Non-fossil share of power capacity

Topic: Energy Resources of India: Conventional and Non-conventional · NCERT: Beyond NCERT

Meaning

The non-fossil share of power capacity is the part of a country's total installed electricity capacity (the most power all its plants can produce, measured in GW) that comes from plants that do not burn coal, oil or gas. These are solar, wind, hydro, biomass and nuclear plants. It matters because India's updated NDC uses this share as a climate target. India crossed 50 per cent in June 2025, five years ahead of the 2030 deadline [1][2]. However, coal still produces about three-quarters of the electricity India actually uses.

Explanation

What is counted

• Non-fossil capacity includes:
• solar and wind, which change with the time of day and the weather;
• hydro, which depends on water in rivers and reservoirs;
• biomass, which burns plant and farm waste rather than fossil fuel;

• nuclear, which is non-fossil but is not renewable.

• Fossil capacity means coal, oil and gas plants.

• The share is worked out like this: non-fossil capacity ÷ total installed capacity × 100.
• On 30 September 2025, India's total installed capacity was 500.89 GW. Non-fossil sources made up 256.09 GW of this, which is over 51 per cent [1].
• Within the non-fossil total, solar was 127.33 GW and wind was 53.12 GW [1].

Capacity is not generation

• Installed capacity is the most power plants can produce, measured in GW.
• Generation is the electricity plants actually produce, measured in units (kWh).
• Why the two shares differ:
• Solar works only during the day.
• Wind is strong in some seasons and weak in others.
• A coal plant can run day and night.

• So 1 GW of coal produces far more electricity in a year than 1 GW of solar.

• Result: the non-fossil share of capacity is above 50 per cent, but coal still produces about three-quarters of India's electricity (2024-25). The non-fossil share of generation has not reached 50 per cent.

• One exception, for a short time: on 29 July 2025, renewables met 51.5 per cent of a 203 GW demand. Solar supplied 44.50 GW, wind 29.89 GW and hydro 30.29 GW [1]. This was one day. It was not the share for the whole year.

The targets and how India reached the goal

• Updated NDC (2022): an NDC (Nationally Determined Contribution) is a country's own climate pledge under the Paris Agreement. India's updated NDC has two key targets:
• 50 per cent of installed power capacity from non-fossil sources by 2030;

• a 45 per cent cut in emission intensity of GDP (greenhouse gas released for each rupee of GDP) from the 2005 level by 2030.

• Other targets:

• 500 GW of non-fossil capacity by 2030.

• Net zero by 2070, announced at COP26, Glasgow (2021) as part of the "Panchamrit" (five nectar elements) pledges. Net zero means India's emissions will be balanced by the amount removed from the air.

• How fast new capacity is being added: in April–September 2025 (FY 2025-26), India added 28 GW of non-fossil capacity and only 5.1 GW of fossil capacity [1].

• What helps make capacity useful:
• transmission lines, which carry power from sunny and windy states to cities;
• battery storage and pumped hydro, which store daytime solar power for use at night.

Where it occurs

• India, whole country: the share is measured for India's total installed capacity. The 50 per cent mark was crossed in June 2025 [1][2], and total capacity passed 500 GW on 30 September 2025 [1].
• States rich in renewables: most new solar and wind capacity is in Rajasthan, Gujarat, Tamil Nadu and Karnataka, along with Andhra Pradesh, Maharashtra, Madhya Pradesh and Himachal Pradesh. The Green Energy Corridor (GEC, 2015) carries their power to the national grid. It is run by MNRE, POWERGRID and state transmission companies.
• Ladakh, at Pang: GEC Phase-II (Cabinet approval October 2023) plans 13 GW of renewable capacity with a 12 GWh Battery Energy Storage System [3]. Pang lies on a high, cold desert plateau with strong sunshine and thin air [3].
• Coal belt (where fossil capacity is concentrated): Jharkhand (Dhanbad, Bokaro), Chhattisgarh (Korba) and Odisha (Talcher, Ib Valley). These regions are the most affected as the non-fossil share grows.
• World: the NDC target comes from the Paris Agreement. India's net-zero year was announced at COP26, Glasgow (2021).

Don't confuse with

• Non-fossil share of generation: this measures electricity actually produced (kWh), not capacity (GW). Capacity has crossed 50 per cent, but coal still produces about three-quarters of the electricity.
• Renewable share: nuclear is non-fossil but not renewable. The NDC target is for non-fossil capacity, which counts nuclear as well.
• Emission intensity target: this is a separate NDC goal. It is a 45 per cent cut in emissions per unit of GDP from the 2005 level by 2030. It is not a cut in total (absolute) emissions, and it is not a capacity share.
• 500 GW non-fossil target vs 500 GW total capacity: India's total installed capacity crossed 500 GW (500.89 GW) on 30 September 2025 [1]. The target of 500 GW of non-fossil capacity is for 2030. Non-fossil capacity then stood at 256.09 GW [1].

Prelims Hooks

• India crossed 50 per cent non-fossil share of installed capacity in June 2025, five years before the NDC deadline of 2030 [1][2].
• 30 September 2025: total capacity was 500.89 GW, of which non-fossil was 256.09 GW (over 51 per cent). Solar was 127.33 GW and wind 53.12 GW [1].
• Trap: the 50 per cent goal is for capacity, not generation. Coal still produces about three-quarters of India's electricity (2024-25).
• Updated NDC (2022): 50 per cent non-fossil capacity by 2030, and a 45 per cent cut in emission intensity (not absolute emissions) from the 2005 base year. Net zero is by 2070, not 2050.
• Non-fossil = solar + wind + hydro + biomass + nuclear. Nuclear counts as non-fossil even though it is not renewable.
• April–September 2025: 28 GW of non-fossil capacity was added, against 5.1 GW of fossil capacity [1].

Mains Points

• Capacity–generation gap (GS-III):
• India met its 50 per cent non-fossil capacity goal five years early [1][2], but coal still produces about three-quarters of its electricity.
• Causes: solar and wind rise and fall with time of day and season, storage is limited, and transmission is weak.

• Responses: Green Energy Corridors, battery storage (12 GWh at Pang, Ladakh [3]), pumped hydro, and cross-border grids under OSOWOG.

• Regional effects of a rising non-fossil share:

• New capacity is concentrated in western and southern states (Rajasthan, Gujarat, Tamil Nadu, Karnataka). Power from these states must travel long distances to cities.
• The eastern coal belt (Jharkhand, Chhattisgarh, Odisha) faces job losses and falling royalty income. Railways also stand to lose freight income from coal.
• This calls for a just energy transition (moving away from coal in a way that is fair to the people and regions that depend on it). It needs reskilling, new industries and reuse of mine land.

• India gets no JETP finance, so it must pay for this through its own policies.

• Next steps beyond the capacity target:

• Reach 500 GW of non-fossil capacity by 2030.
• Raise the non-fossil share of generation, not just capacity.
• Meet the 45 per cent emission intensity cut and the 2070 net-zero goal.
