Power and electricity data

Power and electricity data describes how electricity markets and grids operate: wholesale prices, demand, generation by fuel type, cross-border flows, outages and capacity. Power traders, utilities, renewable developers, battery operators, large energy users and analysts use it to forecast prices, schedule assets, value projects and hedge consumption.

Typical fields

• Market or bidding zone and settlement interval
• Day-ahead, intraday and imbalance prices
• Actual and forecast load
• Generation by fuel or technology
• Interconnector flows and available capacity
• Planned and unplanned outages
• Timestamps with an explicit time zone or UTC

Sources and methods

Transmission system operators, market operators and power exchanges publish most primary data, often through transparency platforms required by regulation, such as the ENTSO-E transparency platform in Europe or independent system operator websites in North America. Providers collect, clean and standardise this data and add derived series such as residual load, modelled output for unreported plants and price or load forecasts.

Delivery and pricing

Delivery is usually by API with history downloads, or as files and data shares for large archives. Licences are monthly or annual, priced by number of markets, granularity, forecast products and users. Exchange price data may carry separate exchange fees.

Before you buy

• Check how daylight saving changes and settlement period changes are handled.
• Ask whether history is point-in-time, including forecasts as issued.
• Confirm coverage of the bidding zones and nodes you trade.
• Review latency from source publication to availability.
• Ask how source revisions are recorded.
