Short answer
How high is the PV feed-in tariff in Thurgau in 2026?
For a PV feed-in tariff in Thurgau, first verify the specific grid area. In the Thurplus grid area, the quarterly SFOE reference market price has applied since 1 January 2026; Thurplus also states a 6 Rp./kWh minimum remuneration for PV systems up to 30 kW. Before calculating economics, clarify the grid area, voltage level, system size, self-consumption and separate guarantees of origin.
Important
As of 25 August 2026, the SFOE reference market price varies by quarter and the Thurplus feed-in route does not automatically apply throughout the canton. For Q3 2026, the SFOE lists 14 October 2026 as the publication date; that value must not be anticipated. The binding points are the grid area, the current SFOE value and the conditions of the responsible grid operator.

Decision points
What determines the right path.
Grid area rather than cantonal boundary: the Thurplus rule applies to the Thurplus grid area in Frauenfeld. If the property is served by another distribution-grid operator, its registration, metering and contractual conditions may differ; record the responsible operator before making any tariff assumption.
Price logic from 1 January 2026: the SFOE describes the quarterly reference market price as the harmonised Swiss price under Art. 15 para. 1 EnG when the grid operator and producer do not agree on remuneration. An annual figure from an old Thurplus tariff table is therefore not a reliable 2026 assumption.
Output class: Thurplus states 6 Rp./kWh for solar systems up to 30 kW and 6 Rp./kWh for the first 30 kW of systems between 30 and 150 kW with self-consumption. Compare the kW threshold with total installed output, not with the expected exported energy.
Voltage level and size: under its published rules, Thurplus remunerates systems in the low-voltage grid; medium-voltage systems require individual agreements. Thurplus also names 3.0 MWp or 5,000 MWh as the limit of the described feed-in route.
Self-consumption before feed-in: Thurplus itself points out that high self-consumption, storage or dynamic load management changes how solar power is allocated. The load profile, heat pump, wallbox and battery must therefore be modelled before comparing the result with the SFOE price.
Keep revenue streams separate: feed-in remuneration is settled per exported kilowatt-hour, while the Pronovo EIV is a separate federal instrument supporting the investment. Thurplus also mentions payment for guarantees of origin as an additional remuneration; these three items must not be merged into one flat solar-yield figure in the quote.
Sequence
How the project stays cleanly managed.
- 1
Confirm the grid areabefore the quote, use the address and grid connection point to establish whether Thurplus or another distribution-grid operator is responsible. For Frauenfeld, Thurplus’s solar feed-in page is the concrete starting point; the canton alone does not answer this question.
- 2
Classify the systemrecord installed output, expected annual production and voltage level. The 30 kW and 150 kW thresholds, together with the 3.0 MWp or 5,000 MWh limits named by Thurplus, determine whether the published standard logic is sufficient or another contractual route is needed.
- 3
Prepare metering and registrationregister the PV system with the responsible grid operator and clarify the technical connection. Thurplus requires a registered, technically correct system for remuneration and installs suitable metering where necessary.
- 4
Calculate self-consumptioncompare the load profile, heat pump, wallbox and battery with feed-in. Use the current SFOE reference market price for the exported share; the SFOE publishes it by the 10th working day after the quarter ends, not as a fixed annual figure.
- 5
Register funding separatelykeep the Pronovo EIV as an investment contribution separate from feed-in remuneration and any guarantees-of-origin payment. The current SFOE funding page refers to Pronovo for registration; show the three cash-flow elements as separate lines in the economic calculation.
- 6
Document commissioningkeep the grid registration, metering concept, technical data and actual installed output consistent. For medium voltage or a system outside Thurplus’s standard limits, an individual agreement or written clarification must be in place before execution.
Checklist
Questions to settle before the quote.
- Identify the Thurplus grid area in Frauenfeld and the actual distribution-grid operator before requesting a quote
- Include the 6 Rp./kWh rate up to 30 kW and the 30-to-150-kW rule for systems with self-consumption in the calculation
- Keep the SFOE reference market price, self-consumption, storage and separate guarantees of origin as distinct revenue or value components
- Prepare registration, metering, the Pronovo EIV and any medium-voltage agreement in the correct sequence
