Montenegro’s state-owned electricity utility, EPCG, has reported that household electricity prices have remained unchanged at the active-energy level since June 2019. This stability comes despite an increase in its retail customer base and fluctuations in wholesale market prices, necessitating enhanced payment discipline to support retail operations.
As of July 2026, EPCG served 415,759 household customers, marking an increase of nearly 18% from 352,815 customers in June 2019. The number of regular payers rose to over 257,985, up from 188,913 during the same timeframe. Consequently, the proportion of households classified as regular payers increased to 62.1%, compared to 53.5% previously.
This improvement is significant for EPCG, as the political sensitivity surrounding Montenegro’s retail electricity market restricts the ability to quickly transfer increased wholesale and generation costs to consumers. The company noted that the active-energy component of household tariffs has not changed since June 2019, despite surges in European electricity prices during various periods.
The focus on operational efficiency, local generation, and effective cash collection has become essential for EPCG. To further encourage timely bill payments, the utility has implemented discounts for customers. Between January and July 2026, EPCG spent approximately €4 million on these discounts, surpassing the €3.6 million budgeted for all of 2019.
While stable tariffs combined with increased discounts typically exert pressure on retail margins, improved bill collection has led to reduced receivables and enhanced cash flow. This is particularly vital for EPCG as it manages financing for generation maintenance, renewable investments, and electricity imports during periods of low domestic production.
The company’s power balance is notably affected by hydrological conditions. Hydropower generally constitutes a large portion of domestic generation; however, production can decline significantly during dry spells, forcing reliance on the Pljevlja coal-fired power plant and regional electricity purchases. EPCG indicated that Pljevlja accounted for around 65% of its electricity production from June to August 2026, highlighting the critical role of domestic thermal generation in managing import exposure.
EPCG estimated that Pljevlja generated roughly 442 GWh during this three-month period, with a market value exceeding €51 million. In comparison, replacing this output through purchases on Hungary’s HUPX market would have cost approximately €57.4 million, excluding cross-border capacity and other expenses.
The link between stable household prices and generation performance is evident; when both hydro and thermal plants operate effectively, EPCG can minimize its reliance on wholesale imports. Conversely, when domestic output declines, maintaining regulated retail prices becomes more challenging and costly.
The expansion of EPCG’s customer base has added complexity to this situation. Since 2019, around 63,000 additional household customers have been added due to population shifts, housing developments, and rising electricity demand. Montenegro has also experienced record summer consumption levels as tourism and real estate development boost seasonal energy needs.
A larger customer base can enhance revenues if billing efficiency is maintained. Therefore, the rise in regular payers serves as a crucial indicator of retail performance beyond mere customer growth. Historically, EPCG has faced significant receivables from households and businesses; thus, payment discipline remains a persistent issue for its balance sheet.
As of early 2026 data, EPCG reported about €175 million in receivables, including over €112 million from households, with a considerable portion of outstanding debts being several years old. While improved payment behavior does not eradicate these legacy receivables, it may prevent further deterioration.
The broader challenge lies in whether EPCG can sustain relatively stable household prices amidst Montenegro’s deeper integration into the European energy market. Factors such as EU accession requirements and carbon pricing are expected to exert additional pressure on the economics of the electricity sector.
The Pljevlja facility will eventually incur higher carbon and environmental costs while EPCG invests in new wind and solar capacity aimed at reducing dependency on coal and imports. Projects like the Gvozd wind complex are anticipated to enhance the generation mix; however, substituting firm thermal output with variable renewables will necessitate investments in grid infrastructure and storage solutions.
This transition implies that households cannot view the prolonged period of stable energy charges separately from the investments needed to modernize the power system. For EPCG, improved payment discipline offers greater financial flexibility as it navigates retail price pressures while expanding capital expenditures.
The increase in regular payers exceeding 62% strengthens cash collection at a time when the company balances rising capital investment demands with maintaining stable retail tariffs amid evolving carbon regulations and market dynamics.
