ENPEP is a set of micro-computer based energy planning tools that are designed to provide an integrated analysis capability. ENPEP begins with a macroeconomic analysis, develops an energy demand forecast based on this analysis, carries out an integrated supply/demand analysis for the entire energy system, evaluates the electric system component of the energy system in detail, and determines the impacts of alternative configurations. Also, it explicitly considers the impacts the power system has on the rest of the energy system and on the economy as a whole.
- Base year energy balance - user selected level of detail;
- Base year energy prices;
- Energy technology performance;
- Energy technology costs;
- International energy price projections;
- Electric system load characteristics;
- Local environmental coefficients - optional.
Local, regional, national scales possible.
1. Short (1-3 years) to long-term (50 years maximum).
2. Annual time steps in Total Energy.
3. Annual, seasonal, monthly in Detailed Electric System Analysis.
- Energy policy analysis;
- Energy tariff development;
- Energy project investment analysis;
- Electric system expansion planning;
- Environmental policy analysis (for energy system).
Macroeconomic analysis
No macroeconomic model. Provides interface to external macroeconomic model(s).Total energy system analysis
Demand analysis: Detailed evaluation of composition of demand by sector, subsector, fuel, useful energy. Growth of demand determined by macroeconomic variables and/or other user-specified parameters. Energy conservation and demand side management analysis capabilities;Detailed electric system analysis
Resource analysis: Representation of depletable resource availability and cost; Representation of renewable resource availability and cost;
Supply side analysis: Detailed evaluation of supply system configuration, both current and future. User-defined structure and level of detail;
Supply/demand balance: Non-linear, equilibrium solution for total energy system. Energy policy constraints can be imposed.
Load curve: Computed from total energy system analysis or input separately by user;Environmental analysis
Load characterization: Analysis of historical load data to develop hourly, seasonal and annual load characteristics;
Generation expansion analysis: Least cost optimization of system expansion plan (WASP III plus).
All environmental burdens computed as uncontrolled emissions, with alternative control equipment, under alternative environmental regulations, and with incremental cost of control.
Air-pollution: Treatment of main pollutants possible;
Water: Treatment of all pollutants and water consumption possible;
Solid waste: Treatment of all waste streams possible;
Land use: Treatment of facility land use and operational land requirements;
Occupational health and safety: Treatment of construction and operation illness, injury, fatalities.
Decision support analysis: Prototype decision making analysis module being developed.
Flexibility
Energy system structure and data input are adaptable to local conditions. Can be expanded with data development.
Future development
Continuing improvements in computational algorithms and features; development of graphical user interface; and development of Windows version. Development of an electricity system expansion analysis module WASP IV which handles fuel, generation and heat limitations, and environmental regulation constraints.
User friendliness
Menu-driven, on-line help, error checking, graphic outputs; Graphical user interface under development.
Documentation
User manual, technical description available in English.
Training
3-4 weeks for Total Energy System Analysis;
3-4 weeks for Detailed Electric System Analysis;
Annual courses provided by IAEA; occasional courses provided by U.S. Department of Energy, US Agency for International Development, World Bank.
Case studies
Over 400 individuals from 60 countries have received formal training at Argonne on one or more ENPEP modules. In addition, IAEA has offered several regional courses on WASP III plus (ENPEP version). Also, several short courses (one to three weeks) on one or more ENPEP modules (e.g. BALANCE and IMPACTS) have been provided as part of particular projects. Case studies with one or more ENPEP modules have been conducted in many countries. Recent applications include: Malaysia, China, Colombia, Indonesia, Nepal, Turkey, Romania, Peru and the United States.
Hardware
