Yes, your grid operator must take your solar electricity – and pay for it. The purchase and remuneration obligation is anchored in federal energy law: the utility can neither reject your system because it has "enough solar power" nor refuse remuneration. Since 2026 the amount is also regulated: at least the quarterly reference market price or the statutory minimum remuneration. (As of: July 2026)
Key points in brief
- Grid operators are legally obliged to take and remunerate electricity from renewable energies in their grid area – that isn't a courtesy but an obligation.
- This includes the grid connection: the utility must connect your system; it regulates the technical conditions via the connection application.
- Since 2026 the remuneration level is regulated nationwide: reference market price as standard, minimum remuneration as the floor – more is allowed, less is not.
- There are limits on the modalities: metering costs, technical requirements and the utility's deadlines are permissible and your duty as a producer.
- In a dispute, ElCom is the competent supervisory and conciliation authority – it can be contacted free of charge.
What exactly does the law guarantee you?
Federal energy law gives producers of renewable energy three solid claims against the local grid operator:
1. Connection: the utility must connect your system to its grid. It may set technical requirements (connection application, protection concept, meter), but may not refuse the connection outright. 2. Purchase: the electricity fed in must be taken – the utility cannot declare that it has no need. 3. Remuneration: the purchase must be paid for. Since 1 January 2026 the amount has been standardised nationwide: the standard is the quarterly reference market price, backed by the minimum remuneration for small systems. Utilities may voluntarily pay more – many do –, but not less.
This triad is the reason a solar system is a plannable investment in Switzerland: the sale of your product is legally guaranteed before you mount the first module.
What may the utility demand – and what not?
The purchase obligation is not a free pass; the utilities may regulate the modalities. Permissible and customary are:
| The utility may… | The utility may not… |
|---|---|
| require a connection application with technical documents | refuse the connection without objective reason or delay it indefinitely |
| set requirements for inverters, protective devices and metering | refuse to take the electricity because there is "enough solar power in the grid" |
| charge metering costs according to a published regulation | invent arbitrary fees that only hit producers |
| settle the remuneration according to its published model | fall below the statutory minimum remuneration |
| provide special conditions for very large systems | keep the guarantee of origin without paying for it (the GO belongs to you) |
Simplified overview, as of: July 2026 – what counts is the law, ordinances and your grid operator's published conditions.
In practice the connection is unspectacular: connection application before installation, approval by the utility, installation, acceptance with safety certificate, meter change – on ecoEn projects that is the standard process, not a matter for negotiation.
The sore point: deadlines and capacity
Where things actually get stuck is rarely the "whether" but the "when": connection applications need processing time, and in neighbourhoods with many new systems grid expansion can become a bottleneck – for example when the neighbourhood transformer is running at its limit. In such cases the utility may impose technical conditions (e.g. a limit on feed-in power at the connection point), but must offer a solution and may not block the project indefinitely.
Our practical advice: the connection application belongs at the start of project planning, not at the end. Anyone who obtains approval early builds waiting times into the project plan instead of waiting for the meter change with a fully installed system.
What to do if there is a dispute?
First: ask in writing and refer to the utility's published conditions – the great majority of differences are misunderstandings about metering costs, GO items or deadlines and are resolved at this level.
Second: if the conflict remains, ElCom (Federal Electricity Commission) is the competent supervisory authority – it monitors compliance with the connection, purchase and remuneration obligations and can decide with binding effect. For producers the procedure is low-threshold; even mentioning a possible ElCom enquiry speeds up some replies, in our experience.
Third: stay realistic. The utilities in the region work professionally – genuine cases of refusal are rare. The most common "disputes" we see are simply forgotten GO registrations or wrongly chosen tariff models, not legal violations.
The sentence "the utility doesn't want my electricity" reaches us a few times a year – and so far has turned out to be something else in every single case: an incomplete connection application, a query from the utility that landed in spam, or a power limitation at the house connection that was misunderstood as a refusal. Our routine: we submit the connection application with complete documents before the modules are ordered, and clarify the utility's queries directly at specialist level. Since we've handled it consistently that way, the "purchase question" is simply no longer an issue on our projects – it's answered by law.
Frequently asked questions
Can the utility reject my system because the grid is full?
In principle no – but it can impose technical conditions, for example a limit on feed-in power at the connection point until the grid is reinforced. A blanket, indefinite rejection is incompatible with the connection obligation.
Does the utility also have to take electricity from a system without self-consumption?
Yes – the purchase obligation applies regardless of whether you consume yourself or feed in fully. For full-feed-in systems, separate remuneration categories partly apply (overview).
Does the purchase obligation also apply to balcony power plants?
The surplus flowing into the grid is taken; whether and how micro-systems are remunerated and metered depends on the utility – below certain sizes the administrative effort often isn't worth it. Clarify this before buying.
Who bears the costs of the grid connection?
The costs of connection up to the connection point and any meters follow the utility's published connection regulation – they belong in every reputable quote.
Who do I turn to in a real conflict?
First in writing to the utility, referring to its published conditions. If that goes nowhere, to ElCom as the supervisory authority – its practice and FAQ cover the most common constellations.
