Montenegro’s three main electricity companies are moving ahead with plans for a joint energy-sector data centre in Nikšić, launching a feasibility and design process that could turn part of the former Željezara industrial complex into critical digital infrastructure.
State power utility EPCG, transmission-system operator CGES and distribution company CEDIS plan to finance the project jointly.
A public call is under way for preparation of a feasibility study and conceptual and technical documentation, which will determine the centre’s capacity, investment value, construction phases and operating model.
The project would consolidate and protect data and information-technology infrastructure used across Montenegro’s electricity system.
It could also create commercial capacity for external customers, potentially turning the facility into a broader data-centre business rather than an exclusively internal utility asset.
That gives the project significance beyond routine IT investment.
Electricity systems are becoming increasingly dependent on digital infrastructure as grids integrate renewable generation, battery storage, smart meters, automated substations and increasingly complex cross-border trading.
For EPCG, CGES and CEDIS, data security and system resilience are therefore becoming operational issues comparable with conventional power infrastructure.
The proposed centre could host applications covering grid management, meter data, electricity trading, asset monitoring and other critical systems.
CGES operates Montenegro’s transmission network and international connections, while CEDIS manages the distribution system and EPCG remains the country’s dominant generator and supplier.
Centralising some infrastructure could reduce duplication and create common standards for cybersecurity, backup and disaster recovery.
The three companies signed a letter of intent in March 2025, making the current procurement a step from strategic concept toward a potential investment decision.
No final capital expenditure figure has yet been set.
That will depend partly on whether the centre is designed only for electricity-sector requirements or includes larger commercial hosting capacity.
The second model could strengthen the investment case.
Montenegro’s demand for secure digital infrastructure is likely to increase as banks, public institutions, telecommunications companies and private businesses move more data into cloud-based and remotely managed systems.
A domestic facility capable of meeting high security and uptime standards could retain some of that demand within Montenegro rather than relying heavily on data centres elsewhere in Europe.
Nikšić also offers potential advantages as a location.
The Željezara complex provides a large industrial site with existing energy infrastructure and land that EPCG has been seeking to put to new economic use.
Reliable electricity supply is one of the largest operating requirements for data centres.
Locating the project within an energy-industrial complex could make grid connection and future renewable-power integration easier than at a greenfield urban site.
It would also add another component to EPCG’s attempt to reposition the former steelworks.
The company has explored multiple energy and industrial activities at Željezara after acquiring the facility, seeking to transform a legacy industrial asset into a diversified energy and production hub.
A data centre would be structurally different from traditional heavy industry.
It would require relatively little physical raw material but substantial power, cooling, connectivity and cybersecurity infrastructure.
That could make the project more compatible with Montenegro’s wider shift toward digital services and lower-emission investment.
Energy consumption will nevertheless be a key issue.
Large data centres can require significant continuous electricity demand, making efficiency, cooling design and power sourcing important to project economics.
If the centre eventually serves commercial customers, the developers could potentially differentiate it through renewable electricity supplied by EPCG.
That could become increasingly valuable as companies seek to reduce the carbon footprint of their digital operations.
The project also has implications for cybersecurity.
Energy infrastructure is increasingly treated as critical national infrastructure because disruptions to digital control systems can affect electricity supply, market operation and public services.
A purpose-built facility could provide stronger physical protection, redundancy and controlled access than dispersed legacy IT infrastructure.
But centralisation also concentrates risk.
The feasibility study will therefore need to assess backup locations, independent power supplies, communications redundancy and disaster-recovery systems.
Commercial viability will be another test.
Montenegro is a small market, and a large data centre would likely need regional or international customers to justify substantial excess capacity.
Location alone will not be enough.
Competitive electricity prices, international fibre connectivity, low latency, data protection standards and high service availability would all be necessary to attract outside users.
The current tender is intended to establish whether those conditions can support a bankable project.
For the three utilities, the strongest rationale may initially remain operational rather than commercial.
Montenegro’s electricity system is becoming more complex, while EU integration is increasing requirements for digital reporting, cybersecurity, system coordination and market connectivity.
A joint data centre could provide shared infrastructure for that transition.
The more ambitious opportunity would be turning the same asset into a commercial platform.
If the feasibility study supports that model, Željezara Nikšić could gain a new role in Montenegro’s energy transition — not as a conventional power plant or heavy industrial site, but as the digital infrastructure supporting both.
