Montenegro’s proposed Velestovo solar project is progressing through two key development milestones for renewable bankability: transmission access and environmental permitting. The project is described as moving closer to a point where lenders and equity investors can assess it as an executable development rather than a concept.
The project is being developed through SE Velestovo and is associated with Nu Energy. It envisages solar capacity of up to approximately 60 MWp, combined with battery energy storage and the transmission infrastructure needed to connect to Montenegro’s electricity system. The estimated investment is approximately €50 million.
The battery’s final power and energy capacity has not been disclosed. The inclusion of storage from the development stage is stated as strategically important for the project’s progression.
Grid-connection agreement with CGES
On 19 August, CGES and Nu Energy signed the grid-connection agreement for the Velestovo project. Days later, the project company advanced the environmental process covering the solar plant and its associated transmission line.
Neither the grid-connection milestone nor the environmental process completion guarantees that construction will proceed. However, together they are described as moving Velestovo materially closer to a stage where financing parties can evaluate it as a deliverable project.
Transmission access as a project filter in Montenegro
In Montenegro, grid connection is identified as one of the primary filters affecting which wind and solar projects can reach construction. The electricity system is described as small, while the country has a substantial pipeline of proposed renewable capacity.
A project without defined transmission access may still have strong irradiation potential and land rights but limited investment value. Connection arrangements are therefore presented as increasingly scarce assets within the development pipeline.
BESS integration tied to regional market exposure
Velestovo is also described as reflecting a broader shift in Montenegro’s solar market toward including batteries from the outset. Batteries are increasingly treated as part of renewable developments rather than optional additions at later stages.
The rationale cited is Montenegro’s interconnection with neighbouring Balkan markets and, critically, with Italy via an undersea electricity interconnector. This setup provides electricity produced in Montenegro access to markets that may have different hourly price structures.
Solar output is concentrated around daylight periods that are also described as experiencing price pressure across Southeast Europe. A battery can change the commercial profile by retaining part of generation during peak output periods and discharging later when regional prices are stronger.
The source also notes that storage can reduce imbalance exposure. While solar forecasting is relatively predictable compared with wind, cloud movements and transmission conditions can still create deviations between scheduled and actual output; BESS can absorb some of those deviations to support a more controllable export profile.
Lender considerations for battery revenue streams
The value of storage may increase if Montenegro expands balancing-market participation and regional market integration. For lenders, the challenge highlighted is identifying which battery revenues are sufficiently dependable for inclusion in debt sizing.
Pure merchant arbitrage is described as volatile. Balancing services are presented as an additional potential income stream, but their contribution depends on market rules and future competition.
The most conservative financing approach described treats BESS primarily as a tool for improving solar captured prices and reducing imbalance costs, with other services providing upside. In that framework, the transmission location is stated as central to determining how effectively price signals from regional markets, including potentially Italy, can be accessed .
Development sequencing for environmental approval and flexibility
Velestovo is also said to align with Montenegro’s broader strategic direction for its power system. The country has hydropower, prospective wind and solar resources, regional interconnections, and potential pumped storage.
The combination is described as enabling an electricity system focused not only on renewable generation but also on flexibility and export optimisation. Even so, individual projects still need to pass difficult development stages including environmental permitting, land arrangements, geotechnical design, transmission engineering, financing and procurement .
The project sequence for Velestovo is described as securing grid access while progressing environmental approval alongside integrating storage from the beginning. Its importance is stated as going beyond 60 MWp, with Velestovo positioned as one of Montenegro’s first clear examples of a solar-plus-storage project designed around regional electricity-market economics rather than simple renewable generation .
