Prelko
Grid Performance Reports

Proof that the forecast is getting better.

Prelko scores every forecast interval against what actually happened and tracks how peaks, recommendations and balance outcomes trend over weeks and seasons. The same numbers go to the control room, management and the regulator.

Reporting questions

Can we compare Prelko against our current forecast?

Yes. Upload or connect your existing forecast and Prelko scores both against the same actuals, side by side.

How long is report history kept?

For the life of your subscription. Everything can be exported at any time, including when you leave.

Can reports match our regulator's format?

Standard templates cover common accuracy and deviation summaries. On the Utility plan we configure custom report layouts during onboarding.

Benchmark your current forecast.

Send us a quarter of forecasts and actuals, and we will score them on the same metrics Prelko reports on.
