What BESS advisory does A3 provide?
End-to-end BESS advisory: feasibility, technology selection, interconnection, IRA incentive structuring including the 30% ITC plus domestic content and energy community adders, financing, and deployment. A3 works across containerized BESS, industrial microgrids, port-scale BESS, and first- and second-life battery supply chains.
Does A3 work on port electrification?
Yes. A3 has active port electrification work at the SC Ports Wando Welch Terminal, including reefer-yard diesel displacement and BESS and shore power infrastructure. Andrew Dunn is convening a port electrification panel with SC Ports in Summer 2026.
What regions and markets does A3 serve?
A3 starts local in the South Carolina Lowcountry and works across the U.S. Southeast, Mid-Atlantic, Texas, Midwest, and California. International engagements and partners span Canada and Mexico; the Caribbean and Central America, with active work in Puerto Rico and Jamaica; South America, with strategic focus in Brazil, Chile, and Ecuador; Europe and Africa; and extensive work across Southeast Asia, including the Philippines and Australia — among other emerging markets.
What industries and clients does A3 work with?
A3 advises utilities, OEMs, integrators, developers, startups, municipalities, ports, airports, and industrial and commercial facilities. Work spans utility grid modernization, DER ecosystems, C&I energy systems, microgrid architecture, data center and AI-related energy infrastructure, and maritime and port electrification.
What makes A3's approach different?
A3 works at the intersection of engineering, economics, policy, and operational execution simultaneously, prioritizing what actually deploys, scales, and survives financially over hype. Every engagement weighs interconnection realities, utility relationships, incentives, tariffs, grid constraints, customer economics, and long-term resilience.
What is A3's relationship with FENECON and Stokes Energy?
Andrew Dunn serves as Energy Solutions and Sales Director at FENECON USA, leading containerized BESS, FEMS/EMS integration, and industrial microgrid efforts across North America. Independently, he serves as a strategic advisor to a connected set of energy and infrastructure companies — including Stokes Energy, Molecule Systems, Mavericks Microgrids, and GreenPack (via Edge Energy), among others. A3 Consultancy operates as an independent platform that coordinates strategy across these aligned partners while remaining vendor-neutral.
Does A3 help with IRA incentives and project financing?
Yes. A3 structures projects around available federal incentives — including the investment tax credit (ITC) with domestic content, energy community, and brownfield adders, plus accelerated depreciation and other market and program incentives — and advises on financing strategy, commercialization pathways, and capital structures, from project-based and success-fee arrangements to co-development SPVs and blended finance for international work.
Does A3 provide expert witness, academic, or policy support?
Yes. Beyond development and advisory work, Andrew Dunn serves as a subject-matter expert for institutions, universities, and counsel — including expert witness testimony and technical reporting for energy and infrastructure disputes, academic research collaboration and co-authoring, guest lectures and keynotes, and policy and program design support. A3 is currently collaborating on data-center optimization grant initiatives, including a U.S. Department of Energy GENESIS grant and an Elemental Capital grant application, with research partners such as Clemson University.
