Discuss the role of three services needed in supply of electricity. Should they be in different hands?

Following are three services needed in supply of electricity :
(i) Generation of electricity
(ii) Transmission of electricity
(iii) Distribution of electricity
All these services should be in different hands. Transmission of electricity should be in the hands of the government. The government and private sector may operate in the areas of generation of electricity and distribution of electricity. It would bring in more and more financial resources in power sector as well as competition.
