- 1. Gujarat Power Engineering And Research Institute. Topic : Comparison Between Steam, Hydro, Diesel & Nuclear Power Plant Prepared by :-Patel Ravi(131040109051)Guided by: Prof. Hema Mehta
- 2. 1) By Initial Cost & Running cost Power Station Initial Cost Running cost Steam power Plant lower than those of Hydro & Nuclear. Higher than hydro & nuclear. Hydro Power Plant very high because of dam construction. Practically NIL; no fuel needed Diesel Power Plant Lowest compared to all other power stations. Highest due to Diesel prices. Nuclear Power Plant Highest due to complex nuclear reactors. Second lowest
- 3. 2) By Location & Space required Power Station Location Space required Steam power Plant Where there is ample supply of water and coal. Needs sufficient space for all equipment. Hydro Power Plant Where large reservoirs can be obtained by dam construction. Needs very large space for constructing a dam Diesel Power Plant Where there is required space & water, thus can be located anywhere. Needs very little space for all equipment Nuclear Power Plant Where there is enough supply of water, but must not be too far away from populated areas. Needs the least space, compared any other power station of equal capacity
- 4. 3)By Overal Efficiency & Stand-by losses Power Station Efficiency Losses Steam power Plant This is plant is ≈ 25% efficient. This is due to Boiler remaining in operation even if turbine is switched off. Hydro Power Plant This is plant is ≈ 85% efficient. This Plant has no stand-by losses Diesel Power Plant This is plant is ≈ 35% efficient. This Plant has lesser stand-by losses Nuclear Power Plant This is plant is ≈ 55% efficient This Plant has less stand-by losses
- 5. 4)By Limit of source of power Power Station Limit of source of power Steam power Plant Has most Limited fuel Reserves. Hydro Power Plant Has undependable water source due to weather variations. Diesel Power Plant Has Limited fuel Reserves. Nuclear Power Plant Has sufficient fuel Reserves.
- 6. 5) By Cost of Fuel & Clean emissions Power Station Cost of Fuel Justification Clean emissions Justification Steam power Plant Maximum, due to constant demand of coal & transportation. Has highest polluting emissions. Hydro Power Plant Practically nil. Practically no emission Diesel Power Plant Higher than Hydro and Nuclear power stations. Has cleaner emissions compared to steam & nuclear power stations. Nuclear Power Plant Minimum, due to small quantities of fuel required. Has cleaner emissions compared to steam power stations but produces nuclear waste, which is currently an unsolved problem.
- 7. 6) By Maintenance costs Power Station Maintenance costs Justification Steam power Plant High. Skilled staff required. Hydro Power Plant Lowest. Diesel Power Plant Low. Nuclear Power Plant Highest. Highly skilled and specialised staff required.
- 8. 7) By Transmission & Distribution costs Power Station Transmission & Distribution costs Justification Steam power Plant Low. Plant is close to load center. Hydro Power Plant Highest. Plant is furthest from load center. Diesel Power Plant Lowest. Plant is at load center. Nuclear Power Plant High. Plant is far from load center.
- 9. 8) By Starting Power Station Starting Justification Steam power Plant Longest starting time. Hydro Power Plant Shortest starting time. Diesel Power Plant Short starting time. Nuclear Power Plant Long starting time.
