Route to Market Matters: Comparing Solar Export Options

As more UK businesses invest in solar generation, attention is increasingly turning towards the different solar export options available for selling exported electricity.

While much of the conversation focuses on export rates, the route to market can have an equally important impact on the value achieved from solar generation. 

Different solar export options offer varying levels of revenue certainty, market exposure, and flexibility. As a result, selecting the right route to market is actually just as important as securing a competitive export price. 

For businesses looking to maximise solar returns, understanding the available options is an important first step. 

Why Route to Market Matters

Every exported unit of electricity must ultimately be sold into the market. 

How that electricity reaches the market determines: 

• The revenue achieved 
• Exposure to wholesale market movements 
• Contract flexibility 
• Administrative complexity 
• Long-term optimisation opportunities 

Many businesses initially default to the export arrangement offered by their electricity supplier. However, this does not often represent the most commercially advantageous route. 

As solar generation volumes increase, reviewing alternative export structures can unlock additional value. 

Option 1: Smart Export Guarantee (SEG) 

For many organisations, the Smart Export Guarantee is the most familiar export route. 

SEG tariffs allow generators to receive payment for exported electricity through participating suppliers. 

Benefits include: 

• Straightforward contract structures 
• Accessible for smaller generators 
• Predictable revenue in the short term 

However, SEG tariffs can also present limitations: 

• Fixed rates may not reflect market opportunities 
• Limited flexibility 
• Export pricing determined by supplier offerings 
• Rates may reduce over time as supplier strategies change 
• Suppliers that offer higher SEG products may not be as competitive on their import product, which means the benefit of the higher export rate is outweighed by the increased cost of importing power

Option 2: Corporate or Private Power Purchase Agreements 

Power Purchase Agreements (PPAs) provide an alternative route whereby exported electricity is sold through a dedicated contractual arrangement. 

Depending on the structure, PPAs can offer: 

• Greater pricing flexibility 
• Longer-term revenue certainty 
• Access to more sophisticated procurement structures 
• Tailored commercial arrangements 

For an increasing number of generators, PPAs can often provide greater strategic flexibility and returns than standard SEG arrangements.

Option 3: Market-Linked Export Agreements 

Some export arrangements allow generators to track wholesale market pricing more directly. 

These structures may enable businesses to benefit from favourable market conditions and periods of higher demand. 

Potential benefits include: 

Greater market participation 

• Opportunity to capture higher export values 
• Flexible procurement options 

However, market-linked arrangements can also introduce: 

• Increased revenue volatility & risk 
• Greater exposure to market movements 
• More active management requirements 

One of the most common misconceptions in solar export procurement is that there is a single “best” export route. 

In reality, the most suitable arrangement depends on factors such as: 

• Generation profile 
• Export volumes 
• Energy consumption patterns 
• Preference for revenue certainty versus market exposure 
• Commercial objectives 
• Market conditions 

An arrangement that delivers excellent value for one business may be less suitable for another. 

This is why route to market decisions should be evaluated alongside wider energy procurement and optimisation strategies. 

Unlock More Value from Your Solar Generation 

Many businesses remain on export arrangements that were put in place when their solar installation was commissioned, without reviewing whether better routes to market are now available. 

At Zerri, we help businesses compare export options, assess alternative procurement strategies, and unlock greater value from their solar generation through smarter route to market decisions.
