Grid Integration Engineer II

Power Systems Engineer – Grid Integration Engineering

Invenergy is North America's largest privately held developer, owner, and operator of power infrastructure. With 25 years of trusted execution, we deliver reliable, affordable energy through a diverse portfolio that includes natural gas, solar, land-based wind, energy storage, transmission, and domestic manufacturing. Headquartered in Chicago, we develop, own, and operate large scale projects that power communities and support the energy future.

The Power Systems Engineer – Grid Integration Engineering will support Invenergy's grid integration, advanced modeling, and interconnection engineering activities across generation, transmission, and large-load development projects. Based in Invenergy's Chicago office, this role will perform power system analysis and technical evaluations to support project development, grid-code compliance, and system performance validation across multiple ISO/RTO markets.

The Power Systems Engineer will contribute to engineering activities associated with inverter-based resource integration, large-load interconnections, and advanced power system modeling. The role will support internal teams by reviewing ISO/RTO interconnection studies, assisting with modeling activities, and coordinating engineering efforts required to meet evolving grid performance standards.

This position will work closely with internal teams including Interconnections, Grid Modeling, Development, and Engineering to ensure projects meet grid integration requirements and maintain alignment with evolving regulatory and reliability standards.

Responsibilities

• Perform technical analysis to support grid integration and interconnection activities for generation and large-load projects.
• Review ISO/RTO interconnection electromagnetic transient studies and provide technical evaluation of study results.
• Assist with interconnection and engineering activities for the Grain Belt Express (GBX) HVDC project, including technical discussions with RTOs/ISOs, coordination with OEMs, engineering contractors, and internal project teams.
• Assist with advanced power system modeling activities including power flow, stability, and electromagnetic transient (EMT) analysis.
• Support evaluation of grid-code compliance requirements, including system performance during disturbances and inverter-based resource integration.
• Assist in engineering evaluations for data center and large-load interconnection projects, including analysis of dynamic load behavior and grid stability impacts.
• Coordinate with internal modeling teams and external consultants to develop system models and perform reliability and performance studies.
• Assist in the preparation and validation of power system models used in ISO/RTO interconnection processes.
• Support development of conceptual designs for interconnection facilities, substations, and transmission upgrades associated with new generation and load projects.
• Assist in interpreting ISO/RTO market rules and interconnection requirements applicable to project development and operation.
• Provide technical support to Development, Origination, Engineering, and Commercial teams in evaluating grid integration opportunities and constraints.
• Participate in ISO/RTO stakeholder meetings and technical working groups related to interconnection and grid performance requirements.
• Support technical diligence efforts related to project acquisitions and M&A opportunities.
• Establish and maintain technical relationships with utilities, consultants, and ISO/RTO stakeholders
