MAJOR PARAMETER DECISIONS
The major parameter decisions that must be made for any new electric power-generating plant or unit include the choices of energy source (fuel), type of generation system, unit and plant rating, and plant site. These decisions must be based upon a number of technical, economic, and environmental factors that are to a large extent interrelated (see Table 8.1). Evaluate the parameters for a new power-generating plant or unit.
| Parameter | Some alternatives |
|---|---|
| Energy source or fuel | Common fossil fuels (coal, oil, and natural gas) Nuclear fuels (uranium and thorium) Elevated water (hydroelectric) Geothermal steam Other renewable, advanced technology, or nonconventional sources |
| Generation system type | Steam-cycle (e.g., steam-turbine) systems (with or without cogeneration team for district heating and industrial steam loads) Hydroelectric systems Combustion-turbine (e.g., gas-turbine) systems Combined-cycle (i.e., combined steam- and gas-turbine) systems Internal-combustion engine (e.g., diesel) systems Advanced technology or nonconventional sources |
| Unit and plant rating | Capable of serving the current expected maximum electrical load and providing some spinning reserve for reliability and future load growth considerations Capable of serving only the expected maximum electrical load (e.g., peaking unit) Capable of serving most of the expected maximum load (e.g., using conservation or load management to eliminate the load that exceeds generation capacity) |
| Plant site | Near electrical load Near fuel source Near water source (water availability) Near existing electrical transmission system Near existing transportation system Near or on existing electrical-generation plant site |
