Concept:A public corporation is established mainly to provide essential services to the public rather than to earn profit.
Explanation:Public corporations are business organisations owned and controlled by the government.
They are created by an Act of Parliament or decree to deliver public utilities such as electricity, water, and transportation.
The central aim is to serve the welfare of the citizens with affordable and reliable services.
Although a public corporation may earn revenue and generate profit, profit is not its primary purpose.
Any surplus is usually reinvested to improve the quality of services.

It is also not set up to resolve administrative disputes, which is the role of courts and tribunals.
Therefore, the primary essence of a public corporation is to provide public utility services.
