Engineering Technologist

Company introduction Duke Energy operates a Distributed Energy Resource Management System (DERMS) for Behind-the-Meter and customer-sited assets, supporting the safe, reliable, and efficient operation of distributed energy resources across the distribution network. Role summary / purpose The DERMS Engineering Technologist supports the safe, reliable, and efficient operation of the Distributed Energy Resource Management System (DERMS) for Behind-the-Meter and customer-sited assets. This role serves as an operator with responsibility for monitoring distributed energy resources (DERs), evaluating alarms and grid conditions, preparing dispatch actions, and executing approved actions under the direction of authorized distribution operations personnel. The role also maintains DERMS operational readiness, operational procedures, data quality, system interfaces, and accurate records. Key responsibilities DERMS Operations and Monitoring • Monitor DERMS dashboards, alarms, communications status, DER availability, telemetry quality, operating envelopes, and distribution-system constraints. • Assess thermal, voltage, power-quality, and equipment-limit indications and escalate abnormal conditions in accordance with approved operating procedures. • Prepare DER dispatch, curtailment, charge, discharge, or program actions for review and approval by authorized distribution operations personnel. • Execute approved commands, confirm receipt and response, compare expected and actual performance, and document outcomes in the operating record. • Support demand-response events, scheduled DER tests, and restoration to normal operating status while maintaining situational awareness. • Participate in the on-call rotation and respond to after-hours DERMS incidents, failed interfaces, data-quality issues, or unsuccessful control actions. Battery OEM Testing and Onboarding • Coordinate test schedules, prerequisites, test data, access, and readiness reviews with battery OEMs and internal stakeholders. Testing is expected to be performed remotely or from an assigned facility. • Execute approved laboratory, integration, interoperability, and operational acceptance test procedures for battery energy storage systems and associated gateways or aggregators. • Validate device registration, identity, certificate use, connectivity, telemetry, time synchronization, alarms, availability, nameplate and capability data, and command acknowledgement. • Test charge and discharge controls, active and reactive power functions, operating-envelope compliance, ramp rates, limits, default behavior, loss-of-communications response, recovery, and fail-safe operation, as applicable. • Capture reproducible evidence from DERMS, OEM, gateway, and interface logs. Record defects, expected results, actual results, severity, ownership, and retest status. • Troubleshoot failed tests with OEM and internal technical teams. Distinguish between device, communications, configuration, data-model, certificate, and DERMS issues and coordinate corrective actions. • Prepare an onboarding recommendation and supporting evidence package for review. System Maintenance, Data, and Integration • Perform approved routine DERMS administration, configuration checks, health checks, release validation, and post-maintenance verification. • Monitor and reconcile DER inventory, grouping, program enrollment, grid-model associations, device capabilities, and customer or service-point mappings. • Ident…
