What Energy Safety Response Group does
Energy Safety Response Group (ESRG) is a privately-held safety services firm founded in 2019 and headquartered in Delaware, USA, that provides testing, permitting, deployment, and lifecycle safety services for stationary energy storage systems (BESS). The firm operates across four service areas: testing (UL 9540A and related UL certification, pre-certification, and R&D testing at a proprietary battery fire testing facility); permitting, project review, and project development support including risk assessment and AHJ engagement; public safety training and emergency response planning; and lifecycle/emergency response subject matter expertise, including a 24/7 cloud-based situational awareness platform for remote fire-service guidance. ESRG's competitive position rests on a small but deeply credentialed bench of senior personnel — co-founders Nick Warner (formerly DNV GL), Paul Rogers (retired FDNY Lieutenant, NFPA 855 committee member), and Tom Bensen (fire investigator) — augmented by former FDNY Deputy Assistant Chief Ed Ferrier, former NFPA Assistant Chief Engineer Casey Grant, and other former FDNY/NYC code officials, giving the firm active influence over UL and NFPA standards that govern BESS approvals.
The firm sells primarily through consultative, relationship-driven engagements to battery and energy storage manufacturers, project developers and owners, the fire service, code officials and AHJs, insurance companies, utilities, and transportation/hazmat buyers. Revenue is generated through project-based testing fees, professional services for permitting and deployment, training engagements, and recurring lifecycle/subscription contracts that bundle 24/7 SME availability with the cloud-based monitoring platform. Pricing is quote-based and not publicly disclosed; contracts range from ad-hoc engagements to multi-year lifecycle arrangements. Third-party validation work, such as independent destructive fire safety testing of Eos Energy Enterprises' Z3 zinc battery modules, serves as both a delivery artifact and a marketing proof point.
Headcount sits in the 11–50 range and the firm operates nationally across the U.S. while claiming the ability to deliver remote fire-service response globally through its cloud platform.ESRG holds ISO 14001 environmental management certification and no public funding, M&A, or ownership disclosures are present in the source data.

Energy Safety Response Group competitors and assessment
Company assessmentEmerging players
- TRC Companies: TRC is an engineering, environmental, and energy consulting firm with growing practices in grid-scale storage safety, permitting, and risk assessment. Compares to ESRG on the permitting and lifecycle advisory layer for utility and developer clients.
Broad incumbents
- Bureau Veritas: Bureau Veritas is a global testing, inspection, and certification company with energy and battery testing capabilities. Overlaps with ESRG on BESS conformity assessment and code compliance, though it operates across many adjacent industries at much greater scale.
- TÜV SÜD: TÜV SÜD is a global testing, inspection, and certification firm with active energy storage testing services across stationary, mobile, and EV batteries. Comparable to ESRG in the testing and certification layer, though at materially larger scale and broader portfolio.
- Ramboll: Ramboll is a global engineering, consulting, and environmental services firm with energy transition and fire safety practices. Comparable to ESRG on the consulting and code compliance side for energy infrastructure, particularly in European markets ESRG does not yet serve.
- Tetra Tech: Tetra Tech is a large engineering and consulting firm with energy storage, environmental compliance, and risk assessment practices. Overlaps with ESRG on permitting, environmental review, and infrastructure safety for energy projects, though BESS fire testing is a smaller portion of its portfolio.
- UL Solutions: UL Solutions is the standards body behind UL 9540A, UL 9540, and UL 1973 and operates extensive testing and certification laboratories. While broader in scope, UL is a natural competitor and partner in BESS certification workflows where ESRG provides pre-certification and advisory support.
Direct peers
- DNV: DNV operates one of the largest independent energy storage testing, certification, and advisory practices globally, including BMS validation testing — the same service Nick Warner led before co-founding ESRG. DNV is the most direct competitor for BESS safety testing and certification advisory.
- Jensen Hughes: Jensen Hughes is a leading fire protection engineering and consulting firm with energy storage system safety practices. Comparable to ESRG in fire protection engineering, code consulting, and BESS risk assessment for utilities, developers, and AHJs.
- Exponent: Exponent provides engineering and scientific consulting with deep practices in failure analysis, fire investigation, and battery safety. Overlap with ESRG is strongest in fire/lithium-battery forensic investigation and expert witness work, with comparable scientific rigor and project economics.
- CTEH: CTEH provides environmental, emergency response, and industrial hygiene consulting including hazardous materials response. Directly comparable to ESRG's emergency response, HAZMAT remediation, and incident support service lines for industrial and energy clients.
