The European PPA market is changing. The simple 10-year, pay-as-produced solar PPA still has its place. Many buyers continue to sign these agreements, often as financial PPAs, because they want a long-term price reference and a credible renewable claim, and are comfortable managing the shape themselves. But for a growing share of the market, that product alone is no longer enough.

As solar penetration has increased, so has cannibalisation. Renewable generation is increasingly concentrated in the same hours, while many buyers need power regardless of when the sun shines. For these customers, a solar-only contract covers only part of their real exposure and leaves them buying the rest on the spot market, including when prices peak.

Hybrid PPAs, combining solar with wind or storage, can help meet that need. They deliver a profile closer to actual consumption and a more predictable cost, which makes the business case easier to build internally. For developers, they open the door to buyers who would never sign a pure solar deal, while preserving more of the value of each megawatt-hour produced. Together, pay-as-produced and hybrid structures let us serve a much wider range of customers.

From generation to profile

Europe contracted more than 700 MW of hybrid PPAs in 2025, with much of that activity coming in the second half of the year. In the first half of 2026 alone, around 1.1 GW of hybrid deals were announced, across solar-plus-storage and other multi-technology combinations. These figures cover more than just solar and batteries, but show growing demand for a better generation profile.

A battery can shift solar production away from low or negative price hours into periods when electricity is more valuable. It can also allow a developer to offer an offtaker something closer to the profile it actually needs.

We see solar-plus-BESS PPAs commanding premiums of around €10–15 ($11.12 to $16.69)/MWh in some markets and structures, equivalent to roughly 18–25% depending on the underlying PPA price. In Germany, specialist market analysis suggests that adding storage to a solar project can increase its capture factor from around 50 per cent to over 80 per cent of the average wholesale electricity price, depending on battery sizing, market conditions and operational constraints.

But the premium also pays for a transfer of risk. Under a hybrid PPA, the seller or optimiser can take on responsibility for shaping the generation profile, alongside the risks associated with battery degradation, efficiency, operational management and replacement capacity.

That complexity is currently one of the biggest challenges to further growth. There is no established rulebook for pricing hybrid PPAs. Every project can have a different combination of solar resource, storage duration, grid constraints, optimisation strategy, market prices and offtaker requirements. Buyers are also being asked to understand contracts that are considerably more sophisticated than traditional pay-as-produced arrangements.

The next PPAs will be more flexible

The market needs structures that capture the value of flexibility, but are simple enough for an offtaker to understand and commit to over 10 or 15 years. Developing these will take time, particularly while there is still limited historical experience of how these contracts perform through different market conditions.

Grid infrastructure is another constraint. A battery needs sufficient import and export capacity to operate as modelled. A shared connection can accelerate project development, but may limit the battery’s ability to operate independently. These limits directly affect the economics of the hybrid.

I expect utilities and traders to become increasingly important. They can aggregate solar, wind and storage across portfolios and use diversification to manage profiling and balancing risks that individual corporate buyers may be unwilling to take. The rise of hybrid PPAs could therefore accelerate a broader shift away from purely bilateral developer-to-corporate contracts.

The standalone PPA will not disappear. But for buyers seeking a closer match to their consumption, one renewable asset under a fixed-price, a pay-as-produced contract may not provide an adequate long-term hedge.

Solar and storage will increasingly be contracted together. Wind and solar will be combined, and utilities and traders will become more important partners for developers, as buyers seek to manage the complexity of these structures.

In a renewables-heavy electricity system, when power is produced can be almost as important as how much is produced.
