What Is a Corporate PPA? A Practical Guide for UK Businesses
Energy costs can be hard to predict and manage because of a range of external factors. As a business, you’ll want more cost certainty so you can manage cash flow and plan with greater confidence. At the same time, businesses like yours are expected to demonstrate strong progress on sustainability, which often poses challenges. In this blog, we’re looking at what a corporate PPA is.
What is a corporate PPA?
A corporate PPA is a long-term agreement that allows a business to purchase electricity from, or enter into an arrangement linked to, a renewable energy generation project.
The exact structure can vary. For example, a sleeved PPA uses a licensed supplier to incorporate the contracted generation into the customer's wider electricity supply. Meanwhile, a virtual PPA is a financial arrangement rather than a physical supply of electricity.
Corporate PPAs (power purchase agreements) can help address energy costs and sustainability challenges by giving businesses a long-term renewable energy solution.
Using a corporate power purchase agreement can be highly beneficial, as it can provide greater predictability around future costs, a route to procuring electricity from renewable generation, and a clearer link between energy procurement and sustainability objectives.
This can give your business greater visibility over energy costs and reduce exposure to some wholesale market movements. They may also allow your organisation to support renewable energy generation projects. Read more about our support for renewable electricity procurement.
Corporate PPAs can be long-term agreements, with contract lengths varying considerably depending on the project and structure.
What are the benefits of a corporate PPA?
Greater certainty over energy costs
While a PPA doesn’t guarantee lower energy prices, it does offer greater pricing predictability, giving you more control and clarity and helping you stabilise energy costs.
Reduce exposure to market volatility
Energy market volatility can make it difficult to forecast future costs and plan effectively. A PPA can allow you to agree pricing arrangements over a longer period, helping to reduce some of this uncertainty.
Strengthen your renewable energy strategy
If your business is working towards a more sustainable energy strategy, then it’s highly likely that you’re looking at renewable energy solutions. A renewable PPA can help a business increase its exposure to renewable generation and support wider ESG, renewable energy or decarbonisation objectives, depending on the agreement's structure.
Better long-term planning
Planning helps you stay proactive, not reactive. A long-term plan gives you a clear strategic direction for your energy procurement.
Potential financial benefits of a corporate PPA
- More predictability, allowing for better planning
- Reduced exposure to market volatility
- Better budgeting for the future
Sustainability benefits of a corporate PPA
- Allows you to demonstrate sustainability progress
- Supports broader net-zero goals
- Increases visibility for electricity sourcing
- Can support investment in renewable energy generation
- Strengthens sustainability reporting and stakeholder communications
What is a corporate renewable PPA?
A corporate renewable power purchase agreement involves renewable energy generation, commonly wind and solar projects. These can help you achieve the following benefits.
- Build a long-term strategy with renewable energy
- Increase the amount of renewable energy in your procurement strategy
- Support your sustainability efforts
- Improve visibility of your future energy strategy
- Potentially secure other renewable attributes, such as REGOs
How do corporate PPA contracts work?
1. Identify your energy requirements
Before you get started with a corporate PPA, you need to understand exactly how much energy your organisation uses and when. This will enable you to understand the true benefits and set up a strategy that works for you.
2. Find a suitable renewable generation project
Once you know your business's energy use, you need to find a suitable renewable generation project. In most cases, new renewable energy projects involve wind or solar power.
3. Agree on the commercial terms
A contract must be put in place for a corporate PPA. This contract should outline pricing, duration, volumes and renewable attributes.
4. Arrange the electricity supply and sleeving structure
Once the PPA is agreed, you need to put the electricity supply arrangements in place. Depending on the structure, this may involve a licensed supplier sleeving the contracted generation into your wider electricity supply.
5. Account for differences between generation and consumption
Renewable generation will not always match your business's electricity demand. Your supply arrangements therefore need to account for periods when generation is higher or lower than your consumption.
A key consideration when structuring a PPA is how the agreement fits with the way your business actually uses energy, rather than taking a one-size-fits-all approach.
