Before the forecast_date
Chellow uses data in the
database (if any), and after that date it uses data from the same
month but in the year before the forecast_date
.
If a rate script isn't found for a particular date, then the most recent rate script is used.
Virtual bills can include TRIAD estimates and actuals in a variety of ways. For example, a virtual bill may use TRIAD estimates for all months until triad dates are available for that financial year, in which case it switches to using the actual TRIAD for March.
TRIAD estimates are calculated using the actual TRIAD from the latest historical year for which we have TRIAD dates. Historical kW and status are used, together with current LAFs and TRIAD rates, with the result apportioned throughout each month.
Taking 'generated' as an example, for each half-hour Chellow will
calculate the difference between the scenario_generated
and the existing_generated
. If
scenario_generated
>= existing_generated
then any imported_net
will be reduced first, then
exported_net
will be increased until all the difference
is exhausted. Otherwise if scenario_generated
<
existing_generated
then exported_net
will
be reduced first, and then imported_net
will be
increased. A similar approach is taken with used, parasitic and
gen_net kWh.
The method is the same for months after the
forecast_date
but with the
existing_generated
being found from the default
forecast.
