Renewable balancing built on 15 years of operating experience. At fees the incumbents can't match.
TSOHAR was founded in Switzerland by Grigorii Toulskii, who previously founded and exited two European renewable trading ventures. We focus on imbalance management and intraday optimization for wind and solar portfolios across Germany and the Netherlands. Our infrastructure is automated end-to-end — no trading floors, no legacy IT — so the cost we save translates directly into lower fees for asset owners.

Grigorii Toulskii — Founder & Managing Director
Grigorii has spent 15 years building and operating in European power markets. Two prior renewable energy trading ventures — both founded, scaled, and exited successfully.
