Indian Captive Coal Power Plant (CPP) MEP — CEA Captive 2024 + CPCB Captive 2022 + IBR + ASME PG

A 250 MW Indian captive coal power plant demands ₹4,840 Cr MEP capex with subcritical boiler (135 bar / 540°C) + steam turbine + ESP + bag-house + FGD + cooling tower + ash handling + cogeneration option. CEA Captive 2024 + CPCB Captive 2022 + IBR + ASME PG + Electricity Act 2003 govern. Indian captive 70+ GW; steel 78 % + aluminium 85 % captive. Three failures: sub-critical at small size losing 6-8 % efficiency (cogenerate to recover), FGD retrofit delayed facing penalty, dual-mode grid interconnect missed for surplus sale per CEA Captive 2024.

Indian captive coal power plant (CPP) framework

Indian captive power (CPP) — Tata Steel + JSW + Vedanta + Hindalco + Reliance + Adani + ACC + Ambuja + UltraTech + Reliance — total 70+ GW captive capacity. Used for power-intensive industry. Standards stack — CEA Captive Generation Rules 2024 + CPCB Captive Power Plant Norms 2022 + MoP Tariff Order + Electricity Act 2003 + IBR + ASME PG. Mostly 100-300 MW units; some 660 MW supercritical.

250 MW captive coal power plant MEP scope

Three Indian captive coal plant MEP failures

1. Sub-critical 135 bar at small unit size — sub-critical efficiency 36-38 % vs supercritical 40-44 %. CPP < 250 MW captive cant justify supercritical capex but loses 6-8 % efficiency. Solution: cogeneration with process steam to host industry — boosts overall energy efficiency to 60-70 %.
2. FGD not retrofit on legacy CPP — CPCB Captive Power 2022 mandates SO2 50 MW. Many state-private CPPs delay retrofit — face penalty + closure. Capex ₹385 Cr per 250 MW unit.
3. Grid interconnection for surplus sale missed — CPP with surplus often locked in 100 % captive mode. Open-access framework allows grid sale at higher tariff. Specify dual-mode CPP per CEA Captive Rules 2024.
