EV charging for underground car parks in the Canton of Appenzell InnerrhodenEvery space prepared.

No cantonal subsidy, clear requirements for the planning

We know of no cantonal subsidy for EV chargers in underground car parks in Appenzell Innerrhoden. The cantonal energy subsidy programme supports measures on buildings and renewable energy, but it does not mention charging infrastructure. Individual communes or the energy supplier may offer contributions, and we check this before the quote. If we find nothing, we calculate without a subsidy and tell you so.

House connection and cable routes

In smaller properties, the house connection often decides how many electric cars can charge at the same time. During the site visit we check the main distribution board, the cable routes to the car park and the available connection capacity. Load management shares the available power between the connected vehicles, so the connection is often enough for several spaces too. The quote then states how many charge points can run at the same time and what a later extension costs.

Owners’ association and landlord

In condominium ownership (STWEG), the owners decide according to the Civil Code and their regulations. Tenants need the landlord’s consent. We build the basic installation (backbone wiring) for all spaces once and add wallboxes when the need arises. Each charge point is metered separately, and users pay for what they use. The owners or the property management set the price per kilowatt hour.

Our planning principle is to build what is shared first and what is individual later. The supply cable, distribution and control are the same for all parties and are built once. Whoever has an electric car then installs their own wallbox, and the effort stays small for the other parties.

Grid operator

With its energy and water supply, the Feuerschaugemeinde Appenzell supplies four of the five communes at 27.6 ct./kWh. The cantonal median is also 27.6 ct./kWh, and the Swiss median is 27.7 ct./kWh. Our electrical installer registers the chargers with the grid operator under the Low-Voltage Installation Ordinance (NIV) before installation. We work with our own installers and plan everything through to commissioning, all from one source.
