Senior Battery Energy Storage Systems Engineer - Remote

Senior Electrical Design Engineer – Battery Energy Storage Systems (BESS)

b19 is partnering with an established renewable energy company to find an experienced Senior Electrical Design Engineer to support the design and delivery of utility-scale Battery Energy Storage System (BESS) projects. This role is focused on the detailed engineering and design of AC collector systems, medium-voltage electrical infrastructure, and associated balance-of-plant (BOP) systems from concept through construction.

The ideal candidate has a strong background in electrical utility design, including collector systems, conductor sizing, equipment selection, and California GO95 requirements. Experience designing utility-scale battery storage facilities is essential.

Responsibilities

Electrical Design

• Lead the electrical design of utility-scale Battery Energy Storage System (BESS) collector systems.
• Develop engineering packages from conceptual design through Issued for Construction (IFC).
• Design medium-voltage AC collector systems, including overhead and underground distribution.
• Produce and review:
• Single-line diagrams
• Collector system layouts
• Electrical site plans
• Conduit and cable routing drawings
• Equipment layouts
• Bill of Materials (BOMs)
• Size medium-voltage and low-voltage conductors, cables, conduit systems, and raceways.
• Perform voltage drop, ampacity, fault current, and equipment loading calculations.
• Develop grounding and bonding designs for BESS facilities.
• Select and specify electrical equipment including:
• Pad-mounted transformers
• Medium-voltage switchgear
• Reclosers
• Sectionalizing switches
• Metering equipment
• Protective devices
• Underground structures and duct banks

Utility & Collector System Design

• Design overhead collector systems in accordance with GO95 requirements and applicable utility standards.
• Develop pole loading calculations and construction packages where applicable.
• Coordinate utility interconnection requirements for collector system interfaces.
• Prepare construction drawings for overhead and underground distribution systems.
• Ensure compliance with utility engineering standards and applicable electrical codes.

Project Delivery

• Support projects from early development through detailed engineering and construction.
• Coordinate with civil, structural, and mechanical disciplines to integrate electrical designs.
• Review vendor drawings and equipment submittals for compliance with project requirements.
• Prepare technical specifications and support procurement activities.
• Respond to Requests for Information (RFIs) and provide engineering support during construction.
• Participate in factory acceptance testing (FAT), site inspections, and commissioning activities as required.

Client & Team Collaboration

• Serve as a technical lead during client meetings and design reviews.
• Develop engineering scopes, schedules, and cost estimates.
• Mentor junior engineers and designers.
• Support continuous improvement of engineering standards, templates, and design procedures.

Qualifications

• Bachelor's degree in Electrical Engineering from an accredited university.
• 7+ years of electrical design experience in utility, renewable energy, or Battery Energy Storage System (BESS) projects.
• Strong experience designing medium-voltage collector systems.
• Demonstrated knowledge of California GO95 standards.
• Experience sizing conductors, cables, conduit, raceways, and electrical equipment.
• Experience preparing construction drawing packages using AutoCAD.
• Working knowledge of:
• NEC
• NESC
• GO95
• IEEE standards
• Utility engineering standards
• Strong understanding of electrical balance-of-plant (eBOP) design.
• Professional Engineer (PE) license or ability to obtain.
• Experience with utility-scale Battery Energy Storage System (BESS) or renewable energy projects.
• Experience designing collector systems for solar or battery storage facilities.
• Familiarity with utility interconnection requirements and construction practices.
• Experience using ETAP, EasyPower, CYMCAP, or similar engineering software.
• Knowledge of grounding design, cable ampacity studies, and equipment specification development.
• Experience coordinating multidisciplinary engineering projects.
• Strong written and verbal communication skills.
