PSU Companies in India: List of Top PSUs, Types, Sectors, Jobs & Status

Public Sector Undertakings (PSUs) are an important part of India's economy. These government-owned or government-controlled enterprises operate across oil and gas, banking, power, mining, defence, railways, engineering, infrastructure, finance and telecommunications.

India has several types of PSUs, ranging from large Maharatna enterprises to Navratna, Miniratna and other Central Public Sector Enterprises (CPSEs). Many of them are also major employers and play an important role in India's infrastructure and industrial development.

What Is a PSU Company?

PSU stands for Public Sector Undertaking. In simple terms, a PSU is an enterprise in which the government has ownership or control.

PSUs can be owned by:

• Central Government
• State Government
• Central and State Governments jointly

At the Central Government level, these enterprises are generally referred to as Central Public Sector Enterprises (CPSEs).

However, PSU and government company are not always legally identical terms. A government company has a specific definition under the Companies Act, while PSU is a broader term commonly used for public-sector enterprises.

Types of PSU Companies in India

Indian PSUs are commonly discussed according to their ownership and government classification.

1. Maharatna PSUs

Maharatna is the highest category of Central Public Sector Enterprises. Eligible companies receive greater financial and operational autonomy from the government.

Some well-known Maharatna PSUs include:

• Indian Oil Corporation
• ONGC
• NTPC
• Coal India
• Bharat Petroleum Corporation
• Hindustan Petroleum Corporation
• Power Grid Corporation of India
• GAIL
• Steel Authority of India
• Power Finance Corporation
• REC Limited

2. Navratna PSUs

Examples include:

• Bharat Electronics Limited
• Hindustan Aeronautics Limited
• NMDC
• National Aluminium Company
• Engineers India
• Container Corporation of India
• Rail Vikas Nigam
• RITES
• IRCON International
• National Fertilizers

3. Miniratna PSUs

Miniratna status is given to eligible CPSEs that meet specified performance and financial criteria.

They are divided into:

• Miniratna Category-I
• Miniratna Category-II

Examples include organisations such as RailTel, Cochin Shipyard and Airports Authority of India.

The classification of individual CPSEs can change as government policies and company performance change.
