Montenegro has signed grid-connection contracts covering around 3 GW of renewable projects, according to transmission planning information. The contracted pipeline is described as several times larger than the country’s current peak demand. The development focus is shifting toward transmission, balancing and export capacity as the grid bottleneck becomes more prominent.
CGES, Montenegro’s transmission operator, said developers have expressed interest in about 7 GW of potential connections. Approximately 5 GW of projects have progressed through connection studies. Contracts have already been signed for roughly 3 GW, with solar representing the majority of the contracted capacity.
From connection studies to contracted renewable capacity
The connection figures indicate a larger executable renewable pipeline than previously visible in public reporting. For Montenegro, the key constraint is increasingly framed as system capability to absorb, balance and export generation rather than investor demand for solar and wind. With a relatively small domestic market, several gigawatts of new renewable output cannot be accommodated through local consumption alone.
This shift increases the importance of cross-border access for project bankability. Interconnection arrangements are therefore central to whether contracted capacity can translate into deliverable generation.
Interconnections with Serbia, Bosnia, Albania and Kosovo
Montenegro is connected with Serbia, Bosnia and Herzegovina, Albania and Kosovo. In addition, an undersea cable links Montenegro to Italy, providing direct access to a large EU electricity market. The Italy interconnector could become more significant if even part of the contracted pipeline reaches operation.
Export capacity alone is not expected to address all constraints associated with new renewables. Solar output across Southeast Europe is described as becoming increasingly correlated, which can lead Montenegro to generate its largest surpluses at the same time as neighbouring markets.
Price impacts and flexibility requirements
If regional surpluses coincide, prices can be depressed and the value of cross-border sales can be reduced. The need for flexibility therefore extends beyond interconnection capacity. Storage, hydropower optimisation and flexible contracting are highlighted as mechanisms that can support system operation as more solar capacity comes online.
Montenegro’s existing hydro base is described as providing an advantage compared with systems dominated by solar. Hydropower can be held back during periods of abundant PV production and dispatched when regional prices rise. Batteries are also cited as an additional source of flexibility alongside hydropower dispatch.
Grid reinforcement pressure on CGES
The larger contracted pipeline increases pressure on CGES to reinforce substations, transmission lines and system-control infrastructure. Connection contracts are described as commercially valuable only when the grid can physically accommodate the projects. A contracted pipeline of 3 GW is therefore presented as both an investment opportunity and an infrastructure challenge for network expansion.
The development phase is characterised as moving beyond additional project announcements toward turning already contracted capacity into bankable generation. This requires sufficient grid capability, storage resources and export capacity to support delivery from the contracted renewable portfolio.
