applicable in the future. Given the low relative levels of income measured in per capita terms and the fact that the per capita income would remain in a low band which characterizes developing countries of similar economic structure, it is assumed that income-to-energy consumption relationships will not change appreciable over the forecast period. The projections of GDP obtained from Planning & Development Division are presented in Table 3-5. Electricity Prices Real changes in future electricity prices will be determined by the cash flow requirements of the utilities, and this, in turn, will be dependent on the planned capital investment program. Until the investment program and related revenues are determined, it is not possible to estimate the impact on electricity sales of real price changes. In this load forecast, real price changes have been assumed to be zero, in line with historical tariff increases.
Domestic Customers The projection of population, domestic and agriculture customer are presented in Table 3-6. As far as population is concerned, its growth rate for the last three years was 1.9% and it is applied throughout the forecast period. The domestic customers are adjusted in order to capture the number of domestic customers present in a single bulk supply connection for a housing scheme. Electrified Households. In 1980 the electrified household percentage was 30% and in 1998 the electrified households were 70% as reported in the respective census reports. However, the percentage of electrified households is estimated to be 97% in the year 2030 as shown in Table 3-6. Agricultural Customers The average annual growth rate of last ten years is 3.39 % which has been used throughout the regression period as shown in Table 3-6.
3.5 Regression Results Once the growth rates in the independent variables (domestic & agricultural customers, category wise GDP, etc) are determined, the growth rates for the various consumption categories are readily calculated using the general equation for the regression analysis given below: Y T = YT-1 * (1+GR of G)b *(1+GR of R)C * (1+GR of L) d *(1+GR of C)e Where in the above equation Y
Represents electricity demand (Sales GWh)
GR
Represents Growth Rate
G, R, L,C
Represent independent variable (GDP, Real Price, Lag and Customers respectively)
T
Represents current year or time period,
T-1
Represents previous year or time period,
b, c, d, e
Represent elasticities of independent variables. (GDP, Real Price, Lag and Customers respectively)
The category-wise sale (GWh) forecast for the low, normal, and high scenarios of the country are shown in Table 3-7, Table 3-8 and Table 3-9 respectively with the categorywise sale (GWh) break up between PEPCO and KESC on the basis of historical share of each category for the last five years.
3.6 Generation Forecast In order to work out generation forecast from the energy sale, the important parameters are power system losses i.e. distribution losses, transmission losses, auxiliary consumption and load factor for PEPCO and KESC system. These are discussed as follows:
3.6.1 Projection of Losses PEPCO System The present level of PEPCO transmission losses is 6.6% and these losses have been gradually reduced to 3% from year 2007-08 up to the year 2017-18. Further these are kept constant for the rest of the forecast period. However the present level of distribution losses is 14.8%. These losses are reduced gradually upon 8% from the year 2007-08 to 2017-18, and then kept constant up to the year 2029-30. Auxiliary consumption in PEPCO system at present is 3.5% and is kept constant throughout the forecast period. These losses reduction pattern is presented in Tables 3-10 to 3-12.
KESC System Present level of transmission losses (2.5%) is kept constant throughout the forecast period. The distribution losses have been reduced gradually from 29.7% to 17.5% upto the year 2014-15 and then these are kept constant for the rest of the forecast period. Auxiliary consumption in KESC system is kept 4% constant throughout the forecast period. These are presented in Tables 3-13 to 3-15.
3.6.2 Projections of Load Factor PEPCO System The average load factor from the year 2001-02 to 2005-06 comes out to be 68.4% (Table 2-2). As per discussions in different meetings with Deputy Chief Energy Wing Planning & Development Division, acting Chief Energy Wing Planning & Development Division and Manager Generation Planning, the current load factor is kept constant (65.1%) for the next one years and after that it is increased upto 68% in the year 2013-14 and then it is kept constant for the rest of the forecast period. The projections of load factor for PEPCO are shown in Tables 3-10 to 3-12.
KESC System The base case load factor 73.6% is reduced gradually to 65% in the year 2020-21 and then it is kept constant for the rest of the forecast period as per decision in the meeting with Advisor to KESC on planning and energy. These projections are shown in Tables 3-13 to 3-15.
3.7 Forecast Results Based on the above system parameters, forecasts of computed energy sale, generation and peak demand have been developed for PEPCO, KESC and Country. Three scenarios, Low, Normal and High for PEPCO system, are shown in Table 3-10, Table 3-11 and Table 3-12 respectively. Three scenarios, Low, Normal and High for KESC system, are shown in Table 3-13, Table 3-14 and Table 3-15 respectively. Three scenarios, Low, Normal and High for the Country are shown in Table 3-16, Table 3-17 and Table 3-18 respectively.
3.8 Forecast with DSM The impact of DSM on the forecast considering a load factor improvement of 71%, with the proposed DSM measures, is presented year wise in Table 3-19.
3.9 Category Wise Composition of Loads (GWh Sales) The constitution of loads provides vital information to predict the shape of daily, monthly and annual load curves. The over all load factor of a system having greater percentage of domestic load is always less than a system having greater percentage of industrial load. In addition to this, the economic well being and financial status of a country is assessed from the constitution of loads i.e. what nature of industrial development is taking place in the country. In this connection, it is worth while to highlight the composition of loads at various intervals of the forecast period from 2008 to 2030 in the form of pie chart given in figure 3-1.

1. Elasticities for Domestic, Commercial, Industrial and Agriculture Sectors are assumed to decrease linearly to unity assuming saturation, by the year 2030. 2. The exercise has been conducted in consultation with Chief Economist, Planning & Development Division and Energy Wing,Planning Commission of Pakistan. 3. The decreasing pattern of elasticities was suggested by multiple regression analysis conducted for different time series and a similar study conducted by "Ms. Standard and Poors" ( McGraw Hills Study Division; A Study for Planning and Development Division, Pakistan). 4. GDP short term elasticities for the year 2005-06 and lag elasticities are taken from table 3-1. 5. The long term elasticities for the year 2005-06 are calculated using formula, Long term elasticity = short term elasticity / (1-lag elasticity) 6. The short term elasticities (2006-07 to 2029-30) are converted using the formula, short term elasticity = long term elasticity * (1- lag elasticity)
