Ms. O’Mullane is a specialist in distributed energy resources (DER), microgrid system design and commercial energy strategy, with extensive experience delivering complex decarbonisation and grid-edge programs across Australia, the Middle East and Europe. She is the former Senior Manager for DER at ENOWA (NEOM), where she established and led the utility’s DER business unit and oversaw an international team delivering more than US$300 million in microgrid and distributed energy programs. Her work focused on long-duration storage integration, advanced DER value-stacking, and technical frameworks to support one of the world’s most ambitious greenfield energy systems.
Prior to her work in the GCC, Ms. O’Mullane founded Infinet Energy Analytics, advising investment funds, retailers and public agencies on renewable energy strategy, financial structuring and optimisation of DER/VPP portfolios. Earlier in her career, she held leadership and advisory roles across AEMO, EY, Palisade Asset Management, PIMS and Jemena — one of the State of Victoria’s major electricity and gas distribution network service providers. Across these organisations she contributed to national regulatory reform, renewable integration strategies, tariff and pricing model development, and optimisation of large-scale infrastructure portfolios.
Ms. O’Mullane’s expertise spans long-duration storage, microgrids, DER interoperability and codes/standards development, as well as techno-economic modelling to maximise project IRR and system-wide value. At ENOWA she directed the creation of new DER Codes and Standards, delivered high-value project pipelines with minimum 9–10% IRRs, and partnered with global technology leaders — including EPRI and advanced optimisation platform providers — to evaluate system performance and VPP architectures. She also led programs achieving more than A$90 million in capital optimisation in earlier roles across network, regulatory and investment environments.
With a background that bridges system operations, distribution network operations, and institutional investment management, Ms. O’Mullane brings a uniquely integrated commercial, regulatory and technical lens to hydrogen-enabled distributed energy, microgrid deployment and the transition to flexible, decentralised power systems. She has advised executive leadership teams, government agencies and international investors, and is recognised for her ability to translate complex energy-system challenges into commercially grounded, scalable solutions.
