Everything you need to know about remuneration for solar energy and other electricity feed-in tariffs
Find out here about the current remuneration rates for electricity fed into the grid from your system and other relevant information about your photovoltaic system.
How will the feed-in of your solar power be remunerated from 2026 onwards?
The remuneration for solar energy or hydroelectric power fed into the grid is based on the reference market prices calculated by the Swiss Federal Office of Energy (SFOE) in accordance with Article 15 of the Energy Ordinance (EnFV). These prices are revised monthly and quarterly and can be viewed on the SFOE website. According to the SFOE, the reference market price represents the average of the day-ahead prices traded on the Swissix electricity exchange in the respective month/quarter. This is weighted according to the actual quarter-hourly feed-in from plants with load profile measurement. The remuneration for the electricity from your plant is only determined after the end of a quarter. The reference market price for a quarter is decisive for the remuneration. For the remuneration of electricity from fossil and partially fossil-fired combined heat and power plants, the market price is based on the hourly prices on the spot market in day-ahead trading for the Swiss market area.
Following the clear yes to the new Electricity Act, uniform rules for electricity procurement within the framework of the procurement and remuneration obligation will apply throughout Switzerland from 2026. These also include minimum remuneration for systems with a capacity of less than 150 kW. The aim of this minimum remuneration is to ensure that a PV system can pay for itself over its lifetime, even when market prices are low.
For installations with a capacity of less than 150 kW, the following minimum remuneration shall be granted in accordance with Article 12(1)bis of the EnFV:
| Plant size | Minimum remuneration |
|---|---|
Systems with a capacity of less than 30 kW | 6.00 pence/kWh |
Systems with own consumption and an output of 30 kW or more | 1.20 – 6.00 pence/kWh |
Installations sans consommation propre d'une puissance supérieure à 30 kW | 6.20 Rp/kWh |
Hydroelectric power stations | 12,00 Rp./kWh |
Remuneration for guarantees of origin
Primeo Energie offers all operators of photovoltaic systems or other renewable energy production facilities the opportunity to transfer guarantees of origin to Primeo Energie. The remuneration for guarantees of origin is determined quarterly based on market prices and amounts to a maximum of 2 pence/kWh.
Prices for auxiliary power supply
Depending on the technology, energy generation systems consume more or less electrical energy, which is often referred to as auxiliary energy. If you have decide to feed all of the electricity produced into Primeo Energie’s distribution system, a direct feed-in exists (also known as Metering Principle A).

Frequently Asked Questions
The obligation to purchase and remunerate means that, as a grid operator, we are obliged to purchase the energy you produce and remunerate you appropriately. As a producer, you are free to decide to whom you wish to supply the energy you generate.
The remuneration amount will only be announced after the end of a quarter. The remuneration for electricity fed into the grid is now based on the reference market price. This is calculated and published by the Federal Office of Energy in the second week after the end of each quarter. For the first quarter of 2026, this will be in mid-April 2026.
In winter, the reference market price is usually higher due to higher electricity demand and scarcer supply. In sunny quarters, it falls due to lower demand and higher supply. To protect against low market prices in summer, the Energy Act guarantees a minimum remuneration of 6 pence/kWh for systems with a capacity of up to 30 kWp.
The following remuneration rates were last published:
2024
Q1: 6.2 Rp./kWh
Q2: 3.5 Rp./kWh – The minimum remuneration is paid at this reference market price.
Q3: 3.3 Rp./kWh – The minimum remuneration is paid at this reference market price.
Q4: 8.8 Rp./kWh
2025
Q1: 10.4 Rp./kWh
Q2: 2.8 Rp./kWh – The minimum remuneration is paid at this reference market price.
Q3: 5.7 Rp./kWh – The minimum remuneration is paid at this reference market price.
The reference market price is the quarterly average market price and corresponds to the average of the prices set on the electricity exchange for the following day for the Swiss market area, weighted according to the actual quarter-hourly feed-in of the load-curve-measured plants of the respective technology.
The reference market price is published by the Swiss Federal Office of Energy (SFOE) in the middle of the following month after the end of a month or quarter. The reference market price for a quarter always determines the remuneration for electricity from your production facility. This means that the remuneration for your energy is only known retrospectively.
The remuneration is determined based on market prices. If these fall, the feed-in tariffs also fall. If market prices rise, the remuneration for the electricity fed into the grid also rises.
Energy legislation provides for a harmonised remuneration across Switzerland from 2026 onwards, based on the quarterly average market price at the time of feed-in. Primeo Energie and AVAG will remunerate the electricity fed into the grid from 2026 onwards according to this so-called reference market price, which will be calculated and published by the Federal Office of Energy at the end of each quarter. The corresponding Electricity Act was approved by the Swiss electorate on 9 June 2024.
Yes, for systems billed monthly, remuneration will continue to be paid monthly. The first two months of a quarter are billed according to the monthly reference market price. In the third month of the quarter, the final bill for the entire quarter is issued using the relevant quarterly reference market price and any corrections for the first two months. As with the quarterly reference market price, the monthly reference market prices are published two weeks after the end of each month.

