Smart Export Guarantee — Best Tariffs for FE College Solar Exports in 2026
Comparing Smart Export Guarantee tariffs for FE college solar projects. Octopus, E.ON Next, EDF, Scottish Power, OVO and others ranked for non-domestic export.
Smart Export Guarantee (SEG) is the regulated mechanism that pays solar generators for electricity exported to the grid. For FE colleges with strong self-consumption profiles, SEG is a smaller fraction of total project value than for residential installs — but on summer holiday weekends and Saturdays, export can still be substantial, and choosing the right SEG licensee matters.
How SEG works for FE colleges
Every solar installation up to 5 MW is eligible for SEG. The DNO measures exported electricity through a smart meter or compliant interval meter, the SEG licensee receives the data, and the FE corporation receives a quarterly or monthly export payment.
SEG licensees are obliged to offer a tariff but the rate is unregulated — competitive pricing varies from around 4p/kWh to around 12p/kWh (as at June 2026) depending on the licensee, the tariff structure, and the import-export bundling. Rates move on roughly 30 days’ notice, so verify the live figure before contracting. For FE corporations with strong daytime self-consumption (typically 55-75%), SEG payments are 15-30% of total project value — meaningful but not dominant.
Best SEG tariffs for FE colleges in 2026
Six SEG licensees worth comparing for non-domestic FE college exports:
1. Octopus Energy Outgoing Fixed and Outgoing Agile
Octopus offers both flat-rate and variable export products. The flat-rate option (Outgoing Fixed for domestic-scale generators; Panel Power for business export) pays 12p/kWh as at June 2026 — the rate was cut from 15p on 1 March 2026, so treat any 15p quote as stale. Outgoing Agile pays a half-hourly variable rate linked to wholesale prices, often delivering higher value during summer-evening windows when export is high.
Octopus typically requires a matched import tariff with them, which can be a constraint where the FE corporation has a fixed-term commercial supply contract elsewhere.
2. E.ON Next Export Exclusive
E.ON Next’s standalone SEG pays a competitive flat rate (around 10-11p/kWh as at June 2026; its higher headline rates require import bundling). Particularly suitable for FE corporations on multi-year fixed-term import contracts with different suppliers.
3. EDF Energy SEG
EDF’s SEG tariff is more modest (typically 6-8p/kWh) but available without complex bundling requirements. Often a good fit for FE corporations already on an EDF commercial import contract.
4. ScottishPower SEG
ScottishPower offers SEG at around 8-10p/kWh for non-domestic generators. Standard contract terms; reasonable for FE estates in Scotland and Wales where ScottishPower is the established commercial provider.
5. OVO Energy SEG
OVO’s non-domestic SEG offering is around 6-10p/kWh depending on tariff variant. Generally competitive for smaller commercial generators.
6. Pozitive Energy and similar specialist SEG providers
A handful of specialist SEG-only providers (Pozitive Energy, Tomato Energy, Outfox the Market) offer competitive tariffs without import bundling requirements. Worth comparing quarterly as tariffs move.
Choosing the right SEG licensee
Three decision factors:
1. Import contract bundling
If the FE corporation can move its commercial import contract to Octopus, its 12p/kWh flat export rate (as at June 2026) is among the strongest standard tariffs. If the import contract is locked to a different supplier for multiple years, a standalone SEG such as E.ON Next’s or Good Energy’s is the typical alternative — competitive rate, no bundling requirement.
2. Fixed vs Agile pricing
Outgoing Agile (Octopus) and similar half-hourly variable products can deliver higher value where the FE site has strong summer-evening or weekend export patterns. Residential SDIs, land-based colleges with summer evening farm load, and sites with significant Saturday daytime export all benefit. Pure term-time-only sixth form colleges typically benefit less from Agile.
3. Settlement and reporting
SEG payments are typically monthly or quarterly. Reporting quality varies — Octopus and E.ON Next offer better dashboards and CSV export than some legacy suppliers. For corporations reporting to the AoC Climate Action Plan or EAUC Sustainability Leadership Scorecard, easy data extraction matters.
SEG and Triad considerations
Smart Export Guarantee is separate from Triad payments — the (now phased-out) mechanism whereby half-hourly metered commercial sites earned demand-reduction payments for reducing import at the three highest-demand winter half-hours. Triad is being replaced by the Demand Flexibility Service (DFS) and the Balancing Mechanism reforms; FE colleges with battery storage may participate in DFS or other emerging grid services for additional revenue. Worth discussing with your monitoring platform provider.
SEG and Smart Meter requirements
To claim SEG, the FE corporation needs a smart meter or compliant interval meter that records half-hourly export data. Most modern FE estates already have this in place — the SEG registration process typically just confirms the export channel and signs up the SEG licensee.
For older estates with traditional meters, a meter upgrade may be needed — typically a 4-8 week process initiated by the DNO. The cost is usually zero (DNOs replace meters on request as part of the smart meter roll-out) but the lead time should be in the project schedule.
Annual SEG income estimates
Typical annual SEG income for FE college solar installs:
- 180 kW PV on a sixth form college, 50% self-consumption: roughly £8,000-£10,000 per year SEG income (10-12p/kWh on ~85,000 kWh exported)
- 280 kW PV on a general FE main campus, 60% self-consumption: roughly £10,000-£13,000 per year SEG income
- 850 kW PV on a land-based college, 75% self-consumption: roughly £20,000-£24,000 per year SEG income (high generation × low export percentage keeps SEG secondary despite the large system)
- 1.6 MW portfolio across 8 group corp campuses, 70% self-consumption: roughly £45,000-£55,000 per year aggregated SEG income
All figures assume a ~950 kWh/kWp annual yield and a 10-12p/kWh flat SEG rate (as at June 2026) — recheck live rates before building them into a business case.
In every case, SEG is a meaningful but secondary contribution to total project value. The dominant economics come from avoided grid import cost (self-consumption × ~25p/kWh), not from export.
