Electricity Trading
After the successful entry into the natural gas trading market, based on the relevant experience gained during multiple projects, and seeing the increasing market demand for integrated energy trading offers, Milleyson holdings ltd. has expanded its activities into the field of Electricity Trading. Our goal is to broaden our energy trading product portfolio and to better exploit our established trading infrastructure.
In 2022, we obtained the official electricity trading licence. The connection to the balancing group system has been established for the start of electricity trading activities, the development of the procurement channels, and, last but not least, the connection to the balancing group system provided by the transmission system operator for the settlement of transactions and deliveries. In the same year, the construction of the customer portfolio started, with trading gas in October and electricity from January 2023 to competitive players. Our vision was to extend our activities to the retail market to fully supply our customers.
During the development phase, at Milleyson Holdings Ltd., we have acquired full membership of the Hungarian Power Exchange (HUPX) and the Joint Allocation Office (JAO), the European cross-border capacity sales platform.
Our company holds an electricity trading licence issued by the Hungarian energy and public utility regulatory office and has its balance sheet. As an experienced trader, we can provide energy to your business based on pricing that meets the current market needs.
At Milleyson Holdings, we have a diversified energy trading portfolio, of which the provision of innovative electricity services is an integral part. As a licenced electricity trader, we can put together energy packages on favourable terms firsthand, and provide these to our customers on either a short or long-term basis.
To provide full services all across the country, we have concluded framework agreements with multiple providers in Hungary, such as: Magyar Villamosenergia-ipari Átviteli Rendszerirányító Zrt. (MAVIR), E.ON Észak-dunántúli Áramhálózati Zrt. (E.ON ÉDÁSZ), E.ON Dél-dunántúli Áramhálózati Zrt. (E.ON DÉDÁSZ), ELMŰ Hálózati Kft. (ELMŰ), MVM Émász Áramhálózati Kft. (ÉMÁSZ), MVM Démász Áramhálózati Kft. (DÉMÁSZ), Opus Titász Zrt. (TITÁSZ)

As our company has its balance sheet, we can also provide our customers with the related advanced services. In addition to wholesale trading of natural gas, our company also has a consumer portfolio (small and medium-sized companies) in Hungary.

Aggregator service
The transposition of the EU's Clean Energy Package (CEP) has made it possible for aggregators to enter the domestic electricity market from the 1st of January 2021. In 2023, Milleyson Holdings Ltd. applied for an aggregator licence from the Hungarian Energy and Utility Regulatory Office (MEKH).
The Role of the Aggregator in electricity supply:
- exploit the portfolio potential of existing resources
- improve the accuracy of consumption and generation forecasts
- strengthen participation in balancing regulation
- remove barriers to entry
- provide trading opportunities for smaller players
- allow free movement between balance sheets
The Aggregator provides services to its counterparties that go beyond traditional electricity supply and can remain partially independent from them.
Milleyson Holdings Ltd. intends to participate as much as possible in the areas detailed above and to help its business partners to access flexible services while holding the Aggregator licence.

Balance group services
Milleyson Holdings Ltd. has multiple years of experience in scheduling services for both producers and consumers.
The accuracy of scheduling and balance group management is of paramount importance to ensure the balance of the electricity system and to avoid high balancing energy charges.
Especially for our partners with renewable energy generation, it is of paramount importance to provide the most accurate forecast to avoid penalties imposed by the system operators.
Elements of the Milleyson Holdings Ltd. service:
- variable-rate renewable generation scheduling
- twelve-month generation forecast
- daily and intra-day planning (DA and ID)
- MAVIR settlement management
- regular data reporting
- data input management from inverters

Together with our partners, we design the most convenient service for them within the framework of our present service and, optionally, we can sell the generated energy on the electricity markets in the short and/or long term.
