A large-scale solar development in western Montenegro has moved into the execution phase, with the Tupan solar power plant near Nikšić receiving full environmental and construction clearance, marking one of the most advanced private renewable projects currently progressing in the country.
The project, developed by Podgorica-based S2P Tupan, is designed with an installed capacity of 90 MW, positioning it among the largest single-site solar installations in Montenegro’s emerging photovoltaic portfolio.
The solar park will be built across approximately 156 hectares of land, reflecting a utility-scale layout optimized for irradiation conditions in the Nikšić plateau, one of the country’s more favourable inland solar zones.
From a technical standpoint, earlier project documentation indicates the installation of over 129,000 photovoltaic modules, covering roughly 56% of the total site footprint, suggesting a relatively high-density configuration aligned with modern fixed-tilt or single-axis tracker layouts used in Southern Europe.
Project positioning within Montenegro’s energy transition
The approval of the Tupan project confirms a broader structural shift in Montenegro’s energy strategy, where utility-scale solar is transitioning from pilot-scale deployment toward bankable infrastructure assets.
With Montenegro’s annual electricity generation averaging around 3 TWh, a 90 MW solar plantrepresents a meaningful incremental addition, particularly in diversifying a system still heavily dependent on hydropower and imported electricity during dry years.
The project is expected to contribute to:
• Increased share of renewables in the national mix
• Reduced exposure to hydrological volatility
• Improved export optionality during peak solar generation periods
Ownership and development structure
The project is being led by S2P Tupan, a relatively new special-purpose vehicle established in 2023, with ownership linked to:
• Private investors
• Swiss-based S2P Electric
This ownership structure reflects a recurring model in the Western Balkans:
• Foreign technical capital (engineering + development expertise)
• Local SPV execution and permitting
• Alignment with EU environmental compliance frameworks
Permitting milestone: From EIA to construction
The issuance of the “green permit” confirms that the project has successfully passed:
• Environmental Impact Assessment (EIA)
• Land-use and spatial planning compliance
• Technical grid integration conditions
This is a critical de-risking step, effectively moving the project into:
• EPC structuring
• Financing negotiations
• Early works and procurement
In the regional context, such approvals often represent the single largest barrier to project realization, meaning Tupan is now positioned among the most advanced solar assets in Montenegro’s pipeline.
CAPEX and market benchmarking
While official CAPEX has not been disclosed, comparable projects in the SEE region suggest:
• Utility-scale solar CAPEX:
€0.55–0.75 million/MW
This implies an estimated investment envelope of:
• €50–70 million total project value
Depending on:
• Grid connection scope
• Tracker vs fixed-tilt configuration
• Financing structure
At current regional PPA benchmarks:
• €60–90/MWh range (merchant + hybrid structures)
The project could deliver:
• Equity IRR: 9–13% (base case)
• Higher upside under export-linked pricing or congestion-driven spreads
Grid and system integration context
The Nikšić area is already emerging as a renewable cluster, supported by:
• Existing transmission infrastructure
• Proximity to hydro generation assets
• Planned expansion of solar and wind capacity in western Montenegro
However, as with most SEE markets, the key constraint will not be generation—but:
• Grid absorption capacity
• Curtailment risk during peak solar hours
This places increasing importance on:
• Hybridization (solar + BESS)
• Flexible dispatch arrangements
• Cross-border export optimization
The Tupan project signals several deeper structural shifts in Montenegro’s energy sector:
1. Transition from state-led to private-led RES deployment
Projects are increasingly driven by private developers rather than solely EPCG-led initiatives.
2. Emergence of bankable solar pipeline
With permitting milestones achieved, projects like Tupan become viable for:
• Project finance
• Multilateral funding
• Strategic investor entry
3. Shift toward export-oriented generation model
Given Montenegro’s relatively small domestic demand, new capacity is increasingly:
• Positioned for regional trading
• Linked to broader SEE electricity flows
4. Foundation for hybrid and storage integration
Future phases are likely to include:
• Battery storage
• Grid services participation
• PPA-linked flexibility mechanisms
The approval of the 90 MW Tupan solar plant effectively moves Montenegro into a new phase of renewable deployment, where projects are no longer conceptual or policy-driven, but fully permitted, finance-ready infrastructure assets capable of reshaping the country’s generation mix and regional electricity positioning.
