Believe.
Trust.
Deliver.
Let’s shape tomorrow’s energy, together.
More than electrons
We believe infrastructure should create value far beyond the electrons it delivers.
IES was founded to unlock Asia Pacific’s clean energy potential through new thinking, making energy more affordable and creating lasting value for all stakeholders, with local communities at the heart of how we develop and operate. Today, we are building the sustainable energy and digital infrastructure needed for what comes next.
We see opportunities to create lasting value and uplift communities. We take a long-term view and are comfortable taking on difficult challenges when the outcome can create value for all stakeholders. From Asia’s first cross-border wind project to the next generation of sustainable infrastructure, we bring together governments, communities, lenders and global partners to turn bold ideas into lasting progress, creating clean energy, enabling green infrastructure and building shared prosperity.
