Montenegro’s transmission system operator, Crnogorski elektroprenosni sistem (CGES), is preparing to take on a new €25 million loan from the French Development Agency, marking another step in the country’s ongoing grid modernisation cycle.
The financing, backed by a state guarantee, is earmarked for critical transmission upgrades, including the reconstruction and expansion of the Perućica substation and the installation of a new autotransformer at Pljevlja 2, both key nodes in Montenegro’s high-voltage network.
These investments target structural constraints that have become increasingly visible as the regional power system shifts toward higher shares of renewable generation and cross-border electricity flows. Strengthening transformer capacity and substation resilience directly improves voltage stability and transmission flexibility—two areas where the Western Balkans grid has faced growing operational pressure.
The financing structure reflects a familiar model in Montenegro’s energy sector: international development funding combined with sovereign backing. The government’s willingness to provide guarantees underscores the strategic importance of transmission infrastructure as a regulated natural monopoly with system-wide impact, rather than a purely commercial asset.
The AFD facility also sits within a broader financing framework. Montenegro has been expanding cooperation with the French Development Agency through multi-tranche arrangements that support both infrastructure investment and policy reforms, with previous and parallel programmes extending into areas such as climate policy, renewable integration and institutional capacity building.
For CGES, the loan continues a long-standing pattern of leveraging international lenders—historically including the European Bank for Reconstruction and Development—to fund grid upgrades tied to regional interconnection and system reliability. The current phase of investment is less about expanding capacity from a low base and more about adapting the network to higher volatility, bidirectional flows and integration with EU markets.
The Perućica and Pljevlja nodes are particularly relevant in this context. They sit at the intersection of domestic generation, cross-border exchanges and future renewable inflows, making them critical for maintaining system balance during both high-export and low-demand periods.
What emerges from this financing decision is a clear prioritisation of grid readiness over generation expansion alone. As the region moves toward deeper market coupling with the EU and faces new pressures such as carbon pricing mechanisms and fluctuating export dynamics, transmission infrastructure is becoming the limiting factor for value capture.
The €25 million loan is modest in scale relative to total system needs, but it fits into a broader investment pattern where incremental upgrades collectively determine the system’s ability to absorb renewable capacity, stabilise flows and maintain export competitiveness.
