description: >-
  The ENTSO-E Transparency Platform web API has exactly one plan - free with
  registration. The platform is a regulatory publication mandated by EU
  Regulation 543/2013, so the data itself carries no charge and there are no
  paid tiers, quotas for sale, or commercial upgrades. Access is gated only by
  an account: register on transparency.entsoe.eu, email transparency@entsoe.eu
  with "Restful API access" in the subject line (the helpdesk targets a
  response within 3 working days), then generate a personal security token
  under My Account Settings. Consumption is bounded by fixed technical limits
  (400 requests/minute per IP/token, one-year range per standard query,
  100-200 documents per document-based query) rather than by billing.
notes: >-
  The same account also grants access to the ENTSO-E File Library for bulk
  file downloads at no charge. Tokens can be reset by the user at any time if
  compromised.

    load, generation, balancing, transmission, outages, and congestion data -
    after free registration and issuance of a security token. No payment
    method, contract, or usage fee at any volume; only the platform's fixed
    technical limits apply.
