### Key Business & Strategic Takeaways
1. **Energy Transition is Real:** Non-fossil fuel sources now constitute the **majority (52.3%)** of India’s installed capacity, signaling a permanent shift in the energy mix.
2. **Solar is the Growth Engine:** Solar has overtaken wind and hydro to become the single largest renewable source, with explosive growth in generation over the past five years. This confirms solar as the primary focus for future power investments.
3. **Grid Stability is High:** The data shows that energy supply meets demand with negligible deficit at the national level, indicating a robust transmission and distribution network. Power cuts are more about local distribution issues than a lack of overall generation.
4. **Rural-Urban Gap Narrows:** The high average hours of supply (22.6 hours in rural areas) demonstrate significant progress in rural electrification and reliability, creating new opportunities for productive use of electricity in rural economies.

### Detailed Breakdown by Question
#### (a) & (b) Installed Capacity and Actual Power Generation
This section provides a comprehensive view of India’s power infrastructure and its utilization.
**Installed Capacity (As of January 2026): Total = 5,20,511 MW**
– **Non-Fossil Fuel Dominates:** For the first time, non-fossil sources (Renewables including Hydro + Nuclear) account for a majority share at **52.3%** (2,71,969 MW), compared to Fossil Fuels at **47.7%** (2,48,542 MW).
– **Solar’s Leading Role:** Within the non-fossil mix, Solar PV is the star performer with **1,40,602 MW**, making up **27%** of the total national capacity. This dwarfs Wind (10.5%) and Hydro (9.8%).
– **Coal Still Key but Share Declining:** While coal remains the single largest fuel source at 42.5% (2,21,210 MW), its share in the total mix is now below 50%.
**Actual Power Generation (2020-21 to 2025-26 up to Jan’26)**
| Fuel Source | Generation in 2025-26 (MUs)* | Key Trend |
| :— | :— | :— |
| **Thermal (Coal, Gas, etc.)** | 10,79,911.61 | Consistent growth, remains the backbone of baseline power. |
| **Large Hydro** | 1,50,039.12 | Generation fluctuates based on monsoon, but remains a crucial balancing power source. |
| **Nuclear** | 45,193.67 | Stable and growing contributor to the clean energy mix. |
| **Solar** | **1,38,386.93** | **Explosive growth.** Generation has more than doubled in five years (from ~60,000 MUs in 2020-21). This reflects the massive capacity additions. |
| **Wind** | 95,586.95 | Strong and steady growth, almost doubling generation in five years. |
| **GRAND TOTAL** | **15,41,236.14** | Total generation for the period, excluding imports from Bhutan. |
*MUs = Million Units
#### (c) State-wise Power Supply Situation (April 2025 – January 2026)
The data indicates a highly reliable power supply across the country, with a national energy deficit of effectively **0.0%**.
– **Top Performing States (Zero Deficit):** Chandigarh, Delhi, Gujarat, Rajasthan, Goa, and most Northeastern states supplied 100% of their energy requirement.
– **States with Marginal Deficit:** While most states have a deficit of less than 0.1%, the highest *volume* of unsupplied energy was in **Delhi (8 MUs)** , **Maharashtra (9 MUs)** , and **Tamil Nadu (10 MUs)** . This is attributed to local transmission/distribution constraints, not a shortage of power.
– **Notable Exception:** The Andaman & Nicobar Islands had a deficit of 5.2% (18 MUs unsupplied), indicating unique challenges for island grids.
#### (d) Average Daily Power Supply (Up to December 2025)
– **Urban Areas:** **23.4 hours** per day.
– **Rural Areas:** **22.6 hours** per day.
The high and nearly equal hours of supply in both rural and urban areas demonstrate the significant success of government initiatives like *Saubhagya* and the ongoing efforts to strengthen distribution infrastructure. The marginal difference of less than one hour shows a major improvement in rural power reliability.
