Since 2019, Pexapark has published daily price assessments for wind and solar PPAs. These price assessments are based on Pexapark’s quantitative pricing model and supported by market price evidence – bids from qualified market participants. These assessments give a consistent benchmark for the intrinsic worth of a specific PPA structure is fundamentally worth – its fair value.

The price actually paid in the market, however, may diverge from the fair value. Developers typically price based on cost rather than value. Utilities may be more conservative in their assessment of risk than the broader market. And corporate offtakers are often willing to pay a premium above the fair value to meet sustainability targets. As renewables increasingly diverge from baseload power, market participants are taking different approaches to pricing PPAs.

To provide greater transparency into these market dynamics, Pexapark has introduced a Transactable Price Range, where feasible, to show both a contract’s fair value and the price where it is most likely to transact.

The Transactable Price Range shows the price levels at which a PPA can realistically transact today, based on observed market price data and monthly price polling. It displays the overlap between bids and offers, providing visibility into both the buy and sell side of the market and highlighting the zone where deals can realistically close.

Each Transactable Price Range is provided by country, technology, and contract structure (e.g., baseload or. pay-as-produced) in markets where sufficient verified market evidence exists to support a transparent and credible price range.

Within the Transactable Price Range, an assessed Transactable Price is shown. This is Pexapark’s best assessment of the specific price level where transactions are most likely to close.

A price is considered transactable if it falls within the level where credible buyers (offtakers) and sellers are actively willing to trade, supported by real market evidence. It is not a theoretical valuation, but a reflection of actual market interest.

Pexapark’s Fair Value estimates the intrinsic worth of a PPA, showing the risk-adjusted contract value. These values are calculated using forward curves, renewable-specific risk discounts, as well as systematically gathered market prices from utility buyers. Fair value estimates provide a daily, unbiased benchmark for the energy-only value for contract valuation, accounting, and financial reporting.

Pexapark’s PPA Fair Values exclude premia, such as the additionality premium often paid by corporates for PPAs from additional, new-build clean energy prices and other market dynamics.

A Transactable Price Range, by contrast, shows the actual price levels where buyers and sellers align in today’s market. They are entirely market-based, derived from bids and offers collected from credible buyers and sellers through monthly IOSCO-aligned PPA price polls, alongside data from live PPA negotiations and concluded transactions.

No. Each range shows the current overlap between credible buyer bids and seller offers, providing transparency into both sides of the negotiation.

Pexapark voluntarily aligns with the International Organization of Securities Commissions (IOSCO) principles, which require benchmarks to reflect the full market by incorporating data from a broad and representative set of participants. This means our transactable price assessments are based on a wide range of credible inputs - including bids, offers, and transactions - to ensure an unbiased view of prevailing market conditions.

By following IOSCO principles, Pexapark’s PPA price polls capture genuine buy- and sell-side interest across the market, rather than reflecting the perspective of a few individual actors.

Each Transactable Price Range is updated monthly with new price observations, including verified transaction evidence and results from Pexapark’s polling process.

In addition to the latest update, the Pexapark platform also shows historic Transactable Prices and Ranges in both graph and table format, allowing you to track how pricing evolves month by month.

Together, these three data sets provide the complete picture: what a contract is intrinsically worth, where buyers and sellers overlap on price, and where a deal could reasonably close today.

To ensure transparency and credibility, a Transactable Price Assessment and Range is only published where sufficient verified market evidence exists. At launch, this means six markets: France, Germany, Great Britain, Italy, Poland, and Spain.

Our methodology involves validating and aggregating active market signals—such as bids, offers, negotiations, and executed transactions. We assess these signals for credibility, normalize them for deal structure, and verify them by market expert oversight to ensure consistency.

Pexapark uses market-observed PPA price data from a number of sources:

It is primarily driven by current market pricing dynamics— bids, offers, and live negotiations. We also consider recently executed deals, but the focus is on present-day transactable levels rather than historical prices.

Pexapark’s Editorial Team rigorously verifies all collected price information. We cross-check data using multiple sources to ensure accuracy and representativeness. This multi-source verification process helps eliminate errors, biases, and outdated inputs.

When an overlap is shown, it indicates that buyer and seller price expectations align, and transactions are likely within this range. The lower bound reflects Pexapark’s assessment of the lowest price where buyers and sellers are overlapping, while the upper bound reflects the highest level at which buyers are still likely to engage.

The width of the range also provides important insight into transaction feasibility. A narrow range means there is limited room for price negotiation and fewer opportunities to close a deal. A wider range, on the other hand, suggests stronger market interest, more flexibility in negotiations, and a higher likelihood of transactions being concluded.

Together, these bounds and the width of the range define the market zone where deals are most likely to close under current conditions.

When there is no overlap between buyer bids and seller offers, it signals that market pricing expectations are misaligned and transactions are unlikely to occur unless one side adjusts. In these instances, the Transactable Price represents Pexapark’s best assessment of the level at which a deal could close, based on the strongest available market signals.

While transactions are less likely to succeed during periods where there is no overlap, they can still occur in rare circumstances. For example, a seller may accept a lower PPA price if they have cost advantages or subsidies. Conversely, an offtaker might pay above the expected level if they anticipate rising power prices or seek renewable power for strategic or ESG reasons.

Yes. Many market participants use these ranges to inform pricing expectations, validate term sheets, or support internal valuation discussions. However,

deal prices may vary depending on contract structure, contract clauses and counterparties.

Ranges are provided by country, technology, and contract structure (e.g., baseload or pay-as-produced). We only display ranges for contracts where sufficient verified market evidence exists to support a transparent and credible price interval.
