What is a Power Purchase Agreement (PPA)? 

 

A Power Purchase Agreement (PPA) is a long-term contract where your business agrees to buy power directly from a specific generator – typically a solar or wind farm – at a fixed price. It's a way to take control of your energy costs while supporting the development of new renewable assets.

 

PPAs typically run for 10 to 20 years and can be structured in different ways, either with the power physically delivered to your site, or as a financial agreement that tracks market prices. What matters most is securing long-term price certainty and clean energy without tying up your own capital.

 

At Nationwide Utilities, we help large energy users cut through the complexity. From pricing models to risk allocation, we’ll guide you through the commercial, legal and operational details to structure a PPA that aligns with your business case.

Offsite PPA

Fix Your Energy Costs. Back Renewable Energy.

 

How it Works

 

You agree to buy electricity from a named solar or wind farm at a fixed price for a set number of years. The power goes into the grid, but it’s contractually linked to your business.

 

Ideal For

 

Businesses with high energy use that want price certainty and cleaner supply, without needing space for on-site generation.

 

Key Benefits

 

Cost control: Avoid wholesale market volatility with a long-term fixed rate.

Clarity: Know what you're paying and where your energy comes from.

Carbon impact: Source certified renewable power, not just a green tariff.

Stability: Build a predictable energy cost base for 10 to 20 years.


 

Onsite PPA

Clean Energy on Your Site. No Upfront Cost.

 

How it Works

 

A renewable energy developer installs and maintains a solar system on your roof or land. You pay only for the energy it produces, usually at a lower rate than your current supply.

 

Ideal For

 

Businesses with roof or land space who want cheaper, greener power without spending their own capital.

 

Key Benefits

 

No upfront cost: The developer covers design, install and equipment.

Lower bills from day one: Buy clean power at a predictable rate.

Energy independence: Use your own solar first before drawing from the grid.

Fully managed: All maintenance, insurance and servicing handled for you.

Visible sustainability: Show your commitment with on-site panels.

Flexible on ownership: Agreements can often transfer to future tenants or buyers.

Which PPA Solution is Right for Your Business? 

 

Nationwide Utilities can help you compare options to find a solution that best fits your site, budget and energy goals.

How you buy energy matters just as much as how you use it.

 

A corporate PPA lets you lock in pricing and buy directly from a renewable project. It’s a practical way to manage risk, reduce exposure to market spikes, and support new clean energy without adding to your capex.

Power Purchase Agreements

 

Power purchase agreements are long-term renewable energy agreements; usually between 5 and 20 years long. There are two different types of PPA's, that can be used for different purposes.

Offsite PPA:

Between the producer/seller of renewable power and an energy buyer.
This is an agreement between the person selling energy from their own renewable power project, and a buyer looking to purchasing energy off them.This is well-suited to those able to commit to an energy contract over a long period, accounting for a proportion of their energy usage.

  • Reduce your energy costs - A PPA contract could be 10x cheaper compared to current wholesale energy prices.

  • Reduce your carbon emissions.

  • Provides a Fixed Price (£/MWh) for the duration of the contract.

  • Budget certainty over a long period (5 - 20 years).

  • Access to an off-grid, back-up power source should power outages occur in your area

Onsite PPA: 

Between a customer installing renewable power and the developer financing the project.
This is an agreement between a customer interested in housing a renewable power system on their property, and a developer who will finance the design, installation, and maintenance of the equipment for them.

The customer will reap the benefits of access to on-site, renewable energy at a low cost but with no upfront cost to fund the project. The developer will get a return on their investment by charging the customer for their energy usage over a long-term contract and pay back period, with any spare energy being sold back to the grid or to other users looking to sign up to a PPA energy contract.

This is generally suitable for customers with the land or roof space to house the renewable power system and are large energy consumers - meaning the investor is guaranteed an easy return.

  • Implement on-site generation at zero upfront costs for your business.

  • Avoid volatile energy market and high prices.

  • No maintenance or insurance costs.

  • Immediate savings on electricity bills.

  • Green credentials and reduction in carbon at zero cost to you.

  • Transferrable to new occupiers of the property.
