EV charging for underground car parks in the Canton of St. Gallen
What applies to your car park in the Canton of St. Gallen
Subsidy for underground car parks in the Canton of St. Gallen
The energy subsidy programme 2025 to 2030 supports charging infrastructure with load management in existing, non-public underground car parks. The connection, including protective devices, is subsidised with CHF 300 per space, at most CHF 25,000 and 35% of the investment cost. On top of this comes CHF 800 per space for at least four operational EV chargers. A single wallbox is not eligible.
Conditions for the application
The building permit for the car park must have become legally binding before 31 December 2020. For mixed use, the residential share must be at least 30%. You submit the application before the work is carried out. A photovoltaic system in the same project is supported with an additional flat rate of CHF 5,000. We clarify these points before the quote and submit the application for you.
Load management and condominium ownership
The programme requires load management that shares and prioritises the total charging power. That is exactly how we plan the charging infrastructure for all spaces. In condominium ownership (STWEG), the owners decide according to the Civil Code and their regulations, and in rented properties the landlord agrees. Since at least four EV chargers are needed, a joint decision that involves several parties at once is advisable.
The minimum of four EV chargers calls for the owners to act together. We record all parking spaces in the car park, agree the number of charge points with the property management and make sure the load management shares the total charging power by priority. Planning and installation are carried out by our own installers.
Grid operators in the Canton of St. Gallen
The St. Gallisch-Appenzellische Kraftwerke supply 15 communes at 29.3 ct./kWh, the St.Galler Stadtwerke are at 30.6 ct./kWh and the Regionalwerk Toggenburg at 24.8 ct./kWh. The cantonal median is 29.8 ct./kWh, against 27.7 ct./kWh for the Swiss median. Before installation, our electrical installer registers the system with the utility, and afterwards issues the safety certificate.

Frequently asked questions
Before you get in touch.
Is the site visit really free?
Yes. The visit and the quote cost you nothing and commit you to nothing. You only decide once you hold the binding quote in your hands.
How much does the Canton of St. Gallen subsidise charging infrastructure in an underground car park?
CHF 300 per space for the connection, at most CHF 25,000 and 35% of the costs, plus CHF 800 per space for at least four operational EV chargers.
Does St. Gallen give a subsidy for a single wallbox in the car park?
No, a single wallbox is not eligible. You need at least four operational EV chargers with load management.
By when must the underground car park in St. Gallen have been approved?
The building permit must have been issued before 31 December 2020. For newer car parks, we check other options.
Must property management allow every tenant an EV charger?
There is no clear legal entitlement. In practice, many property managers agree if the tenant bears the cost and the solution suits the building. A shared solution for all parking spaces is usually cheaper than many individual installations.
Who decides on EV chargers in condominium ownership?
That depends on the regulations and the scope. Work on shared parts such as the supply line and distribution board usually needs a resolution of the owners' meeting. We provide the documents for the vote.
Is the house connection enough for several electric cars?
Often yes, if load management shares out the power. Then not all cars charge at full power at the same time. We calculate whether the connection is enough using the load data of your building.
Which regions do you cover?
All of German-speaking Switzerland. We build most often in the cantons of Zurich, St. Gallen, Schwyz and Aargau. Our locations are in Zumikon ZH and Lachen SZ.
