The European Commission’s recent endorsement of power purchase agreements (PPAs) as a central element in the energy investment framework marks a pivotal change for South-East Europe’s electricity markets. Adopted on 22 April 2026, this recommendation emphasizes a shift away from reliance on state guarantees towards structured, long-term contracts between energy producers and industrial consumers. This new approach is set to redefine the investment landscape for renewable energy, storage solutions, and industrial decarbonization in Serbia, Montenegro, and the broader Energy Community over the coming years.
At the heart of this recommendation is the recognition that PPAs are essential for achieving the EU’s ambitious targets of 42.5% renewable energy and a minimum 55% reduction in emissions by 2030. This policy shift positions South-East Europe not merely as a peripheral player but as an integral supply-side component of the EU’s clean energy framework, particularly through cross-border contracting mechanisms.
The growth trajectory within Europe reflects this transition, with corporate PPAs increasing from 7.4 TWh in 2020 to an anticipated 31.4 TWh by 2024. The number of agreements has surged from 60 to 276 during this period, with solar photovoltaic technologies now surpassing wind as the leading source of contracted capacity. The emergence of hybrid contracts that incorporate storage solutions signals a significant evolution in how energy risk is managed and priced.
For South-East Europe, the Commission’s support for cross-border PPAs is particularly consequential. These agreements facilitate electricity trading across national borders, thereby integrating regional markets into the EU’s internal electricity framework while simultaneously driving investment in new generation capacities. Serbia and Montenegro find themselves at a critical juncture, balancing rising EU demand for clean energy with regional price disparities that favor export-oriented generation.
However, significant regulatory hurdles remain that could impede market scalability. Issues such as grid access limitations, slow permitting processes, and inconsistencies in accounting practices pose challenges to project development. In Serbia, for instance, delays in expanding transmission capacity at the 400 kV level directly affect the financial closure of renewable projects. Similarly, Montenegro faces constraints related to its system size and interconnection capabilities that hinder monetization of excess generation through long-term contracts.
Non-regulatory barriers also present substantial challenges. The Commission highlights issues such as buyer creditworthiness, transparency deficits, and limited standardization of contracts as persistent obstacles. These factors are particularly pronounced in South-East Europe, where fewer large industrial consumers exist compared to Western Europe, making it difficult for project developers to secure financing despite favorable resource conditions.
In response to these challenges, the EU is advocating for a multi-layered risk mitigation strategy. Member States are encouraged to implement state-backed guarantee schemes aligned with the European Investment Bank’s counter-guarantee program set for 2025. For Serbia, where demand from sectors like metals and chemicals is unevenly distributed but growing, these mechanisms could unlock substantial PPA opportunities. Conversely, Montenegro may rely more on export-linked contracts supported by international buyers due to its smaller industrial base.
The evolving nature of PPAs illustrates a more nuanced risk allocation framework. The Commission differentiates between physical and financial contracts as well as various delivery profiles that impact exposure to price volatility and balancing costs—key factors influencing project bankability and equity returns. In Serbia’s developing market context, there is already a noticeable shift from traditional pay-as-produced contracts towards more sophisticated hybrid arrangements.
This transformation occurs against a backdrop of increasing renewable generation leading to price cannibalization and more frequent negative pricing hours—issues that complicate PPA negotiations and erode developer revenues. Such dynamics are beginning to manifest in parts of South-East Europe during periods characterized by high solar output coupled with limited export capabilities. Future projects will likely necessitate integrated approaches combining generation with storage or demand response strategies to stabilize revenue streams.
The interaction between PPAs and state support mechanisms is thus critical. The Commission acknowledges that two-way Contracts for Difference (2w-CfDs) can provide revenue stability but warns they may inadvertently undermine private PPA markets if not well-designed. The preferred strategy involves coexistence: allowing portions of project outputs to be contracted via PPAs while also utilizing state-backed supports where necessary. This blended approach offers a viable path for scaling investments amidst constrained public budgets in South-East Europe.
Additionally, the expansion of multi-buyer PPAs—where multiple smaller consumers consolidate demand—could enhance project viability in fragmented markets like Serbia’s. By aggregating demand through industrial parks or business associations, these models can create bankable structures unattainable by individual companies alone. Montenegro could similarly benefit from such arrangements to support export-oriented initiatives involving both domestic and foreign buyers.
The establishment of market platforms for PPA trading represents another significant advancement towards formalizing these agreements into more liquid market instruments. By enhancing transparency and reducing transaction costs, such platforms could facilitate greater integration of local projects into broader European energy portfolios—a critical step given South-East Europe’s current market limitations.
Moreover, reforms surrounding guarantees of origin—certificates verifying renewable electricity—are vital as they evolve towards time granularity aligned with market intervals and full cross-border transferability. This change will enhance the value proposition of renewable energy based on its temporal and geographical attributes while emphasizing the need for flexibility solutions in project design across Serbia and Montenegro.
The recommendation also extends long-term contracting frameworks beyond electricity to include hydrogen, biomethane, heating, and cooling agreements—signifying an evolving landscape where integrated energy projects can thrive as decarbonization efforts accelerate across industries.
Collectively, these developments indicate a significant reconfiguration of the energy investment paradigm in South-East Europe. The traditional model reliant on state-driven capacity expansion is yielding to one where long-term contracts among private entities play a crucial role in financing and risk management. As states transition from primary buyers or guarantors to facilitators of market conditions, targeted support will increasingly focus on enabling contractual mechanisms that effectively allocate risk.
This transition presents both opportunities and challenges for South-East Europe’s energy sector. With abundant resources in solar and wind potential positioning the region as a prospective clean electricity exporter to the EU, addressing structural constraints related to grid infrastructure and regulatory alignment will be essential for realizing this potential fully. While the Commission’s recommendations do not resolve these issues outright, they provide a strategic framework for navigating them effectively.
In conclusion, the anticipated acceleration of project development pipelines linked to cross-border PPAs is particularly evident in Serbia due to favorable industrial demand dynamics and grid connectivity prospects. In contrast, Montenegro may focus on export-oriented projects leveraging its geographical advantages within the Adriatic region. Success in both scenarios hinges on aligning national regulatory frameworks with evolving EU standards across key areas such as guarantees of origin and permitting processes.