If you make greater use of the production peaks around midday to cover your own consumption and your photovoltaic system has a production focus in winter, you can increase the yield of your PV system by up to 30 per cent. You can find more information about Primeo SolarAktiv here.
Optimise your own consumption.
The electricity you produce yourself is cheaper than electricity from the grid. With self-consumption, only your production costs are incurred, but no energy and grid utilisation costs or levies that you have to pay when purchasing electricity from the energy supplier. You can find more information on optimising self-consumption here.
The new regulation applies within the framework of the purchase and remuneration obligation in accordance with Art. 15 EnG. Plants larger than 150 kW or plants with special contracts are not affected. Plants that are part of special subsidy models, such as KEV or EVS, are also not affected.
Primeo Energie and AVAG generally apply the same remuneration rates for the voluntary purchase of energy from larger plants exceeding 150 kW.
The minimum remuneration is intended to ensure that installations can be operated economically in the long term. Larger installations with a capacity of over 150 kW are generally already competitive without guaranteed minimum remuneration. They are therefore not covered by the minimum remuneration.
Those who generate electricity for their own consumption save a considerable amount of money. This is because every kilowatt hour of electricity that is generated and used does not have to be purchased from the local grid operator. In addition, larger systems can be operated more economically. Medium-sized systems with own consumption are therefore treated in such a way that the guaranteed minimum remuneration decreases as the system output increases.
Electricity from systems with a capacity of between 30 and 150 kW that feed exclusively into the grid, on the other hand, is remunerated at a fixed rate of at least 6.2 pence per kilowatt hour, as these systems do not allow for savings through own consumption.
Electricity fed into the grid from plants under 30 kW is always remunerated at a minimum of 6 pence per kilowatt hour, as the issue of own consumption is irrelevant for these small plants.
No, the minimum remuneration only applies in quarters in which the reference market price falls below the minimum remuneration threshold. If market prices are higher, the higher prices will continue to be paid out as before. The minimum remuneration therefore provides protection against downward price movements without capping prices at the top end. If prices are high, as will be the case in 2022, for example, owners of PV systems will continue to benefit in full.
The feed-in tariff remains dependent on market fluctuations. Due to the minimum tariff, plant performance now also plays a role in determining how much producers receive for the electricity they supply each quarter.
In general, plant owners can expect to receive a certain amount of income even in quarters with low market prices. The amount of additional income in pounds and pence compared to the previous model depends on the amount of electricity produced and the market price. The lower the market price, the more plant owners benefit from the guaranteed minimum remuneration.
Taking 2025 as a benchmark, if the minimum remuneration had already been in place, it would have come into effect in both the second and third quarters (for small systems under 30 kW).

If you and your neighbour supply energy to Primeo Energie, Primeo Energie will pay the same rates for comparable plant sizes. The remuneration consists of a remuneration for the physical supply of electricity and a remuneration for the ecological added value of the production (HKN remuneration).
Active participation by the producer is required for the HKN remuneration. However, a producer can also offer their energy to a third-party energy supplier who can pay a different feed-in tariff.
The return delivery to us can be terminated with one month's notice to the end of the quarter.
Primeo Energie is not the right addressee for political statements. These must be addressed to the federal government, parliament and the authorities. As a network operator, we are obliged to comply with the legal requirements that have been passed.
Looking at the development of reference market prices since 2024, prices for the summer quarters are well below 6 cents/kWh, at which point the minimum remuneration applies. The minimum remuneration values are calculated by the SFOE. They are based on the amortisation of reference installations over their lifetime and are set out in Article 12(1bis) of the Energy Ordinance.
Yes, you can. Please contact your installer.
As a rule of thumb, producers with a photovoltaic system who increasingly use the production peaks around midday to cover their own consumption and whose photovoltaic system has a production focus in winter will benefit by up to 30 per cent compared to the standard tariff (see also information on the optional tariff under Downloads). For existing systems, the past load profile can be used to analyse whether the optional tariff is worthwhile.
No, owners of electricity generation plants can also sell the electricity generated to third parties.
The return delivery may be terminated with 30 days’ notice to the end of a quarter. Return deliveries to Primeo Energie/Aare Versorgungs AG (AVAG) may be resumed within the same period at the beginning of a quarter and must be notified by email to pva@primeo-energie.ch.
No, but Primeo Energie/Aare Versorgungs AG (AVAG) accepts guarantees of origin as standard if all documents are available in accordance with the price sheet.
Remuneration of guarantees of origin
Remuneration for guarantees of origin begins in the next calendar month after the documents relevant for payment have been submitted. These are 1) authentication (activation of the system for issuing guarantees of origin) and 2) confirmation from Pronovo that the standing order entered online for guarantees of origin has been set up in favour of Primeo Energie/Aare Versorgungs AG (AVAG). Guarantees of origin are only accepted if the active energy is also fed into our grids and remunerated.
In principle, yes. Producers and grid operators are free to agree on the amount of the redelivery fee. However, in the event that they do not reach an agreement, there are minimum legal requirements. The remuneration for energy from renewable sources and biogas fed into the grid is then based on the avoided costs incurred by the grid operator for the procurement of equivalent electricity in accordance with energy legislation. For electricity from partially or fully fossil-fuelled combined heat and power plants (CHP plants), the redelivery remuneration is based on the spot market price at the time of feed-in to the grid (www.epexspot.com, day-ahead action with the corresponding euro exchange rates). Primeo Energie/Aare Versorgungs AG (AVAG) regularly reviews the redelivery fee and adjusts it upwards or downwards in the event of changes.
As an electricity supplier, we are obliged under Art. 15 of the Energy Act to purchase electricity from renewable energies in our own grid area and to remunerate it appropriately, provided that no direct marketing takes place. The amount of the re-delivery remuneration for active energy at Primeo Energie is based on the avoided procurement costs for equivalent energy in accordance with Art. 12 of the Energy Ordinance. We regularly review the redelivery fee and adjust it upwards or downwards in the event of changes. Unfortunately, we cannot provide any information on the calculations of other grid operators.

