Volume I is a complete and self-explanatory description of the National Energy Strategy inclusive of all information necessary to understand the development and justification of the Strategy. Volume II presents supplementary Background Material collected and analysed during the course of the project. Volume II consists of two parts: PART A (Sources and Methods) and PART B (Special Subsector Issues). PART A contains seven chapters. The subject of Chapter 1 is to integrate the material of this volume into the analytical approach as a whole and to give an outline of the tools applied in the Strategy development. Reference data provided in Chapter 2 summarizes the information as to the past energy consumption and the future economic development. Chapter 3 compiles basic parameters and assumptions with regard to energy forms, costs, the economic development as laid down for use in the project. Chapter 4 discusses in detail the projection of energy demand. Chapter 5 draws up the Projects under consideration. Chapter 6 presents key results of energy scenario computations, and Chapter 7 provides energy scenario indicators and assessment information. PART B of this Volume II contains full reporcs regarding topics, which have only briefly been addressed in Volume I. CONTENTS PAGE A SOURCES AND METHODS 7 1.

APPROACH 1.1 OVERVIEW The aim of the Strategy study is to determine the measures needed for modernising the Lithuanian energy system. The measures identified are referred to as Projects. Project Profiles specify the capital and time requirements for the implementation of the Projects and their expected effects on energy system performance. Twenty-four energy scenarios are established, from which the Energy Strategy in terms of a set of appropriately scheduled Projects can be derived. Each energy scenario comprises a demand scenario providing projections of the sectoral demands for final energy and a supply scenario presenting the required capacity installation and utilization levels of the energy production and conversion sectors for meeting the projected demands. The projection of the energy demands is described in more detail in Chapter 4. Sectoral consumption and energy intensity figures are derived from energy balance and consumption figures presented in Chapter 2.2, demographic data used are assembled in Chapter 3.2. For each demand scenario, a supply scenario is built so that: • the resulting capacity installation and operation schedules meet the sectoral final demands; • the scenario as a whole reflects the specific characteristics of the defined case. 1.2 APPLIED TOOLS: ENERGY TOOLBOX Of the various software tools offered by (ERM Energy's) Energy Toolbox (ETB), the Disaggregated Demand Analysis System (DDAS) is applied to the task of creating the demand projections, and the Reference Energy System (RES) is used for balancing the supply required for meeting demands under the conditions of the scenarios. The DDAS allows input, modelling, and projection of demand data, disaggregated as needed for use in the Strategy Study. It provides a computer-based environment for the organization of all the items of data for editing, debugging and solving the large number of scenarios, as under consideration in the Strategy Study, for instance. The environment is intended to mirror the structure of energy use of a given economy and is implemented as a pictorial representation displayed on-screen. Standard syntax equations are formulated specifically for this application. 1C CONSULT - ERM ENERGY - COWI CONSULT LITHUANIAN ENERGY INSTITUTE The RES simulates future energy supply for each scenario, for the years selected, and also calculates the cost of energy supply. Results are the primary supply of fuels, their processing, power generation, distribution to end-users, etc. Like the DDAS, RES allows for a user-defined disaggregation of all system components, ie the energy forms and the technologies under consideration. By its integration with the DDAS through a database and comprehensive data management facilities, the RES can directly access th~ annual demands calculated for a selected year for a scenario. Input and output information can be prepared in both printed and graph form. Energy balances and costs reports can be generated by the Report Generator.

REFERENCE DATA 2.1 MACROECONOMIC SCENARIOS (WORLD BANK, ME) Several economic scenarios have been developed by various institutions including the World Bank (WB) and the Lithuanian Ministry of Economics (ME). The common assumption of these scenarios consists in the flattening out of the economic slump experienced since the restitution of independence in 1990 during the years 1993 to 1994. The ensuing economic upturn varies from one scenario to the other as shown in Figure 2.1.1.
