Power Purchase Agreements (PPAs) were once limited to energy experts or procurement teams in large multinational companies. This is changing quickly. PPAs are now more common among large corporations and are becoming accessible to smaller and mid-sized businesses. This shift is significant.
What Are PPAs and Why They Matter
Let’s start with the basics: a Power Purchase Agreement (PPA) is a long-term contract between a power producer (often a renewable energy developer) and a buyer (usually a company), locking in a fixed electricity price over several years. Simple enough in theory, but historically complex in execution.
PPAs provide stability and certainty in an increasingly volatile energy market. In a time of rising prices, regulatory pressure, and growing scrutiny on carbon emissions, they offer both financial predictability and a clear sustainability impact.
Traditional PPAs involved long-term commitments, complex negotiations, and significant due diligence. These requirements do not suit most mid-market businesses. The PPA model has changed to address this.
We’ve worked with clients across the manufacturing, retail, logistics, and property sectors to shape bespoke agreements that align with their size, energy demand, and risk appetite. The result? A contract that delivers carbon savings and cost control — without tying the business into something it can’t sustain.
Structured PPAs: Designed to Manage Risk, Not Add It
Renewable generation brings huge sustainability benefits, but it also introduces intermittency — the sun doesn’t always shine, and the wind doesn’t always blow when demand peaks. That’s why structured and hybrid PPAs are playing a bigger role.
Structured PPAs use a mix of technologies, such as wind, solar, and storage, or adjust delivery profiles to better match generation with consumption. This approach provides a more predictable supply of clean energy and reduces exposure to market volatility.
These models combine wind, solar, and battery storage to create a more stable delivery profile for renewable energy. This reduces price risk for buyers and improves grid reliability. The result is a more stable and tailored energy supply.
There’s also proxy generation. A model that pays the generator based on expected output rather than real-time production. This reduces complexity and eliminates the need for real-time tracking and settlement. For buyers, it means less exposure to imbalance charges and a more predictable energy cost.
They are designed to be easier to use, more cost-predictable, and more attractive for smaller buyers.
How the UK and Europe Are Driving Corporate PPA Growth
The UK corporate PPA market has changed significantly in the past two years. Demand is increasing due to net-zero strategies, higher grid costs, and better developer offerings.
According to energy data platforms such as Pexapark and Veyt, corporate buying has shown strong, consistent growth across Europe, with the UK emerging as one of the most active national markets. Part of that success comes from a combination of factors: progressive corporate climate commitments, a well-developed renewables industry, and financial innovation.
We’re seeing strong appetite from both sides of the market: developers looking for diversified offtake routes, and mid-sized corporates eager to fix long-term costs while hitting decarbonisation goals.
The change is not only in volume but also in the sophistication of PPA structures. The UK is now testing new commercial models that fit the needs of smaller businesses. Shorter contract terms, simplified settlement, and credit solutions for companies without investment-grade ratings are now available.
From Corporate Giants to the Mid-Market: A Big Shift
If there’s one thing we’ve learned from working with mid-sized businesses, it’s that flexibility matters. No two operations are the same, and neither are their energy strategies.
Aggregated PPAs
Sleeved PPAs
What the Mid-Market Needs: Simpler, Shorter, Smarter
- Shorter terms: 5–10 year terms that align with corporate planning cycles.
- Simplified credit options: Partnering with insurers and financiers to mitigate credit risk, without overburdening the client.
- Clear commercial benefit: Price certainty, hedging value, and measurable emissions reductions; backed by robust reporting.
- Ease of integration: Whether through sleeving, supply agreements or REGO-backed structures, we prioritise seamless integration with existing operations.
Digital tools also play a part. From early-stage modelling and scenario planning to post-contract monitoring and reporting, we provide end-to-end transparency, so clients can make decisions with confidence.
A More Inclusive PPA Market Is Already Here
FAQs
Yes. Thanks to innovations like aggregated and sleeved PPAs, even smaller companies can now participate in renewable energy deals with manageable contract terms and risk profiles.
An aggregated PPA combines demand from several buyers into a single agreement, making it easier for smaller businesses to access the benefits of a PPA without going it alone.
3. Are PPAs risky for businesses without a credit rating?
New models are emerging to manage credit risk—such as insurance-backed contracts, pooled credit assessments, or using a parent company guarantee. These tools are helping more businesses qualify.
4. What’s the typical length of a mid-market PPA?
5. How long does it take to get a PPA in place?
