Power Plants of Tamil Nadu
Energy questions are type-and-place matching, and Tamil Nadu offers every type: nuclear, lignite thermal, hydro, one of the world's great wind belts and a giant solar park.
| Plant / belt | Type | District / fact |
|---|---|---|
| Kudankulam | Nuclear | Tirunelveli; India's largest nuclear power station (with Russia) |
| Kalpakkam (MAPS) | Nuclear | Chengalpattu; India's first indigenously built PHWR station |
| Neyveli | Lignite thermal | Cuddalore; lignite mining-cum-power complex |
| Tuticorin Thermal | Coal thermal | Thoothukudi |
| North Chennai Thermal | Coal thermal | Tiruvallur (Ennore belt) |
| Mettur | Hydro + thermal | Salem; hydro at the dam plus thermal station |
| Kundah / Pykara | Hydro | The Nilgiris; early hydel systems |
| Muppandal belt | Wind | Kanniyakumari; among India's largest wind concentrations |
| Kamuthi Solar Park | Solar | Ramanathapuram; among the world's largest single-location solar plants when commissioned |
The nuclear pair is the most-tested contrast: Kudankulam in Tirunelveli (India's largest, built with Russia) versus Kalpakkam in Chengalpattu (India's first indigenously built PHWR station).