What is a sleeved PPA in the UK?
A sleeved PPA is an arrangement where a business agrees to purchase electricity generated by a renewable project, with a licensed electricity supplier managing the process of bringing that contracted generation into the business's wider electricity supply.
This can make renewable generation more practical for businesses that still need a reliable electricity supply when the contracted renewable project is not generating enough electricity to meet their demand.
How much could a corporate PPA save your business?
A corporate PPA does not necessarily lead to savings in every case, but it can provide greater clarity over energy costs and reduce exposure to some energy price volatility. The exact financial value of your strategy depends on many factors, including the following.
- Agreed PPA pricing structure
- Wholesale market conditions
- Contract length
- Business consumption profile
- Generation profile
- Supplier/sleeving costs
- Potential embedded benefits, where applicable
- Value of renewable certificates, such as REGOs, where included in the agreement
- Volume and balancing arrangements
When considering a corporate PPA, it’s not always right to focus on price alone. Instead, it’s about identifying whether it provides the right balance of risk, price, flexibility and sustainability value for your business.
What are the risks involved with a corporate PPA?
As with any business decision, it’s important to recognise the risks involved. Understanding these risks from the outset can help you plan more effectively and put appropriate measures in place to manage them.
Long-term commitment
PPAs are typically long-term arrangements, although contract lengths can vary considerably depending on the project and structure.
With this in mind, it’s important to understand your long-term goals and requirements. If your electricity requirements are likely to change substantially, then a PPA may not be suitable.
Volume risks
A sleeved structure can help manage the practical differences between contracted generation and your consumption. However, your supply arrangements still need to account for periods when your business uses more or less electricity than expected.
Market risks
Market volatility is a challenge, and by locking into a PPA, you have to accept the fact that prices may fall at some point. This could mean you pay more under a fixed price than you would if you accepted market risk and didn't require pricing certainty. However, you will remove some of the seasonal volatility associated with the wholesale energy markets,
Energy generation risks
Energy generation can vary depending on a range of factors. Typically, wind and solar output varies throughout the year, so you need to be prepared for these additional risks, especially if you are in an energy-intensive industry.
It’s also important to recognise that PPAs often contain detailed commercial, legal and energy market terms. The key to securing a robust corporate PPA is ensuring that it works for you, not by signing one that doesn’t meet your requirements.
Is a corporate PPA right for your business?
If you’re debating whether or not a corporate PPA could work for your business, then you should consider the following.
A PPA could be worth exploring if you:
- Have significant electricity consumption
- Want greater long-term price visibility
- Have clear renewable energy goals that support your wider decarbonisation strategy
- Can commit to a longer-term contract
- Have a reasonably predictable consumption profile
- Want to take a more strategic approach to energy procurement
You may need to consider other options if you:
- Have highly unpredictable electricity consumption
- Need maximum short-term flexibility
- Aren't comfortable with a long-term contractual commitment
- Don't consume enough electricity for a particular PPA structure to make commercial sense
From a financial standpoint, you can ask the following questions.
- How much electricity do you actually use, and when?
- What are you paying today for energy costs?
- Are you expanding, relocating or electrifying processes in the future?
- How much price certainty do you want versus flexibility?
- How important is renewable electricity to your wider strategy?
Remember, there is no right or wrong answer when choosing a corporate PPA strategy or a traditional energy strategy. The right choice depends entirely on your energy usage, financial priorities, and whether you want to lock into a long-term commitment.
What if a corporate PPA isn't the right fit?
A corporate PPA isn't the only way for a business to access renewable energy.
If a PPA doesn't align with your consumption profile, risk appetite, contractual requirements or want for a long-term commitment, there are other approaches to consider. The most suitable option depends on what you're trying to achieve, whether that's increasing renewable electricity procurement, supporting sustainability objectives, managing energy costs or finding greater flexibility.
This is where it helps to consider your wider renewable energy strategy, rather than focusing on a PPA alone.
