Role Description We are seeking an Instrumentation Engineer with deep experience in utility-scale solar to lead the specification, integration, commissioning, and lifecycle support of field instrumentation and industrial communication protocols, including Modbus RTU/ASCII, Modbus TCP, and DNP3. You will own the end-to-end telemetry chain—from met station sensors and data loggers to SCADA/EMS points—ensuring accurate, reliable, secure, and standards-compliant data exchange for real-time control, performance analytics, and regulatory reporting. You’ll collaborate closely with SCADA, controls, performance engineering, EPCs, and O&M partners to deliver highly available plant data systems that scale. What You’ll Do - Design & Specification - Define instrumentation architecture for met stations (irradiance, ambient temp, module temp, wind, barometric pressure), grid interconnection points, and balance-of-plant systems. - Author bill of materials (BOM), wiring diagrams, loop sheets, panel layouts, and instrument datasheets per project standards. - Select sensors, transducers, loggers, gateways, and protective devices aligned with IEC/IEEE/NEMA and utility requirements. - Protocol Integration - Configure and map points for Modbus RTU/TCP, DNP3 (secure/authenticated where applicable), and vendor-specific interfaces. - Develop point lists, registers, scaling, units, deadbands, and exception reporting to SCADA/EMS/Historian systems. - Implement time synchronization (NTP/IRIG-B), event logging, and sequence-of-events (SOE) requirements. - Commissioning & Validation - Plan and execute FAT/SAT for met stations and plant instrumentation; perform end-to-end signal checks (sensor → controller → gateway → SCADA). - Create and run test scripts for protocol polling, quality flags, and fallback logic; verify data accuracy against handheld calibrators and reference instruments. - Troubleshoot field issues (noise, grounding, shielding, RS-485 biasing/termination, baud rate/link-layer settings, device IDs, master/slave roles). - Reliability, Cybersecurity & Compliance - Apply best practices for failover, redundancy, and health monitoring (watchdogs, heartbeats, CRC validation). - Support secure configurations (role-based access, encrypted transport for TCP variants, DNP3 Secure Authentication, network segmentation/VLANs). - Ensure compliance with utility interconnection, RTO/ISO telemetry specifications, and relevant standards (e.g., IEEE, IEC, NERC CIP collaboration with IT/OT teams). - Operational Excellence - Build dashboards and alarming for sensor drift, data gaps, calibration due dates, and instrument health KPIs. - Author SOPs, calibration procedures, and maintenance schedules; train field techs and O&M teams. - Provide root-cause analysis for data anomalies impacting performance models and production guarantees. Qualifications - 5+ years hands-on experience in utility-scale solar (100 MW+ projects preferred), focusing on plant instrumentation and SCADA/OT integration. - Proven expertise with Modbus RTU/ASCII, Modbus TCP, and DNP3 (points mapping, scaling, polling strategies, exception reporting, time sync). - Strong knowledge of meteorological station instrumentation (pyranometers, reference cells, anemometers, temp probes, pressure sensors), data loggers, and gateways. - Proficiency with RS-485 physical layer (termination, biasing, shielding), industrial Ethernet, and serial-to-TCP conversions. - Ability to read and produce P&IDs, single-line diagrams, wiring/loop sheets, and panel layouts (AutoCAD or equivalent). - Experience commissioning instrumentation in the field, including calibration, verification, and troubleshooting. - Familiarity with SCADA/Historian systems (e.g., Ignition, Wonderware/AVEVA, PI, ClearSCADA) and OT networking fundamentals. - Excellent documentation, communication, and cross-functional collaboration skills. Preferred Qualifications - Experience with DNP3 Secure Authentication, TLS-enabled gateways, and OT security best practices; exposure to NERC CIP environments. - Background with IEC 61850, MQTT, or OPC-UA integrations. - Knowledge of power plant controls (PCS/PPC), inverter telemetry, capacitor/reactor banks, switchgear, and protection relays (SEL, GE, ABB). - Familiarity with performance analytics (PR calculations, data QA/QC, sensor uncertainty, shading & soiling analysis). - Hands-on experience with FAT/SAT processes and test plan development. - Experience working with EPCs, utilities, and ISOs/RTOs on telemetry and compliance packages. - Bachelor’s degree in electrical engineering, Instrumentation/Controls, or related discipline (advanced degree a plus). Tools & Technologies - Protocol analyzers (Modbus/DNP3), serial sniffers, and network analyzers. - Calibration tools for irradiance, temperature, and wind sensors; traceable standards. - AutoCAD or equivalent for drawings; EPLAN/ETAP exposure is a plus. - SCADA/Historian clients; scripting for test automation (Python, PowerShell, or similar). Key Outcomes (First 12 Months) - Commission multiple met stations with fully validated telemetry (quality flags, accurate scaling, synchronized timestamps). - Deliver complete point lists and interface control documents (ICDs) for Modbus/DNP3 across inverters, meters, reclosers, and met stations. - Establish instrumentation health monitoring and calibration program reducing data gaps by ≥ 50%. - Improve data quality feeding performance models and regulatory reporting, cutting QA/QC rework by ≥ 30%.
