Introduction
Energy is the foundation of modern civilization and the key driver of economic development. From industrial production to agriculture, from transportation to communication, and from domestic use to national security — energy plays a critical role in every aspect of life. In India, energy is not only an essential infrastructure component but also a strategic sector that determines the pace of socio-economic growth.
India’s power sector has evolved significantly over the decades, transitioning from energy shortages and inefficiencies to ambitious plans for renewable integration, sustainability, and universal electricity access. The government has set a vision of achieving “Power for All” and making India a global leader in clean and green energy.
Definition of Power and Energy
Energy refers to the capacity to do work. It can exist in various forms — thermal, electrical, chemical, mechanical, solar, and nuclear.
Power is the rate at which energy is produced, transmitted, or consumed. In India, the power sector primarily deals with the generation, transmission, and distribution of electricity derived from multiple energy sources such as coal, hydro, gas, nuclear, solar, and wind.
Historical Development of the Power Sector in India
- Pre-Independence Period:
During the colonial era, power generation was localized, serving limited industrial and urban needs. The first electric supply company was established in Kolkata in 1897. - Post-Independence Period:
The government recognized electricity as a key input for development. Major initiatives were taken through the Five-Year Plans to establish State Electricity Boards (SEBs), hydroelectric projects, and thermal power stations. - Reforms Era (1990s onwards):
The introduction of liberalization and privatization policies opened the sector to private participation. Reforms such as the Electricity Act, 2003, the establishment of the Central Electricity Regulatory Commission (CERC), and initiatives like UDAY (Ujwal DISCOM Assurance Yojana) transformed the sector.
Structure of the Power Sector
The Indian power sector comprises three main segments:
- Generation: Production of electricity using various energy sources.
- Transmission: Transfer of bulk power from generating units to substations.
- Distribution: Delivery of power from substations to end consumers.
Each segment involves both public and private entities, with regulation and coordination provided by central and state-level agencies.
Sources of Energy in India
India’s energy mix is diversified and includes both conventional and non-conventional sources.
1. Thermal Power
- Dominant source, accounting for around 55–60% of total installed capacity.
