- MH = Tarapur (first) | RJ = Rawatbhata | TN = Kalpakkam + Kudankulam
- GJ = Kakrapar | UP = Narora | KA = Kaiga | AP = Kovvada (proposed)
🚨 EXAM TRAP
- First nuclear plant = Tarapur (Maharashtra) — NOT Kalpakkam
- Nuclear father India = Dr. Homi J. Bhabha (NOT Sarabhai)
- Tamil Nadu has TWO nuclear plants: Kalpakkam + Kudankulam
- Kovvada = proposed (NOT yet operational)
- Thermal = 60–65% (HIGHEST share) | Nuclear = only 8.8 GW

-
Jharia = largest bituminous coal region in India
- Major coal areas: Jharia, Bokaro, Karnpura, Chandrapura, Giridih, Rajmahal
- Gondwana coal = 98% of India's coal production
- Damodar Valley = Gondwana coal belt = JH + WB
- DVC Thermal Plants: Bokaro, Chandrapura, Patratu (Jharkhand)
- Coal → Thermal Power → supplied to Bihar + WB region
- Raniganj coal belt (WB) also near Bihar-JH corridor
-
Tilaiya Ultra Mega Power Project — Jharkhand
- Barakar River — part of Damodar Valley
- Also: DVC dams generate hydroelectricity
- Shale gas deposits in Damodar Basin (JH + WB)
- Also in: Bengal Basin, Vindhya Basin
- Future energy potential for Jharkhand
⚡ BPSC MASTER RECALL — Bihar/JH Energy
- Bihar = Barauni Oil Refinery (public sector, first pipeline endpoint)
- Jharkhand = largest coal reserves in India
- Jharia = largest bituminous coal region (Jharkhand)
- Tilaiya = hydro project, Jharkhand
- DVC thermal plants: Bokaro, Patratu, Chandrapura (JH)

🚨 EXAM TRAP
- Barauni = Bihar (public sector refinery) — NOT Jharkhand
- First pipeline = Naharkatiya–Nunmati–Barauni (originates Assam, ends Bihar)
- Coal reserves #1 = Jharkhand | Production #1 = Chhattisgarh
- Tilaiya Dam in Jharkhand is a hydroelectric project on the Barakar River and is frequently tested.
