Energy Banking
/Energy Accounting
-
If the Consumer does not claim the
renewable attribute of wind/solar for
meeting its Solar/Non-Solar RPO,
energy injection worked out at the
receiving end sub-station of GETCO will
be set-off against the consumption
during the Consumer's billing cycle.
If the consumer claims the renewable
attributes of solar/wind for meeting its
solar/non-solar RPO, then energy
accounting will be based on 15-
minute time block-basis.
In both the cases, surplus power, after
giving set off, will be purchased by
DISCOM at Average Pooled Power
Purchase Cost (APPC) of the year of
commissioning of the project.
Surplus power, after giving set off, will
be purchased by the DISCOM at 85%
of Average Pooled Power Purchase
Cost (APPC) of the year of
commissioning of the project.
Banking of 100% of energy will be
permitted during all 12 months of the
year, based on the feasibility and prior
approval of APTRANSCO/APDISCOMs.
Banking charges will be adjusted in
kind at 5% of the energy delivered at
the point of drawl.
The unutilized banked energy shall be
considered as deemed purchase by
Discoms at 75% of the Average Pooled
Power Purchase Cost as determined by
the APERC for the applicable year.
