The Hungarian technology company 4iG is evaluating potential investments in Montenegro’s renewable energy sector, power networks, energy supply, and digital infrastructure. This expansion follows the company’s existing operations in telecommunications through its mobile subsidiary, One Montenegro, which has been active since 2021. The firm aims to enhance its footprint in the Balkan region as it prepares to engage in a government-led data centre project.
4iG indicated that it is assessing various business and investment opportunities in Montenegro as part of a broader strategy to penetrate energy markets across Central and Eastern Europe, including the Western Balkans. The company’s potential initiatives may encompass renewable energy generation, associated grid developments, and solutions for energy supply and digital infrastructure.
In March, Montenegro’s government selected 4iG Group for negotiations regarding the construction of a state data centre and a modernization program for law enforcement agencies. The budget for the law enforcement project is set at €54.25 million, while the financial details for the data centre remain to be finalized. According to 4iG, its international digital-infrastructure subsidiary plans to ensure that the facility meets Tier III certification standards.
In its stock exchange announcement from March, 4iG clarified that while Montenegro had commenced negotiations with the group and its subsidiaries, these discussions do not equate to a contractual obligation. The projects are rooted in an intergovernmental cooperation agreement signed by Montenegro and Hungary in July 2025, which focuses on infrastructure development, telecommunications, and information technology.
The proposed data centre is intended to bolster Montenegro’s state-controlled digital infrastructure as the nation invests in public sector digitalization, cybersecurity, and data management capabilities. In August, 4iG announced plans to establish a dedicated energy division and explore investment opportunities throughout the region. In North Macedonia, the company is looking into wind and energy storage projects exceeding 100 MW, alongside a proposal related to a wind portfolio in Hungary.
Additionally, 4iG has entered into a non-binding agreement with U.S.-based X-energy to investigate the implementation of small modular nuclear reactor technology within Central and Eastern Europe and the Western Balkans. For the first half of 2026, 4iG reported consolidated revenues of 409.4 billion forints, marking a 16.7% increase compared to the previous year. The company achieved a profit after tax of 21.9 billion forints, recovering from a loss reported during the same period in 2025, with telecommunications remaining its primary business segment.
The forthcoming phase for 4iG in Montenegro will depend on whether negotiations yield binding contracts and an established financing framework for the state data centre. Details regarding the scale and timeline of any further investments by 4iG in Montenegro’s energy sector are still undetermined.
