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

FuelCell Energy is a global leader in decarbonizing power and producing hydrogen through our proprietary fuel cell technology. Our mission is to enable a world powered by clean energy. As an innovator and manufacturer of fuel cell clean power platforms, FuelCell Energy has the only technology in the world capable of capturing carbon from an external source and producing power at the same time. In addition, we offer the only technology in the world capable of producing hydrogen, power and water simultaneously.

The pay for this position ranges from $130000 - $160000.

Work location: Remote (U.S); On-site in Danbury, CT preferred. 

Overview

We are seeking a hands-on Lead Electrical Engineer to own the electrical design, integration, and commissioning of complex power systems for industrial energy projects. This role will be responsible for HV/MV/LV power architecture, utility interconnection, protection and coordination, grounding, control cabinet design, and field commissioning support.

The ideal candidate brings strong experience in power distribution, grid-connected systems, utility coordination, NEC/FC1/UL/CE compliance, arc-flash analysis, and practical execution from concept through commissioning. Experience with hydrogen, electrolysis, fuel cells, data centers, temporary microgrids, modular substations, or industrial power systems is highly desirable.

Key Responsibilities

         Lead electrical architecture for industrial power systems, including HV/MV/LV distribution, transformers, switchgear, auxiliary power, UPS systems, and grounding.

         Own utility interconnection requirements, including interface with utilities, EPCs, vendors, and internal engineering teams.

         Develop and review single-line diagrams, three-line diagrams, grounding plans, panel layouts, electrical room layouts, BOMs, cable schedules, and electrical design packages.

         Perform or lead protection and coordination studies, relay settings, arc-flash analysis, and arc-energy-reduction strategies.

         Ensure designs comply with applicable NEC, IEEE, NESC, UL 508A, NFPA, and site-specific electrical standards.

         Support DC power system design, including rectifiers, DC distribution, insulation monitoring, grounding/earthing strategy, fault limitation, and overvoltage protection.

         Lead UL 508A control cabinet design, review, and manufacturing support.

         Translate high-level system requirements into buildable electrical packages suitable for procurement, fabrication, installation, and commissioning.

         Support RFQs, bid leveling, vendor selection, technical reviews, FAT, SAT, energization, LOTO planning, and startup procedures.

         Coordinate with mechanical, controls, process, software, and field service teams to ensure integrated system performance.

         Provide field support during installation, commissioning, troubleshooting, and customer acceptance.

         Develop internal electrical standards, design guides, templates, and best practices to improve repeatability and reduce design cycle time.

         Mentor junior engineers and support technical development across the electrical engineering team.

Required Qualifications

         Bachelor's degree in Electrical Engineering or related field.

         10+ years of electrical engineering experience in industrial power systems, utility interconnection, power distribution, controls, or commissioning.

         Strong working knowledge of NEC, IEEE standards, UL 508A, grounding, bonding, electrical clearances, and electrical safety practices.

         Experience with MV/LV power distribution, transformers, switchgear, relays, protection coordination, and arc-flash studies.

         Experience developing electrical design packages, including SLDs, layouts, schematics, BOMs, and commissioning documentation.

         Ability to interface effectively with utilities, EPCs, vendors, customers, and internal engineering teams.

         Hands-on commissioning, troubleshooting, or field execution experience.

         Strong communication skills and ability to drive technical alignment across cross-functional teams.

Preferred Qualifications

         Engineer-in-Training, PE, or ability/desire to pursue PE licensure.

         Experience with hydrogen, electrolyzers, fuel cells, renewable energy, data centers, microgrids, or modular power systems.

         Experience with DC power systems, including rectifiers, 1,000 VDC+ distribution, insulation monitoring, and DC fault protection.

         Familiarity with ETAP, AutoCAD Electrical, EPLAN, SolidWorks Electrical, ElectricalOM, or similar tools.

         Experience with utility-scale or industrial power systems up to MV/HV levels.

         Experience with generator plants, BESS, black-start systems, load shedding, or temporary power applications.
