By 2025, corporate power purchase agreements in Southeast Europe moved decisively out of pilot territory and into the core commercial architecture of the regional electricity market. What began as a niche instrument used by multinationals with global decarbonisation mandates has evolved into a practical procurement tool for a much broader segment of industrial and commercial electricity consumers. At the same time, PPAs have become one of the most important stabilisation mechanisms for renewable electricity producers navigating rising merchant exposure, price volatility and solar cannibalisation.
The underlying driver is structural rather than ideological. Electricity prices in SEE remain volatile, shaped by gas marginal pricing, hydrology, cross-border congestion and rapidly increasing renewable penetration. For industrial consumers, particularly those with 10–50 GWh per year electricity demand, this volatility has translated into budgeting uncertainty and margin risk. For renewable producers, merchant exposure increasingly undermines bankability and asset valuation. Corporate PPAs sit precisely at the intersection of these pressures, converting volatility into contractable risk.
In 2025, the SEE corporate PPA market matured along three dimensions simultaneously: buyer diversity, contract sophistication and geographic scope. Early PPAs were dominated by international technology firms, data centres and FMCG groups sourcing power in Romania and Greece. By 2025, buyers expanded to include regional metals processors, automotive suppliers, chemicals, food processors and logistics operators, many of whom had no formal net-zero obligations but faced material electricity cost exposure.
Contract sizes followed this shift. While large multinationals continued to sign 100–300 GWh multi-asset PPAs, the fastest growth occurred in mid-sized contracts of 20–80 GWh per year. These volumes align closely with the output of single wind farms or aggregated solar portfolios, making them structurally attractive to renewable producers seeking revenue certainty without fully surrendering upside.
Pricing dynamics reveal why PPAs gained traction. In 2025, structured corporate PPAs in SEE typically cleared in a band of €75–90 per MWh, depending on duration, shaping and credit support. This pricing sat below long-term expectations for wholesale electricity inflation, while remaining above marginal renewable production costs by a wide margin. For producers with wind or solar operating costs below €20 per MWh, these contracts locked in strong EBITDA visibility. For buyers, PPAs offered long-term price certainty at levels competitive with forward market hedging, but without rolling basis risk.
Shaping emerged as the critical differentiator. Flat baseload PPAs were increasingly rare. Buyers demanded profiles that matched operational consumption patterns, particularly for industrial loads concentrated during daytime or early evening hours. Renewable producers responded by aggregating multiple assets or layering storage and hydro flexibility into PPA delivery. In 2025, shaped PPAs commanded €8–15 per MWh premiums over unshaped renewable offtake, reflecting the real system cost of matching generation to demand.
Romania stood out as the most liquid SEE PPA market. Strong wind penetration, robust interconnections and relative regulatory clarity supported a wide range of structures. Wind-dominated PPAs in Romania commonly ran for 10–12 years, with price indexation partially linked to inflation. Solar-heavy PPAs increasingly required shaping or storage integration to remain competitive. The result was a rapid convergence between PPA structuring and portfolio aggregation, blurring the line between offtake contracting and active power management.
Greece followed closely, though with greater regulatory complexity. Support schemes exposed renewable producers to spot prices while offering downside protection, making PPAs an optimisation tool rather than a necessity for all assets. Nevertheless, corporate demand expanded rapidly in 2025, particularly from export-oriented manufacturers seeking to stabilise energy costs ahead of EU carbon exposure. PPA prices in Greece tended toward the upper end of the regional range, reflecting higher system volatility and shaping costs.
Bulgaria presented a contrasting case. Rapid solar expansion created deep midday price compression, making PPAs essential for solar asset bankability. Corporate buyers were cautious, however, due to regulatory uncertainty and evolving grid rules. Where deals closed, they often included price floors and volume adjustment mechanisms, transferring part of the variability risk back to producers or aggregators. Even so, PPAs provided a clear improvement over fully merchant exposure.
Serbia entered the corporate PPA market more cautiously but with clean fundamentals. Wholesale power prices remained elevated relative to production costs, and industrial consumers faced rising exposure to carbon-related cost pressures. In 2025, early Serbian PPAs focused on wind and mixed wind-solar portfolios, often structured with cross-border delivery components. Effective prices frequently exceeded €85 per MWh, reflecting scarcity of domestic renewable capacity and strong demand for long-term price certainty.
Credit risk management became a defining feature of the PPA market. Unlike state-backed offtake, corporate PPAs require careful assessment of counterparty strength. In SEE, this risk was mitigated through parent guarantees, escrow structures, and increasingly through aggregation platforms acting as intermediaries. These platforms assumed buyer credit exposure while offering producers investment-grade risk profiles. In return, they captured margins of €2–5 per MWh, reinforcing PPAs as a service-driven business rather than a pure bilateral contract.
From a financing perspective, PPAs materially altered project economics. Assets backed by long-term corporate PPAs secured lower cost of debt, improved debt service coverage ratios and higher equity valuations. In 2025, transaction evidence suggested that PPA-backed renewable assets traded at 0.5–1.5 EBITDA multiple premiums compared with merchant-exposed peers. This valuation uplift alone justified the commercial effort required to structure and negotiate complex contracts.
For buyers, PPAs delivered benefits beyond price. They provided traceable renewable supply, hedged regulatory risk and, in some cases, enabled preferential grid access or industrial co-location strategies. For energy-intensive exporters, PPAs increasingly functioned as part of broader competitiveness strategies rather than standalone energy procurement decisions.
The strategic importance of corporate PPAs in Southeast Europe lies in their scalability. Unlike feed-in tariffs or premiums, PPAs do not depend on state budgets or political cycles. They scale with industrial demand, capital availability and market sophistication. By 2025, they had become the primary bridge between renewable generation growth and industrial power consumption in the region.
As renewable penetration deepens and merchant exposure grows, corporate PPAs are likely to move further upstream in project development. Increasingly, new wind and solar projects in SEE are being designed with anchor PPAs in place before financial close. This represents a structural shift. Renewable electricity in Southeast Europe is no longer sold first to the market and then hedged. It is increasingly contracted at source, with risk allocated deliberately between producers, intermediaries and consumers.
