• 10+ years of hands-on experience with GEV e-terra Energy Management Systems in electric
utility transmission-grid environments.
• 10+ years of hands-on experience hands-on experience with eTerra Source Database modeling,
Database migration and maintenance. Implementation and migration experience of e-terra source
for more then 5 utilities.
• Strong understanding of bbranch models, breaker-oriented models, substation topology,
electrical connectivity, network islands, and transformer, generator, and load modeling.
• Experience supporting EMS network-model changes in production environments.
• Strong understanding of SCADA measurements and their relationship with EMS network models.
• Experience troubleshooting EMS database, topology, telemetry, or network-model issues.
• Working knowledge of transmission-system operations and real-time control-center environments.
• Strong experience with Linux/Unix and Windows environments, working knowledge of relational
databases and SQL.
• Strong analytical and troubleshooting skills, with the ability to work directly with utility customers
and cross-functional technical teams.
Roles & Responsibilities
• We are seeking an experienced EMS Source Database Modeling Expert with strong hands-on
expertise in transmission network modeling, EMS database configuration, model validation, and
production support.
• The candidate will maintain and enhance the eTerra EMS Source Database and network model,
support model imports and updates, migrate database and model between different version of
e-terra source, resolve database and topology issues, build customer migration changes, and
ensure accurate representation of the transmission system for real-time EMS applications.
• This highly technical role requires direct experience with eTerra EMS/AEMS environments, utility
transmission systems, SCADA/EMS integration, and network model lifecycle management.
• Develop, configure, maintain, and validate transmission network models within the EMS Source
Database environment.
• Model substations, buses, transmission lines, transformers, breakers and disconnect switches,
generators, loads, shunts, capacitor and reactor banks, and measurement and telemetry points.
• Create and maintain electrical connectivity and topology relationships.
• Support model changes for new substations, transmission expansions, equipment replacements,
network reconfiguration, and generator additions or retirements.
• Perform Source Database updates and promote validated model changes across development,
test, and production EMS environments.
• Validate model consistency between Source Database, real-time database, SCADA, and EMS
applications.
• Troubleshoot network connectivity errors, incorrect device status, telemetry mapping issues,
topology processing errors, missing or incorrect measurements, model synchronization issues, and
database build or deployment failures.
• Lead the technical delivery of e-terra source projects assigned and mentor the junior members.
• Work closely with EMS Applications, SCADA, Power Systems, Database, and Infrastructure
teams
