DCS & HMI System Retrofitting Services for Thermal Power Plants
The Opportunity
India's aging thermal power stations require replacement of outdated SG-TG control systems with modern DCS (Distributed Control System) and HMI (Human-Machine Interface) solutions. Government power utilities regularly issue tenders for design, engineering, supply, retrofitting, and commissioning of these critical systems, but qualified specialized service providers are limited.
Market Size
₹8,000–12,000 crore annually. India operates ~160 thermal power plants; each unit replacement cycle is 15–20 years. NTPC, STPS, and state utilities collectively spend ₹500+ crore yearly on control system upgrades (source: Government e-procurement portals and power sector reports).
Business Model
B2B service firm specializing in DCS/HMI retrofitting for thermal power stations. Partner with global control system vendors (ABB, Siemens, Honeywell), bid on government e-tenders, and provide end-to-end design, engineering, supply, installation, testing, and commissioning services.
1. System supply markup (25–35% margin on ₹2–5 crore control system per unit); 2. Engineering & design consulting (₹50–150 lakh per project); 3. Installation, testing & commissioning labor (₹1–3 crore per unit over 6–12 months)
Your 30-Day Action Plan
Research RVUNL, PSPCL, and NTPC tender pipelines on eproc.rajasthan.gov.in and www.ntpctender.com; identify next 5–10 upcoming DCS retrofit tenders.
Contact 3–5 global DCS vendors (Siemens, ABB, Honeywell) for partnership/reseller agreements and pricing; secure technical documentation and certifications.
Hire 2–3 senior automation engineers with thermal power plant experience; develop proposal templates and cost estimation models.
Register as vendor on government e-procurement portals (eproc.rajasthan.gov.in, sppp.rajasthan.gov.in); submit pre-qualification documents for first tender bid.
Compliance & Regulatory Angle
GST: 5% on engineering services, 12% on equipment supply. ISO 9001, IEC 61508 (functional safety), and vendor certifications from power utilities required. Bid bonds (2–5% of tender value) and performance guarantees (10–20%) mandatory. Import duties apply if sourcing foreign components (5–15% depending on HS codes).
