Hi! I’ve been learning about the Swedish electricity market and machine learning, so I built a tool to test what I learned:
Hourly spot prices for SE1–SE4, a 7-day forecast, the cheapest hours of each day, and the generation mix. Free, no login, no ads.
I’ve now put the forecast in a plain JSON file too, mostly so I could use it myself:
https://catch.unagieel.net/v1/forecast/SE3.json
(SE1, SE2 and SE4 work the same)
No key, no signup. What’s in it:
Today’s and tomorrow’s prices — settled, not guessed
The forecast 7 days out (Nord Pool only publishes day-ahead, so everything else stops at tomorrow)
Cheapest hours for each day
An 80% interval per hour, not just one number
What the forecast said before the price was known — so you can see how wrong I was
I’d be curious how people here actually use day-ahead prices or forecasts — what do you automate, and which apps or tools do you use for it? Hoping to pick up some ideas.
