Electricity Maps’ Post

📣 Starting tomorrow, European day-ahead markets adopt 15-minute time units, down from 60-minute intervals. This is the biggest change in the market in decades. At Electricity Maps, we love high granularity on electricity data. Our Historical and Real-time data have been available at 5- and 15-minute intervals since July of this year. Now, we're thrilled to announce that we’ve updated our day-ahead price Forecasts to match the 15-minute resolution across all European zones. This granularity brings forecasts closer to market needs, supporting more accurate trading and flexibility decisions. In the pictures, you can see (1) our Day-Ahead Price Forecasts getting smoother over the past few days, reflecting the new granularity, and (2) our API responses for the Day-Ahead Price endpoint returning 15-minute interval values.
