Simon Andrew Coulson
Aura power developments co-founder and CEO
When Aistis became CEO of the Association, I was on the Board of organization as Managing Director of JSC Renerga. At that time, the Association lacked influence and impact. Aistis' leadership brought significant change. The wind industry’s voice became central in shaping energy legislation, establishing wind energy as a key part of Lithuania’s energy mix.He maintained strong relations with the Ministry of Energy and Parliament committees while balancing diverse industry interests within the Association. Membership grew from 17 to 37 in five years, and today, with over 50 members, much of the Association's growth and influence is thanks to Aistis' dedication and professionalism.
