Day-ahead electricity price forecast

The price forecasts

Day-ahead, 12 days out. Updated six times a day, so it gets sharper the closer you get to gate closure time (GCT).

Energy Trading

Price forecasts for trading desks operating in Nordic and Baltic power markets.

Energy Utility

Price forecasts for production planning — whether you're are balance responsible party (BRB) or coordinating with one.

Energy Optimization

Forecast inputs for multi-market optimization trading algorithms.

Heavy Industry

Forecasts for energy-intensive production scheduling — and the value of your own side-stream generation.

How often are day ahead forecasts published?

The day-ahead forecast is updated six times a day, every day. After day-ahead prices are published for the next electricity market day, forecasts are refreshed on this schedule (CET):

~15:00
19:00

next morning
06:00
07:30
08:30
10:00 (currently our last day-ahaed forecast before GCT)

Need updates more often? We can increase the frequency on request.

What period does the forecast cover, and at what resolution?

The forecast covers 12 days ahead, starting from the last known day-ahead price, available at hourly and 15-minute resolution.

How is the probability forecast generated, and what's it based on?

We generate probabilistic forecasts by running our model thousands of times with randomized variation, then applying a quantile-dependent loss function. All forecasts use the same input data — so the high, low, and median values reflect the model's internal uncertainty, not uncertainty in external variables like weather or demand.

During training, the low and high bounds represent the 10th and 90th percentiles. In practice, for the first forecast day, they typically land closer to the 25th and 75th percentiles.

What bidding zones do you cover?

Currently covered:

Finland (FI)
Estonia (EE)
Latvia (LV)
Lithuania (LT)
Poland (PL)
Sweden — SE1 & SE3

What data sources power the forecasts?

Weather observations and forecasts
Urgent Market Messages (UMMs) — transmission, production, and consumption unavailabilities
Fuel prices
Hydrological conditions
Actual production by generation type
