Day-ahead wind and solar generation forecasts: the TSO official forecast and Voltcast model with uncertainty bands, realized generation, and disclosed head-to-head verification. Requires the corresponding existing account entitlement.

}🟢cheapest_window(zone, duration_minutes, from, to, count, ...)
Rank household action windows by cost using current Voltcast curves and optional user-supplied variable tariff inputs. Experimental carbon/balanced modes use a disclosed trailing historical production-mix profile—not a forward carbon forecast—and support no emissions-reduction claim.
