Montenegro’s proposed Velestovo solar project is progressing through two milestones highlighted as key for renewable bankability: transmission access and environmental permitting. The development is being carried out via SE Velestovo with Nu Energy associated with the project.
The plan envisages up to approximately 60 MWp of solar capacity alongside battery energy storage. It also includes the transmission infrastructure needed to connect the plant to Montenegro’s electricity system. The estimated total investment is approximately €50 million.
The battery’s final power and energy capacity has not been disclosed. However, storage is included from the development stage, according to the project description. On 19 August, CGES and Nu Energy signed the grid-connection agreement.
Grid-connection agreement and environmental process progress
Days after the grid-connection signing, the project company advanced the environmental process for the solar plant and its associated transmission line. The environmental steps cover both generation and grid-related works connected to the project.
Neither the grid-connection milestone nor the environmental permitting process guarantees that construction will proceed. Even with both steps underway, lenders and equity investors would still evaluate whether the project can move beyond development status.
Taken together, the two milestones are intended to move Velestovo closer to a point where financiers can assess it as an executable project rather than a concept under development. In Montenegro, this distinction is presented as particularly relevant because of how projects compete for connection capacity.
Transmission access as a key filter in Montenegro’s renewables pipeline
Montenegro has a substantial pipeline of proposed wind and solar capacity. However, the electricity system is described as small, and grid connection is increasingly treated as one of the primary filters for projects reaching construction.
A project without defined transmission access may still have strong irradiation conditions and land arrangements but limited investment value. As a result, connection arrangements are described as becoming a scarce asset for developers seeking bankable outcomes.
Velestovo is also described as reflecting changes in Montenegro’s solar market approach to storage. Batteries are beginning to appear within renewable developments from the outset rather than being added later as optional expansions.
BESS role linked to regional market access and price timing
The shift toward early-stage storage is linked to Montenegro’s interconnections with neighbouring Balkan markets and, critically, Italy via an undersea electricity interconnector. This connectivity provides produced electricity with potential access to markets that may have different hourly price structures.
Solar output is concentrated around daylight periods that increasingly face price pressure across Southeast Europe. Within that context, storage is described as able to alter how electricity is sold by retaining part of output during peak production hours and discharging later when regional prices are stronger.
BESS can also reduce imbalance exposure by absorbing some deviations between scheduled and actual output. Solar forecasting is described as relatively predictable compared with wind, but cloud movements and transmission conditions can still cause differences that affect export profiles.
Lender considerations for battery revenues under market rules
The value of BESS may increase if Montenegro expands balancing-market participation and regional market integration. For lenders, the key issue described is identifying which battery-related revenues are sufficiently dependable for inclusion in debt sizing.
Pure merchant arbitrage is described as volatile. Balancing services may provide additional income but depend on market rules and future competition levels.
A conservative financing approach described for such projects would treat BESS primarily as a tool for improving solar captured prices and reducing imbalance costs. Additional revenue streams from other services would be treated as upside rather than core assumptions in debt structuring.
Transmission location influence on storage economics
The economics of Velestovo’s battery are described as depending on where it connects within the transmission system. If grid access enables effective exposure to regional price signals, including potentially Italian price signals, storage could have greater value than batteries attached to isolated distribution-level projects.
Strategic context for flexibility in Montenegro’s power system
Velestovo is also positioned within Montenegro’s broader strategic direction for its power system mix. The country has hydropower alongside prospective wind and solar capacity, regional interconnections, and potential pumped storage.
This combination supports the possibility of building an electricity system focused not only on renewable generation but also on flexibility and export optimisation. Individual projects still face difficult development stages involving environmental permitting, land arrangements, geotechnical design, transmission engineering, financing and procurement.
The description of Velestovo emphasises that it is moving through what is presented as the right sequence by securing grid access while progressing environmental approval and integrating storage from the beginning. Its significance is stated as extending beyond 60 MWp, with potential relevance for early examples of solar-plus-storage designed around regional electricity-market economics rather than simple renewable generation.
