Power Purchase Agreements in 2025: What Boards Need to Know

Corporate energy procurement has moved from a sustainability footnote to a board-level strategic priority. Power Purchase Agreements are the mechanism. But the market in 2025 is materially different to the market of five years ago , and the risks are real.

Why PPAs are on every board agenda

Scope 2 emissions, the indirect emissions from purchased electricity, are under intense scrutiny. The Science Based Targets initiative now requires corporates to match electricity consumption with renewable energy on an hourly, not annual, basis for credible net-zero claims. That shift fundamentally changes the economics of a Power Purchase Agreement.

At the same time, energy price volatility since 2022 has made CFOs acutely interested in price certainty. A well-structured corporate PPA offers exactly that: a long-term contract for renewable electricity at a fixed or index-linked price, purchased directly from a generator rather than through the spot market. Done correctly, it simultaneously de-risks energy costs and advances sustainability commitments. Done poorly, it creates price exposure, reputational risk and contractual complexity that takes years to unwind.

The three types of PPA your team will encounter

Physical PPAs deliver electrons directly to the buyer via a private wire or the public grid. They are typically available to large energy consumers in proximity to a generation asset. They offer the purest form of renewable energy procurement but require the greatest operational complexity.

Virtual (or synthetic) PPAs are financial contracts, not physical energy deliveries. The buyer and generator agree a fixed strike price. When market prices are higher, the generator pays the difference to the buyer; when lower, the buyer pays the generator. They work for organisations with consumption spread across multiple sites and are increasingly preferred by corporate procurement teams for their flexibility.

Sleeved PPAs sit between the two: a generator sells electricity to a licensed supplier, who delivers it to the corporate buyer with matching Renewable Energy Guarantees of Origin (REGOs). They are simpler to contract but more expensive and do not offer the same price certainty as a direct VPPA.

What has changed in 2025

Three shifts are reshaping the UK PPA market. First, the pipeline of new renewable capacity has grown substantially: offshore wind, solar and battery storage projects are all seeking corporate offtake. This improves the choice available to buyers, but increases due diligence requirements. Not all developers have the balance sheet or project delivery track record to justify a 10-year contract.

Second, the UK government’s Contract for Difference regime has matured. Understanding how a CfD generator interacts with a corporate PPA, and whether a developer who wins a CfD can still offer a meaningful fixed price, requires specific regulatory knowledge.

Third, the hourly matching requirement from SBTi and emerging OFGEM guidance is forcing buyers to look at their load profile far more carefully. A flat block of renewable power does not match a 24/7 manufacturing facility or a data centre. Buyers who fail to address this will find their PPA does not deliver the Scope 2 reductions their sustainability team is claiming.

The five questions boards should ask

Does our load profile match the generation profile? Solar-heavy portfolios will not match industrial night loads. Model the match carefully before signing.

What is the basis risk? Market prices vary by settlement period and location. The difference between your contract price and the actual market price you are exposed to is your basis risk. Understand it.

Who is the counterparty? A 15-year contract is only as good as the entity on the other side of it. Credit risk, development risk and operational risk all need to be stress-tested.

What are the exit provisions? Circumstances change. A PPA with no practical exit mechanism creates real balance sheet risk if your energy consumption changes materially.

Does it actually meet our sustainability claims? REGOs, REGO-free contracting, hourly matching and additionality are not interchangeable. Be precise about what your procurement delivers and what you are claiming publicly.

Our advisory perspective

Presciense Consultative Services supports energy-intensive organisations through the full PPA process: from market analysis and load profiling to developer evaluation, term sheet negotiation and contract execution. We bring direct experience from working with UK utilities, energy-intensive manufacturers and infrastructure operators, not theoretical frameworks but practical knowledge of how these deals get done and where they go wrong.
