Buyer due diligence shifts from capacity to risk factors
Renewable-energy valuations in South East Europe are increasingly shaped by questions beyond installed capacity, resource quality and tariff support. Buyers are now assessing whether projects are grid-secured and whether revenue is contracted. They also evaluate curtailment risk, the possibility of adding storage, and whether assets face merchant exposure, alongside the maturity of local balancing markets.
The change has contributed to a wide valuation spread between speculative development projects and operating platforms. Recent transactions have been used as benchmarks for how operating assets and larger platforms clear in the region.
Greece wind and solar portfolio benchmarks
TotalEnergies sold 50% of a 424 MW operating wind and solar portfolio in Greece. The transaction valued the full portfolio at €508 million, equivalent to about €1.2 million per installed MW. TotalEnergies retained 50% and continued to operate the assets.
EDPR’s sale of a 150 MW operating wind portfolio in Greece to Principia provides another reference point. The portfolio included four operating wind farms with an average asset life of about 1.5 years and 20-year Contracts for Difference. The reported enterprise value was around €200 million, implying roughly €1.3 million per MW.
Romania operating renewables and pipeline acquisition
PPC’s Evryo acquisition in Romania adds a larger operating-portfolio comparison. PPC acquired 629 MW of operating renewables, mainly onshore wind, plus about 145 MW of pipeline assets. The transaction had an enterprise value of approximately €700 million.
The deal was expected to add about €100 million of annual EBITDA. Together with the Greece examples, the transactions indicate that operating contracted wind and solar portfolios in stronger SEE markets can clear around €1.1 million to €1.3 million per MW, depending on technology, revenue structure, asset age, market conditions, financing and operating risk.
Platform valuations differ from pure MW comparisons
The range is not applied mechanically when transactions involve broader platforms rather than standalone assets. Masdar’s TERNA Energy transaction illustrates the difference between asset-level pricing and platform-level pricing. TERNA Energy had around 1.2 GW of operating capacity, but the enterprise value was around €3.2 billion.
A simple operating MW basis would imply a higher valuation than asset-level comparables, but the buyer was described as paying for a strategic platform, development pipeline, market position, management team and pumped-hydro optionality . The distinction between asset transactions and platform transactions is therefore treated as a separate market.
Solar frameworks across multiple countries
For solar, valuation is described as becoming more complex due to deal structures that may cover development rather than only operations. A PPC–Metlen framework agreement covers up to 2 GW of solar projects across Italy, Romania, Bulgaria and Croatia. The transaction value was estimated at up to €2 billion.
This implies around €1 million per MW, but the structure is characterized as a development-and-construction framework rather than a clean operating-asset sale . As a result, buyers’ pricing reflects different risk profiles across project stages.
CfDs, feed-in tariffs and corporate PPAs influence financing confidence
The valuation focus is described as shifting from capacity alone toward de-risking factors such as grid connection, land rights, permits, bankable EPC terms, predictable offtake, low curtailment risk and credible construction schedules. Projects with only early-stage permits or unclear grid access are described as worth less when compared with those that have progressed further.
Revenue structure is identified as especially important for valuation outcomes. Projects backed by CfDs, feed-in tariffs or strong corporate PPAs typically command better financing terms and higher valuation confidence.
A Romania CfD scheme has awarded 4.2 GW of solar and wind capacity across two auctions under the country’s Recovery and Resilience Plan context. This total exceeds Romania’s stated target of 3.5 GW.
Merchant exposure and storage optionality in underwriting
Merchant exposure is described as more nuanced than simply negative for all technologies. In high-volatility markets, merchant projects can capture upside, while standalone solar exposed to midday prices faces capture-price pressure as solar penetration rises.
A merchant solar asset without storage or flexible offtake is described as not carrying the same risk profile as a merchant wind asset or a hybrid asset . Storage optionality is also highlighted as a potential differentiator for future valuations.
Bulgaria battery subsidies signal growing storage integration
Bulgaria’s approval of subsidies for 82 standalone battery projects totaling 9.71 GWh is cited as evidence that storage is becoming part of the regional investment map . A solar site with spare grid capacity for batteries may trade at a premium compared with an otherwise similar site without that option.
The practical valuation map described for SEE places operating contracted wind and solar portfolios at the top of the asset-value range. Strategic platforms can trade above simple MW multiples, while ready-to-build projects depend on grid and permits being real; early-stage pipelines are discounted; merchant-only solar becomes harder to underwrite unless storage, offtake or trading strategy is credible.
The shorthand presented is that MWs are treated as cheap when they are theoretical and expensive when they are deliverable in South East Europe.
