Rebase Grid API

Open REST API for European power system and electricity market data: day-ahead prices, load, generation by type, wind and solar forecasts, cross-border flows, balancing and grid frequency. The data comes from ENTSO-E, TSOs and exchanges, in one schema.

No API key needed. Every endpoint answers without a key at 30 requests per minute. A free key raises the limit to 240 per minute.

Try it

Day-ahead prices for Germany-Luxembourg, one day. This works as it is:

curl "https://grid.rebase.energy/api/v1/entities/DE-LU/timeseries/price.day_ahead.day_ahead_auction_price/values?provider=entsoe&start=2026-11-09T00:00:00Z&end=2026-11-10T00:00:00Z"

{
  "entity": "DE-LU",
  "name": "price.day_ahead.day_ahead_auction_price",
  "provider": "entsoe",
  "unit": "EUR/MWh",
  "resolution": "PT15M",

  ]
}

Python

pip install rebase-grid-api

from rebase_grid_api import GridAPI

grid = GridAPI()   # no key needed; GridAPI(api_key="...") for 240 requests per minute

# one timeseries as a pandas Series, indexed by UTC time
prices = grid.values("DE-LU", "price.day_ahead.day_ahead_auction_price",
                     start="2026-11-01", end="2026-11-08")

# several years in one call: the client splits the range into requests for you
load = grid.values("DE-LU", "consumption.realised_load.total_load",
                   start="2023-01-01", end="2026-07-01")

grid.search("SE-SE3", category="price", q="day-ahead")   # find timeseries names
grid.timeseries("DE-LU")                                 # everything on one entity
grid.entities()                                          # countries, zones, borders
grid.frequency()                                         # live grid frequency

The client waits and retries when the rate limit is reached, and picks the provider for you when only one organisation publishes a series. It is one file, src/rebase_grid_api/client.py.

The API is plain HTTP, so requests alone works too:

import requests

r = requests.get(
    "https://grid.rebase.energy/api/v1/entities/DE-LU/timeseries/price.day_ahead.day_ahead_auction_price/values",
    params={"provider": "entsoe", "start": "2026-11-01T00:00:00Z", "end": "2026-11-08T00:00:00Z"},
)
points = r.json()["points"]   # [{"valid_time": ..., "value": ..., "knowledge_time": ...}, ...]

What to ask for

Every call has the same shape: GET /entities/{entity}/timeseries/{name}/values?provider=…&start=…&end=…

Data	Entity	Timeseries name	Provider
Day-ahead price	DE-LU	price.day_ahead.day_ahead_auction_price	entsoe
Load (consumption)	DE-LU	consumption.realised_load.total_load	entsoe
Day-ahead load forecast	DE-LU	consumption.load_forecast.day_ahead_total_load_forecast	entsoe
Generation by type	DE-LU	production.realised_output.actual_generation_per_type.wind_onshore (also solar, nuclear, fossil_gas, …)	entsoe
Solar forecast	DE-LU	production.forecast.solar_generation_forecast.day_ahead	entsoe
Wind forecast	DE-LU	production.forecast.wind_generation_forecast.onshore_day_ahead	entsoe
Cross-border physical flow	border:FI~SE-SE3	exchange.physical_flow.physical_flow	entsoe
Grid frequency (live)	—	GET /views/frequency	—

Price zones use ids such as DE-LU, FR, SE-SE3, NO-NO1, DK-DK1. A name is the same in every zone.

Requests	30 per minute per IP address	240 per minute
Data	all	all
Points per request	100,000	100,000

When the limit is spent the API answers 429 with Retry-After and a message that says how to get a key. Request one here: https://rebase-energy.notion.site/3798f95cc39b802f8672eb93c6ab77c5?pvs=105 and send it in the X-API-Key header.

What you get

• Values as the provider published them: not filled, smoothed or estimated.
• Every value carries the time it became known (knowledge_time), and revisions are kept as versions. as_of returns the data as it was known at any past instant.
• Each response names the publisher's licence and the credit line to show.

Licence
