# Grid operating data (EIA-930 / Elexon BMRS / NESO / Energinet / ENTSO-E / AEMO)

`GET /api/v2/energy/grid`

Grid operating data, provider-resolved by region: US balancing authorities (EIA respondent code, e.g. US48, PJM, CISO, ERCO) from the EIA-930 Hourly Electric Grid Monitor; GB from Elexon Insights (BMRS - demand outturn, day-ahead forecast) plus NESO (carbon intensity actual/forecast, embedded wind/solar forecast), half-hourly; DK1/DK2 from Energinet (hourly - demand, co2_intensity). DE_LU, FR, NL, ES, IT_NORD and PL from ENTSO-E Transparency at the published native resolution (demand and EUR/MWh day-ahead price). Operational data, preliminary and subject to revision; not for real-time grid operations.

## Query parameters

- `region` string — Region code: EIA balancing authority (US48, PJM, ...), GB, DK1/DK2, ENTSO-E zone (DE_LU, FR, NL, ES, IT_NORD, PL), or AU NEM region.
- `metric` 'demand' | 'demand_forecast' | 'net_generation' | 'total_interchange' | 'co2_intensity' | 'co2_intensity_forecast' | 'embedded_wind_forecast' | 'embedded_solar_forecast' | 'price'
- `frequency` 'hourly' | 'local_hourly'
- `start` string, nullable — Lower bound on period (ISO 8601 or EIA YYYY-MM-DDTHH).
- `end` string, nullable — Upper bound on period.
- `limit` integer — Maximum observations returned. History metrics: newest first. GB forecast metrics: nearest future periods first (chronological from now, or from an explicit start - pass a past start to read superseded forecast values).

## Response `200`

Successful Response

- EnvelopeGridRegionFeed
  - `data` GridRegionFeed, required
    - `query` GridQuery, required
      - `region` string, required — Region code: EIA balancing authority, GB, DK1/DK2, ENTSO-E zone (DE_LU, FR, NL, ES, IT_NORD, PL), or AU NEM region.
      - `metric` string, required — demand | demand_forecast | net_generation | total_interchange | co2_intensity (GB/DK) | co2_intensity_forecast (GB) | embedded_wind_forecast (GB) | embedded_solar_forecast (GB) | price (AU NEM or ENTSO-E).
      - `frequency` string, required — hourly (UTC) | local_hourly (local time). US regions only.
      - `start` string, nullable — Lower bound on period (ISO 8601 or EIA YYYY-MM-DDTHH).
      - `end` string, nullable — Upper bound on period.
      - `limit` integer, required
    - `region` string, required — Region code echoed back (EIA respondent, GB, DK1/DK2, ENTSO-E zone, or AU NEM region).
    - `region_name` string, nullable
    - `metric` string, required
    - `type_code` string, required — Underlying source dataset code: EIA type facet (D | DF | NG | TI), BMRS dataset (INDO | NDF), Energinet column (GrossCon | CO2PerkWh), NESO series (CI_ACTUAL | CI_FORECAST | EMBEDDED_WIND | EMBEDDED_SOLAR), ENTSO-E document type (A65 | A44), or AEMO dispatch column (TOTALDEMAND | RRP).
    - `unit` string, nullable
    - `resolution` string, nullable — Native series resolution for non-US regions. Null means the source payload contains mixed native resolutions.
    - `count` integer, required — Number of observations returned.
    - `series` GridObservation[], required
      - `period` string, nullable — Reporting period. US: EIA hourly YYYY-MM-DDTHH (UTC unless frequency=local_hourly); GB/DK/EU/AU: full ISO instant YYYY-MM-DDTHH:MM:SSZ at the native resolution.
      - `value` number, nullable — Metric value; null if the source omitted it.
    - `attribution` GridAttributionSet, required
      - `sources` GridSourceAttribution[] — Every sovereign source that contributed to this response.
        - `registry_key` string, required
        - `source_name` string, required
        - `licence` string, required
        - `citation` string, required
        - `disclaimer` string, required
      - `effective_reexport` string, required — Most-restrictive re-export verdict across the sources.
    - `disclaimer` string, required
  - `meta` SugraMeta, required — Metadata attached to every /api/v1/* response envelope.
    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `401` — Missing or invalid `x-api-key` header.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
