Licensed Battery Storage Engineers in the United States.
BESS sizing, NFPA 855 and UL 9540 review, electrical single-lines, structural foundations, and interconnection — from licensed P.E.s across all 50 states.
The engineering layer behind every BESS deployment.
Battery storage projects fail when sizing, fire code, and interconnection aren't coordinated up front. A storage engineer brings electrical, structural, and code-review disciplines together — and signs the drawings that get the project permitted.
EngineerMint connects developers, EPCs, and asset owners with licensed battery storage engineers across the country, with credentials cross-checked against state licensing boards before engagement.
Post a brief — behind-the-meter peak shaving, solar-plus-storage retrofit, or utility-scale BESS — and receive proposals from licensed P.E.s.

Frequently asked questions
What does a battery storage engineer do?+
Battery storage engineers size and design BESS for peak shaving, demand charge management, backup power, frequency response, and solar-plus-storage — with NFPA 855 and UL 9540 fire-code review and interconnection support.
Do BESS projects need a licensed P.E.?+
Yes — interconnection applications, AHJ permit sets, electrical single-lines, and structural foundations for containerized BESS all require a Professional Engineer seal in the project state.
What standards apply to battery storage?+
NFPA 855 (fire code), UL 9540 and UL 9540A (system and unit certification), IEEE 1547 (interconnection), and IBC chapters for structural and electrical installation. Local AHJs increasingly require pre-installation thermal runaway review.
How is BESS sized?+
Sizing depends on use case — peak shaving uses interval data to set kW and kWh; backup uses critical load study; solar-plus-storage uses production modeling. A storage engineer combines these with degradation, augmentation, and warranty assumptions.
How much does battery storage engineering cost?+
Behind-the-meter BESS engineering runs $5K–$50K depending on size and AHJ complexity; utility-scale runs into six and seven figures. Use the AI Estimator for a project-specific range.
