Greenflash
Overview
Greenflash Infrastructure is a fast-growing independent power producer (IPP) backed by H.I.G. Private Equity. The company acquires, develops, finances, owns, and operates grid-scale energy storage, and data center Power Shell projects across the U.S. Powered by one of the strongest teams in the industry, Greenflash is currently executing over 2 GW of projects with an active 5 GW development pipeline.
Role Overview The Electrical Engineer will support the technical execution of large-scale energy infrastructure projects including Battery Energy Storage System (BESS) and Data Centers, with a focus on power system reliability, grid integration, and high-voltage engineering. This role requires expertise in power systems analysis, interconnection processes, and electrical equipment design. The engineer will play a critical role in ensuring seamless coordination across utilities, ISOs/RTOs, developers, EPC partners, and technology providers to deliver technically sound, SB-6-compliant, and reliable interconnection solutions.
This role will be located in Texas preferably in Houston, and reports to the Vice President of Engineering & Technology.
Primary Responsibilities
Perform power system modeling and studies (load flow, dynamic, and transient stability analyses) for large-scale electrical interconnections, including data centers and Battery Energy Storage Systems (BESS).
Support interconnection studies and regulatory filings, including RIOO-IS submissions, QSA deliverables, and LSIPA attestations (e.g., ERCOT, SPP, CAISO).
Evaluate and model large electronic loads, UPS systems, and ride-through behavior under voltage and frequency disturbances.
Conduct technical reviews of HV (e.g., 345kV, 138kV) substation and interconnection facility designs, ensuring compliance with ERCOT, NERC, and IEEE standards.
Support procurement evaluations for major electrical equipment such as transformers, switchgear, UPS, and circuit breakers.
Assist in the design and validation of islanding and microgrid configurations to enhance project resilience and operational reliability.
Collaborate with utilities, EPCs, EMS, OEMs, consultants, developers, and data center operators to resolve design and interconnection challenges.
Interpret and apply grid codes, ride-through standards, and interconnection requirements (IEEE 2800, NERC PRC, ERCOT).
Ensure project designs and interconnection studies align with ERCOT SB-6 reliability and dispatchability requirements, including verification of backup generation, system stability, and firm capacity performance.
Review and validate engineering documentation, protection schemes, and power quality analyses to ensure robust, high-availability operation.
Document lessons learned and contribute to continuous improvement of internal engineering and interconnection processes.
Education & Certifications
Bachelor’s degree in Electrical Engineering from an accredited institution (Master’s strongly preferred).
Professional Engineer (PE) license or eligibility preferred.
Professional Experience
At least 2 years of experience in power systems, transmission, interconnection, or large-scale electrical infrastructure (data centers, BESS, renewables, or T&D).
Proficiency with power system modeling tools such as PSS®E, PSLF, PSCAD, ETAP, or DIgSILENT PowerFactory.
Experience with high-voltage design, equipment specifications, and interconnection studies.
Familiarity with utility interconnection processes, grid compliance standards, and project permitting workflows in ERCOT.
Exposure to data center electrical systems (UPS, generators, switchgear), grid-forming power converters, and BESS applications.
Knowledge of grid-forming controls, black-start/islanding, and resilience strategies.
Understanding of harmonic analysis and power quality issues in electronic load environments.
Familiarity with protection and coordination studies for high-reliability operations.
Knowledge of ERCOT market rules, interconnection agreements, and compliance procedures.
Strong communication and coordination skills for multi-disciplinary collaboration, and manage external consultants and vendors.
Adaptable and solution-oriented, with a commitment to innovation, reliability, and continuous improvement.
