If your business generates renewable energy and is exploring options for selling surplus electricity, you’ll likely encounter two main routes: the Smart Export Guarantee (SEG) and Export Power Purchase Agreements (PPAs). While both can help you monetise your excess energy, each comes with unique features that cater to different business needs.
Understanding the Basics
| Feature | SEG | PPA |
| Definition | A government-backed scheme requiring electricity suppliers to pay for exported renewable energy. | A contractual agreement with an energy supplier or buyer to sell surplus renewable energy. |
| Eligibility | Business in England, Scotland, or Wales with qualifying renewable technologies (e.g. solar, wind) | Renewable energy producers meeting offtaker-specific requirements. |
| Pricing | Variable; rates set by individual suppliers and can fluctuate. | Negotiated rates, often fixed or market-linked, offering pricing certainty. |
| Contract Length | Short-term, with flexibility to switch suppliers or tariffs. | Typically long-term agreements (5-20 years), tailored to business needs. |
| Application Process | Requires signup with a supplier offering an SEG tariff. | Involves negotiation and agreement with an offtaker or energy buyer. |
Key Considerations
Smart Export Guarantee (SEG):
- Pros: Simple process, no long-term commitment, ideal for small-scale producers.
- Cons: Rates may be lower or inconsistent compared to Export PPAs, offering less revenue stability.
Export Power Purchase Agreement (PPA):
- Pros: Competitive rates, price stability, suited for larger-scale producers or businesses focused on long-term planning.
- Cons: May require higher upfront effort for negotiation and setup.
What’s Right for Your Business?
The choice between SEG and Export PPAs depends on your business goals, energy production capacity, and financial priorities. Here’s a quick guide:
- Choose SEG if… you’re a small-scale producer looking for flexibility and a straightforward way to sell excess energy. SEG is perfect for businesses with modest energy production and no need for long-term commitments.
- Choose Export PPA if… you generate significant surplus energy and want pricing stability over a longer term. PPAs are ideal for businesses seeking to optimise revenue, secure predictable cash flow, and align energy sales with strategic goals.
