What Happened
- Andhra Pradesh Power Generation Corporation (AP-Genco) has announced plans to develop two ultra mega thermal power plants, each with a capacity of 3,200 MW.
- The two plants would together add 6,400 MW of coal-based generation capacity to Andhra Pradesh's power grid, significantly boosting the state's energy security.
- The move comes amid Andhra Pradesh's growing industrial demand, driven by investments under the state's industrial corridor development and semiconductor manufacturing push.
- The plants are intended to ensure base-load power availability as AP pursues large-scale electrification targets and data centre investments.
- AP-Genco has been revitalising its energy sector with both traditional thermal and renewable energy additions.

Ultra Mega Power Projects (UMPPs): Policy and Framework
Ultra Mega Power Projects (UMPPs) are large-scale coal-based thermal power initiatives, each with a generation capacity of 4,000 MW or above, conceptualised by India's Ministry of Power in 2005-06 to rapidly expand electricity generation. UMPPs are designed to achieve economies of scale and deliver power at competitive tariffs. The Central Electricity Authority (CEA) acts as the technical partner, while Power Finance Corporation (PFC) is the nodal agency. Projects are awarded through tariff-based competitive bidding and implemented on a Build, Own, Operate (BOO) basis using supercritical technology.
- First batch of UMPPs: Sasan (Madhya Pradesh, 3,960 MW — Reliance), Mundra (Gujarat, 4,620 MW — Adani), Krishnapatnam (Andhra Pradesh, 4,000 MW — partially developed), Tilaiya (Jharkhand — cancelled).
- Supercritical technology used in UMPPs operates at higher steam temperatures and pressures, improving efficiency and reducing coal consumption and emissions per unit of electricity.
- Power Finance Corporation (PFC) incorporates Special Purpose Vehicles (SPVs) for each UMPP to manage the bidding process on behalf of beneficiary states.
- UMPPs are located either at coal pit-heads or coastal sites to minimize transmission losses and optimize fuel logistics.
Connection to this news: AP-Genco's planned 3,200 MW plants follow the ultra mega thermal model — large-scale, high-efficiency plants designed to serve as base-load anchors for state power grids.
State Electricity Boards and Gencos: Structure of India's Power Sector
India's power sector was restructured following the Electricity Act, 2003, which mandated the unbundling of vertically integrated State Electricity Boards (SEBs) into separate generation, transmission, and distribution companies. AP-Genco (Andhra Pradesh Power Generation Corporation) is the state generation utility responsible for producing electricity from thermal and hydro sources for distribution within Andhra Pradesh.
- The Electricity Act, 2003 is the principal legislation governing power generation, transmission, distribution, and trading in India.
- The Act ended the monopoly of SEBs, allowed open access, and enabled competition in generation and supply.
- As of 2024, India's installed electricity capacity exceeded 950 GW, with thermal (coal + gas) comprising approximately 57%, renewables ~42%, and nuclear ~1%.
- The Revamped Distribution Sector Scheme (RDSS), launched in 2021, aims to modernise distribution infrastructure and reduce Aggregate Technical and Commercial (AT&C) losses to 12-15%.
- State DISCOMs (distribution companies) are chronically loss-making; their aggregate losses were estimated at ₹6.5 lakh crore as of 2022-23 (UDAY scheme legacy).
Connection to this news: AP-Genco's thermal expansion is a state-government-led effort to ensure power security for industries and citizens, consistent with the post-2003 unbundled power sector structure.
Coal-Based Power vs. Energy Transition Tensions
India is committed to achieving 500 GW of non-fossil fuel capacity by 2030 and net-zero emissions by 2070 under its Nationally Determined Contributions (NDCs) submitted under the Paris Agreement. Yet coal remains central to India's base-load power supply, and new thermal capacity additions continue — particularly in states facing power deficits. This creates a tension between short-term energy security and long-term climate commitments.
- India is the world's third-largest emitter of CO2 and second-largest coal producer and consumer globally.
- India's coal-based installed capacity: approximately 236 GW (2024), generating over 70% of electricity by volume.
- The International Energy Agency (IEA) projects Indian coal demand to plateau by 2030 as renewable capacity accelerates.
- India's renewable energy capacity addition rate: approximately 20 GW/year as of 2024-25.
- India has committed to achieving 50% of cumulative electric power installed capacity from non-fossil fuels by 2030.
Connection to this news: AP-Genco's large thermal plant proposals reflect the energy security imperative that continues to drive coal capacity additions even as India accelerates renewables, particularly in states with high and rapidly growing industrial demand.
