Power Systems Application Engineering III
About The Position
The Power Systems Applications Engineer reports to the Applications Engineering Manager and is responsible for the electrical design and technical validation of Battery Energy Storage System (BESS) plants and associated balance of system equipment. This role serves as the primary technical resource for power system studies, protection coordination, equipment sizing, and distribution system design during the proposal and pre-execution phases. This position bridges sales, system engineering, drafting, supply chain, and project management by translating customer requirements into engineered electrical solutions supported by detailed studies and compliant designs. The engineer will be responsible for performing and documenting electrical analyses using ETAP and similar tools to ensure safe, reliable, and code-compliant system configurations.
Requirements
- Strong understanding of LV and MV power systems, including protection, distribution, and equipment selection.
- Strong understanding of power electronics, battery systems, and utility scale battery energy storage systems operation, engineering, and design.
- Working knowledge of electrical calculations (fault current, ampacity, arc flash, etc.).
- Familiarity with industrial communications and EMS/SCADA interfaces.
- Understanding of relevant industry standards (UL 1741, UL 9540, IEEE 1547, NEC).
- Strong interpersonal and communication skills
- Ability to develop and review single‑line diagrams, schematics, and layouts.
- Ability to interface with customers and internal cross‑functional groups.
- Bachelor’s degree in Electrical Engineering or related field required.
- Minimum 8 years of experience in application engineering, power systems engineering, or BESS/renewables engineering.
Nice To Haves
- Experience with BESS systems, inverters, transformers, MV/LV switchgear, or utility‑scale power systems preferred.
Responsibilities
- Develop conceptual and detailed electrical designs for utility-scale BESS plants and associated MV/LV distribution systems.
- Perform load flow, short-circuit, and arc-flash studies using ETAP; interpret results and implement required design modifications.
- Size breakers, switchgear, transformers, cables, grounding systems, and auxiliary distribution equipment in accordance with NEC, IEEE, and utility requirements.
- Design and review single-line diagrams, three-line diagrams, control schematics, and panel layouts.
- Evaluate equipment interrupting ratings, withstand ratings, and thermal limits to ensure code compliance and system reliability.
- Develop specifications for MV and LV switchgear, protective relays, transformers, and distribution panels.
- Review vendor technical submittals and validate compliance with study assumptions and project specifications.
- Contribute to the development of standardized study templates, protection philosophies, and design guidelines.
- Support customer technical discussions related to BESS, fault current, protection schemes, grounding strategy, and system performance.
- Interface with controls and EMS teams to ensure proper integration of protection, SCADA, and substation automation systems.
- Provide technical input during project handover to execution and commissioning teams.
- Lead development of technical proposals supporting the sales process, including conceptual and detailed system designs.
- Review customer RFPs and translate requirements into system configurations, layouts, and performance expectations.
- Serve as a subject‑matter expert on company’s BESS platform and system architecture
