Document Intelligence for
Power Plants
P&ID extraction, relay setting sheets, asset condition assessments, and as-built reconciliation for thermal and renewable power generation. 99.5% accuracy SLA.
Thermal plant P&ID digitization: boiler (steam generator), turbine, condenser, feedwater, fuel handling, ash handling, BOP systems
IBR Form IV register automation for power plant boilers, economisers, superheaters, reheaters, and IBR-scoped steam piping per ASME B31.1
Relay setting sheet extraction: structured protection databases for 110kV / 220kV / 400kV substations and generator protection schemes
Protection coordination studies: multi-manufacturer relay format consolidation (ABB, Siemens, GE Multilin, SEL, Alstom/GE) per IEC 61850 and IEEE standards
Asset condition assessment (ACA) reports: structured extraction for fleet management and mid-life refurbishment planning
Planned outage / turnaround documentation: scope documents, isolation drawings, work permits, piping MTO for replacement piping
As-built tag registers from decades of plant modifications: MoC consolidation across unit lifecycle
Gas turbine and combined-cycle (CCGT) plant documentation: HRSG (Heat Recovery Steam Generator) P&IDs, gas turbine instrumentation
Renewable energy documentation: solar PV single-line diagrams, wind turbine datasheets, battery storage BMS documentation, hybrid plant controls
Nuclear power plant documentation (where applicable): AERB-compliant register maintenance, IAEA safety case documentation, PHWR specifics for Indian nuclear operators
Transmission / distribution substation documentation: GIS equipment datasheets, switchgear P&IDs, CT / PT configurations, SCADA integration
NTPC / Tata Power / Adani Power / JSW Energy standards: documentation formatted per utility standards for audit and regulatory submission
Why do power plants need P&ID management software?
Indian thermal power fleet carries 60+ years of accumulated engineering documentation; NTPC alone has 26 coal-fired units at various vintages. Every plant has accumulated thousands of P&IDs across expansion phases, R&M (Renovation & Modernisation) projects, safety upgrades, and environmental retrofits (FGD / SCR / ESP upgrades). The as-built plant state is commonly documented only in paper archives or outdated CAD files. Regulatory demands are significant: IBR Form IV registers for every pressure-containing component, CEA safety inspections, pollution control board submissions, Chief Electrical Inspector audits. Document intelligence automates extraction from legacy documents into SAP PM and structured registers, enabling modern asset management, outage planning, regulatory compliance, and fleet-level predictive maintenance without re-drawing every P&ID. For utility operators with 10+ GW fleets, Pathnovo's managed service scales to the required workload.
How does document intelligence support power plant turnarounds and unit overhauls?
Thermal power turnarounds are capital-intensive with severe schedule sensitivity; unit on-bar value is $120,000-360,000 per day of lost generation. Turnaround planning requires accurate P&ID data, current asset condition records, valid IBR inspection status, current equipment datasheets for replacement items, and fresh procurement packages for replacement piping / valves / instruments. Pathnovo accelerates five workflows: (1) piping MTO from legacy isometrics for replacement scope, (2) IBR register refresh for post-outage Chief Inspector certification, (3) weld schedule / NDE plan per ASME B31.1 for new welded components, (4) relay setting re-coordination after protection scheme changes, (5) Day 1 post-outage SAP PM data refresh. Typical unit overhaul documentation-critical-path compresses 30-50%.
What power plant documents can Pathnovo process?
Full power-industry document spectrum: P&IDs for all plant systems (boiler, turbine, condenser, feedwater, fuel handling, ash handling, water treatment, BOP, electrical), relay setting sheets, protection coordination studies, asset condition assessments, turnaround work packs, IBR compliance documentation per ASME B31.1 / IBR 1950, gas turbine / HRSG documentation, CCGT plant drawings, renewable energy single-line diagrams, nuclear AERB documentation (where applicable), and SCADA / substation automation records per IEC 61850.
Can Pathnovo handle legacy power plant drawings?
Yes. Indian thermal fleet includes significant legacy documentation: 1960s-1980s hand-drawn P&IDs for early NTPC / state electricity board plants, 1990s-2000s early CAD exports, and modern intelligent P&IDs. Faded scans, hand-annotated revision markups, and non-standard conventions from successive plant expansions all handled. Brownfield digitization at scale (10,000+ P&IDs) with 99.5% contractual accuracy SLA; see the McDermott reference benchmark (10,247 tags across 600 P&IDs with zero QA rejections).
Does Pathnovo support relay setting and protection coordination?
Yes. Relay setting sheet extraction is a specialised capability: power protection engineers maintain multi-manufacturer relay format data (ABB REF 615 / RED 670, Siemens SIPROTEC, GE Multilin 469 / 345, SEL 351 / 787, Alstom/GE MiCOM P series, L&T LT series). Pathnovo normalises these formats into a structured protection database for coordination analysis, fault level verification, and IEC 61850 substation automation configuration. Protection zone validation per IEEE C37 series supported.
Do you support renewable energy and hybrid plant documentation?
Yes. Solar PV documentation (inverter datasheets, DC / AC single-line diagrams, string configurations, tracker controls), wind turbine documentation (nacelle equipment, pitch / yaw systems, SCADA integration), battery storage BMS and thermal management documentation, and hybrid plant controls (solar + battery + diesel / grid integration). Renewable asset developers scaling fleets across multiple sites benefit from Pathnovo's multi-site consolidation: consolidated asset register across 20-50+ renewable sites in one dashboard.
Which Indian power operators does Pathnovo serve?
Central utilities: NTPC (India's largest power producer, 73 GW capacity across thermal, hydro, solar, nuclear), NHPC (hydro), SJVN, THDC. State utilities: individual state electricity boards and power generation corporations. Private: Tata Power, Adani Power, Reliance Power, JSW Energy, Torrent Power, GMR Energy, Lanco (historical), CESC, Vedanta Power, Jindal Power. BHEL (Bharat Heavy Electricals) supplies IBR-certified boilers globally; Pathnovo supports BHEL's boiler supply documentation workflow. Renewable operators: ReNew Power, Greenko, Azure Power, Adani Green, Tata Power Renewables.
How does Pathnovo integrate with power plant SAP PM / Maximo?
Pre-certified SAP PM S/4HANA and IBM Maximo 7.6 / MAS 8.x connectors. Power plant asset hierarchies (unit → system → subsystem → equipment → instrument loop), PM schedules based on equipment type and regulatory requirements (IBR periodic inspection for boilers, CEA guidelines for safety inspection), condition monitoring points from instrument tags, and inspection registers all populated from extracted engineering data.
