Shorter settlement periods moved value below six hours
European and Asian markets have shortened imbalance settlement toward fifteen minute periods, which makes a deviation over a short window financially consequential in a way an hourly average never was. Numerical weather prediction cannot resolve that horizon usefully, so value moved to methods built on live turbine data, satellite imagery and upstream sensing that were previously academic curiosities. Nowcasting grows at 17.4% against a market rate of 11.6% for that reason alone. Vendors built entirely around weather modelling are watching the growth go somewhere their core capability does not reach.
