CBAM squeezes EPCG export earnings, underscoring the financial risk of coal-heavy power

Montenegro’s state utility Elektroprivreda Crne Gore (EPCG) has entered 2026 under direct financial pressure from the EU’s carbon border framework, with the first measurable hit showing up in its export revenues. The early signal matters for investors because it ties carbon-cost mechanics to real earnings—at a time when EPCG’s ability to adjust prices at home is constrained.

In the first quarter alone, EPCG recorded a €13 million reduction in revenues linked to the implementation of the EU carbon border framework, despite strong electricity sales and favourable hydrological conditions. Management has not framed this as a temporary fluctuation, but as an inflection point that reflects how carbon pricing is increasingly embedded in regional electricity price formation.

CBAM lowers export value while tariffs limit cost recovery

The immediate constraint for EPCG is that passing costs onto consumers is not currently an option. Management indicated that electricity price increases are not being considered, effectively forcing the company to absorb part of the carbon-related revenue erosion internally.

This creates margin compression through two channels: CBAM reduces achievable export prices, while regulated domestic tariffs limit revenue recovery. As a result, profitability becomes more dependent on external variables—such as hydrology and market spreads—rather than on controllable pricing or cost pass-through.

How the mechanism reaches EPCG even without direct EU customs exposure

Even though Montenegro is not exporting into the EU customs system in all cases, CBAM can still transmit indirectly through interconnected regional markets. Electricity prices in EU-linked markets are adjusted to reflect carbon costs, which lowers the selling price available to exporters like EPCG.

In practical terms, that means EPCG sells electricity at a discount relative to what it would have achieved without CBAM—consistent with the €13 million “lost value” reported over three months. Regional dynamics further amplify the effect: electricity prices in the Western Balkans have been reported to trade €20–70/MWh below EU levels, reducing export arbitrage opportunities and reinforcing downward pressure on revenues.

Coal exposure turns carbon pricing into a balance-sheet liability

The structural vulnerability comes from Montenegro’s generation mix. A significant portion of production still relies on coal-fired generation at Pljevlja Thermal Power Plant, leaving EPCG directly exposed to carbon-cost mechanisms.

Under CBAM logic, coal-based electricity carries an embedded carbon cost that can approach EU ETS levels of €70–80 per tonne of CO₂—far higher than what domestic pricing frameworks typically imply. That widens competitiveness gaps between coal generation and renewable or low-emission output within an increasingly carbon-priced European market.

EPCG’s response: reroute exports now, pivot assets over time

EPCG’s short-term response is tactical: redirect exports toward non-EU regional markets where CBAM does not apply and limit exposure to EU-linked price penalties. However, avoiding CBAM does not automatically restore margins because regional markets are generally lower-priced and more volatile.

The longer-term response is already visible in its investment pipeline. The company is advancing commissioning of the Gvozd wind farm, developing three large solar power plants, and preparing documentation for the Kruševo hydro project. The shift points to a transition driven not only by policy alignment but by direct financial necessity as legacy coal assets face tighter margin conditions.

CBAM compounds other operational pressures

The earnings squeeze also interacts with recent operational shocks. In 2025, EPCG was forced to import 1,341 GWh of electricity worth €142 million due largely to an extended outage of Pljevlja and weak hydrology. That underscores a dual exposure: import dependency during supply disruptions—often at high prices—and export revenue erosion under CBAM when coal generation dominates.

A transition linked to profitability

The €13 million quarterly impact may be modest relative to broader balance sheets, but its significance lies in what it signals: CBAM is effectively pricing Montenegro’s energy transition delay into market outcomes in real time. Under current conditions, each megawatt-hour exported from coal carries an implicit penalty that cannot be passed through domestically and cannot be fully offset across regional markets.

For EPCG—and for investors assessing credit risk and capital needs—the implication is clear: profitability is increasingly tied to decarbonisation speed. The faster EPCG shifts its generation mix toward renewables and flexible assets, the better positioned it may be to restore export competitiveness within a European electricity market that is moving deeper into carbon-cost pricing.
