AVAILABILITY AND QUALITY OF POWER SUPPLY

1. At a Glance

• India has transitioned from a power-deficit to a power-sufficient nation, with 520.51 GW of installed generation capacity as on Jan 2026 [S1][S2].
• Electricity is a Concurrent List subject — generation, transmission and distribution responsibilities are shared between the Union and States [S1].
• Quality issues (voltage fluctuation, interruptions, AT&C losses) are now the binding constraint, more than raw generation deficit [S1][S3].

2. Why in the News

• Ministry of Power PIB release dated 12 March 2026 stated installed capacity at 520.51 GW with 296.388 GW added since April 2014 [S1].
• India met all-time peak demand of ~256 GW without shortage; FY 2025-26 max demand met was 242.49 GW [S4][S2].
• Energy-supplied vs energy-requirement gap fell from 0.5% (FY23) to ~NIL in 2025-26; peak shortage from 4.0% to ~NIL [S2].

3. Background & Evolution

• Electricity Act, 2003 — unified statutory framework replacing 1910/1948/1998 Acts.
• DDUGJY (2014) — rural feeder separation; IPDS (2014) — urban distribution.
• UDAY (2015) — DISCOM financial turnaround.
• Saubhagya (2017) — household electrification.
• RDSS (2021) — Revamped Distribution Sector Scheme replacing IPDS+DDUGJY; outlay ₹3.03 lakh crore [S3].
• 296.388 GW capacity added between Apr 2014 and Jan 2026 [S1].

4. Core Static Facts

• Implementing Ministry: Ministry of Power (Union); MNRE for renewables [S1].
• Constitutional locus: Electricity — Entry 38, Concurrent List (Schedule VII) [S1].
• Installed capacity (31.01.2026): 520,511 MW — fossil 248,542 MW (47.7%) + non-fossil 271,969 MW (52.3%) [S5].
• RDSS outlay: ~₹3.03 lakh crore; projects sanctioned ~₹2.8 lakh crore [S3].
• Smart meters installed under RDSS (15 Jan 2026): 4.05 crore [S3].
• AT&C losses: down from 21.91% (FY21) to 15.04% (FY25) [S3].
• Capacity added (Apr 2014 – Jan 2026): 296.388 GW [S1].
• FY 2025-26 capacity addition: ~65 GW (record) [S2].

5. Multi-Dimensional Analysis

Economic - Reliable power is precondition for PLI / Make in India / Viksit Bharat 2047 manufacturing push [S1]. - DISCOM losses (AT&C 15.04%) remain fiscal drag on State exchequers [S3].

Administrative / Federal - Concurrent subject — Centre funds RDSS but DISCOMs are State-owned; outcomes depend on State action [S1][S3]. - Marginal supply gaps attributed to State T&D constraints, not generation [S1].

Environmental - Non-fossil share crossed 50% of installed capacity (52.3%) — aligned with NDC target of 50% non-fossil capacity by 2030 [S5].

Scientific / Technological - Smart metering (4.05 cr installed) enables prepaid billing, demand response, ToD tariffs [S3]. - Diverse generation mix (thermal + hydro + nuclear + RE) used to meet peak [S2].

Social - Saubhagya achieved near-universal household electrification; focus now on 24x7 quality supply, especially rural [S1].

6. Recent Developments (last 12-18 months)

• 9 June 2025: Peak demand of 241 GW met with zero shortage [S4].
• FY 2025-26: All-time peak ~256 GW met without shortage [S4].
• 12 March 2026 PIB: Ministry of Power confirmed 520.51 GW installed capacity, supply gap near-zero [S1].
• Jan 2026: 4.05 crore smart meters under RDSS [S3].
• FY25: AT&C losses fell to 15.04% (from 21.91% in FY21) [S3].

• Smart meters installed under RDSS (Jan 2026): 4.05 crore [S3].
• All-time peak demand met FY26: ~256 GW [S4].
• Electricity = Concurrent List, Entry 38 [S1].
• Energy supply gap FY26: ~0.03% / NIL (vs 0.5% in FY23) [S2].
• Schemes replaced by RDSS: IPDS + DDUGJY [S3].
• Statutory basis: Electricity Act, 2003 [S1].

8. Mains Relevance

• GS-III — Infrastructure: Energy; Indian Economy & Mobilisation of Resources.
• Syllabus heading: "Infrastructure: Energy, Ports, Roads, Airports, Railways etc."
• Possible stems: 1. "India's power sector has shifted from a generation-deficit to a distribution-deficit story. Examine in light of RDSS." (250 words) 2. "Despite achieving record installed capacity, quality of power supply remains uneven across States. Discuss the structural causes." 3. "Evaluate the role of smart metering and AT&C loss reduction in financial revival of DISCOMs."

10. Common Errors / Trap Areas

• Electricity is Concurrent, not State or Union — often mis-marked.
• RDSS ≠ R-APDRP; RDSS launched 2021, subsumed DDUGJY+IPDS (not UDAY).
• "Installed capacity" (520 GW) ≠ "peak demand met" (~256 GW) ≠ "actual generation."
• MNRE handles renewables, but RDSS is under Ministry of Power.
• Saubhagya = household connections, NOT 24x7 supply guarantee.
• Non-fossil installed capacity crossing 50% ≠ 50% of electricity generated (still fossil-dominated).
