Interconnection Engineer information

What is an interconnection engineer?

Interconnection Engineers are professionals who design, manage, and oversee the processes required to connect energy generation systems—such as solar, wind, or traditional power plants—to the electric grid. They work closely with utilities, developers, and regulatory agencies to ensure that new energy projects meet technical standards and regulatory requirements for safe and reliable grid integration. Their responsibilities include conducting technical studies, reviewing interconnection applications, and coordinating with various stakeholders to resolve engineering challenges. This role is critical in supporting the expansion of renewable energy and maintaining grid stability.

What are some common challenges an interconnection engineer faces when coordinating with utilities and project stakeholders?

Interconnection Engineers often encounter challenges such as navigating complex utility requirements, managing tight project timelines, and ensuring all technical documentation meets regulatory standards. Communication with utility representatives and project teams can be intricate, as requirements may vary by region and change frequently. Being proactive in documentation, maintaining clear communication, and staying updated on evolving interconnection standards are crucial for success in this collaborative and fast-paced role.

What are the key skills and qualifications needed to thrive as an interconnection engineer, and why are they important?

To thrive as an Interconnection Engineer, you need a solid background in electrical engineering, power systems, and grid interconnection standards, often supported by a bachelor's degree in engineering. Familiarity with power system modeling tools (such as PSS®E, PSCAD, or PowerWorld), relevant regulations (like FERC, NERC), and industry certifications (such as PE licensure) is typically required. Strong analytical thinking, project management abilities, and clear communication skills help you collaborate effectively with utilities, developers, and regulatory bodies. These skills are essential to ensure safe, efficient, and compliant integration of new energy projects into the electric grid.

What is the difference between Interconnection Engineer vs Power Systems Engineer?

AspectInterconnection EngineerPower Systems Engineer
Required CredentialsBachelor's in Electrical Engineering, certifications like PE or EIT often preferredBachelor's or Master's in Electrical Engineering, PE license common
Work EnvironmentUtility companies, renewable energy firms, grid operatorsPower generation, transmission, and distribution companies
Industry UsageFocuses on connecting new energy sources to the gridDesigning and analyzing power systems for efficiency and reliability

Interconnection Engineers primarily focus on integrating new energy projects into the grid, ensuring compliance and connection approval. Power Systems Engineers work on designing, analyzing, and optimizing entire power systems. While both roles require electrical engineering expertise and often similar certifications, their focus areas differ—interconnection engineers concentrate on grid connection processes, whereas power systems engineers focus on system performance and design.

Job description

The Interconnection Engineer is responsible for managing solar, storage and hybrid projects through the RTO/utility interconnection process through all stages of the project life cycle. This role requires an engineer with experience managing Generation Interconnection projects through multiple utility and RTO interconnection processes. This is a multi-faceted role that offers a lot of growth opportunity to offer strategic direction to a rapidly growing team and renewable pipeline for Sol Systems. The candidate will report to the VP, Transmission Strategy and be an integral member of Development team.
Sol Systems is an Independent Power Producer (IPP) committed to building, owning, and managing clean energy infrastructure that benefits local communities. With GWs of projects across 30 states, Sol integrates energy storage and grid resiliency solutions to deliver reliable, sustainable power to Fortune 500 companies, municipalities, utilities, and schools. Through strategic partnerships and community reinvestment, Sol ensures clean energy development drives long-term economic and environmental benefits. Founded in 2008 and led by its founder, Sol Systems is dedicated to shaping an energy future we can all believe in.
Key Responsibilities
  • Partner closely with the Development Operations, Enterprise, Engineering, Pre-Construction, Construction, and Asset Management teams to successfully deliver utility-scale generation projects through the interconnection process.
  • Manage Sol's interconnection queue positions, including preparing and maintaining interconnection applications, modeling packages, and supporting documentation while coordinating with utilities and RTOs to satisfy interconnection requirements.
  • Manage external consultants responsible for electrical modeling, interconnection studies, curtailment assessments, and congestion analyses to ensure high-quality, timely deliverables.
  • Serve as the project manager for interconnection activities, driving projects through the interconnection process while supporting greenfield efforts.
  • Support mergers and acquisitions (M&A) activities by evaluating interconnection reports, System Impact Studies, Facilities Studies, and Generator Interconnection Agreements (GIAs) to identify technical risks, schedule impacts, and potential fatal flaws.
  • Develop, or oversee the development of, interconnection request packages, including single-line diagrams, electrical models, and supporting technical documentation for utility-scale solar PV, battery energy storage systems (BESS), and hybrid generation projects.
  • Review utility and RTO interconnection study results, network upgrade requirements, and cost estimates to identify opportunities to reduce project cost, schedule, and execution risk.
  • Lead Generator Interconnection Agreement (GIA) negotiations with utilities and RTOs through execution.
  • Represent Sol in utility and RTO stakeholder meetings, technical working groups, and industry committees, while monitoring regulatory, tariff, and market rule changes that may affect project development and interconnection strategy.
  • Perform market intelligence analysis.

Qualifications
  • Bachelor's degree in Electrical Engineering; concentration in Power Systems strongly preferred.
  • 0-5 years of relevant professional experience following graduation.
  • Professional Engineer (PE) license preferred.
  • Strong understanding of power system fundamentals and analysis.
  • Experience working with one or more North American wholesale electricity markets or RTOs, including PJM, MISO, ERCOT, or SPP, is strongly preferred.
  • Working knowledge of transmission planning studies and industry-standard power system modeling tools such as PSSE and TARA is strongly preferred.
  • Excellent written, verbal, and interpersonal communication skills, with the ability to effectively collaborate across technical and cross-functional teams.

Location: This is a full-time hybrid role based in Sol's Washington, DC headquarters. Remote option is not offered this time.
Commitment & Compensation: The base salary for this role is between $95,000 and $130,000 annually, depending on the candidate's experience, qualifications, and overall fit for the position. In addition, Sol Systems provides health insurance, retirement benefits, partial gym reimbursement, transportation benefits, education benefits, paid vacation and federal holidays, plus the opportunity to work in an entrepreneurial environment.
