The links preselect this utility. EV charging opens the recurring charging-window profile; other tools keep an explicit verified-period selection unless their own schedule model applies.
Rate version & freshness
This tariff snapshot is versioned and source-attributed. When a verified rate changes, CalcuRiver keeps this version in history and adds a new one instead of silently overwriting it.
