CBAM, PPAs and the new bankability model for wind, solar and battery storage

[[PRRS_LINK_1]] is quietly transforming the financing logic of [[PRRS_LINK_2]] across Europe and especially throughout South East Europe. Until recently, wind, solar and battery-storage projects were financed mainly through a combination of merchant-price assumptions, feed-in support schemes, balancing economics and traditional utility offtake structures. From 2026 onward, another layer becomes increasingly important: the ability of renewable electricity to function as a carbon-risk reduction instrument for industrial buyers exposed to CBAM.

This changes the role of PPAs fundamentally.

A power purchase agreement is no longer only a revenue hedge between a renewable generator and an electricity consumer. Under CBAM conditions, the PPA increasingly becomes part of an industrial exporter’s carbon strategy, financing strategy and long-term competitiveness model.

For banks, this creates a major shift in renewable project bankability.

CBAM turns renewable electricity into industrial compliance infrastructure

Industrial exporters across Europe increasingly face pressure to demonstrate lower embedded emissions in products entering the EU market. For steel, aluminum, fertilizers, chemicals, cement and energy-intensive manufacturing, electricity sourcing now directly influences carbon exposure.

As a result, renewable electricity gains a second value layer beyond the visible wholesale price.

The first layer remains the energy value itself — the €/MWh received from the market or contracted through a PPA.

The second layer is the carbon-adjusted industrial value attached to verifiable low-carbon electricity.

This second layer is becoming increasingly important for exporters trying to reduce CBAM exposure.

Banks understand this dynamic.

A renewable project supplying electricity to an industrial exporter under a long-term structured PPA may therefore become materially more bankable than a standalone merchant project exposed entirely to wholesale volatility.

The reason is that the renewable asset is no longer only selling electricity. It is helping preserve industrial export competitiveness.

Why PPAs are becoming more valuable to banks

Historically, banks evaluated PPAs primarily through:

• Counterparty strength
• Contract tenor
• Price stability
• Curtailment exposure
• Balancing risk
• Grid connection reliability
• Settlement structures

Those variables remain critical, but CBAM introduces additional considerations.

Banks increasingly ask:

• Does the PPA help reduce industrial carbon exposure?
• Can the electricity sourcing withstand verification scrutiny?
• Is the supply physically credible?
• Can emissions reductions be documented?
• Does the industrial buyer remain competitive under CBAM?

This changes lender perception of renewable assets.

A wind or solar project linked to a strong industrial exporter with CBAM-sensitive operations may achieve superior financing conditions because the offtake relationship becomes strategically important for both sides.

Physical PPAs become more important than pure financial structures

CBAM also strengthens the importance of physically connected electricity structures.

European regulators and industrial buyers increasingly focus on:

• Traceable electricity sourcing
• Metering systems
• Physical delivery logic
• Hourly or granular matching
• Grid connection evidence
• Auditable emissions calculations

This means purely synthetic green claims may become less valuable than physically demonstrable renewable supply arrangements.

For SEE markets, this is especially important because the region remains heavily interconnected with coal-based electricity systems.

Industrial exporters in Serbia, Montenegro, Bosnia and neighboring markets increasingly require evidence that renewable electricity is genuinely linked to operations rather than simply purchased through detached certificates.

This favors renewable projects capable of integrating:

• Dedicated industrial offtake
• Private-wire structures
• Industrial parks
• Direct balancing arrangements
• Battery-supported delivery stability

Battery storage changes renewable bankability under CBAM

Battery storage becomes critically important in this environment because CBAM increases the value of operational flexibility.

The old merchant renewable model relied heavily on high capture prices and stable spread economics.

However, from 2026 onward, SEE electricity markets increasingly face:

• Negative prices
• Solar cannibalization
• Volatility spikes
• Congestion
• Cross-border flow instability
• Carbon-adjusted export pressure

This is already visible through SEEPEX negative-price implementation beginning in May 2026.

In that environment, BESS becomes more than an arbitrage tool.

Storage helps renewable assets provide:

• Stable industrial delivery
• Peak-hour optimization
• Carbon-efficient balancing
• Curtailment reduction
• Intraday flexibility
• Grid-support services
• Improved renewable capture pricing

For banks, hybrid wind-solar-BESS projects increasingly appear structurally stronger than standalone intermittent generation because they improve operational predictability.

CBAM quietly favors hybrid renewable structures

The market is therefore moving toward hybrid structures where:

• Wind provides higher capacity-factor stability
• Solar provides low daytime marginal cost
• Battery storage manages volatility and delivery quality
• PPAs anchor industrial revenues

This combination increasingly aligns with what lenders seek:

• Long-term contracted cash flow
• Reduced merchant exposure
• Industrial strategic relevance
• Carbon-transition alignment
• Lower curtailment risk
• Improved DSCR stability

In SEE, this trend could become especially powerful because industrial exporters simultaneously need:

• Lower-carbon electricity
• Stable long-term pricing
• Protection from EU carbon costs
• Reliable physical delivery

Banks financing such projects may therefore view CBAM-linked industrial PPAs as quasi-infrastructure relationships rather than simple commercial power contracts.

Wind gains strategic importance in SEE

CBAM may particularly strengthen the strategic position of wind projects across Serbia, Montenegro and the wider Balkans.

Wind offers several advantages in this environment:

• Higher annual capacity factors
• Better winter production correlation
• Reduced daytime solar cannibalization
• Lower seasonal volatility
• Stronger nighttime delivery capability
• Better alignment with industrial baseload demand

When integrated with BESS and industrial PPAs, wind projects may become highly attractive financing candidates for banks seeking resilient low-carbon infrastructure exposure.

Projects such as large-scale Serbian and Montenegrin wind developments therefore increasingly sit at the intersection of:

• Energy transition
• Industrial competitiveness
• CBAM mitigation
• Export resilience
• Grid modernization

CBAM creates a new renewable revenue layer

Perhaps the most important market shift is that renewable electricity increasingly carries hidden strategic value.

The market no longer prices only electricity generation.

It increasingly prices:

• Carbon competitiveness
• Industrial decarbonisation capability
• Verification readiness
• Export resilience
• Supply-chain positioning

A renewable project supporting a CBAM-sensitive industrial exporter may therefore possess stronger long-term economics than merchant pricing alone suggests.

Banks are beginning to recognize this.

The next financing cycle in SEE will likely be CBAM-driven

For South East Europe, this may become one of the largest infrastructure financing trends of the decade.

The region simultaneously faces:

• Coal-heavy electricity systems
• Growing renewable buildout
• EU integration pressure
• Industrial export dependence
• Grid congestion
• Negative price emergence
• Need for storage
• CBAM-adjusted trade exposure

That combination naturally pushes capital toward:

• Wind
• Solar
• Battery storage
• Industrial PPAs
• Grid reinforcement
• Flexible balancing systems

The result is that renewable projects are no longer financed only because they are green.

Increasingly, they are financed because they help preserve industrial competitiveness inside Europe’s carbon-adjusted economic system.
