Indian 660 MW Supercritical Coal Power Plant MEP — CEA + CPCB 2022 + IBR + ASME PG + USEPA NSPS

A 660 MW supercritical Indian coal plant demands ₹12,445 Cr MEP capex with coal handling + pulveriser + supercritical boiler (570°C/250 bar) + ESP + bag-house + wet-FGD + SCR + 175 m cooling tower + ash handling + Hg sorbent. CEA + CPCB 2022 + IBR + ASME PG + USEPA NSPS + IEA govern. India fleet 220 GW; FGD compliance 55 % (2024) vs 2022 deadline. Three failures: FGD retrofit delays facing ₹0.05/kWh penalty + closure, SCR catalyst poisoning by high-ash + arsenic in 12-18 mo, fly ash utilisation < 100 % stockpiling 30-40 %.

Indian 660 MW supercritical coal power plant framework

India coal power (NTPC + Tata Power + Adani Power + Reliance Power + JSW Energy + state utilities — Maharashtra Mahagenco, Karnataka KPCL, Tamil Nadu TANGEDCO, Gujarat GSECL) operates 220 GW coal capacity. New build is 660-800 MW supercritical + ultra-supercritical. Standards stack — CEA Coal Power Plant Standards + MoEFCC Coal Plant Emission Norms 2015 (revised 2022) + worldcoal + IEA Coal Roadmap + IBR Indian Boiler Regulations + ASME PG (Power Generation) + IS 1448 (coal) + USEPA NSPS Subpart D + EU IED.

660 MW supercritical coal plant MEP scope

Three Indian 660 MW coal plant MEP failures

1. FGD retrofit delayed for cost — penalty growing — CPCB 2022 deadline missed at 68 % Indian fleet. Wet-FGD capex ₹920 Cr per 660 MW unit + 1.5-2 % efficiency penalty. State PSU + private operators delaying — face ₹0.05/kWh penalty + closure threat.
2. SCR catalyst poisoning by ash + arsenic — Indian coal high-ash (35-45 %) + arsenic 5-15 ppm poisons SCR catalyst in 12-18 months vs design 4-yr life. Specify catalyst with arsenic resistance + frequent regeneration.
3. Coal ash 100 % utilisation mandate failing — CPCB mandates fly ash 100 % utilisation (cement + brick + reclamation). Indian thermal plants stockpile 30-40 % unused. Specify dedicated dry-bottom ash + utilisation contract at commissioning.
