The average hourly electricity price for Finnish consumers will rise to a peak of 12.3 cents per kilowatt-hour on Wednesday, including a 25.5% value-added tax. [^1]

In a five-dataset electricity-price setting, the CastClaw authors report the lowest point-estimate MSE and MAE among 16 baseline models. [^2]

In the arXiv preprint 2608.30976 submitted on 31 August 2026, the authors present CastClaw, a human-in-the-loop autonomous forecasting system built through forecasting-oriented harness engineering. [^3]

The highest hourly price of the day is expected at 10:00 on Wednesday, while the lowest price is 4.4 cents per kilowatt-hour at 3:00. [^4]

The Nord Pool electricity exchange transitioned to a 15-minute pricing model starting from the beginning of October 2025. [^5]

According to the CastClaw authors, starting from a supplied or model-generated forecast, the system checks temporal patterns and user constraints, and when evidence is missing it retrieves context, runs an analysis or another model, or asks the user. [^6]

The CastClaw paper states that it was validated offline on provincial electricity-load data from North China covering January to June 2026, and that a Nord Pool case demonstrates the inspectable workflow. [^7]
