Wind & Solar Forecasting

Wind and solar forecasts are generated by separate meteorological models and delivered as static files that do not update within the trading day. When generation deviates from schedule during ramp events or curtailment windows, traders and balance responsible parties have no automated mechanism to detect the deviation early and adjust nominations before imbalance penalties accrue.

Lumina Analyst
Are there ramp or curtailment risks in the next 24 hours I should re-nominate for?

A wind down-ramp of about 180 MW over 90 minutes is forecast around hour 14 as a front passes, and the ensemble spread is widest at hours 13-15, signalling the highest schedule risk of the day. Holding the current nomination through that window exposes roughly EUR 28k of imbalance penalty at today's balancing prices. Recommend trimming the afternoon nomination by 120 MW and buying back intraday before gate closure.
