Dr Mike Musil, CEO

Dear Valued Partners and Colleagues,

As the CEO of Exergy Power Systems, I am proud to be part of an organisation that plays a crucial role in shaping a sustainable future for our planet. In today's rapidly evolving energy landscape, the demand for responsible and innovative solutions is more pressing than ever before.

Our mission is straightforward: To help large-scale power consumers and grid operators achieve their net-zero targets by integrating advanced battery energy storage systems (BESS) into their existing facilities with the help of our Energy Management Systems (EMS). Every project we undertake is a step forward in our commitment to backing up sustainability and driving innovation in the energy sector.

Born in Tokyo and now serving clients around the globe, we have a unique perspective on both the challenges and opportunities presented by the shift towards renewable energy. Our focus on the Irish and UK markets, areas with high renewable power intake, allows us to test, refine, and enhance our solutions. We are determined to replicate the success of these projects in Japan and beyond.

To our investors and potential clients, I want to express my gratitude for your trust and support. Your belief in our mission fuels our resolve to continue making strides in our field.

At Exergy Power Systems, we do more than just produce energy storage systems. We create opportunities for large-scale power consumers and producers to meet their sustainability goals and help them monetise their flexibility in the energy markets. We contribute to a cleaner, greener planet.

Thank you for joining us on this exciting journey. We look forward to continuing our work, pushing the boundaries of what's possible, and driving the change we wish to see in the world.

Best Regards,

Dr Mike Musil,
CEO, Exergy Power Systems