The amortisation period indicates the point in time when operating your own photovoltaic system starts to pay off. For a typical photovoltaic system with an output of 10 kilowatt-peak (kWp), in other words, around 25 modules, this takes between 10 and 20 years. The amortisation period depends on the interaction of various factors, such as the share of own consumption, the energy supplier’s electricity tariff, any subsidies that may apply, and the return delivery remuneration for the electricity fed into the grid. Incidentally, the amortisation period of a photovoltaic system is often confused with its service life. In most cases, the service life of photovoltaic modules is much longer, around 30 to 40 years.
In principle yes, you do. You can ask the relevant tax authority directly how the feed-in remuneration for your photovoltaic system is to be taxed. Please refer to your canton’s instructions for completing your tax return.
Primeo Energie/Aare Versorgungs AG (AVAG) will gladly provide you with a tax statement for the energy fed into the grid for your tax return.

Frequently asked questions about guarantees of origin
Guarantees of origin (GOO) are certificates that are dissociated from the active energy fed in (physical current flow). The certificates are issued by Pronovo AG for the respective electricity producer and traded independently. Guarantees of origin are used to make the origin of electricity transparent to the end consumer. A guarantee of origin is issued for every kilowatt hour of electricity produced.
Guarantees of origin are also the ecological added value of the active energy you feed in.
Producers with systems between 2-30 kWp that have been certified can assign their guarantees of origin to Primeo Energie by means of a standing order. System certification is necessary for guarantees of origin of the energy the system generates. Primeo Energie does not accept guarantees of origin for systems of less than 2 kWp or more than 30 kWp. Please contact your solar engineer/installer directly in these cases.
A standing order for your guarantees of origin is voluntary. By placing a standing order with Primeo Energie/Aare Versorgungs AG (AVAG), you will receive additional ecological value in addition to active energy. The active energy is paid out independently of a guarantee of origin standing order.
As soon as your system has been certified and meets the requirements, Primeo Energie/Aare Versorgungs AG (AVAG) will enter a standing order for guarantee of origin transmission in Pronovo AG’s guarantee of origin system. You will receive an email from Pronovo AG informing you that this standing order has been entered and you can confirm the standing order directly. Acceptance of this standing order is necessary so that you can receive the ecological added value. If you do not wish to do so, you can ignore the email and the previously entered standing order will be void.
Remuneration for ecological added value begins from the next calendar month, once your system has been certified and the guarantee of origin standing order confirmed.
Pronovo AG is a subsidiary of Swissgrid and subject to supervision by the Swiss Federal Office of Energy (SFOE) in connection with issuing guarantees of origin. It is the accredited certification body for issuing guarantees of origin.
The HKN remuneration amounts to up to 2.00 pence/kWh. Primeo Energie reserves the right to regularly review and adjust the HKN remuneration. In particular, it reserves the right to reduce it if the total remuneration for electricity and HKN remuneration exceeds the plant-specific remuneration limit, known as the eligibility limit.
For photovoltaic systems, the eligibility limits are set as follows:
PVA with own consumption with a capacity of less than 100 kW: 10.96 pence/kWh
PVA with own consumption with a capacity of 100 kW or more: 7.2 pence/kWh
PVA without own consumption with a capacity of less than 100 kW: 8.2 pence/kWh
PV systems without self-consumption with a capacity of 100 kW or more: 5.4 pence/kWh
