# Create Site Measurements

`POST /resources/wind_power_site_measurements`

Submit measurement data for a Premium Wind Power site. Measurements are used for model training. Maximum 1000 measurements per request. Power units (AC) are measured in MW. Power is the actual measured power output by the site. If there are availability and curtailment constraints in place, those fields should also be included with the measurements.

## Request body

- CreateWindSiteMeasurements — Create Site Measurements
  - `measurements` ApiWindSiteMeasurement[] — Array of measurement records (1-1000).
    - `availability` number, double, nullable — Availability percentage (0-100).
    - `curtailment` number, double, nullable — Curtailment ceiling in MW.
    - `period` string, nullable — Duration of the measurement period (ISO-8601 duration, e.g., PT5M). Either 'period' or 'period_start' is required.
    - `period_end` string, date-time — End of the measurement period (ISO-8601 with timezone, exclusive).
    - `period_start` string, date-time, nullable — Start of the measurement period (ISO-8601 with timezone, inclusive). Alternative to 'period'.
    - `power` number, double — Power output in MW.
    - `wind_direction_hub_height` number, double, nullable — Wind direction at hub height in degrees (0-360).
    - `wind_speed_hub_height` number, double, nullable — Wind speed at hub height in m/s.
  - `resource_id` string, required — The unique identifier of the Premium Wind Power resource.
