# Create a cluster

> Creates a cluster grouping multiple locations under a single optional
kW cap. All `locationIds` must belong to the calling tenant.




## OpenAPI

````yaml /api-reference/energy-management/openapi.en.yaml POST /clusters
openapi: 3.1.0
info:
  title: RiDERgy Energy Management API
  version: '1.0'
  license:
    name: Proprietary
    identifier: LicenseRef-Proprietary
  description: >
    Programmatic control of charging power limits across locations, individual

    chargers, organizations, and cross-location clusters.


    ## Authentication

    Every endpoint except `GET /health` requires an `x-api-key` header. The key

    determines your tenant — it is never read from the request body or any other

    header, so a key for one tenant cannot access another tenant's data.


    Your tenant must have the Energy Management API feature enabled, otherwise

    requests fail with `403 FEATURE_NOT_ENABLED`. Contact RiDERgy to enable it.


    ## Priority model

    Location and charger limits are controlled via **priority-windowed
    profiles**:


    - Priorities range from **0 (lowest) to 10 (highest)**, OCPP-stack-style.

    - A target (location or charger connector) can have up to 11 profiles, one
      per priority level, each with its own `[startTime, endTime)` window.
    - At any moment, the **effective limit** is the `limitKw` of the
      highest-priority profile whose window is currently active.
    - If no profile is active, a location falls back to its `permanentLimitKw`.

    - Submitting a profile at a priority that already has one for that target
      **replaces** it.
    - Profiles are applied and reverted automatically at their
      `startTime`/`endTime` — no further API calls are needed once a profile is
      created. Profile records are never deleted, so history remains queryable.

    ## Errors

    All errors share this shape:


    ```json

    {
      "error": {
        "code": "LOCATION_NOT_FOUND",
        "message": "Location 123 was not found for the provided tenant",
        "requestId": "b1f6e6b0-..."
      }
    }
