Balance groups play a key role in the operation of the Hungarian electricity system, ensuring that power generation and consumption are always in balance. The purpose of balance groups is to make the energy consumption of their members more predictable and efficient, and to settle any over- or under-consumption or generation within a given period. This ensures a stable and reliable operation of the electricity system, while minimizing the costs of balancing energy.

According to Section 3 (46) of Act No. LXXXVI of 2007, a balance group is:
“A clearing group of one or more members established to regulate liability relationships in relation to the causal determination and settlement of balancing energy use and the performance of related tasks.”

The operation of balance groups and the tasks of balance responsible parties (BRP) are specified in the prevailing National Network Code (NÜKSZ) approved by the Hungarian Energy and Public Utility Regulatory Authority.

The largest balance group in the Hungarian electricity system is operated by MVM ONEnergy Ltd. Through MVM Next Energy Trading Ltd., the company supplies electricity to a significant part of the Hungarian population. The members of MVM ONEnergy Ltd.'s balance group comprise subsidiaries of the MVM Group as well as external market players. In addition to generators, over 60,000 competitive market consumers are included, thereby making MVM ONEnergy Ltd. the largest domestic commercial licensee.

Joining the balance group offers numerous advantages: in addition to the security arising from many years of operational experience, the large number of customers and energy turnover result in a significant balancing effect. This reduces the amount of balancing energy required and minimizes the associated costs. In addition, MVM ONEnergy Ltd. contributes to the stable operation of the Hungarian electricity system and to the continuous and smooth energy supply through its system-level services.

Within the company, the daily operational BRP tasks are performed by the Scheduling and Balance Group Management Department (MIO). MIO not only manages MVM ONEnergy Ltd.’s Hungarian balance group, but also performs BRP tasks for other foreign balance groups belonging to the MVM Group.
