Speaker biography
Daniel Hoy is a Senior Electrical Engineer and Battery Energy Storage Systems (BESS) Technical Lead with deep experience supporting large‑scale battery and hybrid energy projects across utility, mining, islanded, and remote power systems. He is regularly engaged as Owner’s Engineer, helping clients navigate technical risk, constructability, and long‑term operational performance across the full project lifecycle.
Daniel brings a strong delivery background, having started his career in Western Australia working on BESS projects under EPC and IPP models where he led detailed design, safety‑in‑design processes, commissioning support, and asset handover for operational facilities. This hands‑on contractor‑side experience enables him to provide practical, delivery‑focused advice and to confidently challenge OEMs and EPC contractors on behalf of asset owners.
In his current role as Team Lead for Hybrid Systems and Storage at GHD, Daniel acts as technical authority on high‑value BESS and hybrid projects globally. Daniel has supported projects for a wide range of clients including Shell Energy, BHP, Rio Tinto, Synergy, Western Power, Horizon Power, and government and development agencies in the UAE, the Philippines, Nauru and CNMI.

BESS duration requirements: What could the future hold for BESS Developers in WA?
Presentation summary
The Western Australian Reserve Capacity Mechanism has increased the Electric Storage Resource (ESR) duration requirement from 4 hours to 6 hours for the 2027–28 capacity cycle. This change reflects high penetration of BESS during peak demand periods. As a result, new utility‑scale BESS projects seeking capacity credits must now demonstrate 6‑hour dispatch capability, representing a material departure from the 4‑hour standard that underpinned most historical battery investments. This change has direct implications for project design, capital cost, and revenue modelling. Longer duration requirements increase upfront investment and affect energy‑to‑power sizing decisions. The framework also allows the ESR duration requirement to continue evolving with demand patterns, potentially leading to longer duration requirements in future cycles. When combined with declining equipment costs and increasing battery energy densities, this creates new considerations for future BESS development. This presentation examines how evolving revenue structures, energy costs, and technology trends may influence BESS design choices and development strategies going forward.
