Konstantinos Athanasopoulos and Sympower bring Demand Response innovation to Greece, a smart energy solution that balances electricity supply and demand by shifting or reducing consumption, driving the green energy transition and supporting grid stability.
In one sentence, tell us what you do!
I lead Sympower’s Greek office, responsible for commercial agreements, team management (sales & support), and daily operations coordination.
How did you get started in this field and what inspired you?
I am an Electrical Engineer with a passion for sales and challenges. I have always been interested in the energy sector, and Sympower’s activity in an innovative and fast-growing niche market inspired me to get actively involved. The chance to contribute to something with real impact, both on the market and on sustainability, was decisive for me.
What is the greatest impact you want your work to have on the world?
Through my work, I want to contribute to the green energy transition, grid stability, and reduced energy costs for industries, enhancing their competitiveness — with the ultimate goal of lowering electricity prices for everyone in the long term.
Tell us about a recent project or achievement you are proud of!
At Sympower, we successfully introduced Demand Response to the Greek energy market, now representing over 300MW of flexible industrial loads. From zero participation, Demand Response today covers 10% of Greece’s balancing services. We are considered pioneers and market leaders, both in terms of capacity and in active daily participation.
The Impact Hub Athens & You
What brought you to Impact Hub Athens and what does this community mean to you?
When searching for a headquarters for Sympower’s Greek office, we discovered Impact Hub. From the very first moment, we felt that its philosophy and environment aligned with our own culture: coexistence, participation, and support for a sustainable future. A coworking environment with real substance.
Is there someone/something within Impact Hub that has inspired or supported you?
The culture of Impact Hub and the daily coexistence within its spaces – from the offices to the balcony and the courtyard – create an inspiring environment. Every day offers us inspiration for creation, collaboration, and growth, based on shared values for a sustainable and participatory future.
How can the community support you or connect with you?
Sympower has now grown significantly. Our goal – and mine personally – is to give back to the Impact Hub community the support we received, empowering other members with ideas, vision, and willingness to work and create. We want to contribute tangibly to their growth.
