National Grid ESO Data Portal: Live UK Grid Data for Carbon Intensity, Demand & Generation

The ESO Data Portal from National Grid PLC gives users direct access to live and historic electricity system data for Great Britain. It covers carbon intensity, demand forecasts, generation mix, and transmission constraints in near real time. The portal is designed for energy professionals, market participants, and researchers who need structured data via APIs or CSV downloads, with clear documentation and update frequencies for each dataset. Key datasets include balancing mechanism volumes, embedded wind generation, and interconnector flows. The portal has no paywall for most public datasets, but it assumes users are familiar with GB electricity market terminology. It is a practical tool for tracking grid performance, studying stress events, or building models around grid decarbonization and renewable integration.

This portal is actually useful if you work in UK energy. Carbon intensity data updates every 5 minutes, no paywall. Good for tracking how much gas gets called when wind drops.

I use the API for demand forecasts. It is raw but reliable. The documentation assumes you know the difference between transmission demand and distribution load, which filters out casual users.

The article says it is a bestseller that drives National Grid share price. That is a stretch. The portal is free and mostly used by analysts. It is not a revenue driver.

Worth noting that ESO is being separated from National Grid under UK legislation. The portal might move to the future independent system operator. That could change access terms.

I use the embedded generation dataset for solar output estimates. It is one of the few free sources for that data in GB. No registration needed, which is rare for grid data.
