# Providing Metering Data

> CSV format for uploading metering data to Otark

At Otark you can upload metering data to metering points and assign them to your assets & demands. The metering data is then shown on the asset/demand detail page (after getting access) and allows prospects and yourself to view & compare the data to see if an asset or demand would be a good fit.

To get the load data into Otark we currently support a manual CSV upload in the Otark admin.

  General Requirements
</h2>

* **One smart meter per file**: Each CSV file can only contain data for one smart meter. Uploading data for multiple smart meters via one file is not supported at this time. If this is a requirement please get in touch with us.
* Each row must represent a **15‑minute** measurement interval.
* The first row in the file must be a **header row** containing the column field names.
* **Field separator**: Semicolon (`;`).
* **Character encoding**: Automatically detected (use **UTF‑8** if unsure).
