Introduction
Energy generation today is no longer merely a question of capacity: flexibility, efficiency and the ability to adapt quickly are at least as important. ALTEO’s heat and electricity generation activities are built on this approach: with our diversified power plant portfolio we simultaneously support security of supply, the servicing of changing market demands and the realisation of more sustainable energy generation.
Our goal is to provide our partners with a stable, predictable and future-proof energy generation background — while actively contributing to the energy transition and more sustainable operation.

Did you know?
Budapest for a whole year
In 2024 we produced as much electricity as a city the size of Budapest uses for all its electrical devices over an entire year.
Debrecen for a whole winter
The heat energy produced would be enough to heat the homes of Debrecen throughout the entire year.
