Nordpool Rate Limits

Nord Pool does not publish fixed numeric rate limits for the Market Data API in its public OpenAPI definition or marketing pages. Access is gated commercially rather than by request-rate tiers - each Power Data Services subscription includes one OAuth 2.0 API account (additional accounts EUR 350 per year), and the scope of data returned is bounded by the packages purchased (for example, the day-ahead-price-only package limits history to the last 8 days). The Intraday Trading API is governed by STOMP heartbeat requirements and per-member onboarding rather than published request caps. The unofficial public Data Portal API has no published limits but is served behind CDN protection that blocks non-browser clients without proper headers, and should be polled gently.

Nordpool Rate Limits is the machine-readable rate-limit profile for Nord Pool on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 5 rate-limit definitions, measuring requests, accounts, history, and connections.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Day-Ahead Prices, Electricity, Energy Markets, Power Exchange, and Rate Limiting.

Limits

Market Data API Requests account
requests
not published
No numeric request-rate limit appears in the published OpenAPI definition.
API Accounts per Subscription subscription
accounts
1 included
One OAuth API account included per customer across all subscriptions; additional accounts cost EUR 350 per year.
Data Scope subscription
history
per package
Data coverage and history depth (for example 8 days on price-only packages, back to 1992 on full packages) are set by the purchased package, not by request quotas.
Intraday Trading API Sessions member
connections
per onboarding
WebSocket/STOMP sessions require member credentials from idapi@nordpoolgroup.com; heartbeats must be maintained and access tokens refreshed on live connections.
Public Data Portal API anonymous
requests
not published
Unofficial endpoint with no stated quota; aggressive polling risks being blocked. Prices publish once daily around 13:00 CET, so more than a few requests per day is rarely useful.

Policies

Commercial Gating
Access control is primarily commercial (annual data fees and trading membership) rather than technical request-rate tiers.
Backoff Strategy
Clients should implement exponential backoff with jitter and honor any Retry-After headers on 429 or 5xx responses.
Publication Cadence
Day-ahead auction results are published once per day after the market coupling session completes; schedule fetches to the publication window instead of continuous polling.
