# Restoration Zone Demand Restored Submissions (RZDR)

`GET /demand/by-restoration-zone/restored/submissions`

This endpoint provides data about the end of system restoration events. It returns the restored demand value
for each restoration zone at the last submission time of each event. The number of events to return is
determined by the `count` parameter.
            
The data can be filtered by submission date/time, region, and GSP Group ID (when received by NESO).
            
All DateTimes should be expressed as defined within
<a href="https://datatracker.ietf.org/doc/html/rfc3339#section-5.6" target="_blank">RFC 3339</a>.

Some examples of parameter combinations are shown below.
