MEPSO

What MEPSO does

MEPSO (AD Makedonski Elektroprenosni Sistem Operator) is the state-owned joint-stock company designated as the sole electricity transmission system operator of the Republic of North Macedonia, established in 2005 through the transformation of Macedonian Power Plants AD. The company operates and manages the national high-voltage transmission grid comprising more than 2,200 km of overhead lines at 35, 110, 220, and 400 kV voltage levels, supported by over 7,040 towers and 50+ substations (14 owned outright, the remainder jointly held with distribution system operators) with combined installed transformer capacity of 6,417 MVA. MEPSO also runs a 400 km Optical Ground Wire (OPGW) fiber optic telecommunications network integrated into its transmission lines for grid-to-control-center data exchange, connected to neighboring power systems in Bulgaria and Greece. Operational control is delivered through SCADA/EMS, SACS substation automation, and AMR/MDM meter data management systems.

MEPSO's commercial product surface centers on the Market Management System (MMS), a six-module platform (Master Data, Auction, Nomination, Dispatching, Balancing, Settlement) that operates 24/7 with XML-based data exchange per ENTSO-E standards and connects to the SCADA system. The MMS handles scheduling, balancing capacity and energy auctions (FCR, aFRR, mFRR), dispatching, and settlement for the Macedonian wholesale and balancing markets. The company also operates the SCADA/EMS real-time energy management system and participates in two EU Horizon 2020 research consortia—CROSSBOW (24 organizations, 13 countries) and TRINITY (19 organizations)—developing cross-border renewable energy management and TSO market coupling tools for Southeast Europe. Major infrastructure projects under development include the 400 kV Bitola–Elbasan cross-border interconnection with Albania (part of EU Corridor 8) and the Southeast Regional Transmission Network Strengthening project for renewable energy integration in southeastern North Macedonia.

Revenue is generated through regulated transmission tariffs set by the Energy Regulatory Commission (Komisioni Rregullator i Energjetikës) based on MEPSO's operational costs, paid by distribution system operators (principally EVN Macedonia), power generators (principally ELEM), and direct industrial consumers including ArcelorMittal, Makstil, OKTA, Bučim, Feni Industry, Usje Jugohrom-Feroalloys, Legurat e Shkupit, and Macedonian Railways. Cross-border wheeling and balance market activities with neighboring countries (Bulgaria, Greece, Serbia, Albania, Kosovo) supplement domestic tariff revenue. The company holds two core wholly-owned operating subsidiaries: TGO (Transmission Grid Operator), which maintains the physical transmission infrastructure, and OEPS/ETSO (Electricity Transmission System Operator), which manages dispatching, market organization, balance management, and SCADA/EMS systems. Capital expenditure is supported by loans from the European Investment Bank, World Bank, and EBRD, plus WBIF grants and Horizon 2020 project funding, with COWI (Denmark) engaged as a consulting consortium lead on the Bitola–Elbasan feasibility study. MEPSO is an ENTSO-E member and operates under EU-aligned regulatory frameworks.

Direct peers

• ESO EAD (Electricity System Operator of Bulgaria): National TSO of Bulgaria, directly comparable to MEPSO as a neighboring SEE transmission system operator. Both operate ENTSO-E-aligned grids, manage cross-border interconnectors, and participate in the same regional market coupling initiatives.
• IPTO (Independent Power Transmission Operator of Greece): Greek national TSO operating a high-voltage transmission network interconnected with MEPSO across the shared border. Comparable in regulatory model (EU-aligned, ENTSO-E member), asset class (400/110 kV lines, substations), and cross-border coordination role.
• EMS (Elektromreža Srbije): Serbian national TSO, a Western Balkans peer operating under similar EU-aligned frameworks and interconnected directly with MEPSO. Comparable scale, governance model (state-owned), and involvement in regional balancing and market coupling projects.
• KOSTT (Transmission, System and Market Operator of Kosovo): Kosovo's TSO with direct cross-border interconnection to MEPSO and overlapping participation in CROSSBOW/TRINITY consortia. Highly comparable in asset profile (400/110 kV transmission, substation operation) and small-market, single-TSO monopoly structure.
• OST (Operatori i Sistemit te Transmetimit, Albania): Albanian national TSO and counterparty for the Bitola-Elbasan 400 kV interconnection project led by MEPSO. Directly comparable as a Western Balkans TSO with similar regulatory, scale, and EU-integration profile.
• ELES (Elektro-Slovenija): Slovenian national TSO operating a small, ENTSO-E-aligned transmission network comparable in scale and regulatory structure to MEPSO. Strong reference point for asset-light, EU-converged TSO operations in the region.
• HOPS (Hrvatski operator prijenosnog sustava): Croatian TSO managing a 400/110 kV transmission network interconnected with SEE neighbors. Comparable as a regional EU-member TSO with similar ENTSO-E compliance and cross-border coordination responsibilities.
• NOS BiH (Independent System Operator in Bosnia and Herzegovina): Bosnian TSO that, like MEPSO, operates under Western Balkans regulatory frameworks with ENTSO-E alignment and direct SEE regional coordination. Comparable in scale, asset mix, and EU-funded modernization profile.

Broad incumbents

• Transelectrica (Romania): Larger SEE TSO serving Romania with ENTSO-E membership and similar regulated-monopoly model. Comparable as a broader regional incumbent whose operations and cross-border projects provide benchmarks for SEE transmission expansion.

Others

• ELEM (Elektrostopanstvo na Makedonija): North Macedonian state-owned power generator and joint CROSSBOW consortium partner with MEPSO. Highly adjacent: not a TSO but the dominant domestic generation counterpart whose output flows through MEPSO's transmission network, making it the key upstream value-chain participant.
