RTE Data Portal

What you can build

• Turn an Ecowatt alert into a curtailment plan

  Read the Ecowatt signal and the consumption forecast, and draft a load-shedding window for your French sites checked against meters and equipment state. You approve before anything changes.

  With Event Response

• Pre-cool before the Peak Period signal

  When the Signal API issues a Peak Period notice on D-2 or D-1, propose pre-cooling and staged loads for the flagged hours within comfort limits.

  With Peak Demand

• Schedule the battery on French hub prices

  Combine Wholesale Market prices with the site load forecast and battery state of charge, and propose tomorrow's charge and discharge blocks for sign-off.

  With Battery Dispatch, Price Shift

Requirements

• An account on data.rte-france.com and one declared application, with a subscription to each API you read
• Date parameters in the form YYYY-MM-DDThh:mm:sszzzzzz with the time zone included
• A retry that honours the Retry-After header on HTTP 429
• The source named wherever public data is reused, as the general terms require

Authentication

OAuth 2.0. You create a free account, declare an application on the portal to receive token-type client logins, and send the resulting token as Authorization: Bearer on each call.

Limits

• Each organisation has a maximum number of calls; exceeding it returns HTTP 429, and RTE advises one call per hour for the hourly generation resources
• Period caps per resource: 155 days for generation by production type, 7 days per unit, 366 days for water reserves and the 15-minute mix
• A response over 7 MB returns HTTP 413 and a URI over 2048 characters returns HTTP 414
• EPEX SPOT and Nord Pool figures in the Wholesale Market API are for internal use; commercial reuse needs their written consent

Questions and answers

How do you authenticate against the RTE APIs?

With OAuth 2.0. After creating an account you declare an application on the Data Portal and receive token-type connection logins, which you can reset yourself. Each request carries the token in an Authorization: Bearer header. A 401 means the token is missing or expired.

Is there a call quota?

Yes. The user guide describes a check that the caller's organisation has not exceeded its maximum number of authorised calls; if it has, the API returns HTTP 429 with a Retry-After header in seconds. RTE also recommends one call per hour for the hourly Actual Generation resources.

Can you reuse the data?

Public data may be reused provided the source is mentioned, under the portal's general terms. Power exchange data from EPEX SPOT and Nord Pool is their property and may be used internally only; commercial use or derivative instruments need their written consent.
