About
As a pioneering and resourceful renewable energy and BESS specialist, I bring a strong track record of project management across a broad range of clean energy assets, including utility-scale solar and wind, distributed energy systems (cogeneration, trigeneration, and hybrid plants), and battery energy storage systems (BESS).Over nearly 20 years in the energy and engineering sectors, I have led the design and modeling of photovoltaic (PV) plants and BESS projects, managed full project development lifecycles, and overseen EPC and O&M contracting and budgeting, with a solid understanding of commercial drivers and long-term asset performance. I have delivered and supported projects in Ethiopia, Germany, India, Ireland, Israel, the Netherlands, Namibia, Qatar, Saudi Arabia, South Africa, Oman, the UK, the US, and Turkey, and have provided technical consultancy on the deployment and integration of energy storage systems.My technical background is complemented by strong academic credentials, including a PhD in Energy Technologies focused on distributed generation, a Master’s degree in Environmental and Nuclear Engineering, and additional qualifications such as an Energy Manager certification, Project Management certification, MBA, and a wide range of law and energy-related courses.With this combination of hands-on experience and formal training, I help organizations deliver robust, bankable, and efficient renewable and storage projects. I am known as an energy expert who is motivated by complex challenges, resilient in the face of obstacles, and committed to high-quality outcomes for all stakeholders.
