Responsibly Different.
Impact Electrons Siam (“IES”) was founded in 2011 with the vision to develop and invest in assets that accelerate energy transformation to the decarbonizing Asia Pacific. To date, IES has implemented over 1 GW of renewable energy across the region.
On 22 August 2025, we achieved a historic milestone with the commercial operation of the 600 MW Monsoon Wind Power Project in southern Lao PDR. As Asia’s first cross-border wind farm, it now delivers clean electricity from Laos to Vietnam, strengthening regional connectivity and advancing ASEAN’s decarbonization journey.
With a pipeline of up to 10 GW, IES continues to drive sustainable growth by transforming bold ideas into bankable projects that uplift communities and create lasting impact.
