Short answer
How much is the battery-storage incentive in Thurgau in 2026?
In Thurgau, the 2026 cantonal contribution is CHF 1,000 per stationary battery, capped at 25% of total investment. Eligible batteries serve existing or planned grid-connected PV systems and provide at least 10 kWh usable capacity; the application must be filed before installation. The 700-application quota is full, so new applications join a waiting list by receipt date.
Important
As of 2026, Thurgau's battery-storage incentive is not freely available: the 700-application quota is full and further submissions are kept on a waiting list. The waiting list is not a funding commitment; consideration in 2027 depends on the programme continuing. Anyone installing before approval bears that risk.

Decision points
What determines the right path.
The grant is capped: the programme provides CHF 1,000 as a one-time investment contribution per system, but no more than 25% of the total investment in the supported measure. A more expensive battery therefore does not increase the cantonal contribution beyond these two limits.
Usable capacity determines basic eligibility: the stationary battery must provide at least 10 kWh of usable capacity and be linked to an existing or planned grid-connected solar-electric system. A standalone battery without this PV connection does not fit funding category 7.1.
An extension has an additional hurdle: the newly installed battery capacity must also be at least 10 kWh, and the initial installation must have been funded at least three years earlier. A small retrofit or a battery replaced too soon does not meet this condition.
The receipt date is practically decisive in 2026: the category is limited to 700 applications, and the date of submission determines consideration. The funding programme states that this quota has already been reached and that further applications are kept on a waiting list by receipt date.
Starting before the decision remains a separate risk: the application must be filed before installation begins. Anyone who installs before the funding approval does so at their own risk under the programme; the waiting list is not a commitment because 2027 support depends on the programme continuing.
The future operating model belongs in the quote: the canton expects the operator to make 10% of the storage capacity available to the electricity utility on request for compensation; neighbourhood storage is excluded from this expectation. Clarify this point with the specific utility and the battery control system before ordering.
Sequence
How the project stays cleanly managed.
- 1
Classify the funding categorydocument the Thurgau location, existing or planned grid-connected PV system, stationary battery and at least 10 kWh of usable capacity. For an extension, also record the new capacity and the date of the initial funding.
- 2
Align the technical option and coststhe quote must show usable capacity, total investment, specialist installation and the planned battery control system. Calculate the CHF 1,000 amount and the 25% cap separately, and record the expected 10% availability for the utility.
- 3
Prepare the documents completelyalign the PV system, battery, usable capacity, quote and installation start. The Energy Office directs funding applications and project completions to the energy funding portal; electronic submission has applied since 1 January 2021.
- 4
File before installation startssubmit the funding application before fitting the battery and retain the receipt date. For 2026, the 700-application quota is already full, so a new submission is placed on the waiting list by its receipt date.
- 5
Decide on the approval and installation riskwait for the funding approval if eligibility is needed for the investment decision. If installation starts earlier, the programme places it at the owner's risk; a later award on the waiting list is possible only if the programme continues in 2027.
- 6
Document installation and align operationhave the battery installed by a recognised specialist, retain the application, quote and system data, and clarify the expected 10% availability with the utility. The technical installation must match the submitted storage capacity.
Checklist
Questions to settle before the quote.
- Calculate the CHF 1,000 grant and the 25% of total investment cap separately
- Check at least 10 kWh of usable capacity and the three-year rule for extensions
- Classify the 700-application quota, receipt date and waiting list for 2026
- File before installation starts and account for the expected 10% capacity availability for the utility
