Sinergy Kft. — nearly 20 years of aggregator experience
Sinergy Energiakereskedő Kft., a 100% subsidiary of ALTEO Nyrt., has more than a decade of experience in production management and system-level services. We have been scheduling renewable-based producers for nearly 20 years, and since 2020 we have also performed schedule-group representative functions.
Our company is now responsible for managing a portfolio with a total capacity of nearly 2 000 MW and various technologies (consisting of solar, wind, hydro, biogas, landfill-gas and natural-gas-fired power plants and electricity storage facilities). With the help of our balancing centre, we can put more than 1 200 MW of flexible generation and storage capacity into the service of the Hungarian electricity system every day.

Electricity trading for renewable producers
Flexible service models for offtake of generated power on HUPX at an indexed price.
Its advantages:
- Our partners can determine the ratio of Day Ahead and Intra Day market prices.
- We take over the balancing energy payment obligation from our partners.
- As an aggregator, we also make use of the power plants' balancing capabilities, so our partners can also meet their aFRR obligations.
For every structure we provide:
- full-scope scheduling service
- administration (MEKH reports, MAVIR forecasts)
- near-real-time / daily generation report

Our periodic market reports
Alongside the production management services of ALTEO Energiaszolgáltató Nyrt., we also publish two separate families of market reports. The KÁT Market Reports analyse the market behaviour, volume and pricing processes of renewable and cogeneration power producers operating under the Mandatory Off-take (KÁT) system, based on the publicly available analytics published by MAVIR Magyar Villamosenergia-ipari Átviteli Rendszerirányító ZRt. The ALTEO Storage Market Report presents the market dynamics of the domestic battery electricity storage segment, based on our own trading, balancing and market analyses.
The statements available on the KÁT Market Report page are derived from analytics published by MAVIR, and ALTEO accepts no responsibility for the accuracy of the data. The publications are for information purposes only and do not constitute investment, legal or financial advice.

Regulation Centre
Our group of companies has operated a balancing centre for more than a decade, with the help of which we can put more than 1200 MW of flexible generation and storage capacity into the service of the Hungarian electricity system day after day.
What does this concept involve?
A technical solution that enables several smaller independent generating units, when combined, to appear as one large power plant on the market for electricity and system-level services, thereby realising an extremely efficient, flexible and economical energy generation technology that also meets the challenges and expectations of the 21st century. This system-organisation principle can be extended equally to gas engines and to plants using renewable energy sources, primarily wind and solar power plants.
The ALTEO group also plays a pioneering role in this form of energy generation: its gas engine balancing centre was established at the end of 2013 with an installed capacity of nearly 40 MW, which has since grown to 125 MW. And since May 2023, on a new level, a balancing centre integrating power plants based entirely on renewable energy sources has begun operation, whose controllable capacity already exceeds 1000 MW. While the system has also continuously grown in terms of capacity, based on the experience gained during operation the company has managed to develop a much more balanced, profit-centric and customer-oriented commercial model that entails lower operational and business risk.
Thanks to the business operation based on the fundamental pillars below, the ALTEO group’s balancing centre won the „Balancing Centre of the Year” title announced by the Hungarian Cogeneration Association in 2015.
Six pillars of the business model
Our mission
ALTEO’s mission is to provide a high-value-added, high-quality Balancing Centre service tailored to customers’ needs, and to this end it operates and develops a complex system capable of integrating previously independent market participants, thereby significantly increasing the overall efficiency and profitability of the individual partners and of the system.
