What Mavir does

MAVIR ZRt. (MAVIR Magyar Villamosenergia-ipari Átviteli Rendszerirányító ZRt.) is the designated Transmission System Operator (TSO) for Hungary, operating under statutory license from the Hungarian Energy and Utilities Regulatory Authority (MEKH). The company owns and operates the entire Hungarian high-voltage electricity transmission network — approximately 3,300 km of lines across 120 kV, 220 kV, 400 kV and 750 kV voltage levels, together with 40+ substations — and is the single legally mandated counterparty for all entities that generate, trade, distribute or consume electricity in Hungary. MAVIR is responsible for real-time system balancing, frequency and voltage control, procurement of system services (FCR, aFRR, mFRR, RR, voltage support, black start), cross-border capacity allocation, and administration of renewable energy support schemes (KÁT, premium, storage).

MAVIR's core technology stack centers on real-time transmission network management (SCADA/EMS), day-ahead and intraday electricity market operation (XBID and intraday/flow-based coupling), balancing market platforms, metering and imbalance settlement, grid planning and network calculation tools, and the OVRAM accredited relay protection laboratory. The group holds minority/equity stakes in TSCNET (regional TSO coordination), JAO (joint allocation office), and (until restructuring) CEEGEX (gas exchange), and wholly owns ADEX Group (wholesale electricity trading/brokerage) and M-IT Services (IT systems for the energy sector). The company's European footprint is delivered through ENTSO-E membership and active participation in EU-wide balancing platforms (MARI, PICASSO) and market coupling (AHC, XBID, day-ahead interim coupling).

MAVIR's business model is a regulated monopoly with no commercial sales motion. Revenue is generated through (i) regulated transmission tariffs set by MEKH and charged to all grid users for network access, (ii) settlement of balancing and system services (mFRR, aFRR, FCR), (iii) transaction fees from organized market operations (day-ahead, intraday, balancing) via ADEX/CEEGEX-related platforms, (iv) connection and grid usage fees per the published Business Code, and (v) administration of renewable support schemes. Pricing is non-discretionary and tariff-based; the customer base encompasses all Hungarian electricity market participants — power plants, DSOs, Balance Responsible Parties (BRPs), Balance Service Providers (BSPs), traders and large industrial consumers — a base that is captive by statute.

Revenue model

1. Transmission tariff revenue (regulated): Revenue generated through regulated transmission tariffs charged to all users of the transmission network (generators, traders, distribution companies) for grid access and electricity transmission. Tariffs are set by MEKH (Hungarian Energy and Utilities Regulatory Authority). This is the primary revenue stream for a TSO and constitutes the bulk of MAVIR's income.
2. System services procurement and settlement: MAVIR procures balancing and system services (mFRR, aFRR, FCR, voltage regulation, black start) from market participants and settles imbalances for balance responsible parties. Revenue is cost-reflective and regulated.
3. Market operation fees (CEEGEX, HUPX): Through subsidiaries CEEGEX (natural gas market operator) and ADEX Group, MAVIR generates fees from market operation including day-ahead, intraday, and balancing market platforms.
4. Connection and grid usage fees: Fees for new grid connections, capacity allocation, and network usage charged according to published connection conditions and the Business Code (Üzletszabályzat).
5. Renewable support scheme administration: Administration of KÁT (mandatory purchase), Premium, and Storage support schemes for renewable energy producers, including settlement and risk management.
