Group Applications Manager, Clarke Energy, a Rehlko companyJustin Lenoff is Group Applications Manager at Clarke Energy, a Rehlko company, with 15+ years leading hybrid energy system development across microgrids, distributed generation, and battery energy storage. He brings deep expertise in the integration of Distributed Energy Resources (DERs) — including energy storage systems, CHP, solar, and advanced microgrid controls — and has become a recognized industry voice on the application of hybrid gas-BESS architectures for AI data center power infrastructure.
At Clarke Energy, Justin leads the company's global microgrid strategy, overseeing hybrid system design, vendor selection, and inverter-centric control architectures across markets in the USA, UK, Australia, and Sub-Saharan Africa. He is responsible for developing feasibility studies, structuring long-term service agreements (LTSAs), and directing pre-sales modeling for a pipeline exceeding $500M in global microgrid opportunities. His most recognized project achievement is securing a $52M DOE grant for a long-duration solar-storage microgrid in Casa Grande, AZ. To date, he has developed over 250 MW of hybrid energy projects globally.
Justin's current focus is on volatile AI workload power challenges, including inverter-led dispatch strategies, ESS sizing methodologies, and CAPEX/OPEX trade-offs between lithium-ion and graphene storage technologies. He developed Clarke Energy's hybrid architecture standard for AI data center applications and has expanded the company's market footprint as a recognized first-mover in gas-plus-storage design. He is a sought-after speaker and published author on the topic — delivering sessions at AEE World 2025, AEE West 2026, EUEC 2025, IEEE, and author multiple whitepapers on hybrid solutions for AI load volatility.
