Tupan solar plant cleared for construction in Nikšić area as Montenegro advances its utility-scale PV pipeline

Montenegro’s shift from early-stage renewable planning toward build-ready capacity got a tangible boost in the western region near Nikšić, where the Tupan solar power plant Tupan solar power plant has received full environmental and construction clearance. For investors and lenders, that “green permit” milestone is often where projects stop being speculative and start becoming bankable.

A 90 MW utility-scale project moves from approvals to delivery

The development is being carried out by Podgorica-based S2P Tupan and is designed with an installed capacity of 90 MW. Once completed, it would rank among the largest single-site solar installations in Montenegro’s growing photovoltaic portfolio.

The solar park will be built on approximately 156 hectares, with the layout intended to take advantage of irradiation conditions on the Nikšić plateau—an inland area identified as one of Montenegro’s more favorable zones for solar resources.

Technical documentation cited earlier for the project points to installation of over 129,000 photovoltaic modules. Those panels are described as covering roughly 56% of the total site footprint, implying a relatively high-density configuration consistent with modern fixed-tilt or single-axis tracker approaches used in parts of Southern Europe.

Why permitting matters: de-risking EPC, financing and procurement

The permitting outcome confirms that Tupan has passed several core requirements: an Environmental Impact Assessment (EIA), land-use and spatial planning compliance, and technical grid integration conditions. In practical terms, this reduces regulatory uncertainty at a stage when investors typically focus on whether projects can proceed through engineering, contracting and capital raising.

The clearance effectively places the project on a path that includes EPC structuring, financing negotiations, and preparations for early works and procurement. In regional markets across South East Europe, approvals like these are frequently described as the most significant barrier to realization—so achieving them positions Tupan among the most advanced assets in Montenegro’s pipeline.

How Tupan fits Montenegro’s broader power mix challenges

The project also lands at a moment when Montenegro’s energy system remains shaped by hydropower variability. With annual electricity generation averaging around 3 TWh, a 90 MW solar plant would add meaningful incremental supply. That matters not only for increasing renewables’ share, but also for diversifying generation during dry years when hydro output can fall and imports may rise.

The developers expect contribution across three main objectives: increasing renewables in the national electricity mix; reducing exposure to hydrological volatility; and improving export optionality during periods when solar production peaks.

Ownership structure reflects a familiar Western Balkans model

Tupan is led by S2P Tupan, described as a special-purpose vehicle established in 2023. Ownership is linked to private investors and Swiss-based S2P Electric.

This structure aligns with an approach commonly seen in the Western Balkans: foreign technical capital (covering engineering plus development expertise) combined with local SPV execution and permitting, alongside alignment with EU-style environmental compliance frameworks.

CAPEX benchmarks remain undisclosed while market economics are framed by region-wide ranges

No official CAPEX figure was disclosed for Tupan. However, comparable utility-scale solar projects referenced from across South East Europe suggest typical costs in the range of €0.55–0.75 million per MW. On that basis, an estimated total investment envelope would fall around €50–70 million, depending on factors such as grid connection scope, whether trackers or fixed-tilt systems are used, and how financing is structured.

PPA-related benchmarking cited for current regional pricing points to potential revenue levels in a broad €60–90/MWh range (merchant plus hybrid structures). Under those assumptions, the project could deliver an indicated equity IRR of 9–13% (base case), with additional upside possible if pricing becomes more export-linked or if spreads widen due to congestion dynamics.

Nikšić as a renewable cluster—but grid absorption remains central risk

The Nikšić area is already emerging as part of a wider renewable concentration supported by existing transmission infrastructure and proximity to hydro generation assets. Planned expansion of both solar and wind capacity in western Montenegro further reinforces that regional momentum.

Even so, generation build-out does not automatically translate into delivered power. As highlighted for SEE markets generally, constraints tend to center less on producing electricity than on grid absorption capacity, including curtailment risk during peak solar hours.

This elevates interest in operational solutions such as hybridization (solar paired with BESS), flexible dispatch arrangements, and cross-border export optimization—elements that become increasingly relevant when new PV plants come online at times when output may exceed what local networks can take without intervention.

A permitted asset signals structural change toward finance-ready renewables

Tupan’s approval illustrates several deeper shifts described within Montenegro’s energy sector:

• A move from state-led toward private-led RES deployment, with projects increasingly driven by private developers rather than solely EPCG-led initiatives;

• The emergence of a bankable solar pipeline:</u0026nbsp;with permitting milestones achieved, projects like Tupan become viable candidates for project finance, multilateral funding and strategic investor entry;

Taken together, approval of the 90 MW Tupan solar plant would move Montenegro further into an execution phase where renewable additions are no longer only conceptual policy initiatives. Instead they become fully permitted infrastructure assets intended to influence both domestic generation mix outcomes—and how electricity may position regionally over time.
