⚡ Elexon BMRS GB Generation Scraper

🚀 Export Great Britain's live power mix in seconds. Pull actual electricity generation per fuel type straight from the official Elexon BMRS Insights API, with no key and no login.

🕒 Last updated: 2026-06-08 · 📊 5 fields per record · GB transmission grid · 11 fuel types per settlement period

Turn the Elexon BMRS Insights feed into clean, structured records you can drop into a dashboard, a model, or a warehouse. Pick a UTC time window and get one row per fuel type per 30 minute settlement period, showing exactly how many megawatts each source put onto the GB grid.

Coverage is the GB transmission system actual generation outturn (dataset AGPT) as Elexon publishes it: biomass, fossil gas, coal and oil, nuclear, hydro, pumped storage, solar, and both onshore and offshore wind, each tagged with its business type and settlement period.

🎯 Target Audience	💡 Primary Use Cases
Energy analysts and traders	Track the GB fuel mix period by period
Grid and renewables researchers	Measure wind and solar contribution
Data scientists and modellers	Feed generation series into forecasts
Sustainability and ESG teams	Report on low carbon generation share

📋 What the Elexon BMRS GB Generation Scraper does

This Actor calls the public Elexon BMRS Insights API and flattens the nested response into one clean record per fuel type per settlement period:

• Fuel breakdown — psrType such as Wind Offshore, Wind Onshore, Solar, Nuclear, Biomass, Fossil Gas, and more.
• Output level — quantity in megawatts for each fuel in each 30 minute period.
• Time context — settlement period number and the UTC start time of that period.
• Category — the business type Elexon assigns, like Production, Wind generation, or Solar generation.

You choose the UTC time window and how many records come back, and every record carries a scrapedAt timestamp.

⚙️ Input

Field	Type	Description
from	string	Start of the UTC time window in ISO 8601, for example 2026-06-06T00:00Z.
to	string	End of the UTC time window in ISO 8601, for example 2026-06-06T03:00Z.
maxItems	integer	How many records to return. Free plan is capped at 10.

Example 1 — a three hour window

{
    "from": "2026-06-06T00:00Z",
    "to": "2026-06-06T03:00Z",
    "maxItems": 50
}

Example 2 — a single early morning hour

{
    "from": "2026-06-06T01:00Z",
    "to": "2026-06-06T02:00Z",
    "maxItems": 11
}

⚠️ Good to Know: Elexon returns a settlement period only once the whole 30 minute period falls inside your window, and the most recent periods may lag real time by a short publishing delay. Widen the window or step back a few hours if a query comes back empty.

📊 Output

✨ Why choose this Actor

• One clean row per fuel per period, instead of a deeply nested payload you have to flatten yourself.
• Pulls straight from the official Elexon BMRS Insights API, the same source the GB market uses.
• No API key, no registration, and no login required.
• Megawatt values and settlement periods land in stable, database friendly field names.
• Onshore and offshore wind are reported separately, so renewable analysis is easy.

❓ Frequently Asked Questions

Do I need an Elexon or BMRS account? No. The Actor reads the public Elexon BMRS Insights API, which needs no login.

Do I need an API key? No key is required. The Actor sends a descriptive User-Agent as Elexon requests.

What does psrType mean? It is the power system resource type, in other words the fuel or technology, such as Wind Offshore, Solar, Nuclear, or Fossil Gas.

What is a settlement period? The GB market splits each day into 48 half hour settlement periods. Period 1 starts at midnight UTC, and each record shows the period number and its UTC start time.

Are the quantities in megawatts? Yes. quantityMw is the actual generation for that fuel during that settlement period, in megawatts.

Why did my window return nothing? A period appears only after its full 30 minutes fall inside your window, and very recent periods may not be published yet. Widen the window or move it back a few hours.

Are onshore and offshore wind separated? Yes. They come back as distinct psrType values, Wind Onshore and Wind Offshore.

Which grid does this cover? The Great Britain transmission system actual generation outturn published by Elexon.

How fresh is the data? Each run pulls live from the Elexon BMRS API, so it reflects what has been published for your window at run time.

Can I schedule this? Yes. Use Apify Schedules to snapshot the GB fuel mix on any cadence.

🔌 Integrate with any app

Results are available through the Apify API, so you can pull them into any app, database, or workflow you already run.
