Register a PV system for companies | BKW

Registration and approval

The process starts before the installation is built

For companies, PV systems are often larger. That is why the grid connection, feed-in capacity, metering concept and remuneration model should be clarified at an early stage.

Registration is usually carried out via your specialist partner. They submit the technical documents and coordinate the necessary steps with BKW. BKW checks whether the desired installation can be operated and feed in at the existing connection. Only after approval, construction, acceptance and the meter/measurement concept can surplus electricity be fed in and remunerated.

Registration process

How companies register their PV system

From the initial assessment to remuneration: the key steps for feed-in and billing.

The exact process depends on the system size, connection capacity, metering concept and desired remuneration model. Your specialist partner will support you with the technical registration.

Step 01

Plan system and usage

Clarify PV capacity, self-consumption, feed-in capacity, battery storage, EMS, charging infrastructure and the desired remuneration model with your specialist partner.

Step 02

Submit technical connection application

Your specialist partner submits the necessary technical documents. BKW checks the connection, feed-in capacity and possible effects on the connection line and distribution grid.

Step 03

Await approval and any conditions

If grid or connection modifications are required, BKW will inform you about the next steps. For larger systems, this may extend the timeline.

Step 04

Build the installation and have it inspected

After approval, your specialist partner will build the system. Before commissioning, the installation and protection concept are checked and the required documentation is submitted.

Step 05

Activate metering and remuneration

After approval and correct metering, surplus electricity can be fed into the grid. Remuneration is provided according to the chosen model, for example feed-in remuneration or purchase remuneration.

Step 06

Report changes again

If you expand the system later, add storage or change the feed-in capacity, the relevant part of the process must be reviewed again.

Prepare remuneration

Factor in the remuneration model early on

Registration creates the technical basis. Which remuneration model makes economic sense should be examined in parallel.

For companies, feed-in remuneration, dynamic purchase remuneration, guarantees of origin or aggregation models may be relevant. Especially for larger systems with storage or an EMS, it is worthwhile coordinating self-consumption, feed-in times and billing at an early stage.
