Advantages and Disadvantages of Diesel Power Station
Advantages of diesel power station :
- It can be installed at the load centre.
- It can be started in short time and can take up load immediately.
- Its layout design and construction are simple.
- Space required for installation is less, hence cost of land is less.
- Number of accessories required is less, the number is further reduced if similar units are installed, this reduces the cost of spares.
- Water required for cooling purpose is less.
- Overall efficiency is high.
- The plants are comparatively neat and dean as compared with thermal power plants.
- Number of skilled staff required is less.
- The overall cost per kW of installed capacity is less in comparison to thermal power station.

- The fuel used being diesel, cost is more and required to be imported from other countries which increases running cost of diesel power station.
- Overload capacity of such stations is limited, and they cannot work under overload condition for long period.
- Generating capacity of such plants is limited, as target capacity plants cannot be installed due to high cost of fuel.
- Cost of lubricant is more and repair of engines etc. cost more.
