Chinese capital, OEMs and project takeovers are increasingly being discussed as a way to accelerate renewable deployment in Southeast Europe, alongside equipment supply. The investment model described for the region includes equity acquisitions, EPC delivery, OEM-backed development, battery storage integration and strategic project takeovers. The approach is framed as potentially helpful for SEE markets where European lenders are becoming more selective about merchant risk, curtailment and grid delays.
Serbia deal highlights shift toward project ownership
The clearest recent example cited is Serbia. In June 2026, China’s Heavy Energy International, a Hong Kong-based subsidiary of Sany Renewable Energy, acquired the 168 MW Alibunar wind project in Serbia. The transaction is described as more bankable than speculative pipeline assets because the project had already passed through Serbia’s auction system for market premiums.
The deal is presented as an indicator of where the market is moving. Chinese players are no longer limited to selling turbines, modules, inverters or batteries into SEE. They are beginning to buy projects, influence equipment selection, integrate EPC delivery and potentially capture long-term operating upside.
Potential market effects from OEM-backed capital
One stated benefit is CAPEX pressure reduction from Chinese OEM supply chains. The text links this to solar, batteries and increasingly wind manufacturing dominance by Chinese firms. It also notes that many SEE projects can become financially marginal once grid connection costs, balancing exposure, land acquisition, permitting delays and higher interest rates are included.
A second effect described is faster movement from development to construction through OEM-backed equity. A local developer may hold land, permits and grid applications but lack balance-sheet capacity for procurement deposits, construction guarantees or delay risk. In this model, a Chinese OEM or EPC investor can combine equipment supply, engineering capacity and project equity in a single package.
A third effect involves creating liquidity for stranded or delayed projects. Serbia’s grid-access tightening is cited as making this more relevant. Projects with incomplete documentation or uncertain connection timing may struggle, while those with advanced grid status, auction premiums or near-ready permits could become acquisition targets.
BESS growth and hybrid buildout in regional portfolios
The text also points to battery storage as a driver of the next renewables cycle in SEE. It cites SolarPower Europe estimates that the EU installed 27.1 GWh of new battery storage in 2025, bringing operational BESS capacity to 77.3 GWh. It further states that CATL expects energy storage to account for 50% of global sales by 2030, up from around 25% today.
Batteries are described as addressing structural risks for solar projects exposed to midday price effects, curtailment and imbalance charges. The text says batteries convert part of that risk into tradable flexibility by shifting output into evening peaks and reducing negative-price exposure. It also notes potential for ancillary services and grid stability support in markets where TSOs are becoming more cautious.
Hybrid structures are another area highlighted for Chinese EPC and OEM groups. The most bankable projects in 2026–2028 are described as increasingly involving solar-plus-storage, wind-plus-storage or solar-wind-BESS portfolios. The integrated supply chain referenced includes PV modules, battery cells, inverters, EMS software, transformers, EPC construction and long-term service agreements.
Partnership examples and regional execution capacity
The text cites partnerships such as Fortis Energy and PowerChina. Their cooperation is said to be framed around wind and solar project development and construction in Serbia and the wider region. This is presented as linking Chinese EPC capability with local and regional project origination.
Similar models are described as possible across Romania, Bulgaria, North Macedonia, Bosnia and Herzegovina and Montenegro. The rationale given is that local developers often need a strategic construction partner before projects become financeable.
Four areas cited for market-development upside
The first area identified is project rescue for assets that are technically promising but financially stuck. Examples given include projects with land and permits but no bankable EPC, projects with grid progress but no equity, and projects with offtake interest but no storage strategy. Chinese equity or OEM-backed offers are described as a route out of development limbo.
The second area is CAPEX compression through lower equipment pricing that can improve DSCR and reduce tariff pressure in auctions while helping projects withstand higher financing costs. This is said to be particularly important in Serbia and Montenegro due to economics exposed to grid delays, balancing requirements and smaller market liquidity.
The third area concerns industrial supply-chain formation if Chinese OEMs localise assembly components such as service operations, warehousing, training or maintenance in SEE. For banks, the text links localisation to improved O&M comfort via closer spare parts access and warranty response.
The fourth area is storage-led market modernization with Bulgaria and Romania described as reference markets for BESS. Bulgaria’s approvals are cited: subsidies for 82 standalone battery storage projects, representing about 9.71 GWh of capacity and €587 million in support.
Grid integration constraints and compliance risks
The text identifies risks alongside the potential benefits. The largest risk described is that Chinese-backed projects may reduce CAPEX without resolving grid integration needs such as connection ability, dispatch capability, imbalance management and curtailment resilience. In Serbia specifically, it cites EMS’s decision to slow connection procedures for large renewables until 2029 as showing that system flexibility can be the bottleneck rather than capital alone.
A second risk highlighted is regulatory scrutiny tied to cybersecurity concerns in EU-funded solar inverter deployments. It states that EU actions have targeted Chinese-made solar inverters used under public funding schemes citing cybersecurity issues. It also notes that Huawei and Sungrow have held major shares of the European market but that new restrictions could affect procurement for subsidised or EU-linked schemes.
A third risk relates to bankability under European lender standards. Lenders are said to require clarity on governing law, parent-company guarantees, dispute resolution mechanisms, spare-parts availability and battery degradation curves alongside grid-code compliance. The text also lists SCADA cybersecurity requirements and long-term service obligations as elements expected by serious project finance lenders.
A fourth risk concerns political optics around ownership transfer of strategic energy assets without transparent procurement processes or system-security safeguards. The sensitivity described includes transmission-connected BESS assets, grid-forming inverters linked to SCADA systems, and large wind or solar parks receiving market-premium support.
Country-specific considerations mentioned: Montenegro; Romania; Bulgaria
The practical guidance provided is that Chinese offers should be structured as development accelerators rather than only sale exits. The model described involves local developers contributing land, permits, grid knowledge and stakeholder management while Chinese partners contribute equipment supply capability, EPC strength, equity participation and delivery capacity under documentation acceptable to European lenders, TSOs and offtakers.
For Serbia specifically, the text says the market needs fewer speculative megawatts and more executable projects where EMS connection risk, balancing obligations and auction premium exposure are properly modelled. It reiterates that the Alibunar transaction suggests targeting of projects with stronger bankability profiles rather than early-stage greenfield pipelines.
For Montenegro, it states Chinese participation would need to compete with or complement utility-backed and Gulf-backed structures such as the EPCG–Masdar renewables platform. Because Montenegro’s system is smaller per the text’s framing, it says Chinese capital would be most useful in storage deployment such as solar-plus-BESS configurations plus grid-support services and EPC delivery rather than uncontrolled merchant solar buildout.
The text adds that a Chinese battery or EPC partnership with EPCG or private developers could strengthen energy security if linked to hydro balancing, cross-border exports and industrial offtake arrangements. For Romania and Bulgaria it says Chinese OEMs and storage providers can play a major role but must navigate stricter procurement rules along with cybersecurity requirements tied to subsidy schemes.
Lender selectivity context for Southeast Europe financing
The broader benefit described for SEE is increased liquidity in renewables markets through additional buyer classes for developers alongside alternative financing channels for governments. It also says this can increase execution capacity within EPC markets while lowering-cost supply bases support storage deployment scaling across the region.
The text also states that European suppliers, banks and utilities may face pressure to respond by becoming faster or more competitive amid increased competition from Chinese capital models.
