Can EnergyPlus report the time of utility tariff peak demand?

It's often the case when using tariffs with time of use demand charges that the building's peak demand profile is different than the utility's peak demand profile because the building's peak occurs outside of the utility's peak demand window (see chart below).

The building's absolute peak demand time can be reported from the Electricity:Facility Meter, but can the utility tariff's? Context is determining peak shifting for grid-interactive efficient buildings (GEB).
