Background
#The PV feed-in tariff in Schaffhausen follows the Swiss Federal Office of Energy (SFOE) quarterly reference market price in the SH POWER grid area in 2026; systems up to 30 kW receive a minimum of 6.00 Rp./kWh.
For SH POWER, 10.27 Rp./kWh for the first quarter and 3.90 Rp./kWh for the second quarter have been published, both excluding VAT. The third-quarter value will only be published on 14 October 2026 at 12:00 and must not be anticipated. A different grid operator, a system above 30 kW or a medium-voltage connection requires further clarification.
Guarantees of origin are remunerated separately and handled through an SH POWER agreement from 4 kW, while the Pronovo one-time incentive is a separate funding route.
What drives the economics
#The grid area is the first decision point. The published tariff schedule belongs to SH POWER and applies to feed-in to its grid; Canton Schaffhausen alone does not determine the feed-in tariff. Before quoting, assign the address to the responsible distribution-grid operator.
Since 1 January 2026, the quarterly reference market price under Art. 15 para. 1 EnG replaces a flat annual value where the producer and grid operator do not agree on remuneration. The SFOE publishes the price by 12:00 on the 10th working day after each quarter; Q3 2026 follows on 14 October 2026.
Installed PV output is the decisive quantity. SH POWER states a 6.00 Rp./kWh minimum up to 30 kW; for systems from 30 to 150 kW with self-consumption, the tariff schedule reduces the output-dependent minimum under the formula 180 divided by system output in kW, for example to 3.00 Rp./kWh at 60 kW.
Self-consumption changes the quantity, not automatically the tariff. A heat pump, wallbox, battery or ZEV reduces the surplus that is remunerated at all. For the remaining feed-in, SH POWER’s published SFOE values of 10.27 Rp./kWh for Q1 and 3.90 Rp./kWh for Q2 2026 are the concrete comparison points.
Guarantees of origin are a separate revenue stream. SH POWER states 2.50 Rp./kWh for guarantees of origin; for systems from 0 to 4 kW this amount is settled automatically with the feed-in tariff, while from 4 kW a separate purchase agreement, certification and registration in the Pronovo system are required.
Timing and the tax basis belong in the revenue calculation. SH POWER’s 2026 tariff schedule states feed-in and guarantees-of-origin remuneration generally excluding VAT; switching to HKN remuneration must be notified two months before the quarter starts and the Pronovo standing order confirmed no later than 14 days before the change.
The process in six steps
#Tick off for your project
Establish the grid area and metering point
record the address, grid connection point and responsible distribution-grid operator in the project file. The following tariff schedule is relevant only where SH POWER purchases the electricity; elsewhere, use the other operator’s current feed-in rules.
Classify the system
calculate installed DC output, voltage level, expected annual generation and self-consumption share. Up to 30 kW, the 6.00 Rp. minimum applies; from 30 to 150 kW with self-consumption, also check the formula 180 divided by system output, while above 150 kW the tariff schedule states a 0.00 Rp./kWh minimum.
Prepare metering and registration
align the technical data, connection request, metering concept and actual installed output with SH POWER. A medium-voltage connection or output outside the published standard classes should only be included in the quote after written clarification with the grid operator.
Model self-consumption
compare the load profile, heat pump, wallbox, battery and any ZEV or LEG structure with PV generation. Only the remaining surplus is valued at the relevant quarterly rate; the SFOE publication is exclusive of VAT and is not a fixed annual price.
Calculate feed-in, guarantees of origin and funding separately
SH POWER lists 2.50 Rp./kWh for guarantees of origin, while Pronovo handles the one-time incentive as federal funding. The economic calculation should show at least self-consumption value, feed-in, guarantees of origin and Pronovo RU as separate lines.
Trigger the guarantees-of-origin agreement and deadlines only where needed: for systems from 4 kW, certify the system data, register the system in Pronovo’s guarantees-of-origin system and request the SH POWER change two months before the quarter starts. The producer must confirm the Pronovo standing order no later than 14 days before the change.
Checked for your roof, not just read up on
Once the framing is clear, a property-specific check with roof, grid and documentation is worthwhile.
