# Upload energy data {% hint style="info" %} You can only upload energy data after your project has been approved by your registry {% endhint %} RECs are issued against energy produced by a renewable source. To transform renewable energy into RECs, users upload their *energy data* to Fuel Switch. We refer to *energy data* when describing the readings (kWh and timestamp) captured by meters of renewable energy sources (aka. renewable energy projects). Energy data is always associated to a single, specific meter of a renewable project. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
