Who We Are

By reducing our reliance on fossil fuels through every site we develop, we are supporting the delivery of cleaner energy and lower costs for everyone. This is the future we’re building for generations to come.

Powering a Sustainable Future

Driven by a vision of a greener future, Harmony Energy has evolved into a global operation of developing, owning and operating utility-scale battery energy storage, solar farms and wind assets across the globe.

Our strong track record is built on a team of creators, pioneers and specialists. It’s our responsibility to channel our expertise and passion into accelerating the transition to a sustainable energy system.

Our projects work in harmony with nature and the local community, through setting new standards with biodiversity initiatives, community funds, and cutting-edge technology to ensure safety and sustainability at every site.

Whether you’re a landowner, investor, developer, or simply curious about the future of renewable energy, we invite you to join us on this journey of powering a sustainable future.
