Power purchase agreement
Designed around you
A Power Purchase Agreement (PPA) is a contract that allows businesses and renewable energy generators to sell the electricity they produce to an energy supplier or electricity buyer at agreed rates and terms.
Our dedicated Renewables Purchasing team can tailor your Power Purchase Agreement (PPA) around your needs.
Your PPA choices
Your PPA can be as straightforward or complex as it needs to be for your site(s) – we have options for High Voltage (HV), Feed-in Tariff (FiT), Renewables Obligation (RO) locations, and more.
Fixed
Reflects market price at point of contract – then fixed
Gives you budget security and peace of mind
Lasts 1 to 3 years
Ideal for smaller FiT and RO sites
Flex
For larger generators, often with predictable output
Staged selling at quoted market price capturing volatility
Lasts 1 to 3 years
Also for HV, FiT, and RO sites
Bespoke
Fixed or indexed price, seasons, peak or off-peak
Choose the route to market that’s best for your needs
Variable contract lengths
For HV, FiT, and RO sites
We partner with over 2300 renewable energy generators across the UK

The complete guide to PPAs
Our new guide explains how Power Purchase Agreements (PPAs) work, which structure is best for you, and how to avoid hidden costs.
How to start selling electricity
Our guide to generating renewable electricity aims to simplify the process and help you get from installation to payment.
What are ROCs?
Renewables Obligation Certificates (ROCs) are green-energy certificates issued for eligible renewable electricity generated within the UK. We’re able to buy ROCs you may be looking to trade outside of your PPA.
Providing high-level service to our customers
We’ve achieved the highest possible rating in Ofgem’s latest supplier compliance audit which applies to our Feed-in Tariff (FiT).
On top of this, we achieved an Ofgem meter verification rate of greater than 95% since early 2020. This is around 20% higher than the industry average.

Power Purchase Agreements - FAQs
Who can benefit from a Power Purchase Agreement?
Businesses, farms, commercial property owners and renewable energy generators that produce more electricity than they consume can benefit from a PPA by earning revenue from excess power generation.
What types of renewable energy projects qualify for a PPA?
Power Purchase Agreements are commonly available for solar, wind, hydro, biomass, anaerobic digestion and other renewable generation technologies, depending on the supplier and project size.
What is the difference between a fixed-rate and flexible PPA?
A fixed-rate PPA offers a predetermined price for exported electricity, providing revenue certainty. A flexible or variable-rate PPA may track wholesale market prices, offering potential upside when energy prices rise.
Can I use my renewable electricity and sell the excess through a PPA?
Yes. Many PPAs allow generators to use the electricity they need on-site while exporting surplus power to the grid, helping maximise the value of renewable energy investments.
Why are Power Purchase Agreements important for renewable energy projects?
PPAs provide a route to market for renewable electricity, helping generators create additional revenue streams while supporting the UK's transition to a lower-carbon energy system.
