Document Intelligence for
Power Plants

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.

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).

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.

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.

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.

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. See the engineering handover workflow for the full pipeline.

For utility operators (thermal and gas power generation, nuclear, hydro, transmission and distribution, gas distribution, water utilities), the best automated safety documentation solution covers eight document categories that historically sit in separate registers and systems: HAZOP and process safety, IBR safety case for boiler-scope equipment, AERB safety case for nuclear scope, fire and gas detection plus hazardous area classification plus electrical safety, SIL determination and safety instrumented function registers, work permit-to-work and isolation documentation, Management of Change safety records, and cross-utility safety case documents per regulator (CEA, PNGRB, OISD, AERB, CWC). Pathnovo automates the extraction layer across all eight categories from existing PDF safety studies, mill certificates, P&IDs, relay setting sheets, datasheets, and incident reports. The 99.5% contractual accuracy SLA on safety-critical fields (tag numbers, line numbers, design pressures, SIL classifications, hazardous-area zone classifications) is what distinguishes an EPC-grade safety documentation solution from generic document AI. See the HAZOP safety intelligence pillar for the safety register workflow and the IBR compliance page for the IBR-specific register.

Generic EHS management systems (Intelex, Sphera, Cority, Enablon) track safety actions, incidents, audit findings, and corrective actions over time. They do not read engineering documents. Automated safety documentation solutions (Pathnovo) read the source engineering documents from which the safety registers should be populated: HAZOP study PDFs, P&IDs, datasheets, mill certificates, isometric drawings, relay setting sheets, hazardous area classification drawings. The extraction layer feeds the EHS management system continuously rather than requiring manual data entry from each new document. For utility operators with hundreds of safety registers to maintain across multi-asset estates (NTPC 73 GW across 26 coal-fired units, Tata Power multi-site portfolio, Adani Power thermal + renewable hybrid), the manual data-entry burden between engineering documents and EHS system is the bottleneck. Pathnovo eliminates the bottleneck. Most utility operators end up with both: Pathnovo for the engineering-document-to-register extraction layer, plus an EHS management system downstream for action tracking and closure workflow.

Yes. Although the page focus is on power generation (the largest single utility sub-sector), the same extraction workflow applies across the full utilities sector. Transmission and distribution utilities use it for substation safety registers, earthing system documentation per IEEE 80, line patrol records, and lightning protection per IS 2309 / IEC 62305. Gas distribution utilities (GAIL, Mahanagar Gas, Indraprastha Gas) use it for PNGRB safety case documentation, pipeline integrity management per OISD 226, leak detection registers, and SCADA-linked safety records. Water utilities use it for treatment plant safety case, chemical handling registers, dam safety documentation per CWC (Central Water Commission) norms. Hydro utilities (NHPC, SJVN, THDC) use it for dam-and-powerhouse safety case across CWC, CEA, and AERB jurisdictions (where applicable). The common pattern: a utility operator with multi-decade asset history has accumulated safety documentation across regulators, sub-sectors, and document conventions, and Pathnovo's extraction layer consolidates the lot into a unified queryable register.
