India’s Power Transmission Network Crosses 5 Lakh Circuit Km

1. At a Glance

• India's inter-State + intra-State transmission network (220 kV and above) crossed 5 lakh circuit kilometres (ckm) on 14 January 2026, with cumulative transformation capacity of 1,407 GVA [1].
• It is the world's largest synchronous national grid ("One Nation–One Grid–One Frequency"), and the backbone for evacuating India's expanding non-fossil power to load centres [1][2].
• Examinable for GS-III (Infrastructure–Energy) and Prelims (numbers, voltage levels, agencies, Acts).

2. Why in the News

• Milestone crossed on 14 Jan 2026 with commissioning of a 628 ckm, 765 kV transmission line from Bhadla-II to Sikar-II substation (Rajasthan RE Zone), enabling evacuation of an additional 1,100 MW from Bhadla, Ramgarh & Fatehgarh solar complexes [1].
• 71.6 % growth since April 2014: addition of ~2.09 lakh ckm of lines and 876 GVA of transformation capacity [1].
• Ongoing projects targeting an additional 67,000 ckm to evacuate rising RE generation [1].

3. Background & Evolution

• Network expansion driven by the Electricity Act, 2003 (unbundling, open access) and the National Tariff Policy.
• 2013: Synchronisation of Southern Grid with NEW grid → "One Nation–One Grid–One Frequency" [2].
• CEA notified National Electricity Plan (Transmission) 2022-32 in May 2023, targeting 500 GW non-fossil by 2030 [3].
• Earlier PIB note (under PM Gati Shakti) projected 27,000 ckm + ₹75,000 cr addition by 2024-25 [2].

4. Core Static Facts

• Implementing Ministry: Ministry of Power; Planner: Central Electricity Authority (CEA); CTU: Power Grid Corporation of India Ltd (PGCIL) [1][3].
• Statutory base: Electricity Act, 2003; transmission planning under Section 73 (CEA functions).
• Voltage covered in 5 lakh ckm figure: 220 kV and above [1].
• Transformation capacity: 1,407 GVA (Jan 2026) [1].
• NEP 2022-32 targets: network → 6,48,000 ckm; transformation → 2,345 GVA; inter-regional capacity → 168 GW by 2032 (from ~119 GW) [3].
• Cross-border interconnections under plan: Nepal, Bhutan, Bangladesh, Myanmar, Sri Lanka; probable — Saudi Arabia, UAE [3].
• Inter-regional transfer capacity (2022 baseline): 1,12,250 MW [4].

5. Multi-Dimensional Analysis

Economic

• Lines enable evacuation from RE-rich but load-light states (Rajasthan, Gujarat) to demand centres, reducing curtailment losses [1].
• Investment vehicle: Tariff-Based Competitive Bidding (TBCB) for inter-State projects.

Environmental

• Supports 500 GW non-fossil by 2030 target; transmission is the binding constraint to RE integration [3].
• 765 kV lines lower per-MW carbon footprint of evacuation vs lower-voltage corridors.

Geopolitical / Strategic

• NEP envisages South Asia regional grid (BBIN + Sri Lanka, Myanmar) and OSOWOG / India–Middle East grid linkages with KSA, UAE [3].

Administrative / Federal

• Electricity is on the Concurrent List (Entry 38); transmission planning is centralised via CEA + CTU, but intra-State STUs retain network within states.
• Coordination bottleneck: RoW (Right of Way) clearances in forested / tribal areas remain a delay risk.

Scientific / Technological

• Shift to High Voltage Direct Current (HVDC) and 765 kV AC for bulk RE evacuation.
• Green Energy Corridors (Phase-I & II) financed partly via KfW (Germany) loans.

6. Recent Developments (last 12–18 months)

• 14 Jan 2026: 5 lakh ckm milestone via Bhadla-II–Sikar-II 765 kV line [1].
• 2025 Year-End Review (Ministry of Power) highlighted continuing build-out under NEP 2022-32 [3].
• CEA NEP (Transmission) 2022-32 published; 1,91,000 ckm and 1,270 GVA planned over the plan period (220 kV+) [3].

8. Mains Relevance

• GS-III: Infrastructure — Energy; Environment & Conservation (RE integration).
• Syllabus headings: "Infrastructure: Energy, Ports, Roads…" and "Conservation, environmental pollution and degradation".
• Question stems: 1. "Transmission, not generation, is now the binding constraint on India's 500 GW non-fossil target by 2030." Discuss. 2. "Evaluate the role of the National Electricity Plan (Transmission) 2022-32 in integrating renewable energy zones into the national grid." 3. "Discuss the strategic significance of cross-border grid interconnections under India's One Sun-One World-One Grid (OSOWOG) initiative."

10. Common Errors / Trap Areas

• 5 lakh ckm covers only 220 kV and above — not the total distribution network.
• The figure is circuit kilometres, not route kilometres (a double-circuit tower = 2 ckm per km).
• CEA ≠ CERC: CEA is the planner; CERC is the tariff regulator.
• Electricity is Concurrent List, not State or Union — common confusion.
• Bhadla-II–Sikar-II is 765 kV AC, not HVDC.
